Description

Technical Field

[0001] The invention relates to the technical field of construction engineering equipment, in particular to a seepage-promoting structure for soft soil foundation and a construction method thereof. Background Art

[0002] Soft soil refers to fine-grained soil deposited in coastal areas, lakes, valleys, and riverbanks with high natural water content, large porosity, high compressibility, and low shear strength. It has the characteristics of high natural water content, large natural porosity, high compressibility, low shear strength, small consolidation coefficient, long consolidation time, high sensitivity, high disturbance, poor permeability, complex layered distribution of soil layers, and large differences in physical and mechanical properties between layers.

[0003] Since soft soil has the characteristic of poor water permeability, in rainy weather, rainwater tends to accumulate in the shallow layer of the soft soil foundation and is not easy to diffuse into the deep layer of the soft soil foundation, thereby increasing the porosity and compressibility of the soft soil, affecting the stability of the buildings on the soft soil foundation. In response to the above problems, the following solutions are proposed. Summary of the invention

[0005] The anti-blocking mechanism includes a hydraulic groove 1 provided on the inner wall of the side drain pipe, a clamping spring fixedly connected to the inner wall of the main drain pipe, and a sliding block slidably connected to the inner wall of the main drain pipe;

[0006] The stirring mechanism comprises two hydraulic grooves arranged on the inner wall of the side drainage pipe, a fixed block is fixedly connected to the inner wall of the main drainage pipe, and a push rod is fixedly connected to the outer wall of the fixed block.

[0007] Preferably, the infiltration promoting mechanism also includes a telescopic protective sleeve fixedly connected to the outer wall of the main drain pipe, a sliding tube is slidably connected to the inner wall of the main drain pipe, the outer wall of the sliding tube is fixedly connected to the inner wall of the telescopic protective sleeve, a telescopic spring is fixedly connected to the outer wall of the sliding tube, and the outer wall of the telescopic spring is fixedly connected to the bottom of the main drain pipe. The telescopic protective sleeve can prevent the main drain pipe from sliding downward with the sliding pipe, thereby preventing the soil and gravel around the hole from adhering to the outer surface of the sliding pipe and affecting the downward sliding of the main drain pipe. The telescopic spring ensures that the main drain pipe will continue to move downward when the sliding pipe touches the bottom, and will squeeze the side drain pipe to extend outward, thereby preventing the side drain pipe from extending outward prematurely due to gravel protrusions in the middle of the downward movement, so that the device cannot reach the designated position, thereby affecting the normal use of the equipment.

[0008] Preferably, the infiltration promoting mechanism also includes a flow slot 1 provided on the outer wall of the sliding tube, a conical head is fixedly connected to the top of the sliding tube, and a flow slot 2 is provided on the outer wall of the conical head. The sliding tube contacts the bottom when the main drain pipe is inserted downward, and the side drain pipe is pushed upward to extend outward by its reaction force. A hole is first drilled in advance at the position where the main drain pipe needs to be inserted, and then the main drain pipe is inserted into the pre-drilled hole. When the main drain pipe is inserted downward, the sliding tube at the bottom of the main drain pipe first contacts the bottom surface of the hole, and then the main drain pipe slides downward along with the outer surface of the sliding tube. At this time, the telescopic protective cover and the telescopic spring contract at the same time to prevent the surrounding soil and gravel from affecting the downward sliding of the main drain pipe. When the main drain pipe is downward The conical head on the top of the sliding pipe contacts the bottom of the side drain pipe, and then the side drain pipe is pushed back to extend outward and inserted into the deep of the soft soil foundation, so that it can share a certain pressure for the main drain pipe in the rainy season, and the accumulated water in the main drain pipe can penetrate to the surrounding areas deep in the soft soil foundation, avoiding excessive pressure on the main drain pipe due to excessive rain, resulting in the failure of the accumulated water inside the main drain pipe to be discharged to the bottom in time, thereby causing excessive water accumulation in the shallow layer of the soft soil foundation, which has a certain impact on the buildings on the soft soil foundation. At the same time, the side drain pipe is extended outward from the bottom of the hole, avoiding the bending or damage of the side drain pipe due to the protruding gravel and debris inside the hole when the side drain pipe is inserted downward into the main drain pipe, thereby affecting the overall use effect.

When the side drain pipe extends outward to the maximum value, the sliding block pops up downward to push the sliding plate, and an L-shaped partition is provided. When the side drain pipe extends outward to the point where the sliding block is in full contact with the sliding plate, the sliding block is acted upon by the clamping spring to pop up downward and squeeze the sliding plate. Downward, the hydraulic oil inside the hydraulic groove is squeezed downward, and in turn pushes the piston plate 1 upward. When the piston plate 1 moves upward, it pushes the L-shaped partition on its top to extend outward. After the upper and lower L-shaped partitions extend outward, the originally closed water outlet holes on the outside of the side drain pipe open, so that the side drain pipe can operate normally, and the infiltration of accumulated water is promoted, which avoids the blockage of the inner wall of the side drain pipe due to the surrounding soil when the side drain pipe is extended outward, thereby affecting the effect of the side drain pipe to drain water outward, and reducing the infiltration efficiency of the overall pipeline.

[0010] Preferably, the anti-clogging mechanism also includes a piston plate slidably connected to the inner wall of the side drain pipe, an L-shaped partition is slidably connected to the inner wall of the side drain pipe, the outer wall of the L-shaped partition is fixedly connected to the top of the piston plate 1, and the top of the L-shaped partition is slidably connected to the inner wall of the main drain pipe. Utilizing the above-mentioned characteristics that the side drain pipe and the L-shaped partition are forced to extend outward, when the main drain pipe is inserted downward, the side drain pipe slides along the outer surface of the sliding pipe, so that the conical head at the top of the sliding pipe pushes it upward to extend outward, and the L-shaped partition is a sliding block that pops out downward to squeeze the sliding plate, so that the hydraulic oil in the hydraulic groove 1 is pushed through the piston plate 1 It extends outward, and after the side drainage pipe and the L-shaped baffle extend outward, they will be inserted into the deep part of the soft soil foundation. Compared with the shallow part of the soft soil foundation, the deep part of the soft soil foundation has a higher degree of consolidation, lower compressibility and permeability, stronger shear strength and more stable engineering properties. After the side drainage pipe and the L-shaped baffle are inserted outward into the deep part of the soft soil foundation, the entire infiltration promotion device will be more firmly inserted into the soft soil foundation at a set position, avoiding the shifting and tilting of the position of the entire device due to the looseness of the middle and shallow parts of the soft soil foundation with long-term use, affecting its normal use and reducing the infiltration promotion efficiency.

[0011] Preferably, the stirring mechanism also includes a piston plate 2 fixedly connected to the outer wall of the push rod, the outer wall of the piston plate 2 is slidably connected to the inner wall of the side drain pipe, the outer wall of the fixed block is slidably connected to the inner wall of the side drain pipe, the outer wall of the push rod is slidably connected to the inner wall of the side drain pipe, the inner wall of the side drain pipe is rotatably connected with a connecting shaft, the outer wall of the connecting shaft is fixedly connected with rotating teeth, the outer wall of the rotating teeth is rotatably connected to the inner wall of the side drain pipe, the push rod can pull the hydraulic oil inside the hydraulic groove 2 to move through the piston plate 2, and when the hydraulic oil moves, the rotating teeth are squeezed by the hydraulic oil and rotate inside the side drain pipe with the connecting shaft as the axis, thereby providing necessary power support for the operation of subsequent components.

[0012] Preferably, the stirring mechanism also includes a circular partition rotatably connected to the outer wall of the connecting shaft, the outer wall of the circular partition is fixedly connected to the inner wall of the side drain pipe, a belt is sleeved on the outer wall of the connecting shaft, a U-shaped protective sleeve is fixedly connected to the outer wall of the side drain pipe, a stirring column is rotatably connected to the inner wall of the U-shaped protective sleeve, and a belt is sleeved on the outer wall of the stirring column. Utilizing the characteristic that when the side drain pipe moves outward, the push rod pulls the hydraulic oil in the second hydraulic groove, a rotating tooth is provided, and when the side drain pipe moves outward, the push rod pulls the hydraulic oil in the second hydraulic groove through the second piston plate to move, and when the hydraulic oil moves, the rotating gear is driven The movable teeth rotate, thereby driving the connecting shaft to rotate. When the connecting shaft rotates, the stirring column is synchronously driven to rotate through the transmission of the belt, so that when the side drain pipe is extended outward, the stirring column continuously stirs the soil and gravel around the side drain pipe, making the soil and gravel around the side drain pipe looser, thereby reducing the pressure of the side drain pipe when it is extended outward, and also reducing the pressure of the L-shaped partition when it is extended outward, avoiding the soil and gravel around the side drain pipe being too compact, causing excessive resistance when the two are extended, resulting in damage or jamming when extended, thereby affecting the penetration efficiency of the equipment.

[0013] A construction method for a permeability-enhancing structure for a soft soil foundation comprises the following steps:

[0014] S1: First, a hole is drilled in advance at the position where the main drainage pipe is to be inserted, and then the main drainage pipe is inserted into the hole drilled in advance. When the main drainage pipe is inserted downward, the sliding pipe at the bottom of the main drainage pipe first contacts the bottom surface of the hole;

[0015] S2: Then, the main drainage pipe slides downward along the outer surface of the sliding pipe, and the telescopic protective cover and the telescopic spring shrink at the same time to prevent the surrounding soil and gravel from affecting the downward sliding of the main drainage pipe;

[0016] S3: When the main drain pipe is downward, the conical head on the top of the sliding pipe contacts the bottom of the side drain pipe, and then pushes the side drain pipe outward and inserts it into the depth of the soft soil foundation.

[0017] The present invention has the following beneficial effects:

[0018] (1) The present invention utilizes the characteristic that when the main drain pipe is inserted downward, the sliding pipe contacts the bottom and is pushed upward by its reaction force to extend the side drain pipe outward. First, a hole is drilled in advance at the position where the main drain pipe needs to be inserted, and then the main drain pipe is inserted into the pre-drilled hole. When the main drain pipe is inserted downward, the sliding pipe at the bottom of the main drain pipe first contacts the bottom surface of the hole, and then the main drain pipe slides downward along with the outer surface of the sliding pipe. At this time, the telescopic protective sleeve and the telescopic spring are contracted at the same time to prevent the surrounding soil and gravel from affecting the downward sliding of the main drain pipe. When the main drain pipe is downward, the conical head at the top of the sliding pipe contacts the bottom of the side drain pipe, and then pushes back. The side drain pipe extends outward and is inserted deep into the soft soil foundation, so that it can share a certain amount of pressure for the main drain pipe during the rainy season, and the accumulated water in the main drain pipe can penetrate to the surrounding areas deep in the soft soil foundation, to avoid excessive pressure in the main drain pipe due to excessive rain, which can cause the accumulated water inside the main drain pipe to fail to be discharged to the bottom in time, thereby causing excessive accumulation of water in the shallow layer of the soft soil foundation, which has a certain impact on the buildings on the soft soil foundation. At the same time, the side drain pipe extends outward from the bottom of the hole, to avoid the side drain pipe being bent or damaged by the protruding gravel and debris inside the hole when the main drain pipe is inserted downward, thereby affecting the overall use effect.

[0019] (2) The present invention utilizes the characteristic that when the side drain pipe is extended outward to the maximum value, the sliding block pops up downward and pushes the sliding plate, and sets an L-shaped partition. When the side drain pipe is extended outward and extends to the point where the sliding block is in full contact with the sliding plate, the sliding block is acted upon by the clamping spring to pop up downward and squeeze the sliding plate downward, so that the hydraulic oil inside the hydraulic tank 1 is squeezed downward, and in turn pushes the piston plate 1 upward to move upward. When the piston plate 1 moves upward, it pushes the L-shaped partition on its top to extend outward. After the upper and lower L-shaped partitions extend outward, the water outlet holes on the outer side of the side drain pipe that were originally closed open, so that the side drain pipe can operate normally, promoting the infiltration of accumulated water, and avoiding the side drain pipe's inner wall being blocked by the surrounding soil when it is extended outward, thereby affecting the side drain pipe's drainage effect and reducing the overall infiltration efficiency of the pipeline.

[0020] (3) The present invention utilizes the above-mentioned characteristics that the side drain pipe and the L-shaped partition are forced to extend outward. When the main drain pipe is inserted downward, the side drain pipe slides along with the outer surface of the sliding pipe, so that the conical head on the top of the sliding pipe pushes it upward to extend outward, and the L-shaped partition is a sliding block that pops out downward to squeeze the sliding plate, so that the hydraulic oil inside the hydraulic tank is pushed outward through the piston plate. After the side drain pipe and the L-shaped partition are extended outward, they will be inserted into the deep part of the soft soil foundation. Compared with the shallow part of the soft soil foundation, the deep part of the soft soil foundation has a higher degree of consolidation, lower compressibility and permeability, stronger shear strength and more stable engineering properties. After the side drain pipe and the L-shaped partition are inserted outward into the deep part of the soft soil foundation, the entire infiltration enhancement device will be more firmly inserted into the soft soil foundation at a set position, avoiding the displacement and tilting of the position of the entire device due to the looseness of the middle and shallow parts of the soft soil foundation with long-term use, affecting its normal use and reducing the infiltration enhancement efficiency.

[0021] (4) The present invention utilizes the characteristic that when the side drain pipe moves outward, the push rod pulls the hydraulic oil in the second hydraulic groove to set a rotating tooth. When the side drain pipe moves outward, the push rod pulls the hydraulic oil in the second hydraulic groove through the second piston plate to move. When the hydraulic oil moves, the rotating tooth is driven to rotate, and then the connecting shaft is driven to rotate. When the connecting shaft rotates, the stirring column is synchronously driven to rotate through the transmission of the belt, so that when the side drain pipe is extended outward, the stirring column continuously stirs the soil and gravel around the side drain pipe, making the soil and gravel around the side drain pipe looser, thereby reducing the pressure of the side drain pipe when it is extended outward, and also reducing the pressure of the L-shaped partition when it is extended outward, avoiding the soil and gravel around the side drain pipe being too compact, resulting in excessive resistance when the two are extended, resulting in damage or jamming when extended, thereby affecting the penetration efficiency of the equipment.

[0034] 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.

[0035] For example, see Figure 1 - Figure 4 The present invention is a seepage-promoting structure for soft soil foundation, comprising a seepage-promoting mechanism 1, wherein the seepage-promoting mechanism 1 further comprises a main drainage pipe 101, a side drainage pipe 102 is slidably connected to the inner wall of the main drainage pipe 101, and a sandstone seepage-promoting groove 103 is fixedly connected to the top of the main drainage pipe 101;

[0038] The infiltration promoting mechanism 1 also includes a telescopic protective sleeve 104 fixedly connected to the outer wall of the main drainage pipe 101, a sliding tube 105 is slidably connected to the inner wall of the main drainage pipe 101, the outer wall of the sliding tube 105 is fixedly connected to the inner wall of the telescopic protective sleeve 104, and a telescopic spring 106 is fixedly connected to the outer wall of the sliding tube 105, and the outer wall of the telescopic spring 106 is fixedly connected to the bottom of the main drainage pipe 101. The telescopic protective sleeve 104 prevents the main drainage pipe 101 from sliding downward with the sliding tube 105 due to the adhesion of soil and gravel around the hole to the outer surface of the sliding tube 105, thereby affecting the downward sliding of the main drainage pipe 101. The telescopic spring 106 ensures that when the sliding tube 105 touches the bottom, the main drainage pipe 101 continues to move downward to squeeze the side drainage pipe 102 to extend outward, thereby preventing the side drainage pipe 102 from extending outward prematurely due to gravel protrusions in the middle of the downward movement, so that the device cannot reach the specified position, thereby affecting the normal use of the equipment.

[0039] The infiltration promoting mechanism 1 also includes a flow slot 107 provided on the outer wall of the sliding tube 105, a conical head 108 is fixedly connected to the top of the sliding tube 105, and a flow slot 2 109 is provided on the outer wall of the conical head 108. When the main drainage pipe 101 is inserted downward, the sliding tube 105 contacts the bottom, and the side drainage pipe 102 is pushed upward to extend outward by its reaction force. First, a hole is drilled in advance at the position where the main drainage pipe 101 needs to be inserted, and then the main drainage pipe 101 is inserted into the pre-drilled hole. When the main drainage pipe 101 is inserted downward, the sliding tube 105 at the bottom of the main drainage pipe 101 first contacts the bottom surface of the hole, and then the main drainage pipe 101 slides downward along with the outer surface of the sliding tube 105. At this time, the telescopic protective cover 104 and the telescopic spring 106 shrink at the same time to prevent the surrounding soil and gravel from affecting the downward sliding of the main drainage pipe 101. When the main drain pipe 101 is downward, the conical head 108 on the top of the sliding pipe 105 contacts the bottom of the side drain pipe 102, and then pushes the side drain pipe 102 outward and inserts it into the deep of the soft soil foundation, so that it can share a certain pressure for the main drain pipe 101 in the rainy season, and the accumulated water in the main drain pipe 101 penetrates to the surrounding areas of the deep soft soil foundation, avoiding excessive pressure in the main drain pipe 101 due to excessive rainwater, resulting in the failure of the accumulated water inside the main drain pipe 101 to be discharged to the bottom in time, thereby causing excessive water accumulation in the shallow layer of the soft soil foundation, which has a certain impact on the buildings on the soft soil foundation. At the same time, the side drain pipe 102 is extended outward at the bottom of the hole, avoiding the side drain pipe 102 from being bent or damaged due to the protruding gravel and debris inside the hole when the main drain pipe 101 is inserted downward, thereby affecting the overall use effect.

The bottom of the sliding block 203 is slidably connected to the top of the side drainage pipe 102. When the side drainage pipe 102 extends outward to the maximum value, the sliding block 203 pops up downward to push the sliding plate 204. An L-shaped partition 206 is set. When the side drainage pipe 102 extends outward and extends to the point where the sliding block 203 is completely in contact with the sliding plate 204, the sliding block 203 is Due to the action of the clamping spring 202, it pops up downward and squeezes the sliding plate 204 downward, so that the hydraulic oil inside the hydraulic groove 201 is squeezed downward, and in turn pushes the piston plate 205 upward to move upward. When the piston plate 205 moves upward, it pushes the L-shaped partition 206 on its top to extend outward. After the upper and lower L-shaped partitions 206 extend outward, the originally closed water outlet holes on the outside of the side drain pipe 102 open, so that the side drain pipe 102 can operate normally, and the infiltration of accumulated water is promoted, which avoids the side drain pipe 102 from being blocked by the surrounding soil when it is extended outward, thereby affecting the effect of the side drain pipe 102 to drain water outward, and reducing the infiltration efficiency of the overall pipeline.

By utilizing the above-mentioned characteristics that the side drain pipe 102 and the L-shaped partition 206 are forced to extend outward, when the side drain pipe 102 is inserted downward into the main drain pipe 101, the outer surface of the sliding pipe 105 slides, so that the conical head 108 at the top of the sliding pipe 105 pushes it upward to extend outward, and the L-shaped partition 206 is the sliding block 203 that pops up downward to squeeze the sliding plate 204, so that the liquid The hydraulic oil inside the pressure groove 201 pushes it outward through the piston plate 205. After the side drainage pipe 102 and the L-shaped partition 206 are extended outward, they will be inserted into the deep part of the soft soil foundation. Compared with the shallow part of the soft soil foundation, the deep part of the soft soil foundation has a higher degree of consolidation, lower compressibility and permeability, stronger shear strength and more stable engineering properties. After the side drainage pipe 102 and the L-shaped partition 206 are inserted outward into the deep part of the soft soil foundation, the entire infiltration enhancement device will be more firmly inserted into the soft soil foundation at a set position, avoiding the position of the entire device being shifted and tilted due to the looseness of the middle and shallow parts of the soft soil foundation with long-term use, affecting its normal use and reducing the infiltration enhancement efficiency.

[0042] The stirring mechanism 3 also includes a piston plate 2 304 fixedly connected to the outer wall of the push rod 303, the outer wall of the piston plate 2 304 is slidably connected to the inner wall of the side drain pipe 102, the outer wall of the fixed block 302 is slidably connected to the inner wall of the side drain pipe 102, the outer wall of the push rod 303 is slidably connected to the inner wall of the side drain pipe 102, the inner wall of the side drain pipe 102 is rotatably connected with a connecting shaft 305, the outer wall of the connecting shaft 305 is fixedly connected with a rotating tooth 306, the outer wall of the rotating tooth 306 is rotatably connected to the inner wall of the side drain pipe 102, the push rod 303 can pull the hydraulic oil inside the hydraulic groove 2 301 to move through the piston plate 2 304, when the hydraulic oil moves, the rotating tooth 306 is squeezed by the hydraulic oil, and rotates inside the side drain pipe 102 with the connecting shaft 305 as the axis, thereby providing necessary power support for the operation of subsequent components.

When the side drain pipe 102 moves outward, the push rod 303 pulls the hydraulic oil in the hydraulic groove 2 301 through the piston plate 2 304 to move. When the hydraulic oil moves, it drives the rotating gear 306 to rotate, and then drives the connecting shaft 305 to rotate.

[0044] The construction method of the soft soil foundation infiltration promoting device comprises the following steps:

[0045] S1: First, a hole is drilled in advance at the position where the main drainage pipe 101 is to be inserted, and then the main drainage pipe 101 is inserted into the hole drilled in advance. When the main drainage pipe 101 is inserted downward, the sliding pipe 105 at the bottom of the main drainage pipe 101 first contacts the bottom surface of the hole;

[0046] S2: Then, the main drainage pipe 101 slides downward along the outer surface of the sliding pipe 105, and the telescopic protective cover 104 and the telescopic spring 106 shrink at the same time to prevent the surrounding soil and gravel from affecting the downward sliding of the main drainage pipe 101;

[0047] S3: When the main drain pipe 101 is downward, the conical head 108 at the top of the sliding pipe 105 contacts the bottom of the side drain pipe 102, and then pushes the side drain pipe 102 outward and inserts it into the depth of the soft soil foundation.

[0048] A specific application of this embodiment is as follows: before use, a hole is drilled in advance at the position where the main drain pipe 101 needs to be inserted, and then the main drain pipe 101 is inserted into the pre-drilled hole. When the main drain pipe 101 is inserted downward, the sliding tube 105 at the bottom of the main drain pipe 101 first contacts the bottom surface of the hole, and then the main drain pipe 101 slides downward along the outer surface of the sliding tube 105. At this time, the telescopic protective cover 104 and the telescopic spring 106 are contracted at the same time to prevent the surrounding soil and gravel from affecting the downward sliding of the main drain pipe 101. When the main drain pipe 101 moves downward, the conical head 108 at the top of the sliding tube 105 contacts the bottom of the side drain pipe 102, and then pushes the side drain pipe 102 backward. The side drain pipe 102 extends outward and is inserted deep into the soft soil foundation, so that it can share a certain pressure for the main drain pipe 101 in the rainy season, and the accumulated water in the main drain pipe 101 can penetrate to the surrounding areas deep in the soft soil foundation, so as to avoid excessive pressure in the main drain pipe 101 due to excessive rainwater, resulting in the failure of timely discharge of the accumulated water inside the main drain pipe 101 to the bottom, thereby causing excessive accumulation of water in the shallow layer of the soft soil foundation, which has a certain impact on the buildings on the soft soil foundation. At the same time, the side drain pipe 102 extends outward at the bottom of the hole, so as to avoid the side drain pipe 102 from being bent or damaged due to the protruding gravel and debris inside the hole when the main drain pipe 101 is inserted downward, thereby affecting the overall use effect.

[0049] Taking advantage of the fact that when the side drain pipe 102 extends outward to the maximum, the sliding block 203 pops up downward and pushes the sliding plate 204, an L-shaped partition 206 is provided. When the side drain pipe 102 extends outward to the point where the sliding block 203 is in full contact with the sliding plate 204, the sliding block 203 is acted upon by the clamping spring 202 to pop up downward and squeeze the sliding plate 204 downward, so that the hydraulic oil in the hydraulic tank 201 is squeezed downward, and in turn pushes the piston plate 205 upward to move upward. When the piston plate 205 moves upward, it pushes the L-shaped partition 206 on its top to extend outward. After the upper and lower L-shaped partitions 206 extend outward, the originally closed water outlet holes on the outer side of the side drainage pipe 102 are opened, so that the side drainage pipe 102 can operate normally, promoting the infiltration of accumulated water, and avoiding the blockage of the inner wall of the side drainage pipe 102 due to the surrounding soil when the side drainage pipe 102 is extended outward, thereby affecting the drainage effect of the side drainage pipe 102 and reducing the infiltration efficiency of the entire pipeline. When the main drain pipe 101 is inserted downward, the side drain pipe 102 slides along with the outer surface of the sliding pipe 105, so that the conical head 108 on the top of the sliding pipe 105 pushes it upward to extend outward, and the L-shaped partition 206 is the sliding block 203 that pops up downward to squeeze the sliding plate 204, so that the hydraulic oil inside the hydraulic tank 1 201 pushes it outward through the piston plate 1 205. After the side drain pipe 102 and the L-shaped partition 206 extend outward, they will be inserted into the depth of the soft soil foundation, which is much deeper than the shallow soft soil foundation. The deep part of the soft soil foundation has a higher degree of consolidation, lower compressibility and permeability, stronger shear strength and more stable engineering properties. After the side drainage pipe 102 and the L-shaped partition 206 are inserted outward into the deep part of the soft soil foundation, the entire infiltration enhancement device can be more firmly inserted into the soft soil foundation at a set position, avoiding the looseness of the middle and shallow parts of the soft soil foundation. With long-term use, the position of the entire device is not shifted and tilted, affecting its normal use and reducing the infiltration efficiency.

[0050] Taking advantage of the fact that when the side drain pipe 102 moves outward, the push rod 303 pulls the hydraulic oil in the hydraulic groove 2 301 to move, a rotating tooth 306 is provided. When the side drain pipe 102 moves outward, the push rod 303 pulls the hydraulic oil in the hydraulic groove 2 301 through the piston plate 2 304 to move. When the hydraulic oil moves, the rotating tooth 306 is driven to rotate, thereby driving the connecting shaft 305 to rotate. When the connecting shaft 305 rotates, the agitating column 310 is synchronously driven to rotate through the transmission of the belt 308, so that the side drain pipe 102 moves outward. When the pipe 102 is extended outward, the stirring column 310 continuously stirs the soil and gravel around the side drainage pipe 102, making the soil and gravel around the side drainage pipe 102 looser, thereby reducing the pressure of the side drainage pipe 102 when it is extended outward, and also reducing the pressure of the L-shaped partition 206 when it is extended outward, avoiding the side drainage pipe 102 being damaged or stuck when extended because the soil and gravel around the side drainage pipe 102 are too compact, resulting in excessive resistance when the two are extended, thereby affecting the penetration efficiency of the equipment.
