A method and equipment for treating water damage to asphalt pavements

Abstract

This invention provides a method and equipment for treating water damage to asphalt pavements, belonging to the field of highway maintenance and repair technology. It includes multiple connecting frames, each comprising a first horizontal pipe with end caps fixedly fitted to both ends. A first vertical pipe is fixedly connected to each end cap. Multiple first limiting components for limiting the perforated double-walled corrugated pipe are installed on the first horizontal pipe. By setting up connecting frames and second limiting components, during the backfilling of crushed stone, the crushed stone impacts an arc-shaped plate and accumulates on it. The force on the arc-shaped plate causes the sliding sleeve to descend via the first connecting pipe, and the first limiting box to descend via the second connecting pipe. The rubber pad inside the first limiting box presses the geotextile against the bottom of the T-shaped groove shoulder, preventing the geotextile from being displaced or pressed into the groove by the crushed stone impact, ensuring the normal use of the geotextile, reducing adverse effects on the construction process, and ensuring construction speed.

Description

Technical Field

[0001] This invention relates to the field of highway maintenance and repair technology, and in particular to a method and equipment for treating water damage to asphalt pavements. Background Technology

[0002] Currently, water damage to asphalt pavements is widespread, severely reducing their performance and shortening their lifespan, resulting in significant economic losses and negative social impacts. However, in practice, the common practice of milling and overlaying to address water damage often fails to eliminate interlayer water retention, leading to recurrence of water damage and other defects shortly after repair.

[0003] To drain interlayer water and improve the service life of asphalt pavement after treatment, existing technologies use on-site core drilling or exploratory pit excavation to determine the extent of water damage and the location of interlayer water. Treatment involves trenching along the road's cross slope, determining the trench depth based on the water location, installing perforated double-walled corrugated pipes within the trench, backfilling with crushed stone and compacting it, wrapping the trench walls with geotextile, and restoring the asphalt surface layer to its original structure. While this method effectively drains interlayer water, the geotextile wrapping the trench walls is susceptible to displacement during crushed stone backfilling, sometimes even detaching from the trench walls and being pressed into the trench by the crushed stone. This affects the normal use of the geotextile, and the geotextile pressed into the trench is difficult to remove under the weight of the crushed stone, potentially impacting the construction process and reducing construction speed. Therefore, this application provides a method and equipment for treating water damage to asphalt pavement to meet this need. Summary of the Invention

[0004] The technical problem to be solved by this invention is to provide a method and equipment for treating water damage to asphalt pavements. This addresses the problem that while existing methods for treating water damage to asphalt pavements can effectively drain interlayer water, the geotextile wrapped around the trench wall is easily impacted by the crushed stone during backfilling, causing displacement, and in severe cases, even detaching from the trench wall and being pressed into the trench by the crushed stone. This affects the normal use of the geotextile, and the geotextile pressed into the trench is difficult to remove under the heavy pressure of the crushed stone, which can affect the construction process and reduce the construction speed.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A method for treating water damage to asphalt pavements includes the following steps:

[0007] S1: Determine the extent of water damage and the location of interlayer water stagnation by drilling cores or excavating test pits on the roadbed, and open T-shaped trenches along the cross slope of the road.

[0008] S2: A concrete pad is laid at the bottom of the T-shaped channel. A geotextile covering the top of the concrete pad and the sidewalls of the T-shaped channel is laid inside the T-shaped channel with the concrete pad. A perforated double-wall corrugated pipe is placed at the bottom of the geotextile. The connecting frame is placed into the T-shaped channel, and the multiple perforated double-wall corrugated pipes in the T-shaped channel are separated and limited by the first limiting component on the connecting frame.

[0009] S3: Backfill the T-shaped groove where the geotextile is laid with crushed stone. During the backfilling process, the crushed stone will impact the arc plate. The arc plate is driven by the sliding sleeve and the second connecting pipe to move the first limit box, and by the connecting rod to move the second limit box. The rubber pad in the first limit box presses the geotextile tightly, and the rubber pad in the second limit box abuts against the shoulder of the T-shaped groove to prevent the geotextile and the perforated double-wall corrugated pipe from shifting during the crushed stone backfilling process.

[0010] S4: After the crushed stone layer is filled, the concrete cover layer, the first asphalt surface layer, and the second asphalt surface layer are filled on top of the crushed stone layer in sequence.

[0011] An asphalt pavement water damage treatment device, applying the aforementioned asphalt pavement water damage treatment method, includes multiple connecting frames. Each connecting frame includes a first horizontal pipe, with end caps fixedly fitted to both ends of the first horizontal pipe. A first vertical pipe is fixedly connected to each end cap. Multiple first limiting components for limiting the perforated double-walled corrugated pipe are installed on the first horizontal pipe. Second limiting components for limiting the geotextile are installed on the first vertical pipe. The second limiting components include a fixing ring fixedly fitted to the first vertical pipe, a sliding sleeve slidably fitted to the first vertical pipe, and a spring sleeve fixedly connected to the fixing ring and fitted to the first vertical pipe. A spring is provided, with one end of the spring away from the fixed ring fixedly connected to the sliding sleeve. A first connecting tube is fixedly connected to the side of the two sliding sleeves that are close to each other. A rubber pad is rotatably sleeved on the first connecting tube. A second connecting tube is fixedly connected to the side of the two sliding sleeves that are far from each other. A first limiting box is fixedly connected to the second connecting tube. Two connecting rods are rotatably connected to the second connecting tube. A second limiting box is rotatably connected to the end of the two connecting rods that is far from the second connecting tube. A rubber pad is fixedly sleeved inside both the first limiting box and the second limiting box. An arc-shaped plate is rotatably sleeved on the first connecting tube.

[0012] Preferably, the top of the sliding sleeve is closed.

[0013] Preferably, the retaining ring is located inside the sliding sleeve.

[0014] Preferably, the center of the arc-shaped plate is concave, and the bottom of the arc-shaped plate is higher than the top of the crushed stone layer.

[0015] Preferably, the arc-shaped plate is located at the middle position of the first connecting pipe.

[0016] Preferably, the first limiting component includes multiple sets of first limiting sleeves fixedly sleeved on the first horizontal tube. Each set of first limiting sleeves includes two first limiting sleeves. A second vertical tube is fixedly connected to the first limiting sleeve. The two second vertical tubes in the same set abut against both sides of the double-walled corrugated pipe with the same opening. A support tube is fixedly connected to the end of the second vertical tube away from the first limiting sleeve.

[0017] Preferably, reinforcing ribs are fixedly connected at the connection points of the second vertical pipe and the support pipe.

[0018] Preferably, the bottom of the first horizontal tube has a flat surface, and the first limiting sleeve is adapted to the first horizontal tube.

[0019] Preferably, the bottom of the end cap and the first limiting sleeve are both connected by fastening bolts through threads, and the fastening bolts penetrate the end cap or the first limiting sleeve and abut against the plane.

[0020] Compared with the prior art, the present invention has at least the following beneficial effects:

[0021] In the above scheme, by setting up a connecting frame and a second limiting component, during the backfilling of crushed stone, the crushed stone impacts the arc-shaped plate and accumulates on the arc-shaped plate. The arc-shaped plate, under the force, drives the sliding sleeve to descend through the first connecting pipe, and drives the first limiting box to descend through the second connecting pipe. The rubber pad inside the first limiting box presses the geotextile against the bottom of the T-shaped groove shoulder, preventing the geotextile from being impacted by the crushed stone, causing displacement or being pressed into the groove by the crushed stone, ensuring the normal use of the geotextile, reducing the adverse impact on the construction process, and ensuring the construction speed.

[0022] By incorporating connecting rods, second limiting boxes, and rubber pads, the descending first connecting pipe, through two sliding sleeves, two second connecting pipes, and two connecting rods, causes the two second limiting boxes to move away from each other at the bottom of the T-shaped groove shoulder. The rubber pads within the second limiting boxes also contact the T-shaped groove shoulder, preventing lateral movement of the second limiting components due to gravel impact, thus avoiding geotextile displacement and further ensuring the geotextile's stability. Furthermore, during use, the more gravel falls into the T-shaped groove, the greater the pressure exerted by the rubber pads in the first and second limiting boxes on the bottom and shoulder of the T-shaped groove shoulder, resulting in better geotextile positioning. After filling with gravel, the arc-shaped plate can be flipped over to dump the accumulated gravel into the T-shaped groove, allowing the sliding sleeves to reset under spring support. This eliminates the contact between the rubber pads in the first and second limiting boxes and the geotextile and the bottom and shoulder of the T-shaped groove shoulder, facilitating the removal of the device from the gravel layer. The device is ingeniously designed and easy to use.

[0023] By setting up a concrete subbase, geotextile, perforated double-walled corrugated pipe, crushed stone layer, concrete cover layer, first asphalt surface layer, and second asphalt surface layer, the water-sealing is transformed into water-draining, which can effectively remove water stuck between layers and greatly improve the service life of the pavement structure. The concrete cover layer and the first and second asphalt surface layers are overlapped in a stepped manner, which greatly improves the overall performance of the structure and prevents the generation of radial cracks.

[0024] By setting a first limiting component, the support effect is provided by the contact between the support pipe and the bottom of the geotextile. Multiple sets of second vertical pipes separate and limit the adjacent perforated double-wall corrugated pipes, so as to prevent the perforated double-wall corrugated pipes from sticking together under the pressure of the crushed stone after the crushed stone layer is filled, blocking the holes on the surface of the perforated double-wall corrugated pipes and affecting their use.

[0025] By creating a flat surface, the connection stability of the first horizontal tube, end cap, and first limiting component is improved, and the end cap and first limiting component are prevented from deflecting due to the impact of gravel after being fixed, which would affect the stability of the first limiting component in use.

[0041] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a method for treating water damage to asphalt pavement, comprising the following steps:

[0042] S1: Determine the extent of water damage and the location of interlayer water stagnation by drilling cores or excavating test pits on the roadbed 1 on site, and open T-shaped trenches 2 along the cross slope of the road.

[0043] S2: A concrete pad 3 is laid at the bottom of the T-shaped channel 2. A geotextile 4 is laid inside the T-shaped channel 2 with the concrete pad 3, covering the top of the concrete pad 3 and the side wall of the T-shaped channel 2. A perforated double-wall corrugated pipe 5 is placed at the bottom of the geotextile 4. The connecting frame 10 is placed inside the T-shaped channel 2, and the multiple perforated double-wall corrugated pipes 5 inside the T-shaped channel 2 are separated and limited by the first limiting component 14 on the connecting frame 10.

[0044] S3: Backfill crushed stone into the T-shaped groove 2 where the geotextile 4 is laid. During the backfilling process, the crushed stone will impact the arc plate 31. The arc plate 31 is driven by the sliding sleeve 23 and the second connecting pipe 26 to move the first limiting box 27, and by the connecting rod 28 to move the second limiting box 29. The rubber pad 30 in the first limiting box 27 presses the geotextile 4, and the rubber pad 30 in the second limiting box 29 abuts against the shoulder of the T-shaped groove 2 to prevent the geotextile 4 and the perforated double-wall corrugated pipe 5 from shifting during the crushed stone backfilling process.

[0045] S4: After the crushed stone layer 6 is filled, the concrete cover layer 7, the first asphalt surface layer 8, and the second asphalt surface layer 9 are sequentially filled on top of the crushed stone layer 6.

[0046] By setting up a concrete subbase 3, geotextile 4, perforated double-walled corrugated pipe 5, crushed stone layer 6, concrete cover 7, first asphalt surface layer 8, and second asphalt surface layer 9, the water-sealing is transformed into water-draining, which can effectively remove water stuck between layers and greatly improve the service life of the pavement structure. The concrete cover 7 and the first asphalt surface layer 8 and the second asphalt surface layer 9 are overlapped in a stepped manner, which greatly improves the overall performance of the structure and prevents the generation of radial cracks.

[0047] like Figure 3-6 As shown, an embodiment of the present invention also provides an asphalt pavement water damage treatment device, which applies an asphalt pavement water damage treatment method, including multiple connecting frames 10. Each connecting frame 10 includes a first horizontal pipe 11, with end caps 12 fixedly sleeved at both ends of the first horizontal pipe 11. A first vertical pipe 13 is fixedly connected to the end caps 12. Multiple first limiting components 14 for limiting and separating multiple perforated double-wall corrugated pipes 5 are installed on the first horizontal pipe 11. There can be one or more perforated double-wall corrugated pipes 5. A second limiting component 15 for limiting geotextile 4 is installed on the first vertical pipe 13. The second limiting component 15 includes a fixing ring 22 fixedly sleeved on the first vertical pipe 13, a sliding sleeve 23 slidably sleeved on the first vertical pipe 13, and a fixed ring 22 fixedly sleeved on the first vertical pipe 13. A spring 24 is on tube 13. The end of spring 24 away from fixed ring 22 is fixedly connected to sliding sleeve 23. A first connecting tube 25 is fixedly connected to the side of the two sliding sleeves 23 that are close to each other. A rubber pad 30 is rotatably sleeved on the first connecting tube 25. A second connecting tube 26 is fixedly connected to the side of the two sliding sleeves 23 that are far from each other. A first limiting box 27 is fixedly connected to the second connecting tube 26. Two connecting rods 28 are rotatably connected to the second connecting tube 26. The end of the connecting rod 28 away from the second connecting tube 26 is tilted downward in the normal state. A second limiting box 29 is rotatably connected to the end of the two connecting rods 28 away from the second connecting tube 26. A rubber pad 30 is fixedly sleeved inside the first limiting box 27 and the second limiting box 29. An arc plate 31 is rotatably sleeved on the first connecting tube 25.

[0048] After laying the concrete pad 3 and geotextile 4 in the T-groove 2 by setting up connecting frames 10 and second limiting components 15, the perforated double-wall corrugated pipe 5 is placed into the T-groove 2 covered with geotextile 4. Multiple connecting frames 10 equipped with first limiting components 14 and second limiting components 15 are evenly arranged in the T-groove 2. The perforated double-wall corrugated pipe 5 in the T-groove 2 is separated and limited by the first limiting components 14. Then, crushed stone is backfilled into the T-groove 2. During this process, the crushed stone impacts the arc-shaped plate. 31 and accumulate on the arc plate 31. The arc plate 31 is subjected to force, which drives the sliding sleeve 23 to descend and compress the spring 24 through the first connecting pipe 25, and drives the first limiting box 27 to descend through the second connecting pipe 26. The rubber pad 30 in the first limiting box 27 presses the geotextile 4 under the contact of the bottom of the shoulder of the T-shaped groove 2, so as to prevent the geotextile 4 from being impacted by gravel, causing displacement or being pressed into the groove by gravel, ensuring the normal use of the geotextile 4, reducing the adverse impact on the construction process, and ensuring the construction speed.

[0049] By setting up connecting rod 28, second limiting box 29, and rubber pad 30, the descending first connecting pipe 25 also drives the two second limiting boxes 29 to move away from each other at the bottom of the shoulder side of the T-groove 2 through two sliding sleeves 23, two second connecting pipes 26, and two connecting rods 28. The rubber pad 30 inside the second limiting box 29 abuts against the shoulder side of the T-groove 2, preventing the second limiting component 15 from shifting laterally due to the impact of gravel, thus ensuring the stability of the geotextile 4. Simultaneously, during use, when gravel falls into the T-groove 2... The more stones there are, the greater the squeezing force of the rubber pads 30 in the first limiting box 27 and the second limiting box 29 on the bottom and shoulder of the T-shaped groove 2, and the better the limiting effect on the geotextile 4. After the crushed stone is filled, the arc plate 31 can be flipped over to pour the crushed stone accumulated in the arc plate 31 into the T-shaped groove 2, so that the sliding sleeve 23 is reset under the elastic support of the spring 24, and the contact between the rubber pads 30 in the first limiting box 27 and the second limiting box 29 and the bottom and shoulder of the geotextile 4 and the T-shaped groove 2 is eliminated, making it easy for this device to be removed from the crushed stone layer 6. The structure is ingenious and easy to use.

[0050] like Figure 6 As shown, in this embodiment, the top of the sliding sleeve 23 is closed to prevent a large amount of dust generated during the dumping of gravel from entering the gap between the sliding sleeve 23 and the first vertical pipe 13 through the top of the sliding sleeve 23, thereby increasing the wear generated during the sliding of the sliding sleeve 23 and affecting the service life of the sliding sleeve 23.

[0051] like Figure 6As shown, in this embodiment, the fixing ring 22 is located inside the sliding sleeve 23 to prevent gravel from entering the sliding sleeve 23 through the gap between the fixing ring 22 and the sliding sleeve 23, getting stuck between the fixing ring 22 and the sliding sleeve 23, affecting the normal use of the sliding sleeve 23, and ensuring the stability of the sliding sleeve 23 in use.

[0052] like Figure 5 As shown, in this embodiment, the middle part of the arc-shaped plate 31 is concave, and the bottom of the arc-shaped plate 31 is higher than the top of the crushed stone layer 6. The arc-shaped plate 31 is located at the middle position of the first connecting pipe 25. The concave arc-shaped plate 31 guides the crushed stone falling on the arc-shaped plate 31, making it easier for the crushed stone to accumulate on the arc-shaped plate 31 and improving the utilization effect of the crushed stone. The arc-shaped plate 31, which is higher than the top of the crushed stone layer 6 by a preset value, avoids the arc-shaped plate 31 being piled up in the crushed stone layer 6 after the filling of the crushed stone layer 6 is completed, thus avoiding increasing the operation difficulty of the arc-shaped plate 31 and ensuring the operation convenience of the arc-shaped plate 31.

[0053] like Figure 4 and Figure 5 As shown, in this embodiment, the first limiting component 14 includes multiple sets of first limiting sleeves 17 fixedly sleeved on the first horizontal tube 11. Each set of first limiting sleeves 17 includes two first limiting sleeves 17. A second vertical tube 18 is fixedly connected to the first limiting sleeve 17. The two second vertical tubes 18 in the same set abut against the two sides of the double-walled corrugated pipe 5 with the same opening. A support tube 19 is fixedly connected to the end of the second vertical tube 18 away from the first limiting sleeve 17.

[0054] By setting the first limiting component 14, the support effect is provided by the contact between the support pipe 19 and the bottom of the geotextile 4. Multiple sets of second vertical pipes 18 separate and limit the adjacent perforated double-wall corrugated pipes 5, so as to prevent the perforated double-wall corrugated pipes 5 from sticking together under the pressure of the crushed stone layer 6 after the filling is completed, blocking the holes on the surface of the perforated double-wall corrugated pipes 5 and affecting the use of the perforated double-wall corrugated pipes 5.

[0055] like Figure 5 As shown, in this embodiment, reinforcing ribs 20 are fixedly connected at the connection positions of the second vertical pipe 18 and the support pipe 19. By setting the reinforcing ribs 20, the support strength at the connection positions of the second vertical pipe 18 and the support pipe 19 is improved, thereby increasing the service life of the second vertical pipe 18 and the support pipe 19.

[0056] like Figure 5As shown, in this embodiment, the bottom of the first horizontal tube 11 is provided with a flat surface 16, and the first limiting sleeve 17 is adapted to the first horizontal tube 11. The bottom of the end cap 12 and the first limiting sleeve 17 are both connected by fastening bolts 21 through threads. The fastening bolts 21 penetrate the end cap 12 or the first limiting sleeve 17 and abut against the flat surface 16. By providing the flat surface 16, the connection stability of the first horizontal tube 11, the end cap 12, and the first limiting component 14 is improved, and the end cap 12 and the first limiting component 14 are prevented from deflecting due to the impact of gravel after being fixed, which would affect the stability of the first limiting component 14.

[0057] The technical solution provided by this invention, by setting up a concrete subbase, geotextile, perforated double-walled corrugated pipe, crushed stone layer, concrete cover layer, first asphalt surface layer, and second asphalt surface layer, transforms water sealing into water drainage, which can effectively remove water stuck between layers and greatly improve the service life of the pavement structure. The concrete cover layer and the first and second asphalt surface layers are overlapped in a stepped manner, which greatly improves the overall performance of the structure and prevents the generation of radial cracks.

[0058] By setting up connecting frames and second limiting components, after laying the concrete cushion layer and geotextile in the T-shaped groove, the perforated double-wall corrugated pipe is placed into the T-shaped groove covered with geotextile. Multiple connecting frames equipped with first and second limiting components are evenly arranged in the T-shaped groove. The first limiting component separates and limits the perforated double-wall corrugated pipe in the T-shaped groove. Then, crushed stone is backfilled into the T-shaped groove. During this process, the crushed stone impacts the arc plate and accumulates on the arc plate. The arc plate is stressed and drives the sliding sleeve to descend and compress the spring through the first connecting pipe. It also drives the first limiting box to descend through the second connecting pipe. The rubber pad in the first limiting box presses the geotextile tightly against the bottom of the shoulder of the T-shaped groove, preventing the geotextile from being impacted by the crushed stone, causing displacement, or being pressed into the groove by the crushed stone. This ensures the normal use of the geotextile, reduces the adverse impact on the construction process, and ensures the construction speed.

[0059] By incorporating connecting rods, second limiting boxes, and rubber pads, the descending first connecting pipe, through two sliding sleeves, two second connecting pipes, and two connecting rods, causes the two second limiting boxes to move away from each other at the bottom of the T-shaped groove shoulder. The rubber pads within the second limiting boxes also contact the T-shaped groove shoulder, preventing lateral movement of the second limiting components due to gravel impact, thus avoiding geotextile displacement and further ensuring the geotextile's stability. Furthermore, during use, the more gravel falls into the T-shaped groove, the greater the pressure exerted by the rubber pads in the first and second limiting boxes on the bottom and shoulder of the T-shaped groove shoulder, resulting in better geotextile positioning. After filling with gravel, the arc-shaped plate can be flipped over to dump the accumulated gravel into the T-shaped groove, allowing the sliding sleeves to reset under spring support. This eliminates the contact between the rubber pads in the first and second limiting boxes and the geotextile and the bottom and shoulder of the T-shaped groove shoulder, facilitating the removal of the device from the gravel layer. The device is ingeniously designed and easy to use.

[0060] By setting a first limiting component, the support effect is provided by the contact between the support pipe and the bottom of the geotextile. Multiple sets of second vertical pipes separate and limit the adjacent perforated double-wall corrugated pipes, so as to prevent the perforated double-wall corrugated pipes from sticking together under the pressure of the crushed stone after the crushed stone layer is filled, blocking the holes on the surface of the perforated double-wall corrugated pipes and affecting their use.

[0061] By creating a flat surface, the connection stability of the first horizontal tube, end cap, and first limiting component is improved, and the end cap and first limiting component are prevented from deflecting due to the impact of gravel after being fixed, which would affect the stability of the first limiting component in use.

The arc-shaped plate is subjected to force, which drives the sliding sleeve to descend through the first connecting pipe, and drives the first limiting box to descend through the second connecting pipe. The rubber pad inside the first limiting box presses the geotextile tightly against the bottom of the shoulder side of the T-shaped groove.

2. The asphalt pavement water damage control equipment according to claim 1, characterized in that, The top of the sliding sleeve is closed.

3. The asphalt pavement water damage control equipment according to claim 1, characterized in that, The retaining ring is located inside the sliding sleeve.

4. The asphalt pavement water damage control equipment according to claim 1, characterized in that, The center of the arc-shaped plate is concave, and the bottom of the arc-shaped plate is higher than the top of the gravel layer.

5. The asphalt pavement water damage control equipment according to claim 1, characterized in that, The arc-shaped plate is located at the middle of the first connecting pipe.

6. The asphalt pavement water damage control equipment according to claim 1, characterized in that, Reinforcing ribs are fixedly connected at the connection points of the second vertical pipe and the support pipe.

7. The asphalt pavement water damage control equipment according to claim 1, characterized in that, The bottom of the first horizontal tube has a flat surface, and the first limiting sleeve is adapted to the first horizontal tube.

8. The asphalt pavement water damage control equipment according to claim 7, characterized in that, The bottom of the end cap and the first limiting sleeve are both connected by fastening bolts through threads. The fastening bolts penetrate the end cap or the first limiting sleeve and abut against the plane.

9. A method for treating water damage to asphalt pavement, wherein the method uses the asphalt pavement water damage treatment equipment according to any one of claims 1-8, characterized in that, Includes the following steps: S1: Determine the extent of water damage and the location of interlayer water stagnation by drilling cores or excavating test pits on the roadbed, and open T-shaped trenches along the cross slope of the road. S2: A concrete pad is laid at the bottom of the T-shaped channel. A geotextile covering the top of the concrete pad and the sidewalls of the T-shaped channel is laid inside the T-shaped channel with the concrete pad. A perforated double-wall corrugated pipe is placed at the bottom of the geotextile. The connecting frame is placed into the T-shaped channel, and the multiple perforated double-wall corrugated pipes in the T-shaped channel are separated and limited by the first limiting component on the connecting frame. S3: Backfill the T-shaped groove where the geotextile is laid with crushed stone. During the backfilling process, the crushed stone will impact the arc plate. The arc plate drives the first limit box to move through the sliding sleeve and the second connecting pipe, and drives the second limit box to move through the connecting rod. The rubber pad in the first limit box presses the geotextile tightly, and the rubber pad in the second limit box abuts against the shoulder of the T-shaped groove to prevent the geotextile and the perforated double-wall corrugated pipe from shifting during the crushed stone backfilling process. S4: After the crushed stone layer is filled, the concrete cover layer, the first asphalt surface layer, and the second asphalt surface layer are filled on top of the crushed stone layer in sequence.
