JP 2008-38394 A

  However, in the case of the construction management device described in Patent Document 1, although plan data such as construction target values are stored for each pile number, since the worker inputs the pile number at an actual construction point, the pile number is If entered incorrectly, there is a risk that construction will be performed according to the construction target value associated with a different pile number. In addition, there was no data indicating the pile position in the report created after construction, so the operator had to rely on the records of the workers.

  Therefore, the present invention prevents a human error such as an erroneous input, and can reliably read plan data associated with a pile number that matches a construction position, and can store pile position information and construction result data. It is intended to provide a construction method.

  In order to achieve the above object, a method for constructing a pile driver according to the present invention is a method for constructing a pile driver in which a plurality of piles are constructed at a plurality of construction positions by a pile driver equipped with a construction management device. The apparatus includes: storage means for storing previously planned plan data including a pile number corresponding to a plurality of piles and a construction target value of a burial depth; display means for displaying pile position information based on the plan data; A GPS receiver for acquiring the position information of the aircraft, wherein the position information acquired by the GPS receiver can be displayed on the display means. Burying according to the first construction position and the second construction position shown in advance on the ground, and selecting the pile number 1 and the pile number 2 of the plan data displayed on the display means, respectively. Construction results The position information of the data and the pile is stored, and for the construction after the third pile, the position information is calculated by the offset amount from the first and second construction positions and displayed on the display means, and the displayed information is displayed. It is characterized in that the pile number is selected and buried after selecting the plan data, and the construction result data at the time of burial is stored together with the pile number information and the pile position information.

  In addition, the stored construction result data, pile number information, and pile position information are uploaded to an external server, and the stored construction result data, pile number information, and pile position information are displayed on external display means. Preferably, a report is generated based on the stored construction result data, pile number information, and pile position information.

  According to the construction method of the pile driving machine of the present invention, an erroneous input does not occur because the pile data is linked to the pile number of the plan data based on the position information calculated by the position information acquired by the GPS receiver.

  In addition, since the construction result data can be uploaded to an external server, displayed, or created in a report, the efficiency of work can be improved, and data falsification can be prevented.

FIG. 1 is an explanatory diagram schematically showing the configuration of the entire construction management system used in the method of constructing a pile driver according to the present invention. FIG. 2 is an explanatory diagram of the construction management device mounted on the pile driver.

  The construction management device 10 is mounted on the pile driving machine 1, and includes a control device 20 and various sensors 30 for detecting a driving torque, a rotation speed, a press input, and the like of a driving device provided to be able to move up and down on a reader of the pile driving machine 1. , A communication device 40 for transmitting and receiving information to and from the data server 3 via the Internet or a direct portable communication network, a GPS receiving device 50 for obtaining position information of the pile driver 1, and arithmetically processing detection information from the sensor 30. A display 60 (FIGS. 10 and 11) that displays the actual construction data and the pile selection screen, etc., and a printer 70 that prints the actual construction data and the like.

  The control device 20 includes a CPU 21 for performing various arithmetic processes, a RAM 22 and a FLASH ROM 23 (storage means of the present invention) for storing various data and programs, and an input / output interface (I / O) 24 for receiving detection information from the sensor 30. An A / D converter (A / D) 25, a serial interface (SIO) 26 and a LAN 27 for connecting to a communication device 40 and the like are provided. Further, it has a USB interface 28 for connecting a USB memory 80 for storing construction result data and the like.

  The GPS receiver 50 is provided so that the position of the core of the pile can be detected. Further, as shown in FIG. 3, a basic program, a construction management program download program, a plan data download program, and a construction management program downloaded during the previous construction are stored in the FLASH ROM 23 in advance. These are independent programs. After the power is turned on, as shown in FIG. 4, the basic program, the construction management program download program, the plan data download program, and the construction management program are started and executed in this order.

  First, the management office 2 checks the construction site location and soil properties, etc. in advance and prepares a construction plan. The pile number and the depth, feed speed, rotation speed of the stirring head, and cement milk flow rate linked to the pile number are prepared. The plan data in which the construction target values such as are set are created and uploaded to the data server 3. The data to be uploaded include position data indicating the address of the construction site and the like, and data on the number of the pile driver to be constructed.

  Specifically, the operation of the plan data will be described with reference to FIG. When creating the plan data, the position data is input in comparison with the construction drawing. The input of the position data specifies the relative position (distance) from the origin in two-dimensional coordinates.

  First, a lattice screen as shown in FIG. 14A is displayed on the monitor of the PC of the management office 2. The grid is displayed at a pitch of 10 cm, but can be enlarged or reduced in accordance with a planned pile position such as 50 cm or 25 cm.

  Enter the pile number 1 on the screen, move the arrow cursor with the PC mouse, determine the position of the pile as the origin, click an arbitrary point with the mouse, and set the clicked point as the construction position (this Set the point as the origin (0,0).) In addition, it is also possible to input the origin position using a keyboard. Next, the construction target values such as the depth, the feed speed, the rotation speed of the stirring head, the cement milk flow rate, and the like corresponding to the pile number 1 are input, and the input of the plan data associated with the pile number 1 is completed.

  Next, the stake number 2 is input, and a screen as shown in FIG. 14B is displayed. The already entered pile number 1 is indicated by a white circle. Determine the position of the pile relative to the origin, move the cursor with the mouse, and set the clicked point as the construction position (in this case, set as (20, 20). 20 cm from the origin in the X direction, Y direction) 20 cm). Further, the construction target values such as the depth, the feed speed, the rotation speed of the stirring head, the cement milk flow rate, etc., corresponding to the pile number 2 are input, and the input of the plan data associated with the pile number 2 is completed.

  Further, the stake number 3 is input, a screen as shown in FIG. 14C is displayed, and the plan data is input by the same operation, and the operation is sequentially repeated. As a result, the plan data in which the pile numbers and various construction target values associated with the pile numbers are set is completed, and uploaded to the data server 3.

  In addition, a construction management program corresponding to the type of construction method to be implemented according to the plan data and the construction machine and setting parameter data of the construction management program are also created and uploaded to the data server 3 in the same manner. The data to be uploaded include position data indicating the address of the construction site and the like, and data on the number of the pile driver to be constructed.

  Next, when the pile driver 1 arrives at the construction site, starts the engine, and turns on the power of the construction management device 10, the execution program of the construction management program is started and executed after the execution of the basic program as described above, The construction management program corresponding to the construction site and the setting parameters of the construction management program are automatically downloaded.

  The flow of this procedure will be described with reference to FIG. In step S501, the GPS receiver 50 detects the position information of the pile driver 1. Next, the process proceeds to step S502, in which the position information obtained in step S501 is compared with the position information stored at the time of the previous construction to determine whether the position information is within a predetermined range. If it is determined that the work is within the same site, the construction will be continued from the previous work. Therefore, it is determined that the previously saved construction management program and the setting parameters and plan data of the construction management program will be used. The download program ends.

  If it is determined in step S502 that the site is different, the process proceeds to step S503, where the location information and the pile driving machine data are transmitted to the data server 3 via the communication device 40, and the corresponding construction management program and Request download of setting parameter data. It should be noted that the reason why the pile driver data is transmitted is to distinguish the case where a plurality of pile drivers exist at the same construction site. In step S504, the data server 3 checks a response to the request, and determines in step S505 whether the corresponding construction management program is stored in the data server 3. Here, when there is no corresponding construction management program in the data server 3, a message of "no program" is displayed on the display 60 (step S506). In such a case, the worker may inquire the management office or the like to upload the construction management program into the data server 3.

  If the corresponding construction management program is in the data server 3, it is downloaded and stored in the RAM 22 together with the data of the setting parameters (step S507). A data check is performed to determine whether the data has been stored normally (step S508). If the data is normal, the construction management program and setting parameters are written to the FLASH ROM 23 (step S509) (see FIG. 6).

  When the writing is completed, the construction management program transmits the successfully downloaded reception response to the data server 3 (step S510), and stores the previous operation-time position information over the current position information (step S510). S511), the construction management program download program ends.

  If it is determined in step S508 that the data is not stored normally, a data error message is displayed (step S512).

  As shown in FIG. 4, after the completion of the construction management program download program, the plan data download program is started and executed, and, similarly to the construction management program, the plan data corresponding to the position of the construction site is automatically downloaded. Is done.

  The flow of this procedure will be described with reference to FIG. In step S701, the GPS receiver 50 detects the position information of the pile driver 1. Next, the process proceeds to step S702, and it is determined whether or not site plan data corresponding to the position information obtained in step S501 is stored. If the plan data already exists, the plan data download program ends.

  If the plan data is not stored in step S702, the process proceeds to step S703, where the position information and the pile driving machine number data are transmitted to the data server 3 via the communication device 40, and the corresponding planning data Request download. It should be noted that the reason why the pile driver data is transmitted is to distinguish the case where a plurality of pile drivers exist at the same construction site. In step S704, the data server 3 checks the response to the request, and determines in step S705 whether the corresponding plan data is stored in the data server 3. Here, when there is no corresponding plan data in the data server 3, a message "No plan data" is displayed on the display 60 (step S706). In such a case as well, the operator may inquire of the management office or the like as in the construction management program.

  If the corresponding plan data exists in the data server 3, it is downloaded and stored in the RAM 22 (step S707). A data check is performed to determine whether the data has been stored normally (step S708). If the data has been stored normally, the plan data is written to the FLASH ROM 23 (step S709) (see FIG. 8).

  When the writing is completed, the reception response that the plan data has been successfully downloaded is transmitted to the data server 3 (step S710), and the position information at the time of the previous operation is overwritten on the current position information and stored (step S711). ), The plan data download program ends.

  If it is determined in step S708 that the data is not stored normally, a data error message is displayed (step S712).

  As described above, when the download of the construction management program and the plan data according to the construction site is completed, the construction management program is activated to start burying the steel pipe pile. As described above, the position information and the pile driving machine data obtained by the GPS receiver 50 are transmitted to the data server, and the appropriate planning data, the construction management program, and the construction management are performed based on the position information and the pile driving machine data. Since the setting parameters of the program can be transmitted to the construction management device, the construction management device can be set before the construction without burdening the operator.

  FIG. 9 is a flowchart illustrating an operation when burying a plurality of steel pipe piles using the construction management program. First, the pile driver 1 is moved and set to the pile center position of the first pile (pile number 1). The pile position and the pile number are indicated in advance on the ground of the construction site according to the construction drawing. After the execution of the construction management program, it is determined whether the pile is the first pile (step S901), and the GPS receiver 50 detects the position information (x0, y0) (step S902). On the display 60, a pile selection screen shown in FIG. 10 is displayed. (Step S903).

  On the pile selection screen displayed on the display 60, pile numbers and construction points set in the plan data are displayed on a lattice, and unconstructed pile numbers are displayed as white circles. It should be noted that the pile selection screen can be scrolled up, down, left, and right and enlarged and reduced so that the arrangement of the piles at the entire construction site can be confirmed.

  Touch and select the white circle indicating the stake number 1 at the coordinate position (X0, Y0) on the display (step S904). At this time, the position information (x0, y0) detected by the GPS receiver 50 is stored as the position information of the stake of the stake number 1, and is linked to the stake number.

  Next, according to the plan data, the construction target values such as the target depth of the pile number 1 are read and set (step S905), and the screen of the display 60 is switched to the construction screen shown in FIG. 11 (step S906).

  On the construction screen, the depth, speed, etc. are displayed every moment, and while making comparisons with the construction target values, various adjustments are made and the burial of steel pipe piles is advanced. When the target depth of the steel pipe pile is reached, the construction of the first pile is completed. Simultaneously with the burying construction work, the construction server transmits stake number information, construction date, construction time, time and depth, etc., to the data server 3 via the communication device 40, and the data server 3 stores the construction result data (step). S906). It should be noted that the actual construction data includes the data of the pile driving machine.

  Also, in parallel with the information transmission to the data server 3, the USB memory 80 can similarly store the data as backup data, or the printer 70 can print the construction result data.

  The embedding of the pile No. 1 is completed, and it is determined whether there is a plan for embedding the next pile in the plan data (step S907), and if there is a second or later plan, the process returns to step S901.

  In step S901, it is determined that the pile is the second pile, and the process proceeds to the next step S908, where it is determined whether the pile is the second pile. If it is determined that the pile is the second pile, the GPS receiver 50 detects the position information (x1, y1) as in the case of the first pile (step S909). Similarly, a stake selection screen shown in FIG. 10 is displayed on the display 60. (Step S910). It should be noted that the circle number of the pile number 1 has been changed to blue indicating that the construction has been completed.

  Here, the pile driver 1 is moved to the position of the pile number 2 described on the ground of the construction site, and set to the pile center position. Then, the user selects and touches the white circle of the pile number 2 on the display at the coordinate position (X1, Y1) (step S911). Similarly to the pile number 1, the pile center information (x1, y1) detected by the GPS receiver 50 is stored as the pile position information of the pile number 2 and linked to the pile number.

  Next, according to the plan data, the construction target values such as the target depth of the pile number 2 are read and set (step S912), and the screen of the display 60 is switched to the construction screen shown in FIG. 11 (step S913).

  When the construction is completed, while confirming the construction screen as in the case of the first pile, and the construction is completed, the pile number information, the pile position information, the construction date, the time, the depth and the like are transmitted to the data server 3 via the communication device 40. The construction result data is transmitted and stored (step S913).

  Furthermore, it is determined whether or not the next pile is to be buried in the plan data (step S907). The position information (x, y) detected by the device 50 is detected, and the current position (X, Y) of the pile driver 1 is calculated from the offset amount with the position information of the first and second piles using the following equation. (Step S915).

X = (x−x0) cos (α) − (y−y0) sin (α)
Y = (x−x0) sin (α) + (y−y0) cos (α)
cos (α) = [X1 · (x1-x0) + Y1 · (y1-y0)] / [(x1-x0) ² + (y1-y0) ² ]
sin (α) = [Y1 · (x1-x0) + X1 · (y1-y0)] / [(x1-x0) ² + (y1-y0) ² ]
The pile driver 1 is moved to the position of the pile number 3 described on the ground of the construction site, and set to the pile center position. The circle of the pile number corresponding to the position closest to the current position of the pile driver 1 calculated by the above equation is displayed in red on the display (step S916).

  When the red circle is touched on the pile selection screen, the construction target value according to the plan data is read together with the pile number (step S917), and the screen of the display 60 is switched to the construction screen shown in FIG. 11 (step S918).

  When the construction is completed while confirming the construction screen in the same manner as the first and second piles and the construction is completed, the pile number information, the pile position information, the construction date, the time and The construction result data such as the depth is transmitted and stored (step S913). Thereafter, the same is repeated when constructing the fourth and subsequent piles.

  As described above, since the pile number is selected based on the position information, no human error occurs due to erroneous input of the pile number or the like in the construction of the third and subsequent piles.

  The PC of the management office 2 stores a construction data monitoring program for displaying the pile position information and construction result data sent from the construction site to the data server 3 in real time. FIG. 12 is a flowchart showing the operation procedure of the construction data monitor program.

  When the construction data monitor program is started, a map within the jurisdiction of the management office 2 is displayed (step S1201). The location of the active construction machine is indicated by a circle or the like on the map. It is also possible to display a list of construction site names on another screen. If multiple pile driving machines are operating at the same construction site, it can be distinguished by the pile driving machine data.

  The construction site to be monitored is selected by clicking a circle on the map or selecting from the list (step S1202), the plan data of the construction site concerned is read, and a screen similar to the pile selection screen shown in FIG. 10 is displayed. It is displayed (step S1203).

  Similar to the pile selection screen of the construction management device 10, the pile position (construction point) is indicated by a circle, a non-constructed one is a white circle, a constructed one is a blue circle, and a constructed one is a red circle. And the pile number is indicated. When a pile number to be monitored is selected (step S1204), the screen is switched to a construction screen as shown in FIG. 11, and the state of construction can be grasped even in a remote place while displaying construction result data. It is also possible to select another pile from the construction screen (step S1206) or select another site (step S1207).

  If such a construction data monitoring program is implemented in the tablet 4, it is possible to monitor the construction from a remote place without being in the management office.

  The PC of the management office 2 stores a report creation program for creating a report based on the pile position information and construction result data sent from the construction site to the data server 3. FIG. 13 is a flowchart showing the operation procedure of the report creation program.

  When the report creation program is started, a map within the jurisdiction of the management office 2 is displayed as in the construction data monitoring program (step S1301), and a construction site for creating a report is selected (step S1302). In addition, it can also be selected from a list of construction site names.

  Based on the selected construction site, plan data, pile position information, and construction result data are read from the data server 3. When the “pile list” (step S1303), the “detailed pile data” (step S1304), and the “pile graph data processing” (step S1305) are selected, the processing proceeds to each processing screen.

  On the “Pile List” processing screen, list data such as the construction date and depth for each pile is displayed, and on the “Pile Detail Data” processing screen, it is possible to print the actual construction data for each pile number. is there. Further, on the processing screen of “graph data processing of piles”, the construction result data for each pile number can be graphed and printed. In printing the “pile list”, “pile detailed data”, and “pile graph data”, a pile arrangement diagram as shown in FIG.

  When the report creation is completed (step S1306), the construction site is changed to the report creation end state, and can be prevented from being displayed in the site selection in step S1302 from the next time.

  As described above, since it is possible to monitor at a remote place and to create construction result data at a remote place in a report, it is possible to greatly improve work efficiency and prevent data forgery and the like.

  In the above-described embodiment, the example of burying steel pipe piles is shown. However, the construction of the pile according to the present invention includes other construction methods such as ground improvement, and the type and structure of a construction machine such as a pile driver. Is also optional.

  In step S707, the plan data is downloaded from the data server 3, but a method of reading the plan data from the USB memory 80 in which the plan data is recorded can be applied. The report creation program of the PC of the management office 2 can read the position information of the pile and the execution result data recorded in the USB memory 80 and create a report.
