Abstract
Description
Technical Field
[0001] The present application relates to the technical field of slope protection, and in particular to a rail pile slope protection structure. Background Art
[0002] Rail piles are a type of anti-slide piles and are a commonly used reinforcement method in ground geotechnical engineering, especially in large landslide reinforcement and large open-pit mine side slope reinforcement. Rail piles are formed by placing rails in a borehole. When setting up rail piles, the old rails are placed in a pre-prepared borehole, and the bottom of the rails must face the thrust direction of the landslide. Compared with large-section reinforced concrete anti-slide piles, rail piles have the advantages of being light, flexible, and easy to construct. Therefore, they have been widely used in open-pit mine landslide prevention and control projects at home and abroad.
[0003] However, for some rock and soil slopes, due to the soft soil, even if rail piles are installed on the slopes, slope sliding is likely to occur on rainy days, thus causing adverse effects on the road surface next to the slope. Utility Model Content
[0004] In order to improve the stability of the slope and reduce the possibility of slope sliding, the present application provides a rail pile slope protection structure.
[0005] The present application provides a rail pile slope protection structure that adopts the following technical solution:
[0006] A rail pile slope protection structure comprises a plurality of anti-slip piles fixed on the bottom of the slope, a plurality of anti-slip piles are integrally formed with retaining walls, a plurality of stones are mixed in the retaining walls, and geogrids are arranged between adjacent anti-slip piles.
[0007] By adopting the above technical solution, by combining the rail anti-slide piles with the concrete retaining wall, the anti-slide piles can improve the fixing effect on the slope, and the retaining wall can block the sliding soil on the slope, which can improve the stability of the slope on the one hand, and protect the road surface below the slope on the other hand. The geogrid between the two anti-slide piles can increase the contact area between the anti-slide piles and the stones, so that the solidification of the stones and the anti-slide piles is better, and the structural stability of the retaining wall is enhanced.
[0008] Optionally, the anti-slip piles are rail piles.
[0009] By adopting the above technical solution, rail piles are suitable for rock slopes with small landslide thrust and relatively intact rock mass. Compared with large-section reinforced concrete anti-slide piles, rail piles have the advantages of being light, flexible and easy to construct.
[0010] Optionally, a plurality of positioning rods are fixedly connected to the side walls of the anti-slip piles, the geogrid is inserted into the positioning rods, abutment plates are slidably provided on the positioning rods, and locking members are provided on the positioning rods for pressing the abutment plates against the anti-slip piles.
[0011] By adopting the above technical solution, the geogrid is inserted into the positioning rod, which can reduce the position deviation of the geogrid during the casting process of the retaining wall. At the same time, the abutment plate is slid on the positioning rod until it is tightly against the anti-slip pile, and the geogrid is between the abutment plate and the anti-slip pile, thereby further fixing the geogrid, and then the abutment plate is fixed with a locking piece.
[0012] Optionally, a ring groove is formed on the positioning rod, and the locking member includes a plurality of blocking rings forming a ring shape, a telescopic member is fixedly connected between adjacent blocking rings, and a locking claw facing the direction of the anti-slip pile is fixedly connected to the blocking ring.
[0013] By adopting the above technical solution, the blocking ring is slid on the positioning rod toward the direction of the anti-slip pile, so that the locking claw abuts against the abutment plate until the blocking ring slides into the annular groove. The elastic member contracts so that the blocking ring is clamped in the annular groove. At this time, the end of the locking claw gradually extends toward the surrounding areas of the abutment plate, thereby increasing the contact area between the locking claw and the abutment plate and improving the tightening effect of the locking claw on the abutment plate.
[0014] Optionally, one end of the anti-slip pile inserted into the soil layer is fixedly connected to a support base, and the surface area of the support base is larger than the cross-sectional area of the anti-slip pile.
[0015] By adopting the above technical solution, the support base can increase the end area of the anti-slip pile, making it difficult for the anti-slip pile to be pulled out of the soil. At the same time, the support base can be consolidated with the underground soil, further enhancing the stability of the anti-slip pile.
[0016] Optionally, a plurality of drainage pipes penetrating both sides of the retaining wall are inserted into the retaining wall.
[0017] By adopting the above technical solution, the drainage pipe can drain the moisture in the slope soil, reducing the possibility of slope landslide.
[0018] Optionally, a drainage ditch is provided at one end of the retaining wall away from the slope.
[0019] By adopting the above technical solution, the drainage ditch can collect and drain the water discharged from the drainage pipe, reducing the water flowing onto the road surface and causing the road surface to be slippery.
[0020] Optionally, two rows of anti-slide piles are arranged in the retaining wall, and the spacing between adjacent anti-slide piles is 1 m.
[0021] By adopting the above technical solution, the two rows of anti-slip piles can improve the fixing effect on the retaining wall and improve the anti-slip ability of the retaining wall.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. By combining rail anti-slip piles with concrete retaining walls, the anti-slip piles can improve the fixing effect on the slope, and the retaining wall can block the sliding soil on the slope, which can improve the stability of the slope on the one hand, and protect the road surface below the slope on the other hand. The geogrid between the two anti-slip piles can increase the contact area between the anti-slip piles and the stones, thereby making the solidification of the stones and the anti-slip piles better and enhancing the structural stability of the retaining wall;
[0024] 2. Inserting the geogrid on the positioning rod can reduce the position deviation of the geogrid during the pouring process of the retaining wall. At the same time, slide the abutment plate on the positioning rod until it is tightly against the anti-slip pile, and the geogrid is between the abutment plate and the anti-slip pile, so as to further fix the geogrid, and then fix the abutment plate with a locking piece;
[0025] 3. Slide the blocking ring on the positioning rod toward the direction of the anti-slip pile so that the locking claw abuts against the abutment plate until the blocking ring slides into the annular groove. The elastic member contracts so that the blocking ring is clamped in the annular groove. At this time, the end of the locking claw gradually extends toward the surrounding of the abutment plate, thereby increasing the contact area between the locking claw and the abutment plate and improving the tightening effect of the locking claw on the abutment plate.

[0031] The following is combined with Figure 1-4 This application is described in further detail.
[0032] The present application embodiment discloses a rail pile slope protection structure, referring to Figure 1 and Figure 2 , including several rows of anti-slip piles 2 fixed on the slope 1. In this embodiment, the anti-slip piles 2 are arranged in two rows and staggered, and the spacing between the anti-slip piles 2 is 1m*1m, and the anti-slip piles 2 are rail piles. One end of the anti-slip pile 2 inserted into the soil layer of the slope 1 is fixedly connected with a support base 5, and the support base 5 is made of concrete, and the surface area of the support base 5 is larger than the cross-sectional area of the anti-slip pile 2. The support base 5 is made of concrete material, which can better fix with the soil, thereby enhancing the fixing effect of the anti-slip pile 2 in the slope 1. At the same time, the support base 5 can increase the end area of the anti-slip pile 2, so that the anti-slip pile 2 is not easy to be pulled out of the soil, further enhancing the stability of the anti-slip pile 2.
[0033] Reference Figure 2 and Figure 3 The retaining wall 3 is cast at one end of the anti-slide pile 2 extending out of the soil. The retaining wall 3 includes a plurality of geogrids 32. The two ends of each geogrid 32 are respectively fixed on the adjacent anti-slide pile 2, which increases the contact area between the anti-slide pile 2 and the stone 31, thereby improving the connection stability between the retaining wall 3 and the anti-slide pile 2. The geogrid 32 is connected in sections, which can increase the deformation of the geogrid 32, reduce the gaps between the irregular stones 31, and further enhance the stability of the retaining wall 3 structure.
[0034] Reference Figure 2 and Figure 4 A plurality of positioning rods 21 are fixedly connected to the side walls of the anti-slip pile 2 extending above the soil surface, and the geogrid 32 is inserted into the positioning rod 21. An abutment plate 22 is slidably provided on the positioning rod 21. The positioning rod 21 is provided with a locking piece 4 for fixing the abutment plate 22. The abutment plate 22 can press the geogrid 32 against the side wall of the anti-slip pile 2, thereby fixing the geogrid 32 between the abutment plate 22 and the anti-slip pile 2, which can reduce the position displacement of the geogrid 32 during the casting process of the retaining wall 3.
[0035] Reference Figure 4 A ring groove 211 is provided on the positioning rod 21, and the locking member 4 includes a plurality of blocking rings 41 slidably arranged on the positioning rod 21, and the plurality of blocking rings 41 are combined into a ring shape, and telescopic members are fixedly connected between adjacent blocking rings 41, and the telescopic members are springs. A plurality of locking claws 43 are fixedly connected to one end of the blocking ring 41 facing the anti-slip pile 2. When the blocking ring 41 is moved toward the anti-slip pile 2, the end of the locking claw 43 is pressed against the abutment plate 22, thereby pressing the abutment plate 22 against the side wall of the anti-slip pile 2.
[0036] When the blocking ring 41 slides toward the annular groove 211, the end of the locking claw 43 gradually extends toward the periphery of the abutment plate 22, so that the contact area between the locking claw 43 and the abutment plate 22 increases, thereby improving the abutment effect of the locking claw 43 on the abutment plate 22. When the blocking ring 41 moves into the annular groove 211, the elastic member 42 contracts to tighten the adjacent blocking ring 41, so that the blocking ring 41 is clamped in the annular groove 211, and the blocking ring 41 is not easy to slip on the positioning rod 21, ensuring that the thrust of the blocking ring 41 on the locking claw 43 is clamped.
[0037] Reference Figure 1 A plurality of drainage pipes 6 penetrating both sides of the retaining wall 3 are inserted into the retaining wall 3 , and a drainage ditch 7 is arranged at one end of the retaining wall 3 away from the slope 1 .
[0038] The drainage pipe 6 can drain the moisture in the soil of the slope 1, reducing the possibility of landslides in the slope 1. The drainage ditch 7 can collect and drain the moisture discharged from the drainage pipe 6, reducing the water flowing onto the road surface and causing the road surface to be slippery.
[0039] The implementation principle of a rail pile slope protection structure in the embodiment of the present application is as follows: first, a hole is drilled on the slope 1, and the anti-slip pile 2 is inserted into the hole, and a support base 5 is cast at the bottom of the hole so that the support base 5 is consolidated with the soil at the bottom of the hole, and then the hole is covered with soil. The geogrid 32 is inserted into the positioning rod 21, and an abutment plate 22 is inserted into the positioning rod 21, and then the locking member 4 is sleeved on the positioning rod 21, and a blocking ring 41 is slid on the positioning rod 21 toward the direction of the anti-slip pile 2, so that the locking claw 43 abuts against the abutment plate 22 until the blocking ring 41 slides into the annular groove 211. A drainage pipe 6 is inserted into the template, and then the stone 31 concrete is poured into the template to form a retaining wall 3.
[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
