[0029] Among them, Figure 1 A reference direction coordinate system for the embodiments of the present application is given. The following combines Figure 1 the directions shown to describe the embodiments of the present application.

[0030] The embodiments of the present application provide a slope support structure. Refer to Figures 1 to 4, including a plurality of retaining piles 100, drain pipes 200 and drainage pipes 300. The retaining piles 100 are arranged along the height direction, and the plurality of retaining piles 100 are arranged at intervals on the outer side of the slope; the drain pipes 200 are arranged along the height direction between adjacent retaining piles 100, and drain holes 210 are provided on the drain pipes 200; one end of the drainage pipe 300 is communicated with the drain pipe 200, and the other end of the drainage pipe 300 extends outward to the outer side of the slope.

[0031] The retaining piles 100 of the slope support structure play a supporting role, effectively enhancing the bearing capacity of the slope and preventing accidents such as landslides and collapses. The completed retaining piles 100 have long-term stability. By arranging a slope drainage structure formed by splicing the drainage pipe 300 and the drain pipe 200 between adjacent retaining piles 100, and the drain holes 210 on the drain pipe 200, the drain holes 210 are arranged in a plum blossom shape on the drain pipe 200. The water in the support structure enters the drain pipe 200 through the drain holes 210 and is discharged from the drainage pipe 300. The length of the drain pipe 200 changes with the height of the slope support, realizing all-round drainage. This slope support structure can be applied to permanent high slopes, is suitable for vertical support structures, and can solve the drainage problem of vertical slopes with relatively large heights.

[0032] In some embodiments, a filler 400 is provided between adjacent retaining piles 100, and the drainage pipe 300 is buried inside the filler 400. The filler 400 can block, and the filler 400 fills the gaps around the drain pipe 200. After filling, it can effectively fix the drain pipe 200. At the same time, the filler 400 is located outside the soil body between adjacent retaining piles 100 to prevent the loss of the soil body between adjacent retaining piles 100. It can be understood that the filler 400 can be sand, bricks, etc.

[0033] In some embodiments, a baffle 500 is provided on the outer side of the retaining pile 100, and the outer end of the drainage pipe 300 passes through the baffle 500, and the outer end of the drainage pipe 300 forms a drainage port 310. At present, the appearance of the permanent slope structure is poor. The baffle 500 covers the outer side of the retaining pile 100, improving the appearance of the support structure. Waist beams, capping beams, etc. can also be provided on the baffle 500 to decorate the appearance and improve the overall aesthetics. Moreover, the waist beam can enhance the integrity and stability of the support structure, transmit horizontal forces, and coordinate the deformation between the retaining piles 100. The capping beam can connect the retaining piles 100 into a whole, improve the stiffness of the support system, bear and transmit the horizontal and vertical forces from the pile tops of the retaining piles 100, and can also be used as a temporary support structure during the construction of the slope support structure. Specifically, the baffle 500 can be a cast-in-place structure or a precast structure.

[0034] For the supporting structure of a vertical slope with a relatively high height, it is necessary to consider the drainage inside the slope to reduce the lateral pressure of the soil mass and maintain the stability of the slope support. At the same time, the service life of the drainage device for the permanent slope support project also needs to be considered. In this application, the drain pipe 200 can be set to the same height as the slope support, and the drain pipe 200 is set perpendicular to the ground to ensure the drainage function. Moreover, the installation of the drain pipe 200 takes precedence over that of the baffle 500 to avoid making holes in the baffle 500 later. Since the post-sealed concrete slurry is prone to penetration, which may cause the blockage of the drain pipe 200 and a color difference with the slope surface, affecting the overall appearance, the baffle 500 is constructed later, which improves the stability of the overall slope and the drain pipe 200, and at the same time enhances the overall appearance of the permanent slope. Specifically, the drain pipe 200 is pre-embedded and installed between adjacent retaining piles 100, with better integrity and a better appearance of the permanent slope.

[0035] In some embodiments, the baffle 500 includes a cast-in-place concrete slab. The overall post-casting of the cast-in-place concrete slab improves the appearance quality of the permanent slope structure. A waterproof board 600 is provided between the baffle 500 and the filler 400. The waterproof board 600 is provided with through holes 610 for passing through the drain pipe 300. The waterproof board is an extruded polystyrene board. The waterproof board made of the extruded polystyrene board and the cast-in-place concrete slab together form an effective barrier. Specifically, the extruded polystyrene board can block the concrete slurry during the pouring of the cast-in-place concrete slab, preventing the concrete slurry during the pouring of the cast-in-place concrete slab from penetrating into the drain pipe 200. In other words, the extruded polystyrene board can prevent the post-poured concrete slurry from penetrating into the drain pipe 200 and avoid the blockage of the drain holes 210 or even the drain pipe 200.

[0036] Specifically, the cast-in-place concrete slab is a concrete slab formed by pouring concrete using a formwork. It is usually used in building structures, such as floor slabs, wall panels, etc. The cast-in-place concrete slab is made of concrete, has relatively high strength and load-bearing capacity, can provide good structural stability, and has good durability and can be used for a long time. Since concrete itself has good fire resistance, the cast-in-place concrete slab has good fire resistance, and the construction of the cast-in-place concrete slab is convenient and can be poured on-site according to needs to adapt to different building shapes and sizes.

[0037] In some embodiments, a connecting member 110 is provided between adjacent retaining piles 100. The connecting member 110 limits and supports the waterproof board 600, and the connecting member 110 fixes the retaining pile 100 and the waterproof board 600 together, improving the overall stability of the slope retaining structure. It can be understood that the connecting member 110 can use nails or screws, that is, directly fix the waterproof board on the retaining pile 100 through nails or screws; the connecting member 110 can also be an adhesive, that is, apply a special adhesive on the retaining pile 100 to fix the waterproof board 600; the connecting member 110 can also be a fixing clamp, that is, use a specially designed clamp to fix the waterproof board 600 on the retaining pile 100; of course, the connecting member 110 can also be formed by welding or hot melting, that is, for certain types of waterproof boards, welding or hot melting can be used for fixing; the connecting member 110 can also be ropes or steel wires: tie the waterproof board to the retaining pile using ropes or steel wires.

[0038] In some embodiments, the connecting member 110 includes steel bars. The steel bars tie the waterproof board 600, and the ends of the steel bars are embedded in the retaining pile 100. The extruded polystyrene board is fixed between the drain pipe 200 and the baffle 500 by implanting steel bars on the retaining pile 100. This method of using steel bars for connection can improve the connection strength, that is, enhance the connection firmness between the retaining pile 100 and the waterproof board 600, and the steel bar tying will not damage the waterproof board 600, without perforating the waterproof board 600, effectively ensuring the waterproof performance of the waterproof board 600. Moreover, using steel bars for connection can enhance the overall stability of the retaining structure. The steel bars can also better share the external load and adapt to the deformation of the structure to a certain extent, improving the durability and service life of the slope retaining structure.

[0039] In some embodiments, the filler 400 includes sand and gravel. A cover 240 is provided at the top of the drain pipe 200, and a plurality of drain holes 210 are formed on the outer periphery of the drain pipe 200. The sand and gravel fill the gaps around the drain pipe 200. The sand and gravel filling can effectively fix the drain pipe 200. At the same time, the filler 400 is located outside the soil body between adjacent retaining piles 100, preventing the loss of the soil body between adjacent retaining piles 100.

[0040] For the slope retaining in the prior art, if an internal drainage device is set, once it is blocked, it is difficult to repair. In some embodiments of the present application, a filter layer 220 is provided on the outer periphery of the drain pipe 200. The filter layer 220 separates the filler 400 and the drain pipe 200. The filter layer can filter water, preventing impurities from entering the drain pipe 200 through the drain holes 210 and causing blockage of the drain pipe 200. Through these anti-blocking measures, the problem of drainage during the long-term use of the permanent slope retaining structure can be solved, ensuring the service life of the drain pipe 200.

[0041] In some embodiments, the filter layer 220 includes geotextile, which is tied to the outer periphery of the drain pipe 200 by tying ropes. The geotextile is non-woven geotextile. Specifically, two layers of non-woven geotextile are wrapped around the outside of the drain pipe 200. The non-woven geotextile can filter water and prevent impurities from entering the drain pipe 200 through the drain holes 210, thus preventing the blockage of the drain pipe 200, and can solve the problem of drainage during the long-term use of the permanent slope support structure.

[0042] Specifically, the geotextile is tied and fixed to the drain pipe 200 by iron wires. The drain pipe 200 wrapped with the non-woven geotextile is placed between the support piles 100, and double-layer non-woven geotextile and sand are used for filling, which plays a role in filtering water, prevents the drain pipe 200 from being blocked, and prevents the loss of slope soil, which is beneficial for long-term use. Using iron wires to tie the geotextile can ensure that the geotextile is firmly fixed on the drain pipe 200, making the geotextile not easy to loosen or slip. Moreover, the operation using iron wires is relatively simple, easy to implement, and the material cost is low. Iron wires are easy to be applied to drain pipes 200 of various sizes and shapes, and if necessary, using iron wires can facilitate the replacement or adjustment of the geotextile.

[0043] In some embodiments, a plurality of drain pipes 300 are provided along the height direction. The drain pipe 200 includes a plurality of pipe sections 230. The adjacent pipe sections 230 and the drain pipes 300 are connected and communicated through tee joints 240. The tee joints 240 facilitate the installation of the drain pipe 200 and the drain pipes 300, simplify the process of pipeline connection, and can reduce the complexity of pipeline layout and save space. The tee joints 240 have high flexibility and can adjust the connection direction according to actual needs, so that the drain pipes 300 can smoothly discharge the water in the drain pipe 200 to the outside of the slope. Using the tee joints 240 to realize the connection and communication between the drain pipes 300 and the drain pipe 200 can improve the drainage efficiency, is beneficial for smooth drainage, and the tee joints 240 can also enhance the sealing performance and reduce the risk of leakage. Using the tee joints is convenient for subsequent maintenance and is easier to operate during future maintenance (replacement of the drain pipes 300).

[0044] Both the drain pipes 300 and the drain pipe 200 are made of PVC pipes. The drain pipes 300, the drain pipe 200 and the tee joints 240 are made of PVC pipes. Specifically, the tee joint 240 includes a first end at the top, a second end at the bottom, and a third end perpendicular to the first end and the second end. The first end of the tee joint 240 is connected and communicated with the bottom end of the top pipe section 230, the second end of the tee joint 240 is connected and communicated with the top end of the bottom pipe section, and the third end of the tee joint 240 is connected and communicated with the drain pipe 300, that is, the drain pipe 300 is vertically arranged with the drain pipe 200, and the drain pipe 300 discharges the water in the drain pipe 200 to the outside of the slope.
