Description

Technical Field

[0001] This invention relates to the field of termite control technology, and in particular to a high-pressure grouting device for termite control in water conservancy projects and its chemical composition. Background Technology

[0002] Termites pose a significant threat to water conservancy projects. They nest and excavate tunnels inside water conservancy facilities such as dikes, reservoirs, and canals, severely damaging the engineering structure and causing serious accidents such as leakage and collapse. Traditional termite control methods mainly include nest excavation, pesticide spraying, and grouting. Nest excavation is inefficient and difficult to completely remove hidden termite nests. Pesticide spraying usually only works on the surface or shallow layers, making it difficult to reach deep termite nests, and may also cause environmental pollution.

[0003] While grouting can fill termite mounds to some extent, existing grouting equipment often only allows grouting from the exposed termite mound entrance or requires precise detection of the mound's location before point-to-point grouting. Termites have a wide range of activity and their mounds have complex and tortuous structures, so grouting from the entrance can easily lead to insufficient grouting. Furthermore, termite mounds are hidden, making it time-consuming and laborious to locate underground mounds. The grouting effect is limited by the accuracy of the location, making it difficult to fully and effectively cover all termite mound passages, resulting in incomplete grouting. Summary of the Invention

[0004] The technical problem to be solved by this invention is the shortcomings of existing termite control technologies for water conservancy projects, such as difficulty in positioning and low efficiency. To address this, we propose a high-pressure grouting device for termite control in water conservancy projects and its chemical composition.

[0005] To achieve the above objectives, this application adopts the following technical solution: a high-pressure grouting device for termite control in water conservancy projects and its agent composition, including grouting piles, with eight sets of pipe winding mechanisms evenly arranged along the circumference of the outer periphery of the grouting piles, and each set of pipe winding mechanisms winding up a grouting pipe.

[0006] The grouting pipe includes an outer pipe and an inner pipe. The outer pipe is coaxially sleeved on the outside of the inner pipe. Four independent grouting channels are evenly distributed circumferentially between the outer pipe and the inner pipe. Grouting ports are opened at equal intervals along the axial direction on the side wall of each grouting channel.

[0007] A flexible shaft runs coaxially through the inner tube, and a drill bit is coaxially rotatably connected to the lower end of the grouting pipe. The lower end of the flexible shaft is coaxially and fixedly connected to the upper end of the drill bit.

[0008] The grouting pile has eight vertically connected guide pipe grooves. The eight guide pipe grooves are set one by one with eight sets of pipe winding mechanisms, and the grouting pipes pass through the corresponding guide pipe grooves.

[0009] Each set of pipe winding mechanism is equipped with a corresponding grouting box above it. The upper end of the grouting pipe is rotatably sealed to the grouting box. The grouting channel is connected to the internal cavity of the grouting box. The inner pipe coaxially passes through the grouting box. A second motor is fixedly installed on the top of the grouting box. The upper end of the flexible shaft is coaxially fixedly connected to the drive shaft of the second motor.

[0010] A distributor is fixedly installed at the upper end of the grouting pile. The distributor has eight independent output channels, which are connected to eight grouting boxes respectively. A pressure pump is fixedly connected to the input end of the distributor through a flange.

[0011] The grouting piles provide an overall support frame, eight sets of pipe winding mechanisms enable orderly storage of grouting pipes, the double-pipe structure and independent grouting channels of the grouting pipes ensure stable grout delivery, the flexible shaft and drill bit work together to enable deep underground drilling of the grouting pipes, the guide pipe groove ensures the movement and guidance of the grouting pipes, the grouting box enables the grouting channels and flexible shafts to work together, and the distributor and pressure pump work together to evenly distribute the grout to each grouting pipe. The whole system achieves the function of simultaneous grouting of multiple channels without the need for precise positioning of ant holes, solving the problem of incomplete grouting of traditional equipment.

[0012] Furthermore, the pipe winding mechanism includes a support frame, which is fixedly connected to the outer periphery of the grouting pile. A first motor is fixedly installed at the bottom of the support frame, and a winding drum is rotatably connected inside the support frame. The output shaft of the first motor is coaxially and fixedly connected to one end of the winding drum, and the grouting pipe is wound onto the winding drum.

[0013] The support frame provides stable support for the winding drum. The first motor drives the winding drum to rotate in both directions, realizing the automatic winding and unwinding of the grouting pipe. This avoids the grouting pipe from becoming tangled and messy. It can release the grouting pipe synchronously with the pipe feeding mechanism during pipe feeding and can quickly store the grouting pipe after it is pulled out, improving the ease of movement of the device and the service life of the grouting pipe.

[0014] Furthermore, grouting ports are only opened in the working section where the grouting pipe extends underground; no grouting ports are opened in the non-working section where the grouting pipe is located above the ground surface.

[0015] By limiting the grouting ports to underground working sections, mortar leakage above the surface can be prevented, ensuring that all mortar is delivered to the underground ant nest area, avoiding surface pollution and mortar waste. At the same time, it ensures stable underground grouting pressure and improves the filling efficiency and density of mortar in the ant nest channel.

[0016] Furthermore, the outer peripheral wall of the flexible shaft is coated with a self-lubricating polymer wear-resistant coating.

[0017] The self-lubricating coating can significantly reduce the frictional resistance of the flexible shaft when it rotates inside the inner tube, reduce the energy loss of the second motor, ensure efficient drilling by the drill bit, enhance the wear resistance of the flexible shaft, avoid damage caused by long-term rotation and friction between the flexible shaft and the inner tube, extend the service life of the flexible shaft, and ensure long-term stable drilling operations.

[0018] Furthermore, a pipe-feeding mechanism is provided inside the grouting pile. The pipe-feeding mechanism includes a third motor, which is fixedly installed on the upper inner side of the grouting pile. The output shaft of the third motor is coaxially fixedly connected to a first reciprocating screw, and a first lifting block is connected to the first reciprocating screw through a nut.

[0019] The outer peripheral wall of the first lifting block is integrally formed with eight first sliders along the circumferential direction. The eight first sliders are set one-to-one with eight guide tube grooves. Each first slider is slidably engaged with a first friction block.

[0020] The first friction block has a first inclined groove on the side facing the first slider. The first slider slides in conjunction with the first inclined groove, and the inclined direction of the first inclined groove is adapted to the lifting direction of the first lifting block.

[0021] The third motor drives the first reciprocating screw to rotate, causing the first lifting block to move up and down reciprocally. When the first lifting block descends, the first slider slides along the first inclined groove, pushing the first friction block to clamp the grouting pipe and simultaneously driving the grouting pipe downward. When the first lifting block rises, the first slider slides in the opposite direction, causing the first friction block to release the grouting pipe, thus realizing intermittent and stable pipe delivery. Combined with the drilling force of the drill bit, this ensures that the grouting pipe penetrates to the specified depth underground as required.

[0022] Furthermore, an annular positioning magnet is provided above the first lifting block. The positioning magnet is coaxially fixedly installed on the inner wall of the grouting pile. The first friction block is made of ferromagnetic material, and the first friction block and the positioning magnet can be attracted and cooperate.

[0023] When the first lifting block rises, the positioning magnet magnetically attracts the ferromagnetic first friction block, causing the first friction block to quickly return to its initial clamping position. This prevents the first friction block from shifting due to gravity or vibration, ensuring that the first friction block can accurately fit with the grouting pipe during each pipe delivery action, guaranteeing a stable pipe delivery rhythm, and preventing pipe delivery jamming or slippage caused by misalignment of the friction block.

[0024] Furthermore, a horseshoe-shaped clamping groove is provided on the side of the first friction block facing the grouting pipe. The inner wall contour of the horseshoe-shaped clamping groove is adapted to the outer peripheral wall contour of the grouting pipe, and an anti-slip rubber pad is fixedly attached to the inner wall of the horseshoe-shaped clamping groove.

[0025] The horseshoe-shaped clamping groove is adapted to the shape of the grouting pipe, which can increase the contact area between the friction block and the grouting pipe and improve the clamping stability; the anti-slip rubber pad can further increase the friction force, prevent the grouting pipe from slipping during pipe delivery, and at the same time avoid the metal friction block from directly contacting the grouting pipe and causing wear on the outer wall, thus taking into account both the reliability of pipe delivery and the protection requirements of the grouting pipe.

[0026] Furthermore, a pipe-pulling mechanism is installed inside the grouting pile. The pipe-pulling mechanism includes a fourth motor, which is fixedly installed on the inner side of the grouting pile. The output shaft of the fourth motor is coaxially fixedly connected to a second reciprocating screw, and a second lifting block is connected to the second reciprocating screw via a nut.

[0027] The outer peripheral wall of the second lifting block is integrally formed with eight second sliders along the circumferential direction. The eight second sliders are set one-to-one with eight guide tube grooves. Each second slider is slidably engaged with a second friction block.

[0028] The second friction block has a second inclined groove on the side facing the second slider. The second slider slides in conjunction with the second inclined groove, and the inclination direction of the second inclined groove is adapted to the lifting direction of the second lifting block.

[0029] The fourth motor drives the second reciprocating screw to rotate, causing the second lifting block to move up and down reciprocally. When the second lifting block rises, the second slider slides along the second inclined groove, pushing the second friction block to clamp the grouting pipe and simultaneously pulling the grouting pipe upward. When the second lifting block falls, the second slider slides in the opposite direction, causing the second friction block to release the grouting pipe, thus realizing the automatic removal of the grouting pipe without manual force, reducing labor intensity, and avoiding bending and damage to the grouting pipe caused by manual removal.

[0030] Furthermore, a horseshoe-shaped clamping groove is provided on the side of the second friction block facing the grouting pipe. The inner wall contour of the horseshoe-shaped clamping groove is adapted to the outer peripheral wall contour of the grouting pipe, and an anti-slip rubber pad is fixedly attached to the inner wall of the horseshoe-shaped clamping groove.

[0031] The horseshoe-shaped clamping groove ensures that the second friction block fits tightly with the grouting pipe, improving the clamping stability during pipe pulling; the anti-slip rubber pad increases frictional resistance, prevents the grouting pipe from slipping during the pipe pulling process, ensures uniform pulling force, and avoids damage to the outer wall caused by direct friction between the friction block and the grouting pipe, ensuring that the grouting pipe can be reused and reducing equipment maintenance costs.

[0032] Furthermore, the present invention provides another technical solution: the agent composition used in the high-pressure grouting device for termite control in water conservancy projects includes a mortar base and an insecticidal functional component, wherein the insecticidal functional component is dispersed in the mortar base at a mass fraction of 0.05%-0.5%.

[0033] The mortar base is composed of the following components in parts by weight: 40-60 parts ordinary Portland cement, 80-120 parts medium sand, 20-30 parts water, and 0.2-0.5 parts polycarboxylate superplasticizer;

[0034] The insecticidal functional components include the following raw materials in the following mass ratio: 20%-30% high-efficiency cypermethrin, 10%-15% fipronil, 5%-10% carboxymethyl cellulose, 3%-5% silica dispersant, and the balance being ethanol.

[0035] The particle size of the pesticide composition is ≤50μm, the compressive strength after solidification is ≥15MPa, and the release period of the effective insecticidal component in the underground environment is ≥6 months.

[0036] The technical effects and advantages of this invention are as follows:

[0037] 1. This invention utilizes a matrix of eight grouting pipes for underground drilling. Because the grouting pipes are flexible and the drill bit is unguided, the eight grouting pipes penetrate underground at random angles and trajectories, greatly increasing the possibility of intersecting and penetrating underground termite mounds. With up to eight independent grouting channels and multiple grouting ports, it is possible to achieve wide-range, multi-point, and highly efficient grouting coverage of underground termite areas without the need for precise detection of termite mounds, completely solving the problems of difficult positioning and incomplete grouting in traditional methods.

[0038] 2. The various pipe winding mechanisms of this invention, in conjunction with the pipe feeding and pulling mechanisms, achieve automatic winding and precise feeding and pulling of the grouting pipe. The pipe winding mechanism ensures the orderly storage of the grouting pipe, avoiding tangling and damage; the pipe feeding mechanism works with the drill bit for rapid deep drilling; and the pipe pulling mechanism enables the automatic and stable extraction of the grouting pipe, reducing labor intensity and wear on the pipeline caused by manual operation, greatly improving work efficiency, and effectively extending the service life of the grouting pipe. The self-lubricating coating on the outer wall of the flexible shaft further reduces friction loss, ensuring the stability and longevity of drilling. Attached Figure Description

[0050] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of this application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application. It should be noted that similar reference numerals and letters in the following drawings indicate similar items; therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0051] Reference Figure 1 - Figure 9 This invention provides a high-pressure grouting device for termite control in water conservancy projects. Its main purpose is to efficiently eliminate and seal termite nests and passages in water conservancy projects. The device includes grouting piles 1, with eight sets of pipe winding mechanisms 2 evenly arranged circumferentially on the outer periphery of the grouting piles 1. Each set of pipe winding mechanisms 2 winds up a grouting pipe 3, allowing multiple grouting pipes 3 to operate simultaneously, greatly improving construction efficiency.

[0052] like Figure 9 As shown, the grouting pipe 3 adopts a unique double-layer structure, including an outer pipe 301 and an inner pipe 302. The outer pipe 301 is coaxially sleeved on the outside of the inner pipe 302. Four independent grouting channels 303 are evenly distributed circumferentially between the outer pipe 301 and the inner pipe 302 to ensure independent delivery and uniform distribution of grout. Grouting ports 304 are opened at equal intervals along the axial direction on the side wall of each grouting channel 303. These grouting ports 304 are used to discharge grout into the ground. A flexible shaft 305 is coaxially inserted in the inner pipe 302 to transmit rotational power. A drill bit 6 is coaxially rotatably connected to the lower end of the grouting pipe 3. The lower end of the flexible shaft 305 is coaxially fixedly connected to the upper end of the drill bit 6. When the flexible shaft 305 rotates, the drill bit 6 rotates accordingly to drill into the underground soil layer and guide the grouting pipe 3 into the ground.

[0053] The grouting pile 1 has eight vertically connected guide pipe grooves 9. The eight guide pipe grooves 9 are set one-to-one with eight sets of pipe winding mechanisms 2. The grouting pipes 3 pass through the corresponding guide pipe grooves 9. The guide pipe grooves 9 play a role in guiding and supporting the grouting pipes 3, ensuring their stability during insertion and extraction.

[0054] Each set of pipe winding mechanism 2 is equipped with a corresponding grouting box 4 above it. The upper end of the grouting pipe 3 is rotatably sealed to the grouting box 4 to ensure that the grout does not leak during the transmission process and allows the grouting pipe 3 to rotate relative to the grouting box 4. The grouting channel 303 is connected to the internal cavity of the grouting box 4, so that the grout can enter the grouting channel 303 from the grouting box 4. The inner tube 302 coaxially passes through the grouting box 4, so that the flexible shaft 305 can pass through the grouting box 4 and receive power. A second motor 5 is fixedly installed on the top of the grouting box 4. The upper end of the flexible shaft 305 is coaxially fixedly connected to the drive shaft of the second motor 5. The second motor 5 drives the flexible shaft 305 to rotate, thereby driving the drill bit 6 to perform drilling operations.

[0055] A distributor 7 is fixedly installed at the upper end of the grouting pile 1 to receive grout from the pressurizing pump 8 and distribute it to each grouting pipe 3. The distributor 7 has eight independent output channels, which are connected to eight grouting boxes 4 one by one, ensuring that each grouting pipe 3 can receive grout independently. The input end of the distributor 7 is fixedly connected to the pressurizing pump 8 through a flange. The pressurizing pump 8 is responsible for pressurizing and delivering the grout to the distributor 7, and then the distributor 7 distributes it to each grouting pipe 3.

[0056] In a specific embodiment, such as Figure 3 As shown, the pipe winding mechanism 2 includes a support frame 201, which is fixedly connected to the outer peripheral wall of the grouting pile 1, providing stable support for the winding mechanism. A first motor 202 is fixedly installed at the bottom of the support frame 201, and the first motor 202 is used to drive the winding action. A winding drum 203 is rotatably connected inside the support frame 201, and the grouting pipe 3 is wound onto the winding drum 203. The output shaft of the first motor 202 is coaxially fixedly connected to one end of the winding drum 203. By controlling the forward and reverse rotation of the first motor 202, the automatic winding and unwinding of the grouting pipe 3 can be realized, avoiding the tediousness of manual operation and the problem of pipe entanglement, improving work efficiency and the service life of the grouting pipe 3.

[0057] In another embodiment, in order to more accurately control the grouting range and avoid environmental pollution, the grouting port 304 is only opened in the working section of the grouting pipe 3 that extends underground, while the non-working section of the grouting pipe 3 located above the ground surface does not have the grouting port 304. This design ensures that the grout is only released in the underground area, avoiding surface overflow and waste, while concentrating the underground grouting pressure and improving the grouting effect.

[0058] In order to reduce frictional loss and extend the service life of components, in another embodiment, the outer peripheral wall of the flexible shaft 305 is coated with a self-lubricating polymer wear-resistant coating. This coating can significantly reduce the frictional resistance of the flexible shaft 305 when it rotates in the inner tube 302, reduce the energy consumption of the second motor 5, ensure that the drill bit 6 drills efficiently and stably, and effectively prevent the flexible shaft 305 from wearing due to long-term friction, thus extending its service life.

[0059] To achieve automated insertion of the grouting pipe 3 into the ground, in one embodiment of the present invention, a pipe-feeding mechanism 10 is provided inside the grouting pile 1, such as... Figure 6 As shown, the pipe delivery mechanism 10 includes a third motor 1001, which is fixedly installed on the upper inner side of the grouting pile 1. The output shaft of the third motor 1001 is coaxially fixedly connected to a first reciprocating screw 1002. A first lifting block 1003 is connected to the first reciprocating screw 1002 via a nut. The third motor 1001 drives the first lifting block 1003 to reciprocate up and down via the screw.

[0060] The outer peripheral wall of the first lifting block 1003 is integrally formed with eight first sliders 1004 along the circumferential direction. The eight first sliders 1004 are arranged in a one-to-one correspondence with eight guide tube grooves 9. Each first slider 1004 is slidably engaged with a first friction block 1005. The first friction block 1005 has a first inclined groove 1006 on the side facing the first slider 1004. The first slider 1004 is slidably engaged with the first inclined groove 1006, and the inclined direction of the first inclined groove 1006 is adapted to the lifting direction of the first lifting block 1003.

[0061] In specific operation, when the third motor 1001 drives the first lifting block 1003 to descend, the first slider 1004 slides along the first inclined groove 1006, thereby pushing the first friction block 1005 to move inward and clamp the grouting pipe 3. After the first friction block 1005 clamps the grouting pipe 3, the first lifting block 1003 continues to descend, which will drive the clamped grouting pipe 3 to move downward, realizing pipe delivery. When the first lifting block 1003 rises, the first slider 1004 slides in the opposite direction, causing the first friction block 1005 to release the grouting pipe 3. The grouting pipe 3 then no longer rises with the lifting block, thereby realizing intermittent and stable pipe delivery of the grouting pipe 3. Combined with the drilling force of the drill bit 6, it ensures that the grouting pipe 3 penetrates to the specified depth underground as required.

[0062] As a further optimization of the pipe delivery mechanism 10, in the above embodiment, an annular positioning magnet 1007 is provided above the first lifting block 1003. The positioning magnet 1007 is coaxially fixedly installed on the inner wall of the grouting pile 1. In order to cooperate with the positioning magnet 1007, the first friction block 1005 is made of ferromagnetic material, and the first friction block 1005 and the positioning magnet 1007 can be attracted and cooperate. After the first lifting block 1003 rises and the first friction block 1005 releases the grouting pipe 3, the positioning magnet 1007 can attract the first friction block 1005 through magnetic force and quickly reset it to the initial clamping position, effectively preventing the first friction block 1005 from shifting due to gravity, ensuring that the first friction block 1005 can accurately and reliably fit with the grouting pipe 3 in each pipe delivery action, and ensuring the stability and accuracy of the pipe delivery rhythm.

[0063] To improve clamping force and protect the grouting pipe 3, in the embodiment of the above-mentioned pipe delivery mechanism 10, the first friction block 1005 has a horseshoe-shaped clamping groove on the side facing the grouting pipe 3. The inner wall contour of the horseshoe-shaped clamping groove is adapted to the outer peripheral wall contour of the grouting pipe 3. In order to further increase the friction force and protect the outer wall of the grouting pipe 3, an anti-slip rubber pad is fixedly attached to the inner wall of the horseshoe-shaped clamping groove. The design of the horseshoe-shaped groove increases the contact area between the first friction block 1005 and the grouting pipe 3, improving the stability and reliability of clamping. The anti-slip rubber pad effectively prevents the grouting pipe 3 from slipping during pipe delivery, and at the same time avoids the first friction block 1005 directly contacting the grouting pipe 3 and causing pipe wall wear, thus taking into account both the reliability of pipe delivery and the protection requirements of the grouting pipe 3.

[0064] To achieve automated extraction of the grouting pipe 3, in one embodiment of the present invention, a pipe extraction mechanism 11 is provided inside the grouting pile 1, such as... Figure 7 As shown, the pipe pulling mechanism 11 includes a fourth motor 1101, which is fixedly installed on the inner side of the grouting pile 1. The output shaft of the fourth motor 1101 is coaxially fixedly connected to a second reciprocating screw 1102. A second lifting block 1103 is connected to the second reciprocating screw 1102 via a nut. The fourth motor 1101 drives the second lifting block 1103 to move up and down reciprocally via the screw.

[0065] The outer peripheral wall of the second lifting block 1103 is integrally formed with eight second sliders 1104 along the circumferential direction. The eight second sliders 1104 are arranged in a one-to-one correspondence with the eight guide tube grooves 9. Each second slider 1104 is slidably engaged with a second friction block 1105. The second friction block 1105 has a second inclined groove 1106 on the side facing the second slider 1104. The second slider 1104 is slidably engaged with the second inclined groove 1106, and the inclined direction of the second inclined groove 1106 is adapted to the lifting direction of the second lifting block 1103.

[0066] In specific operation, when the fourth motor 1101 drives the second lifting block 1103 to rise, the second slider 1104 slides along the second inclined groove 1106, thereby pushing the second friction block 1105 to move inward and clamp the grouting pipe 3. After the second friction block 1105 clamps the grouting pipe 3, the second lifting block 1103 continues to rise, which will drive the clamped grouting pipe 3 to move upward, realizing pipe pulling. When the second lifting block 1103 descends, the second slider 1104 slides in the opposite direction, causing the second friction block 1105 to release the grouting pipe 3. The grouting pipe 3 will no longer descend with the lifting block, thereby realizing intermittent automatic pipe pulling of the grouting pipe 3 without manual force, reducing labor intensity, and avoiding bending or damage to the grouting pipe 3 that may be caused by manual pipe pulling.

[0067] As a further optimization of the pipe pulling mechanism 11, the second friction block 1105 has a horseshoe-shaped clamping groove on the side facing the grouting pipe 3. The inner wall contour of the horseshoe-shaped clamping groove is adapted to the outer peripheral wall contour of the grouting pipe 3. Similar to the pipe feeding mechanism 10, an anti-slip rubber pad is fixedly attached to the inner wall of the horseshoe-shaped clamping groove. This design ensures that the second friction block 1105 and the grouting pipe 3 are tightly fitted, providing a stable clamping force. The anti-slip rubber pad further increases the friction resistance, preventing the grouting pipe 3 from slipping during the pipe pulling process, ensuring uniform pipe pulling force, and avoiding damage to the outer wall caused by direct friction between the second friction block 1105 and the grouting pipe 3. This ensures the reusability of the grouting pipe 3 and reduces the maintenance cost of the equipment.

[0068] The typical operating procedure for this device is as follows:

[0069] First, the grouting pile 1 is placed or inserted into the ground of the area to be treated. A grout tanker is connected via a pressure pump 8. Then, the second motor 5 and the third motor 1001 are started simultaneously. When the third motor 1001 starts, it drives the first lifting block 1003 to descend. During the descent of the first lifting block 1003, the first slider 1004 slides along the first inclined groove 1006. Since the first friction block 1005 is initially attracted to the inner wall of the grouting pile 1 by the positioning magnet 1007, the descent of the first lifting block 1003 causes the first slider 1004 to push the first friction block 1005 inward to contact and clamp with the grouting pipe 3.

[0070] When the horseshoe-shaped groove on the first friction block 1005 engages with the guide pipe groove 9 to clamp the grouting pipe 3, its lateral movement is restricted. As the first lifting block 1003 continues to descend, it will cause the first friction block 1005 to disengage from the positioning magnet 1007 and move downward. The high friction between the first friction block 1005 and the grouting pipe 3 will push the grouting pipe 3 downward.

[0071] When the first lifting block 1003 moves upward, the first slider 1004 slides relative to the first inclined groove 1006, causing the first friction block 1005 to move away from the grouting pipe 3, thereby reducing the friction. The first friction block 1005 automatically resets under the attraction of the positioning magnet 1007 and returns to its original position to re-attract the positioning magnet 1007, while the grouting pipe 3 will not be lifted upward.

[0072] As the first lifting block 1003 continuously rises and falls, the grouting pipe 3 is continuously sent out from the inlet pipe groove 9 and goes deeper into the ground. At the same time, the second motor 5 drives the drill bit 6 to rotate continuously through the flexible shaft 305 to drill, thereby driving the grouting pipe 3 to go deeper into the ground. Since the grouting pipe 3 itself has a certain degree of flexibility and the drill bit 6 has no specific guidance underground, the eight grouting pipes 3 will go deeper into the ground at random angles and trajectories, greatly increasing the possibility of them passing through a large number of ant nest tunnels.

[0073] When the grouting pipe 3 has reached the predetermined depth and all the grouting ports 304 are below the ground surface, the pressurized pump 8 can be started to grout. The mortar is evenly distributed to the eight grouting pipes 3 through the distributor 7 and transported downward through the grouting channel 303. Some of the grouting ports 304 may be located in the anthill tunnels, and the mortar will be directly injected into the anthill from these unobstructed grouting ports 304. Even if the grouting ports 304 of some grouting pipes 3 are blocked by soil, the mortar can still flow completely through the distributor 7 to other unobstructed grouting pipes 3 and be injected into the anthill. This method enables rapid and wide-range grouting from the underground channels of the anthill without having to find the precise location of the anthill. It avoids the problems of traditional equipment that can only grout through the anthill outlet exposed on the ground surface, which is prone to blockage and difficult to completely fill the anthill.

[0074] After the operation is completed, the pipe pulling mechanism 11 is started to automatically pull the pipe. The fourth motor 1101 drives the second lifting block 1103 to rise, and the second slider 1104 slides along the second inclined groove 1106, pushing the second friction block 1105 to clamp the grouting pipe 3 and pull it upward. When the second lifting block 1103 descends, the second friction block 1105 releases the grouting pipe 3. This process is repeated until the grouting pipe 3 is completely pulled out. The pipe winding mechanism 2 winds up the pipe in time to complete the entire operation.

[0075] In one embodiment of the present invention, the agent composition includes a mortar base and an insecticidal functional component, wherein the insecticidal functional component is dispersed in the mortar base at a mass fraction of 0.05%-0.5%.

[0076] The mortar base is composed of the following components in parts by weight: 40-60 parts ordinary Portland cement, 80-120 parts medium sand, 20-30 parts water, and 0.2-0.5 parts polycarboxylate superplasticizer;

[0077] The insecticidal functional components include the following raw materials in the following mass ratio: 20%-30% high-efficiency cypermethrin, 10%-15% fipronil, 5%-10% carboxymethyl cellulose, 3%-5% silica dispersant, and the balance being ethanol.

[0078] The particle size of the pesticide composition is ≤50μm, the compressive strength after solidification is ≥15MPa, and the release period of the effective insecticidal component in the underground environment is ≥6 months.

[0079] The preparation method of the above pharmaceutical composition includes the following steps:

[0080] 1. Preparation of insecticidal functional components: Weigh out high-efficiency cypermethrin and fipronil technical according to the above proportions, add them to anhydrous ethanol, and stir at 50℃ and 300r / min for 30min until completely dissolved; then add sodium carboxymethyl cellulose and fumed silica, heat to 60℃, and stir at 1500r / min for 60min to form a uniformly dispersed insecticidal mother liquor;

[0081] 2. Mortar base preparation: Mix ordinary silicate cement and medium sand evenly, add deionized water and polycarboxylate superplasticizer, and mix in a planetary mixer at 500 r / min for 120 s to form a mortar base with a fluidity of 180-200 mm;

[0082] 3. Composite molding: The prepared insecticidal mother liquor is slowly added dropwise to the mortar matrix, and the stirring speed is maintained at 800 r / min for 15 min. During this period, large particulate impurities are removed by filtering through a 200-mesh sieve. Finally, the mixture is ground in a colloid mill until the particle size is ≤50μm to obtain the finished drug composition.

[0083] This pesticide composition, after being randomly inserted into the ground through eight sets of grouting pipes 3 of a high-pressure grouting device for termite control in water conservancy projects, forms a wide-ranging insecticidal protective layer through multi-channel synchronous grouting. When termites come into contact with the uncured pesticide mortar or the cured concrete, the highly efficient cypermethrin quickly knocks down the termites through contact killing, while fipronil is carried back to the nest by the termites through stomach poisoning and spreads to the entire colony, achieving complete extermination of the colony. Sodium carboxymethyl cellulose attractant can increase the frequency of termite contact with the pesticide, further improving the control efficiency. Verified through actual application in water conservancy dam projects, this pesticide composition, used in conjunction with the grouting device, achieves a termite control coverage rate of ≥90%, a control effect lasting ≥1 year, saves more than 30% of the dosage compared to traditional pesticides, and reduces mortar waste and environmental pollutant emissions.

[0084] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
