Summary of the Invention

Problems to be Solved by the Invention

[0004] Conventionally, a plurality of injection ports of an injection pipe formed for injecting a chemical solution into soil are formed at intervals in the injection pipe. Here, if the insertion hole (hole formed by drilling) into which the injection pipe is inserted is inclined with respect to the planned value, the injection pipe will also be inclined. Then, the penetration areas of the chemical solution injected into the soil from the injection ports of adjacent injection pipes may be separated (the improvement bodies may not be continuous).

[0005] The objective of this disclosure is to prevent the penetration areas of the chemical solution injected into the soil from adjacent injection pipes from becoming separated, even when the injection pipes are tilted relative to the planned values. [Means for solving the problem]

[0006] The first embodiment of the chemical injection support device is characterized by comprising: an acquisition unit that acquires positional information of injection ports formed in injection pipes inserted into insertion holes arranged in a row in the soil; and a derivation unit that, based on the positional information acquired by the acquisition unit, derives the amount of chemical injection for each injection port so that the penetration areas of the chemical injected into the soil from the injection ports of adjacent injection pipes overlap.

[0007] According to the configuration of the first embodiment, the acquisition unit acquires positional information of the inlet formed in each of the injection pipes inserted into the insertion holes arranged in a row. Furthermore, the output unit, based on the positional information acquired by the acquisition unit, calculates the amount of chemical solution to be injected into each inlet so that the penetration areas of the chemical solution injected into the soil from adjacent inlet pipes overlap. This makes it possible to prevent the penetration areas of the chemical solution injected into the soil from adjacent inlet pipes from becoming separated, even if the injection pipes are tilted relative to the planned value.

[0008] The drug injection support device according to the second embodiment is characterized in that, in the drug injection support device described in the first embodiment, it comprises a modeling unit that models the injection pipe in three dimensions based on the position information acquired by the acquisition unit and models the penetration area of ​​the drug in three dimensions based on the amount of drug injected by the output unit, and a display unit that displays the three-dimensional model by the modeling unit on a display screen.

[0009] According to the configuration of the second embodiment, the modeling unit models the injection pipe in three dimensions based on the position information acquired by the acquisition unit, and models the penetration area of ​​the chemical solution in three dimensions based on the amount of chemical solution injected by the output unit. Furthermore, the display unit displays the three-dimensional model created by the modeling unit on the display screen. This makes it possible to visually confirm that the penetration areas of the chemical solution injected into the soil from the inlet of adjacent injection pipes overlap.

[0010] The drug injection support device according to the third embodiment is characterized in that, in the drug injection support device according to the second embodiment, the display unit displays the overlapping portion between the model of one penetration region and the model of another penetration region in a manner different from the display of other parts.

[0011] According to the configuration of the third embodiment, the display unit displays the overlapping portion between the model of one penetration region and the model of another penetration region in a manner different from the display of other parts. This makes it easy to visually confirm that the penetration regions of the drug solution overlap. [Effects of the Invention]

[0012] According to this disclosure, even when the insertion hole is tilted relative to the target value, it is possible to suppress the separation of the penetration areas of the chemical solution injected into the soil from the inlet of adjacent injection pipes.

Mode for Carrying Out the Invention

[0014] An example of the chemical solution injection support device according to an embodiment of the present disclosure will be described according to FIGS. 1 to 13. In the figures, the arrow H shown indicates the vertical direction, i.e., the up and down direction, the arrow W indicates the horizontal direction, i.e., the width direction, and the arrow D indicates the horizontal direction, i.e., the depth direction. Also, the arrow H, the arrow W, and the arrow D are orthogonal to each other.

[0015] First, a chemical solution injection method in which the chemical solution injection support device 10 according to the present embodiment is used will be described. In the chemical solution injection method described below, a process of forming one insertion hole and injecting a chemical solution into the ground G using the insertion hole will be described. In an actual chemical solution injection method, a plurality of insertion holes are formed in a row, and by injecting a chemical solution into the ground G using the plurality of insertion holes, for example, a water cutoff wall as a modified body formed by the chemical solution penetrating into the soil is formed. Here, in the present embodiment, the row shape may be one row, a plurality of rows, or a staggered pattern. That is, the row shape indicates a state of being arranged side by side from one side to the other side.

[0016] (Chemical Solution Injection Method) The following chemical solution injection method will be described separately for each process.

[0017] [Drilling Process and Grout Injection Process] First, as shown in FIG. 1(A), the ground G is drilled using a drilling device 110 to form an insertion hole 20, and a casing pipe 50 is inserted.

[0018] Also, as shown in FIG. 1(B), a grout material (not shown) is injected between the wall surface of the insertion hole 20 and the outer peripheral surface of the casing pipe 50 using a hose 12. This grout material is used to prevent the chemical solution injected into the soil through an injection port 102 described later from escaping in the vertical direction.

[0019] [Process of Inserting the Injection Pipe 100] Furthermore, as shown in FIG. 1(C), an injection pipe 100 is inserted into the casing pipe 50. A plurality of injection ports 102 (see FIG. 5(A)) that penetrate between the inside and the outside are formed at the same intervals and spaced apart in the length direction in the injection pipe 100.

[0020] Here, by inserting an insertion type inclinometer into the built-in injection pipe 100, the position information of the injection pipe 100 is detected. The details of this position information will be described later.

[0021] [Extraction process for casing pipe 50] When the position information of the injection pipe 100 is detected, the casing pipe 50 is withdrawn before the grout material has finished hardening, as shown in Figure 2(A). Then, once the grout material hardens, a thin wall formed by the grout material is created around the injection pipe 100.

[0022] [Insertion process of injection packer 150] Furthermore, as shown in Figure 2(B), the injection packer 150 is inserted into the injection tube 100. Regarding the insertion of the injection packer 150, as shown in Figure 6, all the insertion holes 20 are formed in a staggered pattern when viewed from above, and after the injection tube 100 has been inserted into all the insertion holes 20, the injection packer 150 is sequentially inserted into the injection tube 100.

[0023] As shown in Figure 5(A), the injection packer 150 is composed of an injection hose 152 with an outlet 152a formed therein and a packer material 154 that sandwiches the outlet 152a, and is a so-called double packer.

[0024] Specifically, the injection hose 152 is a flexible pipe that can be inserted into the injection pipe 100, and has a discharge port 152a formed on the peripheral wall of its tip. A pair of packing materials 154 are attached to the outer surface of the injection hose 152 so as to sandwich the discharge port 152a along the longitudinal direction of the injection hose 152.

[0025] The packer material 154 is a rubber balloon that inflates under water pressure. The outer diameter of the packer material 154 is smaller than the inner diameter of the injection pipe 100 when it is deflated. As a result, when the packer material 154 is deflated, the injection packer 150 can be moved inside the injection pipe 100, as shown in Figure 5(A).

[0026] On the other hand, the outer diameter of the packer material 154 is larger than the inner diameter of the injection pipe 100 when it is expanded. As a result, when the packer material 154 is expanded, as shown in Figure 5(B), the circumferential surface of the packer material 154 is in close contact with the inner circumferential surface of the injection pipe 100, and a space V01 is formed between the pair of packer materials 154 and the injection pipe 100.

[0027] [Medicinal solution injection process] As shown in Figure 5(C), the discharge port 152a of the injection hose 152 in the injection packer 150 inserted into the injection pipe 100 and the injection port 102 of the injection pipe 100 are positioned in the same vertical position, inflating the packer material 154. Then, the chemical solution is delivered into the injection hose 152 from a liquid delivery device (not shown). The delivered chemical solution is discharged from the discharge port 152a of the injection hose 152. Furthermore, the chemical solution discharged from the discharge port 152a fills the space V01 and is injected into the soil from the injection port 102 of the injection pipe 100. The chemical solution injected into the soil permeates the soil and forms a spherical shape, creating a chemical solution permeation region R. As will be described in detail later, the amount injected into the soil from the injection port 102 is the amount derived from the injection amount derivation unit 66 of the chemical solution injection support device 10.

[0028] As mentioned above, the injection pipe 100 has multiple injection ports 102 formed at intervals along its longitudinal direction. First, as shown in Figure 2(C), the chemical solution is injected into the soil from the injection port 102 (hereinafter sometimes referred to as "injection port 102a") formed at the lower end of the injection pipe 100, and a spherical infiltration area R is formed in the soil.

[0029] Once the injection of the chemical solution from the inlet 102a formed at the lower end of the injection pipe 100 is complete, the packer material 154 is deflated and the injection packer 150 is raised as shown in Figure 3(A). Specifically, the injection packer 150 is raised so that the inlet 102 (hereinafter sometimes referred to as "inlet 102b") formed above the inlet 102a and the discharge port 152a of the injection hose 152 (see Figure 5(B)) are positioned in the same vertical position.

[0030] Then, the packer material 154 is inflated, and the chemical solution is sent from the liquid delivery device, etc., into the injection hose 152. The sent chemical solution is discharged from the outlet 152a of the injection hose 152, as shown in Figure 5(C). Furthermore, the chemical solution discharged from the outlet 152a fills the space V01 and is injected into the soil from the injection port 102 of the injection pipe 100. The chemical solution injected into the soil permeates the soil and forms a spherical shape, and as shown in Figure 3(B), a permeation region R of the chemical solution is formed.

[0031] Once the injection of the chemical solution from the inlet 102b formed in the injection pipe 100 is complete, the packer material 154 is deflated, and the injection packer 150 is moved upward in stages, and the process described above is repeated as shown in Figures 4(A) and 4(B). As a result, the spherical penetration regions R are stacked up with some overlap.

[0032] In this way, the permeation regions R, which are stacked vertically, are formed for each of the injection pipes 100, which are arranged in a staggered pattern in a plan view, causing the permeation regions R to spread out in a wall-like manner and become an improved body.

[0033] (Configuration of the drug injection support device 10) Next, the chemical injection support device 10 will be described. The chemical injection support device 10 acquires positional information of the injection pipes 100 detected during the installation process of the injection pipes 100, and derives the amount of chemical to be injected for each injection port 102 of each injection pipe 100 so that adjacent penetration areas R in the horizontal and vertical directions overlap. First, the hardware configuration of the chemical injection support device 10 will be described.

[0034] [Hardware configuration of drug injection support device 10] As shown in Figure 7, the drug injection support device 10 includes a CPU (Central Processing Unit) 31, ROM (Read Only Memory) 32, RAM (Random Access Memory) 33, storage 34, and a communication interface (I / F) 35. Each component is connected to the others via a bus 39 so that they can communicate with each other.

[0035] The CPU 31 is a central processing unit that executes various programs and controls various parts. Specifically, the CPU 31 reads a program from the ROM 32 or storage 34 and executes the program using the RAM 33 as a working area. The CPU 31 controls each component and performs various calculations according to the program recorded in the ROM 32 or storage 34. In this embodiment, the ROM 32 or storage 34 stores a derivation program that derives the amount of chemical solution to be injected into each inlet 102 based on pre-entered soil conditions and injection pressure of the chemical solution.

[0036] ROM32 stores various programs and data. RAM33 temporarily stores programs or data as a working area. Storage34 consists of an HDD (Hard Disk Drive) or SSD (Solid State Drive) and stores various programs, including the operating system, and various data.The communication interface35 is an interface for communicating with the inclinometer inserted into the injection tube 100 and the display screen, etc., and standards such as Ethernet®, FDDI, and Wi-Fi® are used.

[0037] When executing the above derivation program, the drug injection support device 10 uses the above hardware resources to implement various functions. Next, the functional configuration implemented by the drug injection support device 10 will be described.

[0038] [Functional configuration of drug injection support device 10] As shown in Figure 8, the drug injection support device 10 includes an acquisition unit 60, a gradient deriving unit 62, a difference deriving unit 64, an injection volume deriving unit 66, a modeling unit 68, and a display unit 70. The specific functions of each unit will be explained in the operation section below.

[0039] (Operation of the drug injection support device 10) Next, the operation of the drug injection support device 10 will be explained using the flowchart shown in Figure 9.

[0040] First, in step S100, the acquisition unit 60 acquires the position information of each injection pipe 100 detected during the installation process of the injection pipes 100, and then acquires the position information of the injection port 102 formed in each injection pipe 100 from the acquired position information of the injection pipes 100.

[0041] Next, in step S200, the inclination deriving unit 62 derives the inclination angle (orientation) of the injection pipe 100 based on the position information acquired by the acquisition unit 60.

[0042] Next, in step S300, the difference derivation unit 64 compares the planned positions of the injection pipe 100 and injection port 102 with their current positions based on the inclination angle derived by the inclination derivation unit 62 and the position information acquired by the acquisition unit 60. Then, it derives the difference between the planned distance between adjacent injection ports 102 and the current distance between adjacent injection ports 102. In other words, the difference derivation unit 64 derives the portion of the distance between adjacent injection ports 102 that is close to the planned value and the portion that is farther away.

[0043] Next, in step S400, the injection amount derivation unit 66 derives the amount of chemical solution to be injected for each injection port 102 from the pre-entered soil condition, the injection pressure at which the chemical solution is injected, and the information derived by the difference derivation unit 64. Specifically, the injection amount of chemical solution is derived for each injection port 102 so that the penetration area R of the chemical solution injected into the soil by adjacent injection ports 102 overlaps. The injection amount derivation unit 66 is an example of a derivation unit.

[0044] Next, in step S500, the modeling unit 68 models the injection pipe 100 in three dimensions from the position information acquired by the acquisition unit 60, and models the penetration region R of the drug solution in a spherical shape for each injection port 102 from the injection amount information derived by the injection amount derivation unit 66.

[0045] Specifically, the modeling unit 68 models the injection tube 100 in three dimensions, as shown in Figure 10, and models the permeation area R of the drug solution as a spherical shape for each injection port 102, as shown in Figure 11.

[0046] For example, as shown in Figure 10, the second injection pipe 100 from the left in the front row of the modeled figure (hereinafter referred to as "injection pipe 100a") is tilted vertically, contrary to the planned value. As a result, the distance of injection pipe 100a to the first injection pipe 100 from the left in the front row of the modeled figure (hereinafter referred to as "injection pipe 100b") and the distance to the third injection pipe 100 from the left in the front row of the figure (hereinafter referred to as "injection pipe 100c") differs from the planned value. In other words, the distance between the injection port 102 formed on injection pipe 100a and the injection port 102 formed on injection pipe 100b differs from the planned value. Furthermore, the distance between the injection port 102 formed on injection pipe 100a and the injection port 102 formed on injection pipe 100c differs from the planned value.

[0047] In this embodiment, as shown in Figure 10, at the lower end of injection pipe 100a, the distance between injection pipe 100a and injection pipe 100b is close, while the distance between injection pipe 100a and injection pipe 100c is increased. Therefore, regarding the injection amount of the drug solution delivered by the injection amount output section 66, as shown in Figure 11, the amount of drug solution injected from the inlet 102 at the lower end of injection pipe 100b is reduced, and the amount of drug solution injected from the inlet 102 at the lower end of injection pipe 100c is increased. In other words, the penetration region R of the drug solution injected from the inlet 102 at the lower end of injection pipe 100b is reduced, and the penetration region R of the drug solution injected from the inlet 102 at the lower end of injection pipe 100c is increased.

[0048] Next, in step S600, the display unit 70 displays the data modeled by the modeling unit 68 on a display screen such as an LCD monitor, and the series of operations is completed.

[0049] (summary) Although this disclosure has described in detail specific embodiments, it will be apparent to those skilled in the art that this disclosure is not limited to such embodiments, and that various other embodiments are possible within the scope of this disclosure. Modifications, deletions, additions, and combinations of embodiments are permitted, provided they do not contradict the technical idea that can be understood by those skilled in the art from the claims, specification, and drawings.

[0050] Furthermore, although not specifically described in the above embodiment, the chemical injection support device 10 may also be equipped with a sequence adjustment unit for adjusting the order in which the chemicals are injected. When injecting chemicals into the soil from multiple injection pipes 100, if the order in which the chemicals are injected from each injection pipe 100 is adjusted, the chemicals should be injected in order from the injection pipe 100 that injects the smallest amount of chemical. Specifically, as shown in Figure 12, the distance L1 between injection pipe 100f and injection pipe 100e, and the distance L1 between injection pipe 100f and injection pipe 100g may be wider than the planned value L2. In such cases, the amount injected from injection pipe 100f needs to be increased compared to the planned value. If more chemical than the planned value is injected from injection pipe 100f, the adjacent injection port 102 may become clogged. Therefore, in such cases, the chemicals should be injected from injection pipes 100e and 100g, which inject less chemical than injection pipe 100f, and then the chemicals should be injected from injection pipe 100f.

[0051] Furthermore, a single injection tube 100 has multiple injection ports 102 spaced apart in the longitudinal direction. Therefore, when adjusting the order in which the drug solution is injected from which injection port 102, the drug solution is injected in order from the injection port 102 that injects the smallest amount of drug solution.

[0052] Specifically, as shown in Figure 13, the distance between injection tubes 100j and 100k is wider at the lower end and closer at the upper end. In such cases, the amount of chemical solution injected from the inlet at the upper end of injection tube 100k (not shown) is reduced compared to the planned value, and the amount of chemical solution injected from the inlet at the lower end of injection tube 100k (not shown) is increased compared to the planned value. If more chemical solution than the planned value is injected from the inlet at the lower end of injection tube 100k, the adjacent inlet may become clogged. Therefore, in such cases, the chemical solution is injected from the inlet at the upper end, which has a smaller injection volume compared to the planned value.

[0053] Furthermore, in the above embodiment, the chemical injection support device 10 included an acquisition unit 60, a gradient deriving unit 62, a difference deriving unit 64, an injection amount deriving unit 66, a modeling unit 68, and a display unit 70. However, the injection amount deriving unit 66 may directly derive the injection amount of chemical solution for each injection port 102 based on the soil condition, the injection pressure at which the chemical solution is injected, and the position information acquired by the acquisition unit 60, which have been pre-input.

[0054] Furthermore, although not specifically described in the above embodiment, the display unit 70 may display the overlapping portion between the model of one penetration region and the model of another penetration region on the display screen in a manner different from the display of other parts. This makes it easy to visually confirm the overlapping portion. Moreover, the display unit 70 may display the portion with the least overlapping portion on the display screen in a manner different from the display of other parts.

[0055] Furthermore, although not specifically described in the above embodiment, if the volume of the overlapping portion between the penetration region model and other penetration region models is less than a predetermined threshold, it may be displayed on the display screen differently from the other parts. This makes it easy to understand the areas requiring attention. [Explanation of Symbols]
