Description

  The present invention relates to a ground improvement construction support system that creates construction data for ground improvement by a ground improvement machine and supports the construction of the ground improvement and a support method thereof. More specifically, the ground improvement support system and its support can easily create appropriate construction data before performing ground excavation, cement milk injection with cement and water, and mixing with a ground improvement machine. Regarding the method.

  The ground improvement is performed to excavate the ground with a ground improvement machine and inject a ground improvement material such as cement (also referred to as ground hardening material or ground solidification material) into the excavation hole to strengthen the ground. There are various basic ground improvement methods known in the art. An example of the construction method will be described. In the ground improvement machine, first, the excavation bit at the lower end portion of the rotating rotating tube body is excavated to the deep ground. While excavating, the ground constituent object in the excavation hole is stirred with the stirring blade attached to the lower part of the rotating tube body, and the ground improvement material is ejected from the stirring blade and injected to improve the ground.

  Since the rotating tube body is a hollow body, the ground improvement material is supplied from above through the inside of the rotating tube body. The ground improvement material is supplied as cement milk made of water and cement from the upper side of the ground improvement machine via a hose or the like. In the ground improvement of a structure such as a house, columnar improvement is often performed on soft ground. This columnar shape is obtained by mixing and solidifying the ground with cement milk. Since this columnar body is the basis of a building or the like installed on the upper part, a high quality, strong and stable one is required. This ground improvement is usually performed by a ground improvement machine as described above.

The process of the columnar improvement method by this ground improvement machine is generally as shown in FIG. This ground improvement is a method of excavating the ground and injecting cement milk in which cement and water as a ground improvement material or the like are mixed and stirring and mixing with the earth and sand to improve the ground. Various proposals have been made as management devices for this ground improvement machine. For example, in a conventional ground improvement machine management device, many management items must be managed at the time of construction. However, if there are many items to be managed, there is a problem that the efficiency becomes low.
Therefore, management can be facilitated by reducing the number of management items, and it is possible to quickly and accurately determine whether good management is being performed, and also respond to changes in the strata that were not initially anticipated. A management method and a management apparatus for a ground improvement machine that can be used are well known (see, for example, Patent Documents 1 and 2). On the other hand, when injecting grout as a soil stabilizer in civil engineering foundation work, there is also known a grout injection control device that accurately controls the amount of grout injected in accordance with the approach speed of the excavating blade (for example, patents). Reference 3).

In order to maintain the quality of the pile by improving the ground, it is necessary to perform construction management as designed, and the quality of the pile is determined by the difference in the knowledge, experience, and skill of the operator operating the ground improvement machine. There is a problem that there is a risk of occurrence. In other words, it is very difficult for an operator who has little knowledge and experience and has a little skill to obtain the construction data for the ground improvement construction from the construction condition data for the ground improvement and to actually operate the ground improvement machine. This is one of the difficult tasks. For example, the calculation of the flow rate of cement milk for ground improvement and the investigation of what flow rate and speed should be used are entrusted to the worker, and the worker will immediately respond regardless of experience and skill. It cannot be considered. In addition, it takes time to create the construction data, and there is a problem that the work efficiency of the ground improvement work may be reduced, and a human error such as a calculation error may occur.
Japanese Patent No. 3437108 JP 2002-038463 A JP 54-009408 A

  However, the technology of the ground improvement machine of patent documents 1 and 2 was proposed about the management of the state at the time of construction, and the technology of patent document 3 also controls the injection amount of grout at the time of construction. Met. In other words, it did not support construction data creation performed before construction.

  Therefore, before entering the ground improvement work, the operator can simply input the construction condition data for ground improvement according to simple operations such as guidance on the display screen, and the construction data is obtained. There has been a demand for the development of construction support methods that can grasp the image of ground improvement by checking the data. For example, there has been a demand for the development of an apparatus that can automatically calculate construction data such as a required integrated flow rate value of cement milk by simply performing an input operation in accordance with guidance on the display screen. That is, if construction data can be obtained only by inputting construction condition data without requiring the operator to calculate the necessary integrated flow rate value of cement milk or the like before construction, it will be very encouraging as construction support. In addition, if construction data is obtained and output before construction, it is easy to make fine adjustments and corrections according to the construction data, and workers with slightly inferior knowledge and skills and work with little experience. Even a skilled person can make high-quality ground improvement.

  The present invention has been made to solve the conventional problems based on the above technical background, and has achieved the following object.

In FIG. 1, a leader 2 is provided on the front surface of the ground improvement machine 1, and a driving device 4 for the stirring shaft 3 is provided on the leader 2 so as to be movable in the vertical direction. This drive device 4 moves up and down by a cylinder (not shown) provided on a reader side wall.

  This drive device 4 has a rotational drive function for stirring, and rotationally drives the stirring shaft 3. Further, at the end of the agitation shaft 3, an excavation blade, a co-rotation prevention device, and an agitation head 5 composed of a plurality of agitation blades are provided from the front end side, and agitation is performed while excavating the ground. On the other hand, at the time of excavation, cement milk in which cement and water are kneaded is poured from above the stirring shaft 3 during excavation.

In relation to this, a control device 6 incorporating a ground improvement support program for supporting the ground improvement construction work is provided in the operation room 8 of the ground improvement machine 1 or in the vicinity of the operation room 8 so that the operator can It can be operated.

FIG. 11 is a block diagram showing the control device 6 incorporating the ground improvement support program. The control device 6 is provided with a CPU 30 as information processing means for performing various data processing, and a ROM 32 and a RAM 33 are connected to the CPU 30 as a main storage device via a bus 31.
The CPU 30 operates in accordance with the system program and data stored in the ROM 32 and the program and data loaded into the RAM 32 (read into the memory). As the programs loaded in the RAM 33 in this manner, the construction support program 331, the first calculation program 332, the second calculation program 333, the construction support monitor program 338, and display control for displaying characters and figures on the display means 41 are displayed. There are programs.

  The bus 31 is connected to a display means 41, an input means 42, an output means (printer) 43, a detection means (detection sensor) 44, a memory card reading / writing means 45, and the like via an interface. Further, a construction data file memory 34, a blending amount data file memory 35, etc. are connected to the bus 31.

  In the ground improvement machine 1 configured as described above, data for confirming the construction state when the necessary cement milk is injected and the ground improvement is being performed is necessary. Detection means (detection sensor) 44 is provided in the main body of the ground improvement machine 1. The means for detecting these data are well-known and frequently used, and therefore will not be described in detail. However, the object is as follows. Rotation speed detection means for detecting the rotation speed of the stirring shaft, current detection means for detecting the drive current of the stirring shaft, torque detection means for detecting torque, and cement for detecting the discharge amount of cement milk Milk flow rate detection means, depth detection means for detecting the depth of the agitation head, supply pressure detection means, feed speed (elevating speed) detection means, and the like.

  The control device 6 according to the present embodiment is a construction support system that allows an operator to create appropriate construction data by inputting input data (construction condition data) while watching the display on the construction support system display screen. The system has a program for that purpose.

  Next, the construction support system will be described. In this construction support system, key input operation can be easily performed by a response to the display contents displayed on the display means (display) 41 of the ground improvement machine 1 at the site. That is, it is possible to input construction condition data or the like by being guided by the display content of the display screen. The construction support program of this construction support system is along the flowchart shown in FIG. Next, the contents will be described along the flow of this flowchart. Before the ground improvement construction work, the ground improvement construction support system of the present embodiment is activated (S101), and the display unit 41 displays a "construction support system menu" (S102). The menu items of the construction support system of this embodiment are “columnar improvement support”, “print (depth / integrated flow rate printing function)”, and the like.

  First, when a button key which is an input means for selecting “columnar improvement support” is pressed (S103), a columnar improvement support menu is displayed (S104). The main contents of the present invention are the contents selected in this columnar improvement support menu. The content items are “cement milk flow rate calculation function”, “depth / elapsed flow rate setting”, “feed speed / instantaneous flow rate setting”, and the like. Next, when the button key of the “cement milk flow rate calculation function” is selected and pressed (S105), the display screen shown in FIG. 4 is displayed. On this screen, input for calculating the integrated flow rate value per pile.

  For this calculation, the data of construction conditions are “cement addition amount” injected into the ground, “pile diameter” of piles excavated into the ground, “improvement depth” of ground improvement and “combination ratio of cement and water ( The numerical values of the four items of “mixing amount” ”are input by the key (input means) 42 as input means (S106). The construction condition data is preferably “cement addition amount”, “pile diameter”, “improvement depth”, and “combination ratio (mixing amount)” that are often given at the site of columnar improvement work. This key 42 is of a touch key type that allows key input by touching a key portion displayed on the screen, but an operation key is provided in the vicinity of the display screen of the display means 41. Also good. An input item on the screen is selected by operating the cursor key 42b. For example, the selection is made by moving the cursor to the first to fourth input display portions 41a to 41d. After selection, numerical values are input using the numerical key 42a, the ENT key, and the like. When this input is made, the first input display part (cement addition amount display part) 41a, the second input display part (pile diameter display part) 41b, the third input display part (depth display part) adjacent to the numerical key 42a. ) 41c, the input numerical value is displayed on the fourth input display section (composition ratio display section) 41d. When the numerical values of all the items are input, the integrated flow rate value per pile is automatically calculated by the first calculation means (first calculation program) 332 of the control device 6, and the result is the fifth of the display means 41. Is displayed as an integrated flow value on the input display section (integrated flow value display section per pile) 41e (S107).

  The calculation of the integrated flow rate value per pile is performed according to the following formulas 1 and 2 (see FIG. 5).

Cement milk per 1 m ³ = (addition amount of cement / cement specific gravity) * (1 + 3.15 * composition ratio) (Formula 1)
Integrated flow rate per pile = (Pile diameter / 2) ² * π * Depth of improvement * Cement milk per 1 m ³ (Formula 2)

  For example, a numerical value “300” is displayed on the first input display unit (cement addition amount display unit) 41a, and a numerical value “600” is displayed on the second input display unit (pile diameter display unit) 41b. When a numerical value of “3.5” is input to the part (depth display part) 41c and a numerical value of “0.7” is input to the fourth input display part (composition ratio display part) 41d, it is automatically based on the formulas 1 and 2. The numerical value of “302” is displayed on the fifth input display section (integrated flow rate value display section per pile) 41e as calculated (see FIG. 4).

  Further, when the “detail” button key 42d is pressed on the display screen of FIG. 4, an example is shown in FIG. 5, and a formula for calculating the integrated flow rate per pile is displayed. Further, when the “mixing amount” button key 42e is pressed on the display screen of FIG. 5, an example is shown in FIG. 6, but the mixing ratio of the cement and water (ratio of the mixing amount) stored in the mixing amount data file 35 is shown. Detailed data is displayed. The display in FIG. 6 can be used as a reference when the operator determines an appropriate blending ratio (blending amount) in consideration of the ground conditions.

  Next, a function for printing (printing) the elapsed flow rate will be described. After inputting and setting desired data, “print” is selected from the construction support system menu (S140). A print start direction is selected (S141).

  For example, when “down” is selected in the print start direction, a screen as shown in FIG. 7 is displayed. FIG. 7 is a display screen diagram for setting conditions in the elapsed flow rate print function. From this display screen, depth data is input to the sixth input display portion 41f, and integrated flow rate data is input to the seventh input display portion 41g. In addition, when the descending side is selected, the numerical data of the improved depth has a relationship such as depth 1 <depth 2, depth 2> depth 3, depth 3 <depth 4, depth 4> depth 5, depth 5 <depth 6. Enter as follows. In addition, the numerical data of the integrated flow rate is as follows: integrated flow rate 1 <integrated flow rate 2, integrated flow rate 2 <integrated flow rate 3, integrated flow rate 3 <integrated flow rate 4, integrated flow rate 4 <integrated flow rate 5, integrated flow rate 5 <integrated flow rate 6 Input so that the relationship From this display screen, a maximum of two strokes can be input.

  For example, when the above-described data is input, for example, depth 1 = 0, integrated flow 1 = 0, depth 2 = 3.5, integrated flow 2 = 151, depth 3 = 0, integrated flow 3 = 302. As described above, data is input to each input display section of the sixth input display section 41f and each input display section of the seventh input display section 41g. This data is input using the cursor key 42b, the numeric key 42a, the ENT key, and the like. When the input data is input correctly, the setting key may be pressed. In this example, the numerical value of the same integrated flow rate is input on the descending side and the ascending side, but different numerical values may be input.

  The return key is used to return to a predetermined screen (not shown), and the “elapsed flow rate print function” is selected from this screen (S142). The following prints can be made. That is, the “cumulative flow rate per pile” calculated by the above-described first calculation means (first calculation program) 332 is set to a predetermined elapsed depth section (for example, 0.5 m in this embodiment). ) And the integrated flow rate value for each section can be printed or printed by the output means (printer) 43. If the integrated flow rate value for each section is output in advance, it is easy to compare with the detection data when the ground improvement is actually performed.

An example of the printing is shown in FIG. Fig. 8 shows the print when the cumulative flow rate per pile is divided by inputting the values of cement addition amount 300kg / m ³ , pile diameter φ600mm, improved length (improved depth) L3.5m, compounding ratio W / C0.7. An example is shown. When performing ground improvement work, it is very convenient to perform the work while looking at the numerical value on which the accumulated flow rate value at the time of passage at the depth obtained before construction is printed during excavation and lifting.

  Further, when “print pattern corresponding to depth / integrated flow rate” is selected from a screen (not shown), an operation pattern selected from the lifting / lowering operation pattern for ground improvement as shown in FIG. In addition, printing can be performed by the output means (printer) 43. This operation pattern shows a one-stroke operation confirmation pattern, and although not shown, a lifting / lowering operation pattern of 1.5 stroke, 2 stroke, etc. is also prepared. If the input data is accurate, the lifting / lowering operation pattern is selected according to the data and can be displayed or output (printed). By doing in this way, raising / lowering operation | movement can be confirmed easily as a pattern. When combined with the printing example as shown in FIG. 8, it becomes easy to grasp the image of the construction state.

  Next, the feed speed and instantaneous flow rate calculation function will be described. The feed speed and instantaneous flow rate calculation function is preferably performed after the elapsed flow rate print (print) function. “Feed speed / instantaneous flow rate setting selection function” is selected from the processing support system menu (S120). FIG. 10 shows the display screen, which is a display screen set according to the start of descent. A numerical value is input to the “improved depth” input display portion 41h and the “integrated flow rate” input display portion 41i shown on the right side of the screen by using the cursor key 42b, the numerical key 42a, the ENT key, and the like (S121). After the input, if a numerical value is input to either one of the “speed” input display section 41j or the “instantaneous flow rate” input display section 41k displayed by the numerical key 42a, the ENT key, etc. (S122), The ideal speed or instantaneous flow rate necessary to satisfy the set integrated flow rate is automatically calculated by the second calculation means (second calculation program) 333, and 1-2, 2-3, 3-4,・ ・ Displayed on (S123). In addition, although it is preferable to display the value input by the elapsed flow rate printing function on the display unit of the integrated flow rate value per pile, it may be input by a similar method.

In the second calculation means (second calculation program), the calculation is automatically performed based on Expressions 3 and 4.
Instantaneous flow rate = Speed * Integrated flow rate / Improved depth (Equation 3)
Speed = Instantaneous flow * Improved depth / Integrated flow (Formula 4)

  For example, when the improved depth is “3.5” m and the integrated flow rate is “151” L, when “1.0” is input to the “speed” input display unit 41j, automatic calculation is performed according to Equations 3 and 4. The instantaneous flow rate “43” is displayed next to the “speed” input display section 41j. On the contrary, when the improved depth is “3.5” m and the integrated flow rate is “151” L, if “43” is input to the “instantaneous flow rate” input display section 41k, automatic calculation is performed according to Equations 3 and 4. The speed “1.0” is displayed next to the “instantaneous flow rate” input display section 41k (see FIG. 10).

In this embodiment, when the cement milk flow rate calculation function, the print function (depth integrated flow rate print function), and the feed speed / instantaneous flow rate calculation function are selected in this order, the construction data is easily obtained from the construction condition data, Can be displayed and output. In other words, since construction data can be created and displayed or printed (printed or printed) before construction using the construction support system and construction support method of this form, an image of the outline of ground improvement work is shown before construction. To catch. For example, an image can be grasped by looking at data that is displayed or output (printed or printed) such as an integrated flow rate value for each section indicating the relationship between depth and integrated flow rate, an ascending / descending operation pattern, or the like. Furthermore, it is better to output (print) the display screens as shown in FIGS.
In addition, construction data and the like created using this construction support system and construction support method can be stored in the construction data memory 34.

  After displaying the construction data, outputting (printing, printing), etc. and confirming the construction data, the construction support monitor function is activated to perform ground improvement construction (S151, S152). By starting the construction support monitor function, the ground can be improved while monitoring (confirming) the data of the detection means (detection sensor) 44. In addition, it is easy to make fine adjustments and corrections during construction according to the construction data created before construction. High ground improvement can be easily performed.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to this embodiment. Needless to say, modifications can be made without departing from the scope and spirit of the present invention.
