There are many methods for foundation treatment, including replacement cushion method, preloading drainage consolidation method, composite foundation method, chemical reinforcement method, etc. Currently, the most commonly used method for treating soft soil foundation is preloading drainage consolidation method.

[0003] Among them, the preloading drainage consolidation method often requires applying a large pressure on the soil to promote the discharge of pore water, but the process of the preloading drainage consolidation method is gradual. After the pressure is applied, the soil needs a period of time to readjust its structure. This process requires a certain amount of time for water to flow out of the pores of the soil, thereby affecting the drainage rate of the soil. Summary of the invention

[0007] Preferably, the drainage mechanism further comprises a drum screen rotatably connected to the outer wall of the buried pipe pile, an isolation drum is rotatably connected to the outer wall of the drum screen, the top of the isolation drum is fixedly connected to the bottom of the fixed plate, the top of the fixed plate is fixedly connected to an electric telescopic rod, a plurality of water inlet holes 1 are opened on the inner wall of the buried pipe pile, and a plurality of water inlet holes 2 are opened on the outer wall of the drum screen;

[0008] Among them, the bottom output end of the electric telescopic rod is fixedly connected to the top of the fixed plate, the inner wall of the fixed plate is slidably connected with a sliding rod 1, the top of the fixed plate is fixedly connected with an oil pipeline 1, the inner wall of the oil pipeline 1 is provided with hydraulic oil 1, and the top of the fixed plate is provided with an arc groove, the buried pipe piles are installed on the construction vehicle, and then the construction vehicle is started to insert the buried pipe piles into the soft soil until the fixed plate fits with the soil. After fitting, the electric telescopic rod is started to retract and drive the sliding plate to rise. When the sliding plate rises, the water inlet hole 1 of the buried pipe pile is misaligned with the water inlet hole 2 of the drum screen, so the buried pipe pile is in a closed state, and when the sliding plate rises, negative pressure will be generated at the bottom of the buried pipe pile, and as the sliding plate continues to rise, it will contact with the sliding rod 1, pushing the sliding rod 1 to rise.

[0009] Preferably, the drainage mechanism further comprises an inclined piston rod slidably connected to the inner wall of the oil delivery pipe 1, an arc-shaped piston rod slidably connected to the inner wall of the oil delivery pipe 1, a sliding block slidably connected to the inner wall of the arc-shaped groove, the bottom of the sliding block 1 is fixedly connected to the top of the drum screen, and the side walls of the sliding block 1 are fixedly connected to the side walls of the arc-shaped piston rod 1;

[0010] Among them, an arc spring 1 is fixedly connected to the side wall of the sliding block 1, and a water pump is fixedly connected to the top of the fixed plate. A water pump is connected to the output end of the side wall of the water pump. The outer wall of the water pump is slidably connected to the inner wall of the sliding plate and contacts the inclined piston rod. Since the contact surfaces of the sliding rod 1 and the inclined piston rod are both inclined surfaces, the sliding rod 1 can smoothly push the inclined piston rod to move, squeeze the hydraulic oil 1 in the oil pipeline 1, thereby pushing the arc piston rod 1 to move, driving the sliding block 1 to slide in the arc groove, squeezing the arc spring 1, and at the same time, when the sliding block 1 moves, it will also drive the drum screen to rotate, so that the water inlet hole 1 is connected with the water inlet hole 2, so that the suction force generated by the negative pressure at the bottom of the buried pipe pile will attract the water in the soil pores around the buried pipe pile, so that the water flows to the bottom of the buried pipe pile. This suction force enhances the flow of water, allows the pore water to be pumped out faster, thereby accelerating the drainage speed in the soil.

[0011] Preferably, the anti-blocking mechanism further comprises a gear rod rotatably connected to the top of the fixed cover, the outer walls of the three gear rods are meshed and connected with the side walls of the racks, the outer walls of the three racks are slidably connected with the inner wall of the sliding plate, and the tops of the three arc-shaped slides are fixedly connected with sliding rods 2;

[0012] Among them, the side walls of the three gear rods are fixedly connected with connecting rod frames, the inner walls of the three connecting rod frames are rotatably connected to the side walls of the sliding rod 2, the tops of the inner walls of the three fixed covers are fixedly connected with conical blocks, the tops of the three arc-shaped slides are slidably connected with spring blocks, and the inner walls of the three fixed covers are fixedly connected with inclined plates. The force of the sliding plates moving will squeeze the gas in the buried pipe piles when the sliding plates rise, and the squeezed gas will enter the fixed covers. At the same time, the rising of the sliding plates will drive the fixed covers to rise. When the fixed covers rise, the gear rod will mesh with the rack, so that the gear rod will rotate, driving the connecting rod frame to rotate, so that the connecting rod frame will move away from the center of the gear rod and rotate around the center of the gear rod.

[0013] Preferably, the support mechanism further comprises an arc-shaped piston rod 2 slidably connected to the inner wall of the oil delivery pipe 2, the side walls of the six arc-shaped piston rods 2 are fixedly connected to the side walls of the sliding block 2, the inner wall of the sliding plate is rotatably connected to three blocking plates, and the side walls of the three blocking plates are fixedly connected to two arc-shaped springs 2;

[0014] Among them, the side walls of the six arc springs are fixedly connected to the inner wall of the sliding plate, three fixed push rods are fixedly connected to the inner wall of the buried pipe pile, and hydraulic oil is provided on the inner walls of the six oil pipelines. The force of the arc slide moving, when the arc slide descends, will contact with the spring piston rod, squeeze the spring piston rod, and let the spring piston rod squeeze the hydraulic oil in the oil pipeline, thereby pushing the arc piston rod to move, pushing the sliding block to slide in the fixed cover, pushing the soil splashed into the fixed cover by the airflow, and letting the pushed soil fall onto the blocking plate in a concentrated manner. When the sliding plate rises, the blocking plate will be separated from the fixed push rod. Because the blocking plate was in a rotating state before, it squeezed the arc spring at the same time. When the blocking plate is separated from the fixed push rod, the rebound force of the arc spring will be released, pushing the blocking plate to reset, so that the blocking plate is in a horizontal state, so that the soil can be collected in a concentrated manner.

[0015] Preferably, the support mechanism further comprises a connecting rod fixedly connected to the bottom of the sliding plate, a spring sliding ring is slidably connected to the outer wall of the connecting rod, a fixing ring is fixedly connected to the outer wall of the connecting rod, and the top of the spring sliding ring is fixedly connected to the connecting plate;

[0016] Among them, six connecting rods are arranged at the bottom of the sliding plate, the inner walls of the connecting rods at the top are rotatably connected with the outer walls of the spring sliding ring, and the inner walls of the connecting rods at the bottom are rotatably connected with the outer walls of the fixed ring. The force of the movement of the sliding plate is utilized again, and when the sliding plate rises, the connecting rod and the spring sliding ring are also driven to rise. As the sliding plate continues to rise, the fixed rod will also contact with the connecting plate. When the connecting plate contacts the fixed rod, the fixed rod will push the connecting plate down.

[0018] Among them, three conical plug rods are slidably connected to the inner wall of the buried pipe pile, and three connecting rods 2 are rotatably connected to the outer wall of the spring sliding cylinder. The side walls of the three conical plug rods are rotatably connected to the inner wall of the connecting rod 2. Three arc-shaped sliding grooves are opened on the inner wall of the drum screen. The inner walls of the three arc-shaped sliding grooves are slidably connected to the outer wall of the conical plug rod, driving the spring sliding ring to descend, so that the connecting plate is folded, and the support block is pushed close to the inner wall of the buried pipe pile until the support block contacts the inner wall of the buried pipe pile to support the inner wall of the buried pipe pile. At the same time, the sliding plate will also contact the spring sliding cylinder, pushing the spring sliding cylinder to rise, so that the connecting rod 2 is folded, and the conical plug rod is pushed to move and inserted into the soil, thereby enhancing the stability of the buried pipe pile. By enhancing the stability of the buried pipe pile, the settlement and tilting of the buried pipe pile caused by external force or soil deformation are prevented, and the long-term stability of the buried pipe pile is maintained.

[0019] A construction method of a soft soil foundation drainage device comprises the following steps:

[0020] S1: Install the buried pipe pile on the construction vehicle, then start the construction vehicle to insert the buried pipe pile into the soft soil until the fixing plate fits with the soil. After fitting, start the electric telescopic rod to retract and drive the sliding plate to rise;

[0021] S2: When the sliding plate rises, the water inlet hole 1 of the buried pipe pile and the water inlet hole 2 of the drum screen are misaligned, so the buried pipe pile is in a closed state. When the sliding plate rises, negative pressure will be generated at the bottom of the buried pipe pile, and as the sliding plate continues to rise;

[0022] S3: It will contact with the sliding rod 1, push the sliding rod 1 up, and contact with the inclined piston rod. Since the contact surfaces of the sliding rod 1 and the inclined piston rod are both inclined surfaces, the sliding rod 1 will smoothly push the inclined piston rod to move.

[0023] The present invention has the following beneficial effects:

[0024] (1) When the present invention is used, the buried pipe pile is installed on a construction vehicle, and then the construction vehicle is started to insert the buried pipe pile into the soft soil until the fixing plate fits with the soil. After fitting, the electric telescopic rod is started to retract to drive the sliding plate to rise. When the sliding plate rises, the water inlet hole 1 of the buried pipe pile and the water inlet hole 2 of the drum screen are misaligned, so the buried pipe pile is in a closed state. When the sliding plate rises, negative pressure is generated at the bottom of the buried pipe pile. As the sliding plate continues to rise, it contacts the sliding rod 1, pushes the sliding rod 1 up, and contacts the inclined piston rod. Since the sliding rod 1 and the inclined piston rod The contact surfaces are all inclined surfaces, so the sliding rod 1 will smoothly push the inclined piston rod to move, squeeze the hydraulic oil 1 in the oil pipe 1, thereby pushing the arc-shaped piston rod 1 to move, driving the sliding block 1 to slide in the arc-shaped groove, and squeezing the arc-shaped spring 1. At the same time, when the sliding block 1 moves, it will also drive the drum screen to rotate, so that the water inlet hole 1 is connected with the water inlet hole 2, so that the suction force generated by the negative pressure at the bottom of the buried pipe pile will attract the water in the soil pores around the buried pipe pile, and make the water flow to the bottom of the buried pipe pile. This suction force enhances the flow of water, allows the pore water to be extracted faster, thereby accelerating the drainage speed in the soil.

[0025] (2) The present invention utilizes the force of the sliding plate moving. When the sliding plate rises, it will squeeze the gas in the buried pipe pile, and the squeezed gas will enter the fixed cover. At the same time, the rising of the sliding plate will drive the fixed cover to rise. When the fixed cover rises, the gear rod will mesh with the rack, causing the gear rod to rotate, driving the connecting rod frame to rotate, so that the connecting rod frame is away from the center of the gear rod and rotates around the center of the gear rod, driving the sliding rod 2 to move up and down, so that the arc-shaped slide plate moves. When the arc-shaped slide plate descends, the spring block and the conical block are separated. Because the spring block is in a squeezed state before, after separation, the rebound force of the spring block will be released, pushing the arc-shaped slide plate up. The air inlet groove at the bottom is blocked to keep the arc-shaped slide plate in a sealed state. When it descends, it can squeeze the gas entering the fixed cover again, and the second squeezed gas is guided by the inclined plate to spray out the water inlet hole 1 of the buried pipe pile, so that the soil in the water inlet hole 1 splashes into the fixed cover to clean the hole. After the water inlet hole 1 and the water inlet hole 2 are connected, the suction force generated by the negative pressure will pull the soil in the water inlet hole 2 through the cleaned water inlet hole 1, and the soil in the water inlet hole 2 of the drum screen will be sucked into the water inlet hole 1, so as to prevent the hole from being blocked and affecting the speed of water entering the buried pipe pile, so that the buried pipe pile can maintain a normal water diversion speed for a long time.

[0026] (3) The present invention utilizes the force of the arc-shaped slide plate moving. When the arc-shaped slide plate descends, it will contact the spring piston rod, squeeze the spring piston rod, and make the spring piston rod squeeze the hydraulic oil 2 in the oil delivery pipe 2, thereby pushing the arc-shaped piston rod 2 to move, pushing the sliding block 2 to slide in the fixed cover, pushing the soil splashed into the fixed cover by the airflow, and making the pushed soil fall onto the blocking plate in a concentrated manner. When the sliding plate rises, the blocking plate will be separated from the fixed push rod. Because the blocking plate is in a rotating state before, it squeezes the arc spring 2 at the same time. When the blocking plate is separated from the fixed push rod, The rebound force of the arc spring 2 will be released, pushing the blocking plate to reset and making the blocking plate horizontal, so that the soil can be collected in a centralized manner. When the sliding plate is reset, the fixed push rod will contact the blocking plate, pushing the blocking plate to rotate, allowing the soil that has fallen onto the blocking plate to slide to the bottom of the buried pipe pile and be discharged through the pumping pipe to avoid the soil from being present for too long in the fixed cover when the water inlet hole 1 is cleaned by jet, affecting the flow of gas by timely discharging the soil and reducing the risk of blockage. This ensures smooth flow of gas and maintains a good cleaning effect.

[0027] (4) The present invention again utilizes the force of the sliding plate moving. When the sliding plate rises, it will also drive the connecting rod and the spring sliding ring to rise. As the sliding plate continues to rise, the fixed rod will also contact the connecting plate. When the connecting plate contacts the fixed rod, the fixed rod will push the connecting plate down, drive the spring sliding ring down, fold the connecting plate, and push the support block close to the inner wall of the buried pipe pile until the support block contacts the inner wall of the buried pipe pile to support the inner wall of the buried pipe pile. At the same time, the sliding plate will also contact the spring sliding tube, push the spring sliding tube to rise, fold the connecting rod, and push the conical insertion rod to move and insert it into the soil, thereby enhancing the stability of the buried pipe pile. By enhancing the stability of the buried pipe pile, the settlement and tilting of the buried pipe pile caused by external force or soil deformation can be prevented, thereby maintaining the long-term stability of the buried pipe pile.

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] For example, see Figure 1 - Figure 3 The present invention is a soft soil foundation drainage device, comprising a drainage mechanism 1, wherein the drainage mechanism 1 further comprises a buried pipe pile 101, a fixed plate 102 is fixedly connected to the top of the buried pipe pile 101, and a sliding plate 103 is slidably connected to the inner wall of the buried pipe pile 101;

[0044] The anti-blocking mechanism 2 includes three fixed covers 201 fixedly connected to the top of the sliding plate 103, the inner walls of the three fixed covers 201 are all slidably connected with arc-shaped slide plates 202, and the bottom of the fixed plate 102 is fixedly connected with three racks 203;

[0045] The support mechanism 3 includes two sliding blocks 301 slidably connected to the inner wall of the fixed cover 201, two oil pipes 302 are arranged on the inner wall of the three fixed covers 201, and spring piston rods 303 are slidably connected to the inner walls of the six oil pipes 302.

[0046] The drainage mechanism 1 also includes a drum screen 104 rotatably connected to the outer wall of the buried pipe pile 101, an isolation cylinder 105 is rotatably connected to the outer wall of the drum screen 104, the top of the isolation cylinder 105 is fixedly connected to the bottom of the fixed plate 102, the top of the fixed plate 102 is fixedly connected to the electric telescopic rod 106, a plurality of water inlet holes 1 are opened on the inner wall of the buried pipe pile 101, and a plurality of water inlet holes 2 are opened on the outer wall of the drum screen 104;

[0047] The bottom output end of the electric telescopic rod 106 is fixedly connected to the top of the fixed plate 102, a sliding rod 107 is slidably connected to the inner wall of the fixed plate 102, an oil delivery pipe 108 is fixedly connected to the top of the fixed plate 102, and a hydraulic oil is provided on the inner wall of the oil delivery pipe 108. An arc groove 109 is provided on the top of the fixed plate 102. The buried pipe pile 101 is installed on the construction vehicle, and then the construction vehicle is started to insert the buried pipe pile 101 into the soft soil until the fixed plate 1 02 fits with the soil. After fitting, start the electric telescopic rod 106 to retract and drive the sliding plate 103 to rise. When the sliding plate 103 rises, the water inlet hole 1 of the buried pipe pile 101 and the water inlet hole 2 of the drum screen 104 are misaligned. Therefore, the buried pipe pile 101 is in a closed state. When the sliding plate 103 rises, negative pressure will be generated at the bottom of the buried pipe pile 101. As the sliding plate 103 continues to rise, it will contact the sliding rod 107 and push the sliding rod 107 to rise.

[0048] The drainage mechanism 1 also includes an inclined piston rod 110 slidably connected to the inner wall of the oil delivery pipe 108, an arc-shaped piston rod 111 is slidably connected to the inner wall of the oil delivery pipe 108, a sliding block 112 is slidably connected to the inner wall of the arc groove 109, the bottom of the sliding block 112 is fixedly connected to the top of the drum screen 104, and the side walls of the sliding block 112 are fixedly connected to the side walls of the arc-shaped piston rod 111;

[0049] Among them, an arc spring 113 is fixedly connected to the side wall of the sliding block 112, a water pump 114 is fixedly connected to the top of the fixed plate 102, and a water pump 115 is connected to the output end of the side wall of the water pump 114. The outer wall of the water pump 115 is slidably connected to the inner wall of the sliding plate 103 and contacts the inclined piston rod 110. Since the contact surfaces of the sliding rod 107 and the inclined piston rod 110 are both inclined surfaces, the sliding rod 107 will smoothly push the inclined piston rod 110 to move, squeezing the hydraulic oil in the oil pipe 108. Thereby, the arc piston rod 111 is pushed to move, driving the sliding block 112 to slide in the arc groove 109, squeezing the arc spring 113. At the same time, when the sliding block 112 moves, it will also drive the drum screen 104 to rotate, so that the water inlet hole 1 is connected with the water inlet hole 2, so that the suction force generated by the negative pressure at the bottom of the buried pipe pile 101 will attract the water in the soil pores around the buried pipe pile 101, and make the water flow to the bottom of the buried pipe pile 101. This suction force enhances the flow of water, allows the pore water to be drawn out faster, thereby accelerating the drainage speed in the soil.

[0050] For example 2, please refer to Figure 4 - Fig.11The present invention is a soft soil foundation drainage device. On the basis of the first embodiment, the anti-blocking mechanism 2 also includes a gear rod 204 rotatably connected to the top of the fixed cover 201, the outer walls of the three gear rods 204 are meshed with the side walls of the racks 203, the outer walls of the three racks 203 are slidably connected to the inner wall of the sliding plate 103, and the tops of the three arc-shaped slide plates 202 are fixedly connected with sliding rods 205;

[0051] The side walls of the three gear rods 204 are fixedly connected with connecting rod frames 206, the inner walls of the three connecting rod frames 206 are rotatably connected with the side walls of the sliding rod 205, the tops of the inner walls of the three fixed covers 201 are fixedly connected with conical blocks 207, the tops of the three arc-shaped slide plates 202 are slidably connected with spring blocks 208, and the inner walls of the three fixed covers 201 are fixedly connected with inclined plates 209. The force of the sliding plate 103 moving will squeeze the gas in the buried pipe pile 101 when the sliding plate 103 rises, and the squeezed gas will enter the fixed cover 201. At the same time, the rising of the sliding plate 103 will drive the fixed cover 201 to move upward. When the fixed cover 201 rises, the gear rod 204 is meshed with the rack 203, so that the gear rod 204 rotates, driving the connecting rod frame 206 to rotate, so that the connecting rod frame 206 is away from one side of the center of the gear rod 204, and rotates around the center of the gear rod 204, driving the sliding rod 205 to move up and down, so that the arc-shaped slide plate 202 moves. When the arc-shaped slide plate 202 descends, the spring block 208 and the conical block 207 are separated. Since the spring block 208 is in a squeezed state before, after separation, the resilience of the spring block 208 will be released, blocking the air intake slot at the top of the arc-shaped slide plate 202, so that the arc-shaped slide plate 202 is in a sealed state.

When the sliding plate 103 rises, the blocking plate 305 is separated from the fixed push rod 307. Since the blocking plate 305 is in a rotating state before, the arc spring 2 306 is squeezed at the same time. When the blocking plate 305 is separated from the fixed push rod 307, the rebound force of the arc spring 2 306 will be released, pushing the blocking plate 305 to return to its original position, so that the blocking plate 305 is in a horizontal state, thereby collecting the soil in a concentrated manner.

[0058] There is no limitation on the number of the above components, and relevant technicians in the field can freely set them according to actual needs, as long as the above components are installed at the corresponding component connection positions.

[0059] The construction method of the soft soil foundation drainage device comprises the following steps:

[0060] S1: Install the buried pipe pile 101 on the construction vehicle, then start the construction vehicle to insert the buried pipe pile 101 into the soft soil until the fixing plate 102 fits with the soil. After fitting, start the electric telescopic rod 106 to retract and drive the sliding plate 103 to rise;

[0061] S2: When the sliding plate 103 rises, the water inlet hole 1 of the buried pipe pile 101 and the water inlet hole 2 of the drum screen 104 are misaligned, so the buried pipe pile 101 is in a closed state. When the sliding plate 103 rises, negative pressure is generated at the bottom of the buried pipe pile 101, and as the sliding plate 103 continues to rise;

[0062] S3: It will contact with the sliding rod 107, push the sliding rod 107 up, and contact with the inclined piston rod 110. Since the contact surfaces of the sliding rod 107 and the inclined piston rod 110 are both inclined surfaces, the sliding rod 107 will smoothly push the inclined piston rod 110 to move.

[0063] A specific application of this embodiment is: when the present invention is used, the buried pipe pile 101 is installed on the construction vehicle, and then the construction vehicle is started to insert the buried pipe pile 101 into the soft soil until the fixing plate 102 fits with the soil. After fitting, the electric telescopic rod 106 is started to retract and drive the sliding plate 103 to rise. When the sliding plate 103 rises, the water inlet hole 1 of the buried pipe pile 101 and the water inlet hole 2 of the drum screen 104 are misaligned, so the buried pipe pile 101 is in a closed state. When the sliding plate 103 rises, negative pressure will be generated at the bottom of the buried pipe pile 101. As the sliding plate 103 continues to rise, it will contact the sliding rod 107, pushing the sliding rod 107 to rise and contact the inclined piston rod 110. The contact surfaces of 107 and the inclined piston rod 110 are both inclined surfaces, so the sliding rod 107 can smoothly push the inclined piston rod 110 to move, squeeze the hydraulic oil in the oil pipe 108, thereby pushing the arc piston rod 111 to move, driving the sliding block 112 to slide in the arc groove 109, and squeezing the arc spring 113. At the same time, when the sliding block 112 moves, it will also drive the drum screen 104 to rotate, so that the water inlet hole 1 is connected with the water inlet hole 2, so that the suction force generated by the negative pressure at the bottom of the buried pipe pile 101 will attract the water in the soil pores around the buried pipe pile 101, so that the water flows to the bottom of the buried pipe pile 101. This suction force enhances the flow of water, allowing the pore water to be drawn out faster, thereby accelerating the drainage speed in the soil;

[0064] The water discharged into the buried pipe pile 101 is pumped out through the pumping pipe 115 by starting the water pump 114. When the water pump 114 pumps water, the electric telescopic rod 106 is extended to make the sliding plate 103 drop, and the driving force on the sliding rod 107 will disappear. At this time, the sliding rod 107 will drop, and the driving force on the inclined piston rod 110 will also disappear. The resilience of the arc spring 113 will release and push the sliding block 112 back to its position, driving the drum screen 104 to return to its position, so that the buried pipe pile 101 is in a sealed state. When the sliding plate 103 is reset, the electric telescopic rod 106 is retracted again to make the sliding plate 103 rise, and so on, until the water in the soil around the buried pipe pile 101 is fully discharged by reciprocatingly extending and retracting the electric telescopic rod 106, and then the construction vehicle is started to take out the buried pipe pile 101 and replace the drainage position of the buried pipe pile 101.

[0065] Secondly, when the sliding plate 103 rises, it will squeeze the gas in the buried pipe pile 101, and the squeezed gas will enter the fixed cover 201. At the same time, the rising of the sliding plate 103 will drive the fixed cover 201 to rise. When the fixed cover 201 rises, the gear rod 204 will mesh with the rack 203, so that the gear rod 204 rotates, driving the connecting rod frame 206 to rotate, so that the connecting rod frame 206 is away from one side of the center of the gear rod 204, and rotates around the center of the gear rod 204, driving the sliding rod 205 to move up and down, so that the arc slide plate 202 moves. When the arc slide plate 202 descends, the spring block 208 and the conical block 207 are separated. Because the spring block 208 was in a squeezed state before, after separation, the resilience of the spring block 208 The air inlet groove on the top of the arc-shaped slide plate 202 is blocked, and the arc-shaped slide plate 202 is in a sealed state. When it descends, it can squeeze the gas entering the fixed cover 201 again, and the gas squeezed for the second time is guided through the inclined plate 209 to spray out the water inlet hole 1 of the buried pipe pile 101, so that the soil in the water inlet hole 1 splashes into the fixed cover 201, and the hole is cleaned. After the water inlet hole 1 and the water inlet hole 2 are connected, the suction force generated by the negative pressure will pull the soil in the water inlet hole 2 through the cleaned water inlet hole 1, and the soil in the water inlet hole 2 of the drum screen 104 will be sucked into the water inlet hole 1, so as to prevent the hole from being blocked and affecting the speed of water entering the buried pipe pile 101, so that the buried pipe pile 101 can maintain a normal water diversion speed for a long time;

[0066] Secondly, when the arc-shaped slide plate 202 descends, it will contact with the spring piston rod 303, squeezing the spring piston rod 303, so that the spring piston rod 303 squeezes the hydraulic oil 2 in the oil pipe 2 302, thereby pushing the arc-shaped piston rod 2 304 to move, pushing the sliding block 2 301 to slide in the fixed cover 201, pushing the soil splashed into the fixed cover 201 by the air flow, and letting the pushed soil fall onto the blocking plate 305. When the sliding plate 103 rises, the blocking plate 305 will be separated from the fixed push rod 307. Because the blocking plate 305 was in a rotating state before, it squeezed the arc spring 2 306 at the same time. When the blocking plate 305 is separated from the fixed push rod 307 After that, the rebound force of the arc spring 306 will be released, pushing the blocking plate 305 to reset, so that the blocking plate 305 is in a horizontal state, so that the soil can be collected in a centralized manner. When the sliding plate 103 is reset, the fixed push rod 307 will contact the blocking plate 305, pushing the blocking plate 305 to rotate, so that the soil falling on the blocking plate 305 slides to the bottom of the buried pipe pile 101 and is discharged through the pumping pipe 115, so as to avoid the soil existing for too long when the jet is used to clean the water inlet hole 1, which may cause blockage in the fixed cover 201 and affect the flow of gas. By discharging the soil in time, the risk of blockage is reduced, and the smooth flow of gas is ensured, so that a good cleaning effect can be maintained.

[0067] Secondly, when the sliding plate 103 rises, it will also drive the connecting rod 308 and the spring sliding ring 309 to rise. As the sliding plate 103 continues to rise, the fixing rod 314 will also contact the connecting plate 311. When the connecting plate 311 contacts the fixing rod 314, the fixing rod 314 will push the connecting plate 311 down, drive the spring sliding ring 309 down, and fold the connecting plate 311, pushing the support block 313 close to the inner wall of the buried pipe pile 101 until the support block 313 and the buried pipe pile are in contact. The inner wall of the buried pipe pile 101 is contacted to support the inner wall of the buried pipe pile 101. At the same time, the sliding plate 103 is also in contact with the spring sliding cylinder 316, pushing the spring sliding cylinder 316 to rise, allowing the connecting rod 318 to fold, pushing the conical insert rod 317 to move and insert into the soil, thereby enhancing the stability of the buried pipe pile 101. By enhancing the stability of the buried pipe pile 101, the settlement and tilting of the buried pipe pile 101 caused by external force or soil deformation are prevented, and the long-term stability of the buried pipe pile 101 is maintained.
