Description

Technical Field

[0001] This application relates to the field of engineering foundation treatment technology, and in particular to a self-healing device for backfill soil in a trench. Background Technology

[0002] In building foundation and underground structure construction, a trench refers to the annular groove between the foundation's outer wall and the pit's sidewall. Backfilling this trench is a crucial step in construction engineering, directly impacting the stability and durability of the building foundation. Traditional trench backfilling relies primarily on heavy machinery such as road rollers and rammers for compaction. While these methods perform well in open areas, they are difficult to implement in narrow trenches or complex terrain. In recent years, microbial soil stabilization technology has gained increasing attention due to its environmental friendliness and adaptability to complex terrain, becoming a powerful supplement to traditional mechanical compaction methods.

[0003] Currently, the construction process of microbial solidified soil mostly adopts the method of soaking before backfilling, or the method of backfilling first and then using bacterial solution and cementing solution for infiltration. It is still mainly based on manual and semi-mechanized operation, which is inefficient and easily causes problems such as uneven microbial solidification, affecting the backfill quality and low utilization rate of bacterial solution.

[0004] In summary, it is of great significance to develop a specialized device that can uniformly implement microbial soil solidification technology and is suitable for fertilizer trench backfilling needs. Utility Model Content

[0005] To reduce the problem of uneven solidification of backfill soil due to uneven contact between microbial inoculum and backfill soil, which affects the backfill quality, this application provides a self-healing device for fertilizer trench backfill soil.

[0006] This application provides a self-repairing device for backfill soil in fertilizer trenches, which adopts the following technical solution: A self-healing device for backfill soil in fertilizer trenches includes: The track device has one end erected on the ground and the other end fixed to the wall. The backfill box is mounted on a track device. A horizontal partition is installed inside the backfill box, which divides the interior of the backfill box into a storage chamber and a discharge chamber. A discharge hole is provided on the partition, with the upper end of the discharge hole communicating with the storage chamber and the lower end of the discharge hole communicating with the discharge chamber. A liquid storage chamber is provided on the backfill box, and a liquid inlet is provided on the periphery of the backfill box, which communicates with the liquid storage chamber. The spraying assembly is installed on the backfill box and is used to spray bacterial solution onto the backfill soil. The grouting assembly is located on the ground below the track device and is used to inject cementing fluid into the backfill soil.

[0007] By adopting the above technical solution, the track device provides installation space for the backfill box, allowing it to slide along the length of the track device. The backfill box provides space for the backfill soil; the backfill soil in the storage chamber can fall into the discharge chamber through the discharge hole and then into the fertilizer tank through the opening at the bottom of the discharge chamber. The backfill box and track device work together to gradually backfill soil into the fertilizer tank along the wall. The spraying component can spray microbial liquid onto the backfill soil passing through the discharge chamber and disperse clumps of backfill soil, ensuring the microbial liquid fully contacts the backfill soil. The grouting component... The device can inject cementing liquid into the backfill soil, and the microbial community reacts with the cementing liquid as raw material to achieve the purpose of solidifying the backfill soil in the fertilizer trench. Through the use of the track device and the backfill box, the workers can quickly operate the self-healing equipment for fertilizer trench backfill soil to fill the fertilizer trench, reducing the workload of the workers and improving the construction efficiency. Through the use of the spraying component and the grouting component, the fertilizer trench backfill soil can be evenly sprayed with microbial liquid and cementing liquid, improving the contact effect between microbial liquid and soil, thereby improving the utilization rate of microbial liquid and cementing liquid and the solidification quality of backfill soil.

[0008] Optionally, the track device includes a mounting frame and a slide rail. One end of the mounting frame is fixed to the wall, and the other end of the mounting frame is placed on the ground. Multiple sets of mounting frames are arranged at intervals along the wall. The mounting frame is provided with mounting grooves. The two ends of the slide rail are respectively embedded in the mounting grooves of two adjacent sets of mounting frames. The slide rail is provided with sliding grooves, and the lower end of the backfill box is embedded in the sliding groove.

[0009] By adopting the above technical solution, the mounting bracket provides stable support and installation foundation for the slide rail. Multiple sets of mounting brackets are evenly distributed along the wall, allowing workers to flexibly adjust the installation length of the slide rail according to the length of the fertilizer tank. This enables the backfill box to slide smoothly along the slide rail. When the backfill box slides, it can evenly inject the backfill soil in the storage cavity into the fertilizer tank, improving the uniformity of the fertilizer tank backfill soil. This ensures that the backfill soil forms a stable structure during the subsequent curing process, thereby improving the construction quality and backfilling quality of the fertilizer tank backfill soil.

[0010] Optionally, a pulley is provided at the lower end of the backfill box, and the pulley is embedded in the groove.

[0011] By adopting the above technical solution, the pulley system allows workers to easily move the backfill box along the length of the chute for backfilling, reducing the workload of workers and improving construction efficiency.

[0012] Optional, the spraying components include: A fixed frame is fixedly installed on the periphery of the backfill box. The fixed frame is provided with a fixed cavity and a telescopic hole that connects the fixed cavity and the discharge cavity. The electric telescopic rod is horizontally installed inside the fixed cavity, with the telescopic end of the electric telescopic rod pointing towards the center of the fixed frame. Multiple sets of electric telescopic rods are installed at intervals around the vertical central axis of the fixed cavity. The spray needle is inserted into the telescopic hole; The connecting block is fixedly installed on the side of the spray needle near the electric telescopic rod. The connecting block is connected to the liquid storage chamber through a hose. A control valve is installed at the end of the hose near the liquid storage chamber. Connecting plates are fixedly installed on the telescopic end of the electric telescopic pole, and each set of connecting plates is correspondingly set with multiple sets of connecting blocks; A spring is wound around the spray needle head. One end of the spring is fixedly connected to the side of the connecting block near the spray needle head, and the other end of the spring is fixedly connected to the inner wall of the fixed cavity.

[0013] By adopting the above technical solution, the fixed frame provides installation space for the electric telescopic rod, spray nozzle, connecting block, and spring. The electric telescopic rod can drive the connecting plate to move closer to the center of the fixed frame. The movement of the connecting plate will contact the connecting block and push the connecting block and the spray nozzle to move synchronously closer to the center of the fixed frame. This allows the spray nozzle to extend into the discharge chamber through the telescopic hole on the fixed frame. The operator can open the control valve to allow the microbial liquid in the storage chamber to flow into the spray nozzle through the hose and connecting block. The spray nozzle evenly sprays the microbial liquid onto the backfill soil passing through the discharge chamber, thereby realizing the spraying of microbial liquid into the backfill soil. The purpose of uniformly spraying microbial inoculant solution onto the backfill soil is to improve the uniformity of contact between the microbial inoculant solution and the backfill soil. When the electric telescopic rod retracts, the spring setting allows the connecting block and spraying needle to return to their original position under the action of the spring force. Each set of electric telescopic rods can simultaneously drive multiple sets of connecting blocks and spraying needles to move synchronously through the connecting plate. Multiple sets of electric telescopic rods are used in conjunction to control multiple sets of spraying needles to work together. The sharp ends of multiple sets of spraying needles will break up and disperse the clumps of backfill soil falling from the discharge hole, improving the looseness and uniformity of the backfill soil, further enhancing the spraying effect of the microbial inoculant solution on the backfill soil, thereby improving the solidification effect and backfill quality of the backfill soil.

[0014] Optionally, the grouting assembly includes: A cementing solution storage box is fixedly installed on the ground and contains cementing solution. Horizontal connecting pipes are installed horizontally on the ground. One end of the horizontal connecting pipe is connected to the binder storage tank. Multiple sets of horizontal connecting pipes are connected by a connecting valve. The longitudinal connecting pipe has one end fixedly connected to the side of the transverse connecting pipe near the ground, and the other end of the longitudinal connecting pipe is inserted into the backfill soil of the fertilizer trench. Multiple sets of grouting holes are set at intervals around the longitudinal connecting pipe. A pressurizing device is fixedly installed around the cementitious liquid storage tank and is used to pressurize the cementitious liquid storage tank.

[0015] By adopting the above technical solution, the cementitious liquid storage tank provides a space for the cementitious liquid, and the pressurization device can inject high-pressure gas into the storage tank, causing the cementitious liquid to flow into the transverse connecting pipe under pressure. After the workers complete the backfilling of the fertilization trench, the longitudinal connecting pipe can be inserted into the backfill soil. Under pressure, the cementitious liquid in the transverse connecting pipe seeps out evenly through the grouting holes on the side wall of the longitudinal connecting pipe, thereby achieving the purpose of injecting cementitious liquid into the backfill soil. The connecting valve allows the workers to freely adjust the number and coverage area of ​​the transverse connecting pipes according to the length and width of the fertilization trench, which facilitates flexible control of the grouting range according to actual needs, reduces cementitious liquid waste, and lowers the construction cost of grouting operations.

[0016] Optionally, the partition may be tilted on the side closest to the storage cavity.

[0017] By adopting the above technical solution, the backfill soil in the storage chamber can smoothly slide down the slope to the discharge chamber, reducing the accumulation of backfill soil on the baffle and improving the discharge stability of the backfill soil.

[0018] Optionally, a collection trough is provided at the bottom of the backfill box.

[0019] By adopting the above technical solution, the collection tank can collect excess microbial liquid sprayed by the spray needle. When there is less backfill soil through the discharge chamber, the microbial liquid sprayed by the spray needle cannot be completely mixed with the backfill soil. Some of the microbial liquid can flow into the collection tank along the inner wall of the backfill box, reducing the probability of direct loss of the liquid, thereby reducing the waste of microbial liquid and reducing the operating cost of the fertilizer tank backfill soil self-repair equipment.

[0020] Optionally, a backfill valve is provided on the discharge port, and a control rod is provided at one end of the backfill valve, which extends to the outside of the backfill box.

[0021] By adopting the above technical solution, staff can control the backfill valve with a control rod, thereby opening and closing the discharge hole and improving the convenience of staff to control the fertilizer trench backfill soil self-repair equipment.

[0022] In summary, this utility model embodiment provides a self-repairing device for backfill soil in fertilizer trenches, which includes at least one of the following beneficial technical effects: 1. The track device provides installation space for the backfill box, allowing it to slide along the length of the track device. The backfill box provides space for the backfill soil. The backfill soil in the storage chamber can fall into the discharge chamber through the discharge hole and then into the fertilizer tank through the opening at the bottom of the discharge chamber. The backfill box and track device work together to gradually backfill soil into the fertilizer tank along the wall. The spraying component can spray microbial liquid onto the backfill soil passing through the discharge chamber and disperse clumps of backfill soil, ensuring sufficient contact between the microbial liquid and the backfill soil. The grouting component can... A cementing solution is injected into the backfill soil, and the microbial community reacts with the cementing solution as raw material to solidify the backfill soil in the fertilizer trench. The use of the track device and the backfill box together allows workers to quickly operate the self-healing equipment for fertilizer trench backfill soil to fill the fertilizer trench, reducing the workload of workers and improving construction efficiency. The use of the spraying component and the grouting component together allows the fertilizer trench backfill soil to be sprayed with microbial liquid and cementing solution evenly, improving the contact effect between microbial liquid and soil, thereby improving the utilization rate of microbial liquid and cementing solution and the solidification quality of backfill soil.

[0026] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0027] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 This application discloses a self-repairing device for backfill soil in fertilizer trenches, comprising: a track device 12, a backfill box 11, a spraying assembly 4, and a grouting assembly 5; one end of the track device 12 is mounted on the ground, and the other end is fixedly mounted on a wall; the backfill box 11 is mounted on the track device 12; a partition 13 is horizontally arranged inside the backfill box 11, dividing the interior of the backfill box 11 into a storage chamber 23 and a discharge chamber 25; and a discharge port is provided on the partition 13. The upper end of the discharge hole 24 is connected to the storage chamber 23, and the lower end of the discharge hole 24 is connected to the discharge chamber 25. A liquid storage chamber 21 is provided on the backfill box 11, and a liquid inlet hole 22 is provided on the periphery of the backfill box 11. The liquid inlet hole 22 is connected to the liquid storage chamber 21. The spraying component 4 is provided on the backfill box 11 and is used to spray bacterial liquid onto the backfill soil. The grouting component 5 is provided on the ground below the track device 12 and is used to inject cementing liquid into the backfill soil.

[0028] In this embodiment, the track device 12 provides installation space for the backfill box 11, allowing the backfill box 11 to move smoothly above the fertilizer tank along the track device 12. The storage chamber 23 provides space for the backfill soil, and the liquid storage chamber 21 provides space for the microbial liquid. The partition 13 is cylindrical, and the discharge hole 24 is cylindrical. A backfill valve 14 is provided on the discharge hole 24, and a control rod 15 is provided at one end of the backfill valve 14. The control rod 15 extends to the outside of the backfill box 11. The operator can control the opening or closing of the backfill valve 14 through the control rod 15, thereby controlling the backfill soil in the storage chamber 23 to fall into the fertilizer tank through the discharge hole 24 and the discharge chamber 25. The side of the partition 13 closest to the storage chamber 23 is inclined to facilitate the backfilling in the storage chamber 23. The soil slides smoothly down the slope into the discharge chamber 25, reducing the accumulation of backfill soil on the partition plate 13 and improving the discharge stability of the backfill soil. When the backfill soil passes through the discharge chamber 25, the spraying component 4 can spray microbial liquid onto the backfill soil passing through the discharge chamber 25. After the backfill soil sprayed with the liquid falls into the fertilizer tank, the workers inject cementing liquid into the backfill soil through the grouting component 5, so that the microbial liquid and cementing liquid react in the backfill soil and generate chemical precipitates, thereby achieving the purpose of self-repair of the fertilizer tank backfill soil. By using the spraying component 4 and the grouting component 5 together, the microbial liquid and cementing liquid can be sprayed evenly on the fertilizer tank backfill soil, improving the contact effect between the microbial liquid and the soil, thereby improving the utilization rate of the microbial liquid and cementing liquid and the solidification effect on the backfill soil.

[0029] In practical use, the staff fills the backfill soil into the storage chamber 23 of the backfill box 11, injects microbial liquid into the storage chamber 21 through the liquid inlet 22, places the backfill box 11 on the track device 12, opens the backfill valve 14, and the backfill soil slides into the discharge chamber 25 through the discharge hole 24 under the action of gravity. The spraying component 4 sprays the microbial liquid stored in the storage chamber 21 evenly onto the surface of the backfill soil. After the backfill soil carrying the microbial liquid falls into the fertilizer tank, the staff installs the grouting component 5 on the fertilizer tank and injects cementing liquid into the backfill soil in the fertilizer tank through the grouting component 5. The microbial liquid and cementing liquid react in the backfill soil and generate chemical precipitates, completing the self-repair of the fertilizer tank backfill soil.

[0030] Combination Figure 1 , Figure 2 and Figure 4In one specific embodiment, the track device 12 includes a mounting frame 121 and a slide rail 122. One end of the mounting frame 121 is fixed to the wall, and the other end of the mounting frame 121 is erected on the ground. Multiple sets of mounting frames 121 are arranged at intervals along the wall. The mounting frame 121 is provided with mounting grooves 26. The two ends of the slide rail 122 are respectively embedded in the mounting grooves 26 of two adjacent sets of mounting frames 121. The slide rail 122 is provided with sliding grooves 27, and the lower end of the backfill box 11 is embedded in the sliding grooves 27.

[0031] In this embodiment, the end of the mounting bracket 121 near the wall is fixed to the embedded part of the wall by bolts. The end of the mounting bracket 121 near the wall is horizontal, and the end of the mounting bracket 121 near the ground is inclined. Two sets of mounting grooves 26 are spaced apart on the horizontal side of the mounting bracket 121. The mounting grooves 26 are arranged in an isosceles trapezoidal shape. The lower end of the slide rail 122 is trapezoidal and matches the mounting groove 26. The upper end of the slide rail 122 is provided with a sliding groove 27, which is U-shaped. The lower end of the backfill box 11 is provided with a pulley 16, which is embedded in the sliding groove 27. Inside, the backfill box 11 can move along the length of the slide rail 122 via pulleys 16. The pulleys 16 change the sliding friction between the backfill box 11 and the slide rail 122 to rolling friction, reducing the friction between the backfill box 11 and the slide rail 122. This allows workers to easily control the movement of the backfill box 11, facilitating the uniform backfilling of the fertilizer trough with the backfill soil inside the backfill box 11. Workers can set up multiple sets of mounting frames 121 according to the length of the fertilizer trough and install a corresponding number of slide rails 122, improving the adaptability of the fertilizer trough backfill soil self-healing equipment to different types of fertilizer troughs.

[0032] In practical use, the staff will fix multiple sets of mounting brackets 121 on the wall with bolts according to the length of the fertilizer tank and the on-site construction conditions, and embed slide rails 122 in two adjacent mounting slots 26. After the staff connects the slide rails 122 and the mounting brackets 121 securely, they will embed the backfill box 11 into the U-shaped slide groove 27 of the slide rail 122 through the pulley 16, so that the backfill box 11 can slide freely along the slide rail 122.

[0033] Combination Figure 1 , Figure 2 and Figure 3In one specific embodiment, the spraying assembly 4 includes: a fixed frame 41, an electric telescopic rod 42, a spraying needle 43, a connecting block 45, a connecting plate 44, and a spring 46. The fixed frame 41 is fixedly disposed around the backfill box 11. The fixed frame 41 is provided with a fixed cavity 28 and a telescopic hole 29, which connects the fixed cavity 28 and the discharge cavity 25. The electric telescopic rod 42 is horizontally disposed inside the fixed cavity 28, with the telescopic end of the electric telescopic rod 42 pointing towards the center of the fixed frame 41. Multiple sets of electric telescopic rods 42 are spaced apart around the vertical central axis of the fixed cavity 28. The nozzle 43 is inserted into the telescopic hole 29. The connecting block 45 is fixedly installed on the side of the spray nozzle 43 near the electric telescopic rod 42. The connecting block 45 is connected to the liquid storage chamber 21 through the hose 17. A control valve 18 is provided at the end of the hose 17 near the liquid storage chamber 21. The connecting plate 44 is fixedly installed on the telescopic end of the electric telescopic rod 42. Each set of connecting plates 44 is correspondingly set with multiple sets of connecting blocks 45. The spring 46 is wound around the spray nozzle 43. One end of the spring 46 is fixedly connected to the side of the connecting block 45 near the spray nozzle 43, and the other end of the spring 46 is fixedly connected to the inner wall of the fixed cavity 28.

[0034] In this embodiment, the fixing frame 41 is rectangular, with a hollow cylinder at its center. A fixing cavity 28 is provided inside the fixing frame 41. The extension of the electric telescopic rod 42 can synchronously move the connecting plate 44. The connecting plate 44 is arc-shaped, and each set of connecting plates 44 corresponds to multiple sets of connecting blocks 45. The connecting block 45 is rectangular, with one end connected to the liquid storage chamber 21 via a hose 17, and the other end connected to the spray needle 43. Operators can control the flow of microbial liquid from the liquid storage chamber 21 through the hose via the control valve 18. 17 flows into the connecting block 45 and the spray needle 43. The spray needle 43 is cylindrical, and its sharp end extends into the discharge chamber 25 through the telescopic hole 29, which is also cylindrical. When the connecting plate 44 moves towards the center of the fixed frame 41 under the push of the electric telescopic rod 42, the connecting plate 44 applies a pushing force to the connecting block 45, pushing the connecting block 45 and the spray needle 43 into the discharge chamber 25. The spring 46 is compressed by the pressure applied by the connecting block 45, and the spray needle 43 can evenly spray the microbial liquid into the backfill soil passing through the discharge chamber 25, thereby... This achieves the goal of uniformly spraying microbial inoculant solution onto the backfill soil, improving the uniformity of contact between the microbial inoculant solution and the backfill soil. When the electric telescopic rod 42 drives the connecting plate 44 to retract and reset, the elastic force of the spring 46 pushes the connecting block 45 and the spraying needle 43 to retract. Multiple sets of electric telescopic rods 42 work together to make multiple sets of spraying needles 43 repeatedly extend and retract. During the extension and retraction process, the sharp ends of the needles can break up and disperse the clumps of backfill soil falling from the discharge hole 24, improving the looseness and uniformity of the backfill soil and further enhancing the penetration effect of the microbial inoculant solution. A collection trough 3 is provided at the lower end of the backfill box 11. The collection tank 30 is arranged in a circular shape. When the amount of backfill soil passing through the discharge chamber 25 is small, the microbial liquid sprayed by the spray needle 43 cannot be completely mixed with the backfill soil. Some of the microbial liquid can flow into the collection tank 30 along the inner wall of the backfill box 11, reducing the probability of direct loss of the liquid and thus reducing the waste of microbial liquid and lowering the operating cost of the fertilizer tank backfill soil self-repair equipment. Multiple sets of spray needles are used in combination to break up and disperse the clumps of backfill soil and spray microbial liquid, enhancing the spraying effect of microbial liquid on backfill soil, thereby improving the solidification effect and backfill quality of the backfill soil.

[0035] In practical use, the operator starts the electric telescopic rod 42, which extends and moves the connecting plate 44 closer to the connecting block 45. The connecting plate 44 pushes the connecting block 45, causing the spray needle 43 to extend through the telescopic hole 29 to the center of the discharge chamber 25. At the same time, the spring 46 is compressed and deformed by the pressure of the connecting block 45. The operator opens the control valve 18, allowing the microbial liquid in the storage chamber 21 to flow into the connecting block 45 through the hose 17 and be sprayed onto the backfill soil passing through the discharge chamber 25 through the spray needle 43. The operator controls the electric telescopic rod 42 to retract, the connecting plate 44 separates from the connecting block 45, and the connecting block 45 is reset by the elastic force of the spring 46. The above operation is repeated, causing multiple sets of spray needles 43 to reciprocate and extend. The sharp ends of the spray needles 43 break up the clumps in the backfill soil during extension and retraction.

[0036] It should be noted that the electric telescopic rod 42 is electrically connected to an external power source. A PLC control panel is installed inside the fixing frame 41. The PLC control panel is electrically connected to the electric telescopic rod 42, so that the telescopic length and telescopic frequency of multiple sets of electric telescopic rods 42 can be controlled through the PLC control panel, thereby controlling the spray nozzle 43 to perform reciprocating telescopic motion.

[0037] Combination Figure 1 and Figure 4 In one specific embodiment, the grouting component 5 includes: a binder liquid storage tank 51, a horizontal connecting pipe 52, a vertical connecting pipe 53, and a pressurizing device 54; the binder liquid storage tank 51 is fixedly installed on the ground and contains binder liquid; the horizontal connecting pipe 52 is horizontally installed on the ground, one end of the horizontal connecting pipe 52 is connected to the binder liquid storage tank 51, and multiple sets of horizontal connecting pipes 52 are connected through a connecting valve 19; one end of the vertical connecting pipe 53 is fixedly connected to the side of the horizontal connecting pipe 52 near the ground, and the other end of the vertical connecting pipe 53 is inserted into the backfill soil of the fertilizer trench; multiple sets of grouting holes 31 are spaced apart around the vertical connecting pipe 53; the pressurizing device 54 is fixedly installed around the binder liquid storage tank 51 and is used to pressurize the binder liquid storage tank 51.

[0038] In this embodiment, the cementing solution storage tank 51 is rectangular in shape. The cementing solution stored in the storage tank 51 can provide reaction raw materials for microbial inoculum. The pressurizing device 54 can apply stable pressure to the inside of the cementing solution storage tank 51, causing the cementing solution to flow into the transverse connecting pipe 52. The working principle of the pressurizing device 54 is prior art in this application, so the working principle of the pressurizing device 54 will not be specifically described in this embodiment. The transverse connecting pipe 52 is cylindrical in shape. The transverse connecting pipes 52 can be connected in pairs through the connecting valve 19 to achieve the purpose of coordinated liquid supply of multiple pipe sections. Meanwhile, workers can connect an appropriate number of transverse connecting pipes 52 according to the length and width of the fertilizer tank, which improves the applicability and flexibility of the equipment. The transverse connecting pipes 52 divert the cementing liquid to multiple sets of longitudinal connecting pipes 53. The longitudinal connecting pipes 53 and the transverse connecting pipes 52 are connected by threads. The longitudinal connecting pipes 53 are cylindrical and have a sharp end at the bottom, which makes it easy to insert the longitudinal connecting pipes 53 into the backfill soil of the fertilizer tank. This allows the longitudinal connecting pipes 53 to evenly introduce the cementing liquid into the deep layer of the backfill soil of the fertilizer tank, thereby providing sufficient reaction raw materials for the microbial liquid.

[0039] In practical use, the staff connects an appropriate number of transverse connecting pipes 52 according to the length and width of the fertilizer tank. The staff fixes one end of the longitudinal connecting pipe 53 to the transverse connecting pipe 52 by threaded connection, and inserts the other end of the longitudinal connecting pipe 53 into the backfill soil of the fertilizer tank. The staff starts the pressurization device 54. Under pressure, the cementing liquid flows from the cementing liquid storage tank 51 into the longitudinal connecting pipe 53 through the transverse connecting pipe 52, and is evenly injected into the deep layer of the backfill soil through the grouting hole 31.

[0040] The implementation principle of this application is as follows: Workers load backfill soil into the storage chamber 23 of the backfill box 11. Workers inject microbial liquid into the storage chamber 21 through the inlet 22. Workers place the pulley 16 of the backfill box 11 onto the slide rail 122. Workers open the backfill valve 14, and the backfill soil slides into the discharge chamber 25 through the outlet 24 under gravity. Workers activate the electric telescopic rod 42, which extends and drives the connecting plate 44 to push the connecting block 45, causing the spray needle 43 to extend through the telescopic hole 29 to the center of the discharge chamber 25. The spring 46 is compressed by the pressure of the connecting block 45. Workers open the control valve 18, and the microbial liquid in the storage chamber 21 flows into the connecting block 45 through the hose 17 and is sprayed onto the backfill soil passing through the discharge chamber 25 through the spray needle 43. Workers control the electric telescopic rod... 42 retracts, the connecting plate 44 separates from the connecting block 45, and the connecting block 45 is reset by the elastic force of the spring 46. The above operation is repeated, so that multiple sets of spray needles 43 reciprocate and extend. When the sharp end of the spray needle 43 extends and retracts, it breaks up the clumps in the backfill soil. After the backfill soil is sprayed with microbial liquid, it enters the fertilizer tank. The staff connects an appropriate number of horizontal connecting pipes 52 and vertical connecting pipes 53 according to the length and width of the fertilizer tank, and inserts the sharp end of the vertical connecting pipe 53 into the backfill soil of the fertilizer tank. The staff starts the pressurization device 54. Under the action of pressure, the cementing liquid flows from the cementing liquid storage tank 51 into the vertical connecting pipe 53 through the horizontal connecting pipe 52, and is evenly injected into the deep layer of the backfill soil through the grouting hole 31. The microbial liquid and the cementing liquid react in the backfill soil and generate chemical precipitates, completing the self-repair of the fertilizer tank backfill soil.
