The amount of drainage is measured using a graduated cylinder and a stopwatch to measure the amount of water drained through the pipeline, and the lift pressure is measured by manually closing the valve provided in the pipeline, The measurement was performed by reading the indicated value of a Bourdon tube pressure gauge provided in the above.

In order to measure such drainage and lifting pressure,
Pipelines communicating with a plurality or a large number of drain holes are laid in the audit corridor, and a pressure gauge and a valve are attached to each of these pipelines. And the amount of wastewater per minute is calculated.

〔Example〕

Hereinafter, embodiments of the present invention will be specifically described with reference to the accompanying drawings.

FIG. 1 is a front view showing the lifting pressure of a levee body behavior observation device according to the present invention, the lifting pressure of a drainage amount measurement device, and the piping state of a drainage amount measurement unit.

In FIG. 1, reference numerals 1a and 1b denote drain pipes, respectively. Although not shown in FIG. 1, a large number (75 in this example) of drain pipes 1 laid in an embankment inspection corridor.
Are shown on behalf of two of them. One end of each of these drain pipes 1 is connected to a drain hole formed in the embankment inspection corridor, and the other ends of the drain pipes 1a and 1b are connected via pipes 2a and 2b. It is connected to the water collecting pipe 3.

The pipes 2a and 2b are provided by the number of drain holes, and each pipe 2a and 2b is formed into an arbitrary shape by appropriately connecting a curved pipe and a straight pipe as shown in FIG. I have.

The drainage from the drain hole is collected in one water collecting pipe 3 through the drain pipes 1a and 1b and the pipes 2a and 2b from each drain hole. Valves 4a and 4b, which are manually opened and closed, for example, including ball valves, are arranged at positions close to the drain pipes 1a and 1b, respectively.

In the following description, based on FIG. 1, 75 drain holes,
The description will be made with two drain pipes and conduits.

Valves 5a and 5b, which are also manually opened and closed and are similarly formed as ball valves, are provided at positions near the water collecting pipe 3 in the pipe lines 2a and 2b.

In addition, Bourdon tube type pressure type 7a, 7b is provided at a substantially central portion of each of the pipelines 2a, 2b via valve cocks 6a, 6b, respectively, so as to indicate the pressure in the pipelines 2a, 2b. It has become.

In the pipe line 2a, a lifting pressure gauge 8a is provided between the Bourdon pipe pressure gauge 7a and the valve 4a.

Similarly, in line 2b, Bourdon tube pressure gauge 7b
A lifting pressure gauge 8b is also provided between the valve and the valve 4b.

These lifting pressure gauges 8a and 8b measure the lifting pressure of the drainage flowing in the pipelines 2a and 2b, respectively, and receive the pressure of the water introduced from the pressure introduction section by the diaphragm, and adhere to the diaphragm. An electric signal corresponding to the pressure is obtained by the strain gauge, and the airtight and waterproof structure between the diaphragm and the cable outlet is filled with inert gas to prevent the strain gauge from deteriorating. It is configured to be.

In the pipe line 2a, between the Bourdon pipe pressure gauge 7a and the valve 5a, in this case, an electromagnetic valve 9a composed of a pilot kick type two-port valve is provided.

Similarly, in line 2b, Bourdon tube pressure gauge 7b
An electromagnetic valve 9b having the same structure is provided between the valve and the valve 5b. As is apparent from the above description, these electromagnetic valves 9 are provided by the number of pipes 2, that is, a total of 75 solenoid valves 9. Each time it is excited, it performs an opening operation and a closing operation. The relationship between the electromagnetic valves 9a and 9b and the drain holes is shown on the monitor panel 17 in FIG. The monitor panel 17 is provided to display which block of the electromagnetic valve 9 is controlled by the output of the valve control means, and whether or not the relationship between the electromagnetic valve 9 and the drain hole is provided. For clarity, reference will now be made to FIG.

As is clear from FIG. 2, 75 electromagnetic valves 9 correspond to each of the 75 drain holes, that is, one for each of the conduits 2a, 2b,. However, as is clear from FIG. 2, the 75 solenoid valves have W1 to W1.
It is divided into W14 blocks.

Accordingly, among the blocks W1 to W14, there is a difference in the number of electromagnetic valves belonging to the block depending on the block.

Here, the description returns to FIG. The water collecting pipe 3 shown in FIG. 1 is laid with an inclination in order to facilitate drainage, and the lower end faces the upper end of the drainage measuring box 10.

The drainage meter 10 and the load converter 11 constitute a load meter 12 for measuring drainage.

FIG. 3 is a side view showing the detailed configuration of the load meter 12 for measuring the displacement. As shown in FIG. 3, the drainage collected by the water collecting pipe 3 is dropped from the upper end opening of the drainage measuring box 10 and is temporarily stored. An overflow hose 10a is connected near the upper end of the drainage measuring box 10. Thus, when the amount of water stored in the drainage measuring box 10 exceeds a predetermined value, the water is drained from the overflow hose 10a.

The bottom surface of the drainage measuring box 10 is connected to a drainage pipe 10c via an electromagnetic valve 10b. The electromagnetic valve 10b opens or closes the bottom of the drainage measuring box 10 based on the control of the valve control means at the time of drainage.

The drainage pipe 10c is inserted into an annular or notched annular steady rest 13 so as to suppress a large horizontal swing at the time of installation or at the time of an earthquake.

One end of the steady rest 13 is fixed to a vertical portion of the L-shaped bracket 14. The horizontal part of the L-shaped bracket 14 is the bottom part 15a of the structural body 15.
Is fixed via anchor bolts or the like.

A vertical portion of a mounting base 16 formed in an inverted “L” shape is fixed to an upper side surface of the structure 15 via an anchor bolt or the like.

A base end of a cantilever 11a as a strain body of the load converter 11 is fixed to a horizontal portion of the mounting base 16 by a bolt or the like. This load converter 11 uses a parallelogram beam type load converter, and the tip of the cantilever 11a includes:
An eye nut 11b formed in an annular shape is fixed.

The eye nut 11b has an eyebolt 10d provided at the top of the drainage measuring box 10 and having a part of a ring cut away.
Is hung.

Thereby, the drainage measuring box 10 is hung from the tip of the cantilever 11a via the eyebolt 10d and the eye nut 11b, and distorts (bends) the cantilever 11a in accordance with the weight of the drainage stored in the drainage measuring box 10. Is caused to occur.

Although not shown, two through holes penetrating from one side to the other side and a slit communicating the through holes are formed in an intermediate portion of the cantilever 11a. And strain gauges are attached to the lower surface, respectively. A bellows 11c is attached so as to surround the circumference of the cantilever 11a to which the strain gauge is attached so as to prevent oxidation of the strain gauge due to moisture and to prevent deterioration of characteristics due to a decrease in insulation resistance due to moisture absorption.

Thus, the load converter 11 outputs an electric signal corresponding to the load, based on the resistance change of the strain gauge attached to the deformable cantilever 11a, according to the weight of the water stored in the drainage measuring box 10. It has become.

The output of the load transducer 11, that is, the output of the strain gauge is sent to the control means 16 including the valve control means and the measurement control means shown in FIG. FIG. 4 is a block diagram mainly showing the control section 16 and its input section and output section.

As is clear from FIG. 4, the valve control means of the control means 16 performs drive control of the opening and closing operations of the electromagnetic valves 9a, 9b and the electromagnetic valve 10b in a predetermined order. Measurement control means, in connection with the opening and closing operation of the electromagnetic valves 9a, 9b, 10b,
Bridge power is supplied to the lifting pressure gauges 8a and 8b and the load converter 11, and the output is read.

By performing predetermined processing of these inputs, display control by the lamp of the monitor panel 17 shown in FIG.
18 to control online transmission of data by manual operation via an interface, or to allow a personal computer 19a constituting the data processing unit 19 to perform data processing, and
In response to this, the data is printed out on the printer 19b, or the XY plotter 19c is made to perform XY plotting.

Further, the recording means 20 including a storage means such as a hard disk or a floppy disk (for backup) is made to record data.

This collecting means 20 is composed of a controller, an input / output interface, a printer, etc., in addition to the above-mentioned storage means, and manages the measurement time of the pumping pressure, the drainage amount, the setting of arbitrary measurement, the processing of the seismic measurement, the data recording, and the display. It has a brain function to perform.

The operation of this embodiment thus configured will be described with reference to the flowcharts of FIGS.

In this embodiment, the measurement of the lifting pressure and the amount of drainage can be performed by three types of measurement: periodic automatic measurement, arbitrary measurement, and earthquake measurement. First, the automatic periodic measurement will be described.

In the case of scheduled automatic measurement, it starts at 9:00:00 every morning, and first, when various measurements using thermometers, pore water pressure gauges, stress gauges, and other instruments buried in the embankment are completed, the measurement of drainage is continued. Once started, the processing according to the flowchart of FIG. 5 is performed.

FIG. 5 shows a main routine in the case of periodic automatic measurement.

In FIG. 5, in the “activation” of the flowchart,
First, the start of the apparatus is started, and the process proceeds to the processing step of “remote (management building) control set” in the flowchart, is set to the remote control state, and proceeds to the processing step of “clear valve information” in the flowchart. Thereby, the valve information of all the electromagnetic valves 9a, 9b, 10b is cleared, and the process proceeds to the processing step of "clear valve non-response information" in the flowchart.

In this processing step, if there is non-response information of each electromagnetic valve, it is cleared, the electromagnetic valve is made responsive, and the process proceeds to the "monitor panel lamp test" processing in the flowchart.

Thereby, the control means 16 tests whether or not each lamp of the monitor panel 17 shown in FIG. 2 can be turned on. If the lamp can be turned on, the control means 16 proceeds to the "non-response detected?" 9a, 9b,…, 10b and lifting pressure gauge 8a, 8
The presence or absence of a non-response portion such as b,... is determined, and if the non-response portion is detected, the process proceeds to the processing step of “abnormal display” in the flowchart, and the subsequent processes are stopped.

In this processing step, the control means 16 causes the display means 21 to display the abnormal part.

Further, in the processing step of “non-response detection?” In the flowchart, if there is no detection of a non-response portion, the process proceeds to the determination processing step of “transmission abnormal detection?” In the flowchart.

In this determination processing step, the control means 16 detects the presence or absence of an abnormality in the data transmission unit 18, and when the abnormality is detected, moves to the processing step of `` abnormality display '' in the flowchart, and the control means 16 The means 21 displays on the data transmission section 18 that there is an abnormality, and notifies the operator of the handling of the abnormality.

If the control unit 16 determines that there is no abnormality in the data transmission unit 18 in the determination process step of “transmission abnormality detection” in the flowchart, the process proceeds to the determination process step of “sequence abnormality detection?” In the flowchart.

In this determination processing step, the control means 16 determines whether there is an abnormality in the sequencer for switching the block of the timer electromagnetic valve of the sequencer (not shown).

If the result of this determination is that there is no abnormality, the flow proceeds to the determination processing step of “waiting for command” in the flowchart, and if there is an abnormality, the flow proceeds to the processing step of “display abnormality” in the same manner as described above. The control means 16
The display unit 21 is caused to display the sequencer abnormality.

Also, in the flow of the flowchart, in the determination process step of "waiting for command?"
The process returns to the "non-response detection" processing step in the flowchart, and when a command is issued, a drainage amount measurement start operation is performed, and the process proceeds to the "discharge amount block measurement" processing step in the flowchart and returns to the subroutine in FIG. The following processing is performed.

In the subroutine of FIG. 6, in the processing step of the "water drainage block measurement command" in the flowchart,
First, a command is output from the control means 16 in order to drive 75 solenoid valves belonging to the 14 blocks W1 to W14, and the flow proceeds to the processing step of “Drainage valve check?” In the flowchart. Electromagnetic valve 10b for drainage
Check the normal and defective operation of the solenoid valve 10
If b is abnormal, the process proceeds to the processing step of “abnormal display” in the flowchart. In this processing step, the control means 16 displays the abnormality of the solenoid valve 10b on the display means 21 to notify the staff.

If the electromagnetic valve 10b is normal, the process proceeds to the processing step of the “drainage command” in the flowchart,
The valve closing command is output from the control means 16 to the electromagnetic valve 10b.
The valve closing operation of 10b is performed, and the process proceeds to a determination process step of “valve non-response determination?” In the flowchart.

In this determination processing step, when the control means 16 determines that the electromagnetic valve 10b is not closed, in a processing step of "abnormal display" in the flowchart, the control means 16 displays on the display means 21 that the electromagnetic valve 10b is closed. Display that the command is not responding.

Further, in the determination process step of “valve non-response determination” in the flowchart, when the control unit 16 determines that the electromagnetic valve 10b is normal,
Move on to the processing step. In this processing step, since the electromagnetic valve 10b is normally closed, each of the blocks W1 to W14 from the 75 drain pipes 1 to the 75 water pipes 2 and the 14 water collecting pipes 3 passes. The drainage from the drain hole of the block is stored in the drainage measuring box 10, and a load corresponding to the stored amount is applied to the load application point of the cantilever 11a of the load converter 11.

As a result, the cantilever 11a is deformed, and the strain gauge changes its resistance in accordance with the deformation and is converted into an electric signal. The electric signal is input to the control means 16 as data on the amount of drainage.

In the case of this embodiment, the displacement of the load converter 11 was measured at intervals of 30 seconds from the time when the electromagnetic valve 10b was closed.
Is output, and the measuring operation is terminated when the capacity of the measuring box 10 reaches almost 80%.

Next, in the processing step of the “measurement end command” in the flowchart, the measurement end command is output from the control unit 16, and the process proceeds to the determination processing step of “end of measurement of all blocks” in the flowchart, and the measurement of all the blocks W1 to W14 is performed. The control unit 16 determines whether or not the water storage amount of the pit 10 has reached 80%. If the measurement has not been completed, the process returns to the “drainage amount measurement” processing step in the flowchart.

Also, weighing box 1 belonging to 14 blocks of blocks W1 to W14.
When it is determined that all of the zeros have reached a weight corresponding to 80% of the capacity, the control means 16 displays the measured collective total drainage of the drain holes of all 14 blocks on the display means 21.

In measuring the drainage amount, as described above, the weight and the elapsed time are continuously measured at intervals of 30 seconds until the water stored in the drainage amount measuring box 10 becomes 80% of the drainage amount measuring box 10, and the control means 16 controls The value at the time is divided by the elapsed time, and the calculation result is stored in the storage unit in the collection unit 20 and displayed on the display unit 21.

Further, if necessary, the control means 16 may
To a personal computer 19a for data processing and printing out to a printer 19b,
The plot is made on the Y plotter 19c.

Next, the process proceeds to the processing step of “measurement end drainage valve open” in the flowchart.

In this processing step, the control means 16 controls the electromagnetic valve 10b
The water stored in the drainage measuring box 10 is drained through the electromagnetic valve 10b and the drainage pipe 10c, and the process proceeds to the “measurement command reset” processing step in the flowchart.

In this processing step, the collective drainage measurement command of the 75 drain holes in 14 blocks is reset, a series of measurements is completed, and the process returns from the subroutine of FIG. 6 to the main routine of FIG. The processing step of "individual measurement of drainage amount" in the flowchart of the figure is skipped, and the processing shifts to "measurement of odd pressure".

Therefore, the routine shifts from the flowchart of FIG. 5 to the subroutine flowchart of FIG.

In the processing step of the “lift pressure odd number measurement command” in the flowchart of FIG.
The number of lifting pressure measurement commands is output, and the flow proceeds to the processing of “odd drain hole valve closed” in the flowchart.

As a result, the control means 16 simultaneously closes the odd-numbered 38 electromagnetic valves 9 under the control of the control means 16, and proceeds to the determination processing step of "valve non-response determination" in the flowchart.

In this determination processing step, the control means 16 determines whether or not the electromagnetic valve 9 that is not closed is present in the odd-numbered 38 electromagnetic valves, and if there is the electromagnetic valve 9 that is not closed, The control means 16 causes the display means 18 to display the presence of the non-responsive electromagnetic valve 9.

When it is determined that all the 38 odd-numbered electromagnetic valves 9 are closed and there is no response, the control unit 16 notifies the monitor panel 17 that the 38 odd-numbered electromagnetic valves are being closed. The lamp corresponding to the position of the 38 electromagnetic valves is turned on and displayed.

One hour after the odd-numbered electromagnetic valve 9 closes, the measured values of the 38 odd-numbered lift pressures are taken into the control means 16.
The lifting pressure gauge 8 has ^two rated capacities of 10 kg / cm ² and 5 kg / cm ² .
I use different kinds of things.

In this case, when the 38 odd-numbered electromagnetic valves 9 are closed, the water pressure in each of the odd-numbered pipelines 2 rises, and each of the odd-numbered pressure gauges 8 provided in the odd-numbered pipelines 2.
, And the measured data is taken into the control means 16 as described above.

At this time, it is also measured by the Bourdon tube pressure gauge 7a provided in each of the odd-numbered pipelines 2, and can be visually observed.

Further, the control means 18 which has taken in the measurement data of the odd-numbered pressure gauges 8 performs data processing by the personal computer 19a of the data processing unit 19, performs printout by the printer 19b, or performs printing by the XY plotter 19c. In addition to performing plot display and the like, storage in the storage unit in the collection unit 20, and the like, the display unit 21 displays the data.

Further, measurement data can be transferred from the data transmission unit 18.

Next, in the processing step of the “lift pressure measurement end command” in the flowchart, an odd-numbered lift pressure measurement command is issued, and the “odd drain hole valve open” in the flowchart is executed.
Processing steps, and the odd-numbered 38 electromagnetic valves 9
Is opened by the control means 16, and in the processing step of “reset measurement end command” in the flowchart, the measurement command of the odd-numbered pressure gauge 8 is reset, and the lift pressure by the series of odd-numbered pressure gauges 8 is reset. After the measurement is completed, the process returns to the main routine of FIG. 5 again, and shifts to the processing step of “measurement of even pressure” in the flowchart of FIG.

This "lift pressure even number measurement" process is performed in accordance with a subroutine processing procedure shown in FIG. 9, and in the processing step of the "lift pressure even number measurement command" in the flowchart, the even-numbered 37
A command for measuring the lift pressure by the 37 even-numbered lift gauges 8 corresponding to the drain holes is issued, and the process proceeds to the processing step of “close even drain hole valve” in the flowchart.

In this processing step, the closing means of the 37 even-numbered electromagnetic valves 9 provided in the 37 pipe lines 2 communicating with the 37 even-numbered drain holes is controlled by the control means 16, and the “valve” in the flowchart is referred to as “valve”. The processing shifts to the determination processing step of “non-response determination”.

In this determination processing step, the control means 16 does not respond to the even-numbered 37 electromagnetic valves 9, that is, determines whether or not there is a valve closing operation. The control means 16 proceeds to the processing step of "abnormal display",
It indicates that there is an operation failure among the 37 electromagnetic valves 9.

Further, if all the even-numbered 37 electromagnetic valves 9 perform the valve closing operation, the water pressure in the even-numbered pipeline 2 increases, and one hour later, the pumping pressure in the even-numbered pipeline 2 is reduced. The measurement is carried out by the even-numbered 37 pressure gauges 8 and the measured data is taken into the control means 16.

The captured measurement data is displayed on the display unit 21 and stored in the recording unit in the collection unit 20,
Data processing is performed by a personal computer 19a in the data processing unit 19, and the data is printed out by a printer 19b or plotted by an XY plotter 19c.

Further, if necessary, the data transmission unit 18 transmits data.

In this way, when the measurement of the lifting pressure of the pipe line 2 communicating with the even-numbered drain hole is completed, the process proceeds to the processing step of the “lifting pressure measurement end command” in the flowchart, and the measurement termination command of the even-numbered lifting pressure is issued. Then, the processing shifts to the processing step of “opening the even-number drain hole valve” in the flowchart.

In this processing step, the control means 16 performs the valve opening control of the 37 electromagnetic valves 9 of the pipe line 2 communicating with the even-numbered drain holes, and in the processing step of the “measurement end command” in the flowchart, the measurement end command is issued. Then, a series of processes for measuring the even-numbered lifting pressure ends.

Next, among the arbitrary measurement modes,
The operation will be described with reference to FIG.

The measurement in this arbitrary mode, regardless of the scheduled observation date and time,
An operator performs observation at an arbitrary timing under an arbitrary measurement type (discharge amount or up pressure) and arbitrary measurement conditions.

In FIG. 7, "Measurement, block set, measurement hole set, and drainage amount individual measurement commands" in the flowchart are shown.
In the processing step, a desired block of the blocks W1 to W14 for measuring the amount of drainage and a drain hole belonging to the block are set, and a lamp of the monitor panel 17 corresponding to the set measurement block and the drain hole is set. Is controlled by the control means 16 and displayed on the display means 21 at the same time.

At the same time, a drainage amount individual measurement command is issued, and the “measurement block, measurement drainage valve judgment” in the flowchart is performed.
The processing shifts to the processing step.

In this processing step, the control means 16 determines the block to be measured, checks the electromagnetic valve 9 in the pipe line 2 of the block to be measured, and reads “a drainage valve, a non-drainage hole valve, Moves to an operation check abnormality? "

In this determination processing step, the control means 16
The operation of 10b is checked, the solenoid valve 9 of the non-measurement target block is checked, and the operation is checked.
As a result, if there is an operation failure, the processing shifts to the processing step of “error display” in the flowchart, and the control unit 16 causes the display unit 21 to display these abnormalities.

When the determination process of the determination process step is completed, the “non-drainage hole valve close command” in the flowchart is displayed.
Then, the closing command of the electromagnetic valve 9 of the non-measurement target block is output, and the process proceeds to the “non-measurement drain hole valve closing” processing step in the flowchart.

In this processing step, the control means 16 performs valve closing control on all the electromagnetic valves 9 belonging to the non-measurement target block by the control means 16, and the pipe line 2 of the non-measurement target block is
Prevent drainage from drain holes.

Next, the processing shifts to a determination processing step of “valve non-response determination” in the flowchart, and the control unit 16 determines whether there is a defect in the valve closing operation of the electromagnetic valve 9 provided in the pipeline 2 of the non-measurement target block. Is determined, and if there is a defective electromagnetic valve 9, the control unit 16 displays the defective electromagnetic valve 9 on the display unit 21 in the processing step of “abnormal display” in the flowchart.

If there is no defective electromagnetic valve 9, the process proceeds to the processing step of “drain rise valve close command” in the flowchart, a command to close the electromagnetic valve 10 b is issued, and the “drain rise valve close” of the flowchart is issued. Move to processing step.

In this processing step, the control means 16 closes the electromagnetic valve 10b and starts storage in the drainage measuring box 10, and the processing moves to the determination processing step of `` valve non-response determination '' in the flowchart, and the control means 16 , Solenoid valve 10b
It is determined whether there is any inconvenience in the valve closing operation.

If the result of this determination is that the electromagnetic valve 10b is not responding,
In the same manner as above, the control means 16 displays an abnormality of the electromagnetic valve 10b on the display means 21.

If there is no abnormality in the above determination result, the drainage measuring box 10 is not drained by closing the electromagnetic valve 10b, and only the electromagnetic valve 9 belonging to the block to be measured is opened. Drainage from the drain hole of the target block is collected by the water collecting pipe 3 via the pipe line 2 and the electromagnetic valve 9 of the target block, dropped into the drainage measuring box 10, and stored.

A load corresponding to this water storage amount is applied to the cantilever 11a of the load converter 11, the cantilever 11a is deformed, and the electric resistance of the strain gauge changes accordingly.An electric signal corresponding to this resistance change is sent to the control means 16. It is input as a signal of the drainage amount of the measurement target block, and the drainage amount of the drain hole in the measurement target block can be individually measured.

This measurement data is sent to the collection means 20, stored in the storage means, and displayed on the display means 21.Also, the personal computer 19a of the data processing unit 19 performs data processing and prints out the data to the printer 19b. ,
Alternatively, the data can be plotted on the XY plotter 19c.

Further, it causes the data transmission unit 18 to transmit data as necessary using a private line or a multiplex radio circuit.

Next, the process proceeds to the processing step of “measurement end command” in the flowchart, and when the measurement end command is issued, proceeds to the processing step of “open drainage valve, non-drainage hole valve” in the flowchart.

In this processing step, the control means 16 controls the electromagnetic valve 10b
The water stored in the drainage measuring box 10 is drained, and at the same time, all the electromagnetic valves 9 in the closed pipes of the non-measurement target block are opened.

Next, “Reset measurement command” in the flowchart
Then, the command for measuring the amount of drainage for each block is reset, and a series of operations for individual measurement of the amount of drainage ends.

Next, the operation in the case of performing “upload individual measurement” in the “arbitrary measurement mode” will be described with reference to the flowchart of FIG.

In the processing step of the “individual lifting pressure measurement command” in the flowchart of FIG. 10, a command of the individual lifting pressure measurement is issued, and the processing shifts in the processing step of “close individual drainage valve” in the flowchart.

First, when the control means 16 wants to measure the lift pressure of any one of the 75 drain holes, a pipe provided with the lift pressure gauge 8 communicating with the drain hole to be measured is provided. The closing control of the electromagnetic valve 9a of the line 2, for example, the line 2a, is performed, and the process proceeds to the determination process step of "all the measurement holes open?" The control means 16 determines whether or not the electromagnetic valves 9 of the communicating pipe 2, that is, the electromagnetic valves 9 other than the electromagnetic valve 9a, are controlled to open.

If the result of this determination is that there is one that is closed by an electromagnetic valve 9 other than the electromagnetic valve 9a, the processing step returns to the processing step of "close individual drain valve" in the flowchart.

If all the electromagnetic valves 9 other than the electromagnetic valve 9a have been opened, the process proceeds to the determination processing step of “valve non-response determination?” In the flowchart, and one of the electromagnetic valves 9 is inactive, that is, closed. If the valve to be valved is open, the process proceeds to the processing step of “abnormal display” in the flowchart.

In this processing step, the control means 16 displays on the display means 21 that there is an electromagnetic valve that is not closed among the electromagnetic valves 9 other than the electromagnetic valve 9a.

When all the electromagnetic valves 9 other than the electromagnetic valve 9a are opened and it is determined that there is no abnormality, the control means 16 sets
The lifting pressure of the pipeline 2a by the lifting pressure gauge 8a of 2a, that is, the pipeline
Measure the lift pressure of the drain hole communicating with 2a, and perform processing such as data processing and transmission in the same manner as in the above-described odd pressure measurement and even pressure measurement. The processing shifts to the processing step.

In this processing step, when a command to end the lifting pressure measurement is issued, the processing shifts to the processing step of “individual drain hole valve opening” in the flowchart, and the control unit 16 controls the valve opening control of the electromagnetic valve 9a of the pipeline 2a. Then, the process proceeds to the “measurement end command / reset” processing step in the flowchart.

In this processing step, the lift pressure measurement end command is reset, and a series of operations of the lift pressure individual measurement ends.

In the case of the above-mentioned arbitrary measurement, it is often performed when the uplift pressure is extremely increased or when there is a large amount of rainfall such as heavy rain.

In the case of an earthquake measurement, three days after the earthquake
Observation is automatically performed after the scheduled observation of the buried design equipment at 9:00 every day.

The priority order of the scheduled automatic measurement, optional measurement, and earthquake measurement is as follows: (1) Seismic measurement, (2) Scheduled automatic measurement, (3) Optional measurement.

As described above, according to this embodiment, the “timed automatic measurement”
, The drainage of the drain holes of the 14 blocks is controlled at every predetermined time by controlling the opening of all the electromagnetic valves 9 and measured by the load meter 12 for measuring the drainage, and then the drain holes are drained in the order of odd-numbered and even-numbered. Since the data of each measurement result was processed in real time,
The measurement of the lifting pressure and drainage can be automated, and the behavior of the embankment can be grasped quickly and accurately.
The advantage that labor can be saved is obtained.

In addition, since it is configured so that arbitrary measurement can be performed, it is extremely convenient to collect data at a specific location, such as when there is some abnormality in behavior such as extremely large change in lift pressure and drainage volume. .

In addition, in the measurement at the time of the earthquake, since the predetermined observation is started prior to all the measurement modes, it is possible to quickly respond to an emergency.

Moreover, since the odd-numbered and even-numbered electromagnetic valves 9 are alternately and simultaneously closed to measure the lifting pressure measurement in the automatic measurement on a regular basis, the pressure in the drain hole rises excessively and There is no danger of damage.

Further, the following various processes can be performed based on the measurement data of the lifting pressure and the drainage amount obtained as described above.

1) Re-output of observation record 2) Correction of record data and input of data at the time of manual measurement 3) Output of monthly observation report 4) Drawing of history chart (monthly and yearly pumping pressure, drainage volume) 5) Correlation chart (water storage) 6) Drawing of a distribution map The present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the invention. Things.

For example, in the above embodiment, the solenoid valves 9 and 10b are used to open and close the flow path of the pipe line 2 and open and close the bottom of the measuring box 10. However, an electric ball valve, an air pinch valve, and an air operated valve are used. Alternatively, a fan rotary valve or the like may be used.

In particular, when a fan rotary valve is used, valve operation failure due to adhesion of algae can be avoided, so that the fan can be used stably for a long period of time.

〔The invention's effect〕

As described above in detail, according to the present invention, it is possible to automatically measure the lifting pressure and the drainage amount among the embankment behaviors, and to concentrate the measurement data in one place in real time. In addition, it is possible to provide a lift pressure and drainage amount measurement device in a levee body behavior observation device that can accurately grasp the behavior of the levee body, take appropriate safety measures, and save labor.
