Description

Technical Field

[0001] This application relates to the field of slope drainage technology, and in particular to a highway slope drainage structure and its construction method. Background Technology

[0002] To maintain slope stability and ensure highway driving safety, drainage structures are usually installed on the slopes on both sides of the highway to drain groundwater from the slope rock mass.

[0003] In related technologies, slope drainage structures include multiple drainage pipes, a converging pipe installed on the slope, and a drainage ditch at the toe of the slope. The drainage pipes are inserted into the slope, and the converging pipe is installed longitudinally along the slope. The end of the drainage pipe located outside the slope is connected to the converging pipe, and the bottom end of the converging pipe extends into the drainage ditch. The portion of the drainage pipe inserted into the slope has multiple drainage holes. Groundwater within the slope seeps through the drainage holes into the drainage pipes, then enters the converging pipe, and finally flows into the drainage ditch for discharge.

[0004] Regarding the aforementioned technologies, after the drainage pipe is inserted into the slope, the soil on the slope easily clogs the drainage holes, causing blockage and reducing drainage efficiency. Summary of the Invention

[0005] To ensure drainage efficiency to a certain extent, this application provides a drainage structure for highway slopes and its construction method.

[0006] In the first aspect, the highway slope drainage structure provided in this application adopts the following technical solution: A highway slope drainage structure includes multiple drainage pipes for insertion into the slope, multiple drainage holes are opened on the drainage pipes, a sliding rod is slidably arranged inside the drainage pipe, the sliding direction of the sliding rod is parallel to the length direction of the drainage pipe, an elastic unblocking rod is provided on the sliding rod, the unblocking rod corresponds one-to-one with the drainage hole, the unblocking rod slidably passes through the corresponding drainage hole, the diameter of the unblocking rod is smaller than the diameter of the drainage hole, and a driving component for driving the sliding rod to slide back and forth is provided inside the drainage pipe.

[0007] By adopting the above technical solution, the sliding rod is driven to slide back and forth in the drain pipe by the drive component. This allows the sliding rod to move back and forth in the corresponding drain hole, which can unclog and loosen the drain hole to a certain extent. This makes it less likely for mud to clog the drain hole, and the drain hole always maintains gaps for drainage, thus helping to ensure drainage efficiency.

[0008] Preferably, the drainage pipe is inclined downwards towards one side of the slope, and the end of the drainage pipe outside the slope is connected to a connecting pipe. The angle between the side of the connecting pipe near the slope and the lower side of the drainage pipe is less than 180°. The driving assembly includes a connecting rope on the sliding rod, a pulling member inside the drainage pipe, and a retracting member inside the connecting pipe. The pulling member is used to pull the sliding rod to slide away from the connecting pipe, and the retracting member is used to pull or release the connecting rope.

[0009] By adopting the above technical solution, the connecting rope is pulled by the retractor, causing the sliding rod to slide towards the connecting pipe, thereby moving the unblocking rod within the corresponding drainage hole. When the connecting rope is released by the retractor, the sliding rod is pulled away from the connecting pipe by the puller, causing the unblocking rod to move in the opposite direction within the drainage hole. This reciprocating sliding of the sliding rod allows it to move back and forth a certain distance within the corresponding drainage hole, helping to unclog and loosen the drainage hole, preventing soil from clogging it, and thus ensuring drainage efficiency to a certain extent.

[0010] Preferably, the receiving / releasing component includes a first transmission plate slidably disposed within the connecting pipe, a second transmission plate slidably disposed within the connecting pipe, a guide plate rotatably disposed within the connecting pipe, a first pull rope disposed on the first transmission plate, a second pull rope disposed on the second transmission plate, a first spring disposed within the connecting pipe, and a second spring disposed within the connecting pipe. The sliding direction of the first and second transmission plates is parallel to the length direction of the connecting pipe. The first transmission plate is located on the side of the connecting pipe closer to the slope, and the second transmission plate is located on the side of the connecting pipe away from the slope. The end of the connecting rope away from the sliding rod is disposed on the first transmission plate, and the guide plate is located above the second transmission plate. The rotation axis of the plate is perpendicular to the length direction of the connecting pipe. The guide plate rotates towards or away from the first transmission plate. The guide plate is used to block the first transmission plate or the second transmission plate. The end of the first pull rope away from the first transmission plate is set on the guide plate. The end of the second pull rope away from the second transmission plate is set on the guide plate. The first spring is used to push the first transmission plate to slide towards the drain pipe. One end of the first spring is set inside the connecting pipe and the other end is set on the first transmission plate. The second spring is used to push the second transmission plate to slide towards the drain pipe. One end of the second spring is set inside the connecting pipe and the other end is set on the second transmission plate.

[0011] By adopting the above technical solution, when groundwater seeps into the drainage pipe and enters the connecting pipe, it first flows towards the first transmission plate. Under the impact of the water flow, the first transmission plate moves away from the drainage pipe, compressing the first spring. The first transmission plate then pulls the sliding rod towards the connecting pipe via the connecting rope, and the first pull rope pulls the guide plate towards the first transmission plate, causing the guide plate to block the first transmission plate. At this time, the first spring pushes the first transmission plate towards the drainage pipe, reducing the tension of the connecting rope on the sliding rod. The pulling component then pulls the sliding rod... The rod slides away from the connecting pipe; then the groundwater in the drain pipe falls onto the second transmission plate through the guide plate, causing the second transmission plate to move downward away from the drain pipe, compressing the second spring. At this time, the second pull rope pulls the guide plate to rotate away from the first transmission plate, closing the second transmission plate and opening the first transmission plate. The groundwater in the connecting pipe continues to flow to the first transmission plate. This process repeats, realizing the reciprocating movement of the sliding rod. This allows the sliding rod to move the unblocking rod within the corresponding drain hole, thus unblocking the drain hole and helping to ensure drainage efficiency.

[0012] Preferably, the pulling member includes a tension spring for pulling the sliding rod to slide away from the connecting pipe, one end of the tension spring being disposed inside the drain pipe and the other end being disposed on the sliding rod.

[0013] By adopting the above technical solution, the sliding rod is pulled by the tension spring to move away from the connecting pipe, so that the sliding rod drives the unblocking rod to move in the corresponding drainage hole, which helps to loosen the drainage hole and ensures drainage efficiency to a certain extent.

[0014] Preferably, the first transmission plate is provided with a first collection box for receiving ground water, the end of the connecting rope away from the sliding rod is provided on the first collection box, the end of the first pull rope away from the guide plate is provided on the first collection box, a first through hole is provided on the bottom wall of the first collection box, the first through hole penetrates the first transmission plate, the second transmission plate is provided with a second collection box for receiving ground water, the end of the second pull rope away from the guide plate is provided on the second collection box, the guide plate is located above the second collection box, a second through hole is provided on the bottom wall of the second collection box, the second hole penetrates the second transmission plate.

[0015] By adopting the above technical solution, the setting of the first accumulation box and the second accumulation box helps to collect a certain amount of groundwater. As the groundwater in the first accumulation box increases, the weight increases, which effectively ensures that the first transmission plate can pull the sliding rod to move and pull the guide plate to rotate, providing convenience for the sliding rod to slide. The setting of the first through hole and the second through hole helps to allow the groundwater in the first accumulation box and the second accumulation box to flow out gradually, reducing the weight and providing convenience for the reciprocating rotation of the guide plate.

[0016] Preferably, the drain rod has multiple branch rods arranged circumferentially on the side near the drain hole, and the distance from the end of the branch rod away from the drain rod to the center of the drain rod is less than the radius of the drain hole.

[0017] By adopting the above technical solution, the setting of the bifurcated rod helps to improve the dredging effect of the drainage hole, reduce the possibility of mud clogging the hole, and further ensure drainage efficiency.

[0018] Preferably, a bend is connected between the drain pipe and the connecting pipe, an air bladder is installed inside the bend, the end of the sliding rod near the connecting pipe is mounted on the air bladder, an inflation connector for inflating the air bladder is provided on the bend, an on / off valve is provided on the inflation connector, a sealing plug for opening and closing the drain hole is provided at the end of the unblocking rod away from the sliding rod, the sealing plug is located on the side of the forked rod away from the sliding rod, the sealing plug is inserted into the corresponding drain hole, and a valve is installed at the end of the connecting pipe away from the bend.

[0019] By adopting the above technical solution, the drain pipe is immersed in the water tank, with the sealing plug located outside the drain pipe, filling it with water. Inflation is then performed through the inflation connector, causing the airbag to push the sliding rod away from the connecting pipe, compressing the tension spring. The sliding rod then moves the unblocking rod and the sealing plug closer to the drain pipe, sealing the drain hole. The on / off valve is then closed, and the valve on the connecting pipe is shut off, forming a siphon structure. After the drain pipe is inserted into the slope, the air is drawn out of the airbag through the inflation connector, causing the airbag to move the sliding rod closer to the connecting pipe, stretching the tension spring. The spring moves the drain rod closer to the drain hole, causing the sealing plug to move out of the drain hole. As the airbag shrinks, it creates negative pressure at the bend, which can actively absorb groundwater in the slope. Then, the valve is opened, allowing groundwater to flow out along the connecting pipe, thus helping to efficiently drain slope seepage and ensure drainage efficiency. Next, a certain amount of gas is injected into the airbag, causing the tension spring to pull the sliding rod away from the connecting pipe. The tension spring is in its natural state, and there is still some space inside the airbag, which provides the possibility for the sliding rod to slide back and forth, helping the groundwater in the drain pipe to flow into the connecting pipe.

[0020] Preferably, the highway slope drainage structure also includes an air pump installed on the slope, the air pump being connected to an air supply pipe, and the air filling pipe being connected to the air supply pipe via a delivery pipe.

[0021] By adopting the above technical solution, the air pump is started, and the airbag can be inflated or inhaled through the air delivery pipe and the air supply pipe, so that the state of the airbag can be adjusted as needed.

[0022] Preferably, the sealing plug has a water inlet groove on the side opposite to the unblocking rod.

[0023] By adopting the above technical solution, the water inlet trough is designed so that the sealing plug will not easily block the drainage hole completely after it is removed from the drainage hole. Groundwater can enter the drainage hole through the water inlet trough and then seep into the drainage pipe, which helps to ensure drainage efficiency.

[0024] Secondly, the construction method for a highway slope drainage structure provided in this application adopts the following technical solution:

[0025] A construction method for a highway slope drainage structure includes the following steps:

[0026] Step 1: Insert the drainage pipe into the predetermined position on the slope, so that the side of the drainage pipe closest to the slope is tilted downwards;

[0027] Step 2: Connect the connecting pipe to the longitudinal converging pipe of the slope;

[0028] Step 3: Groundwater in the slope seeps into the drainage pipe through the drainage hole. The connecting rope is pulled by the retractor, and the connecting rope pulls the sliding rod to slide towards the connecting pipe, so that the unblocking rod moves in the corresponding drainage pipe.

[0029] Step 4: Loosen the connecting rope using the release mechanism, and pull the sliding rod away from the connecting pipe using the pull mechanism. This will cause the unblocking rod to move within the drain hole, achieving the purpose of reciprocating vibration of the unblocking rod within the drain hole.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. By driving the sliding rod to slide back and forth in the drain pipe through the drive component, the sliding rod can drive the unblocking rod to move back and forth in the corresponding drain hole, which can unblock and loosen the drain hole to a certain extent, so that the soil is less likely to clog the drain hole, and the drain hole always maintains gaps for drainage, thus helping to ensure drainage efficiency.

[0032] 2. Immerse the drain pipe in the pool, with the sealing plug outside the drain pipe, filling it with water. Inflate the air bladder through the inflation connector, causing the air bladder to push the sliding rod away from the connecting pipe. The sliding rod then moves the sealing plug to block the drain hole. Close the on / off valve and the valve on the connecting pipe, forming a siphon structure. After inserting the drain pipe onto the slope, evacuate the air bladder through the inflation connector, causing the air bladder to move the sliding rod closer to the connecting pipe. This stretches the tension spring, moving the unblocking rod closer to the drain hole, causing the sealing plug to move out of the drain hole. As the air bladder shrinks, a negative pressure is created at the bend, actively adsorbing groundwater from the slope. Then, open the valve, allowing the groundwater to flow out along the connecting pipe, thus efficiently draining slope seepage and ensuring drainage efficiency. Attached Figure Description

[0039] The following will be combined with the appendix Figures 1-5 This invention will be described in detail, and the technical solutions in the embodiments of this invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0040] This application discloses a drainage structure for highway slopes. (Refer to...) Figure 1 and Figure 2The highway slope drainage structure includes multiple drainage pipes 1 for insertion into the slope and an air pump 26 for installation on the slope. The multiple drainage pipes 1 are arranged longitudinally along the slope. The side of the drainage pipe 1 closest to the slope is inclined downward. The end of the drainage pipe 1 outside the slope is connected to a bend 20. The end of the bend 20 away from the drainage pipe 1 is connected to a connecting pipe 5. The angle between the side of the connecting pipe 5 closest to the slope and the lower side of the drainage pipe 1 is less than 180°. In this embodiment, the length direction of the connecting pipe 5 is parallel to the slope surface. All connecting pipes 5 in the longitudinal direction of the slope are connected to a converging pipe, through which groundwater is discharged into the drainage ditch.

[0041] Reference Figure 3 and Figure 4 The drain pipe 1 has multiple drain holes 2, each with a smaller outer diameter and a larger inner diameter, meaning the diameter of the drain hole 2 closer to the drain pipe 1 is larger than the diameter of the side farther from the drain pipe 1, which helps with soil and water separation. A sliding rod 3 is slidably installed inside the drain pipe 1, with the sliding direction of the sliding rod 3 parallel to the length of the drain pipe 1. A first telescopic rod 30 is fixedly connected to the side of the sliding rod 3 away from the bend 20. The end of the first telescopic rod 30 away from the sliding rod 3 is fixed to the bottom wall of the drain pipe 1, and the extension / retraction direction of the first telescopic rod 30 is parallel to the sliding direction of the sliding rod 3. An elastic unblocking rod 4 is fixedly connected to the sliding rod 3. The unblocking rod 4 is a high-strength elastic steel rod, and it corresponds one-to-one with each drain hole 2. The unblocking rod 4 slidably passes through the corresponding drain hole 2. The unblocking rod 4 is an arc-shaped rod, with the end of the unblocking rod 4 away from the corresponding drain hole 2 tilted downwards. The diameter of the unblocking rod 4 is smaller than the diameter of the drain hole 2. A drive assembly is installed inside the drain pipe 1 to drive the sliding rod 3 to slide back and forth.

[0042] Reference Figure 3 and Figure 4 To facilitate the reciprocating sliding of the sliding rod 3, the drive assembly includes a connecting rope 6 fixedly installed at one end of the sliding rod 3 near the connecting pipe 5, a pulling member installed inside the drain pipe 1, and a retracting member installed inside the connecting pipe 5. The retracting member is used to pull or release the connecting rope 6, and the pulling member is used to pull the sliding rod 3 to slide away from the connecting pipe 5. The pulling member includes a tension spring 14 for pulling the sliding rod 3 to slide away from the connecting pipe 5. The tension spring 14 is movably sleeved on the first telescopic rod 30. One end of the tension spring 14 is fixedly connected to the bottom wall of the drain pipe 1, and the other end is fixedly connected to the end of the sliding rod 3 away from the connecting pipe 5.

[0043] Reference Figure 3 and Figure 4An airbag 21 is movably installed inside the bend 20. The central part of the top side of the airbag 21 is fixedly connected to the inner wall of the upper side of the bend 20, so that the airbag 21 is not easy to shift when inflated. An inflation connector 22 for inflating the airbag 21 is fixedly installed on the bend 20. An opening and closing valve 23 is installed on the inflation connector 22. The end of the sliding rod 3 near the connecting pipe 5 is fixedly connected to the airbag 21. The end of the unblocking rod 4 away from the sliding rod 3 is fixedly connected to a sealing plug 24 for opening and closing the drain hole 2. The plug 24 is inserted into the corresponding drain hole 2. In this embodiment, the plug 24 is a rubber plug, so that after the plug 24 is removed from the drain pipe 1, it is not easy to insert it into the drain hole 2 again. Limiting rods 31 are fixed on opposite sides of the inner wall of the drain hole 2. The limiting rods 31 are located on the side of the plug 24 near the unblocking rod 4. The limiting rods 31 are used to abut against the side of the plug 24 near the unblocking rod 4, so that when the sliding rod 3 moves, it is not easy to completely move the plug 24 into the drain pipe 1.

[0044] Reference Figure 1 and Figure 2 An air pump 26 is connected to an air supply pipe 27, which is set along the longitudinal direction of the slope. An air filling pipe 22 is connected to the air supply pipe 27 through a delivery pipe 28. A valve 25 is fixedly installed at the end of the connecting pipe 5 away from the bend 20.

[0045] During construction, first place the drain pipe 1 into the water tank. At this time, the sealing plug 24 is located outside the sliding rod 3, filling the drain pipe 1 with water. Then, open the on / off valve 23 and use an external tool to supply air into the inflation connector 22, causing the airbag 21 to inflate. At this time, the expansion of the airbag 21 pushes the sliding rod 3 to move away from the connecting pipe 5, compressing the tension spring 14. The sliding rod 3 drives the unblocking rod 4 to slide closer to the drain pipe 1, causing the sealing plug 24 to move into the drain hole 2 and seal the drain hole 2. At this time, the airbag 21 is inflated. Close the on / off valve 23, and then close the valve 25 on the connecting pipe 5, thus forming a siphon tube; then... The drain pipe 1 is inserted into a suitable position on the slope. The air pump 26 is installed on the slope surface. The air supply pipe 27 is connected to the inflation connector 22 through the delivery pipe 28. Then, the connecting pipe 5 is connected to the converging pipe. Next, the on / off valve 23 is opened, and the air pump 26 is started. The air pump 26 extracts the gas from the airbag 21 through the air supply pipe 27 and the delivery pipe 28. At this time, the airbag 21 deflates, causing the tension spring 14 to stretch and form a negative pressure. At the same time, the airbag 21 drives the sliding rod 3 to slide towards the connecting pipe 5, causing the unblocking rod 4 to push the sealing plug 24 away from the drain pipe 1, so that the sealing plug 24 is removed from the drain hole 2 on the drain pipe 1. At this time, groundwater in the slope flows into drainage pipe 1 through drainage hole 2. Due to the negative pressure formed in the bend 20, an active water suction phenomenon is formed. Then, valve 25 is opened, and groundwater can flow into connecting pipe 5 along bend 20, and then be discharged into drainage ditch from the converging pipe, realizing active drainage and improving drainage efficiency to a certain extent. Then, air pump 26 is started to inject an appropriate amount of gas into air inlet pipe 22, causing tension spring 14 to pull sliding rod 3 a certain distance away from connecting pipe 5, so that tension spring 14 is in its natural state. At this time, there is still space in airbag 21, which can meet the reciprocating sliding of sliding rod 3. Then, the retraction device pulls... The connecting rope 6 is moved so that the sliding rod 3 moves toward the connecting pipe 5, and the tension spring 14 is stretched, causing the unblocking rod 4 to move away from the drain pipe 1. The connecting rope 6 is released by the release mechanism. At this time, the tension of the connecting rope 6 on the sliding rod 3 is reduced. At this time, the tension spring 14 causes the sliding rod 3 to move away from the connecting pipe 5, and the unblocking rod 4 moves toward the drain pipe 1. This process is repeated to realize the reciprocating movement of the sliding rod 3, which allows the unblocking rod 4 to move back and forth in the drain hole 2, clearing and loosening the drain hole 2, so that the soil is less likely to clog the drain hole 2, thus ensuring drainage efficiency to a certain extent.

[0046] Reference Figure 3 and Figure 5To facilitate pulling or releasing the connecting rope 6, the retractable component includes a first transmission plate 7 slidably disposed within the connecting pipe 5, a second transmission plate 8 slidably disposed within the connecting pipe 5, a guide plate 9 rotatably disposed within the connecting pipe 5, a first pull rope 10 disposed on the first transmission plate 7, a second pull rope 11 disposed on the second transmission plate 8, a first spring 12 disposed within the connecting pipe 5, and a second spring 13 disposed within the connecting pipe 5. The sliding direction of the first transmission plate 7 and the second transmission plate 8 is parallel to the length direction of the connecting pipe 5. The first transmission plate 7 is located on the side of the connecting pipe 5 closest to the slope, and the second transmission plate 9... 8 is located on the side of the connecting pipe 5 away from the slope. A first mounting plate 32 and a second mounting plate 33 are fixedly connected inside the connecting pipe 5. The first mounting plate 32 is located on the side of the first transmission plate 7 away from the drain pipe 1. A second telescopic rod 34 is fixed between the first mounting plate 32 and the first transmission plate 7. The telescopic direction of the second telescopic rod 34 is parallel to the sliding direction of the first transmission plate 7. The second mounting plate 33 is located on the side of the second transmission plate 8 away from the drain pipe 1. A third telescopic rod 35 is fixed between the second transmission plate 8 and the second mounting plate 33. The telescopic direction of the third telescopic rod 35 is parallel to the sliding direction of the second transmission plate 8.

[0047] Reference Figure 3 and Figure 5A first accumulation box 15 is fixed to the side of the first transmission plate 7 near the drain pipe 1, with the opening of the first accumulation box 15 facing the drain pipe 1. One end of the first pull rope 10 near the first transmission plate 7 is connected to the first transmission plate 7 via a fixed connection to the first accumulation box 15. A first through hole 16 is formed in the bottom wall of the first accumulation box 15, penetrating the first transmission plate 7. A second accumulation box 17 is fixed to the side of the second transmission plate 8 near the drain pipe 1, with the opening of the second accumulation box 17 facing towards the drain pipe 1. A second pull rope 11 is located near the second transmission plate 8. One end of plate 8 is connected to the second transmission plate 8 by being fixed to the second accumulation box 17. The bottom wall of the second accumulation box 17 has a second through hole 18, which passes through the second transmission plate 8. The diameter of the first through hole 16 and the second through hole 18 is equal to 1.5mm. The end of the connecting rope 6 away from the sliding rod 3 moves through the bent pipe 20 and is fixed to the first accumulation box 15. The connecting rope 6 is connected to the first transmission plate 7 by being fixed to the first accumulation box 15. The guide plate 9 is located above the second accumulation box 17, and the rotation axis of the guide plate 9 is perpendicular to the length of the connecting pipe 5. Direction: The guide plate 9 is used to block the first transmission plate 7 or the second transmission plate 8. The end of the first pull rope 10 away from the first accumulation box 15 is fixedly set on the side of the guide plate 9 near the first accumulation box 15. The end of the second pull rope 11 away from the second accumulation box 17 is fixedly set on the side of the guide plate 9 near the second accumulation box 17. The first spring 12 is movably sleeved on the second telescopic rod 34. The first spring 12 is used to push the first transmission plate 7 to slide towards the drain pipe 1. One end of the first spring 12 is fixedly connected to the first mounting plate 32, and the other end is fixed... The second spring 13 is movably sleeved on the third telescopic rod 35 and is fixedly connected to the side of the first transmission plate 7 away from the first accumulation box 15. The second spring 13 is used to push the second transmission plate 8 to slide towards the drain pipe 1. One end of the second spring 13 is fixedly connected to the second mounting plate 33, and the other end is fixedly connected to the side of the second transmission plate 8 away from the second accumulation box 17. When there is no groundwater in either the first accumulation box 15 or the second accumulation box 17, the guide plate 9 is tilted upward towards the direction away from the first accumulation box 15 to block the second accumulation box 17.

[0048] When groundwater seeps into the drain pipe 1 and flows into the connecting pipe 5 through the bend 20, it first flows into the first accumulation box 15. Because the diameter of the first through hole 16 is small, the amount of water flowing into the first accumulation box 15 is greater than the amount flowing out of the first through hole 16. As the amount of groundwater in the first accumulation box 15 increases, it drives the first accumulation box 15 to slide away from the drain pipe 1, compressing the first spring 12. At this time, the first pull rope 10 pulls the guide plate 9 to rotate towards the first accumulation box 15, and the second pull rope 11 pulls the second accumulation box 17 to move a certain distance towards the drain pipe 1. The connecting rope 6 pulls the sliding rod 3 to move a certain distance towards the bend 20, causing the sliding rod 3 to move the unblocking rod 4. At this time, the guide plate 9 blocks the first accumulation box 15, allowing the groundwater flowing into the connecting pipe 5 from the bend 20 to flow into the second accumulation box 17 under the guidance of the guide plate 9. The increase in water volume in the second accumulation box 17 and the decrease in water volume in the first accumulation box 15 cause the second accumulation box 17 to gradually move away from the drain pipe 1, compressing the second spring 13. The first accumulation box 15 slides towards the drain pipe 1, at which point the tension of the first accumulation box 15 on the connecting rope 6 decreases. Under the tension of the tension spring 14 and the gravity of the sliding rod 3, the sliding rod 3 moves away from the connecting pipe 5, causing the unblocking rod 4 to move in the opposite direction at the corresponding drain hole 2. At this time, the second pull rope 11 pulls the guide plate 9 to rotate towards the second accumulation box 17, opening the first accumulation box 15 and covering the second accumulation box 17. The groundwater flowing into the connecting pipe 5 continues to enter the first accumulation box 15. This process repeats, realizing the reciprocating movement of the sliding rod 3, allowing the unblocking rod 4 to vibrate reciprocally within the corresponding drain hole 2, making it less likely for soil to clog the holes and ensuring drainage efficiency to a certain extent.

[0049] Reference Figure 3 and Figure 4 Multiple forked rods 19 are fixedly arranged circumferentially on the side of the unblocking rod 4 near the drain hole 2. In this embodiment, four forked rods 19 are spaced apart circumferentially along the unblocking rod 4. The forked rods 19 are located on the side of the sealing plug 24 near the sliding rod 3. The distance from the end of the forked rod 19 away from the unblocking rod 4 to the center of the unblocking rod 4 is less than the radius of the drain hole 2, allowing the forked rods 19 to enter the drain hole 2. The forked rods 19 are offset from the limiting rod 31. When the unblocking rod 4 reciprocates within the drain hole 2, it drives the forked rods 19 to move, which helps to improve the unblocking effect of the drain hole 2, thereby further ensuring drainage efficiency.

[0050] Reference Figure 3 and Figure 4 The sealing plug 24 has a water inlet groove 29 on the side near the unblocking rod 4. The water inlet groove 29 extends to the position of the unblocking rod 4, which helps to allow groundwater to enter the drain hole 2 through the water inlet groove 29, reducing the possibility of blocking the drain pipe 1 when the sealing plug 24 is located outside the drain pipe 1.

[0051] The implementation principle of this application embodiment is as follows: During construction, the drain pipe 1 is first placed in the water tank. At this time, the air bladder 21 is in a deflated state, and the sealing plug 24 is located outside the sliding rod 3, so that the drain pipe 1 is filled with water. Then, the opening and closing valve 23 is opened, and air is supplied into the inflation pipe 22 using an external tool. The air bladder 21 expands and pushes the sliding rod 3 to move away from the connecting pipe 5, compressing the tension spring 14, so that the sliding rod 3 drives the unblocking rod 4 to slide closer to the drain pipe 1. The sealing plug 24 seals the drain hole 2. At this time, the air bladder 21 is filled. The opening and closing valve 23 is closed, and then the valve 25 on the connecting pipe 5 is closed, thereby forming a siphon.

[0052] Then, insert the drain pipe 1 into a suitable position on the slope, install the air pump 26 on the slope, connect the air supply pipe 27 to the inflation connector 22 through the delivery pipe 28, and then connect the connecting pipe 5 to the converging pipe; next, open the on / off valve 23, start the air pump 26, so that the air pump 26 extracts the gas from the airbag 21 through the air supply pipe 27 and the delivery pipe 28. At this time, the airbag 21 deflates, causing the sliding rod 3 to move towards the connecting pipe 5, causing the tension spring 14 to stretch, and the unblocking rod 4 to push the sealing plug 24 away from the drain pipe 1, so that the sealing plug... 24. Remove the drain pipe 1, and at the same time, create a negative pressure in the bend 20. At this time, the drain pipe 1 actively draws in the groundwater in the slope, forming an active water suction phenomenon. Then, open the valve 25, and the groundwater can flow into the connecting pipe 5 along the bend 20, and then be discharged into the drainage ditch from the converging pipe. Then, start the air pump 26 to fill the air inlet pipe 22 with an appropriate amount of gas, so that the tension spring 14 pulls the sliding rod 3 to move a certain distance away from the connecting pipe 5. At this time, the tension spring 14 is in a natural state, and there is still space in the air bag 21, which can meet the reciprocating sliding of the sliding rod 3.

[0053] The groundwater flowing into the connecting pipe 5 first flows towards the first accumulation box 15. As the amount of groundwater in the first accumulation box 15 increases, it drives the first accumulation box 15 to slide away from the drain pipe 1, compressing the first spring 12. At this time, the first pull rope 10 pulls the guide plate 9 to rotate towards the first accumulation box 15, and the connecting rope 6 pulls the sliding rod 3 to move a certain distance towards the bend 20, causing the sliding rod 3 to move the unblocking rod 4. At this time, the guide plate 9 blocks the first accumulation box 15, causing the groundwater flowing into the connecting pipe 5 at the bend 20 to flow into the second accumulation box 17 under the guidance of the guide plate 9. As the amount of water in the second accumulation box 17 increases and the amount of water in the first accumulation box 15 decreases, the second accumulation box 17 gradually moves away from the drain pipe 1. The sliding rod moves away from the drain pipe 1, compressing the second spring 13. The first accumulation box 15 slides towards the drain pipe 1, reducing the tension of the first accumulation box 15 on the connecting rope 6. Under the tension of the tension spring 14, the sliding rod 3 moves away from the connecting pipe 5, causing the unblocking rod 4 to move in the opposite direction within the corresponding drain hole 2. At this time, the second pull rope 11 pulls the guide plate 9 to rotate towards the second accumulation box 17, opening the first accumulation box 15 and covering the second accumulation box 17. The groundwater flowing into the connecting pipe 5 continues to enter the first accumulation box 15. This process repeats, enabling the sliding rod 3 to move back and forth, allowing the unblocking rod 4 to vibrate back and forth within the corresponding drain hole 2. This prevents the soil from clogging the holes and ensures drainage efficiency to a certain extent.

[0054] This application also discloses a construction method for the above-mentioned highway slope drainage structure. The construction method for the highway slope drainage structure includes the following steps:

[0055] Step 1: Place the drain pipe 1 into the pool. At this time, the sealing plug 24 is outside the drain pipe 1, allowing water to fill the drain pipe 1 through the drain hole 2. Then, open the on / off valve 23 and use an external tool to inflate the air inlet pipe 22, causing the airbag 21 to expand and push the sliding rod 3 to move away from the connecting pipe 5. This causes the unblocking rod 4 and the sealing plug 24 to slide closer to the drain pipe 1, sealing the drain hole 2 with the sealing plug 24. Then, close the on / off valve 23 and the valve 25. Finally, insert the drain pipe 1 into the preset position on the slope, causing the side of the drain pipe 1 closest to the slope to tilt downwards.

[0056] Step 2: Connect the connecting pipe 5 to the longitudinal converging pipe of the slope, install the air pump 26 on the slope, and connect the inflation pipe 22 to the air supply pipe 27 through the delivery pipe 28.

[0057] Step 3: Open the on / off valve 23 and start the air pump 26. The air pump 26 draws gas from the airbag 21 through the air supply pipe 27 and the delivery pipe 28, causing the airbag 21 to deflate. The airbag 21 drives the sliding rod 3 to slide towards the connecting pipe 5, causing the unblocking rod 4 to push the sealing plug 24 out of the drain hole 2. Then, open the valve 25, and the groundwater in the slope actively seeps into the drain pipe 1 through the drain hole 2, flows into the first accumulation box 15 of the connecting pipe 5 through the bend pipe 20, and then starts the air pump 26 to fill the inflation pipe 22 with a certain amount of gas. The tension spring 14 pulls the sliding rod 3 to move a certain distance away from the connecting pipe 5, so that the tension spring 14 is in its natural state. As the groundwater in the first accumulation box 15 increases, the first accumulation box 15 moves away from the drain pipe 1, compressing the first spring 12, pulling the connecting rope 6 and the first pull rope 10, so that the connecting rope 6 pulls the sliding rod 3 to move closer to the connecting pipe 5, driving the unblocking rod 4 to move in the drain hole 2. The first pull rope 10 pulls the guide plate 9 to rotate closer to the first accumulation box 15, blocking the first accumulation box 15.

[0058] Step 4: The groundwater entering the connecting pipe 5 flows into the second accumulation box 17 along the guide plate 9. As the groundwater in the second accumulation box 17 increases, the groundwater in the first accumulation box 15 decreases. The first spring 12 pushes the first accumulation box 15 to move closer to the drain pipe 1. The tension spring 14 pulls the sliding rod 3 to move away from the connecting pipe 5, thereby causing the sliding rod 3 to drive the unblocking rod 4 to move in the drain hole 2. The second accumulation box 17 gradually moves away from the drain pipe 1. The second pull rope 11 pulls the guide plate 9 to rotate towards the second accumulation box 17, blocking the second accumulation box 17 and opening the first accumulation box 15, allowing the groundwater to continue flowing into the first accumulation box 15. This process is repeated to achieve the purpose of the unblocking rod 4 vibrating back and forth in the drain hole 2.
