[0023] Referring to Figure 1 , Figure 2 and Figure 4 , the present application proposes a retaining wall structure suitable for geological disaster control, which comprises: a pile cap 5 connected with a pile 15; a bottom cushion layer 14 connected with the pile cap 5; a retaining wall 1 connected with the bottom cushion layer 14; a buttress 4 partially connected with the retaining wall 1 and partially connected with the bottom cushion layer 14; a cap 3 arranged at the top end of the retaining wall 1, and the cap 3 is connected with the retaining wall 1.

[0024] The base of the retaining wall structure for geological disaster control is formed by the pile 15 and the bearing platform 5, and other components of the retaining wall structure for geological disaster control are installed on the ground through the pile 15 and the bearing platform 5. The pile 15 can be a cast-in-place pile or a prefabricated pile, the pile 15 is inserted into the ground, the bearing platform 5 is poured on the top of the pile 15, the bottom cushion layer 14 is poured on the bearing platform 5, the retaining wall 1 is connected to the bottom cushion layer 14, one side of the retaining wall 1 is a retaining wall surface, and the other side of the retaining wall 1 is provided with a plurality of buttresses 4 at intervals, the buttresses 4 are in a triangular shape, one straight angle side of the buttresses 4 is connected to the bottom cushion layer 14, and the other straight angle side of the buttresses 4 is connected to the retaining wall 1. The cap 3 is arranged at the top end of the retaining wall 1 to prevent soil erosion, maintain soil stability, and prevent soil sliding or collapse.

[0025] Specifically, the retaining wall 1 structure is arranged on a natural or man-made high slope, the retaining wall surface of the retaining wall 1 faces the slope, the retaining wall 1 resists the slope to avoid geological disasters such as mountain collapse, landslide, and debris flow, and the retaining wall 1 is connected to the ground stably through the bearing platform 5 and the pile 15 structure. The retaining wall 1 can bear the huge vertical load and lateral force of the wall body. The pile 15 is inserted into the ground and connected to the bearing platform 5, and the gravity of the retaining wall 1 can be effectively distributed to the deep underground through the above-mentioned base form to prevent soil sliding or foundation settlement. The cap 3 can effectively prevent soil erosion of the retaining wall 1, maintain soil stability of the high slope, prevent soil sliding or collapse, and improve the stability of the high slope to better avoid the occurrence of geological disasters.

[0026] In addition, the pile 15 can be a cast-in-place pile or a prefabricated pile, and the use of the cast-in-place pile or the prefabricated pile ensures the bearing capacity and stability of the pile foundation. The bearing platform 5 is poured at the top end of the pile foundation to form a stable foundation connection with the pile 15, which can effectively transfer the lateral pressure and top gravity from the retaining wall 1, especially in the case of landslide or soil loosening, to ensure that the retaining wall structure does not displace or overturn.

[0027] Secondly, the bottom cushion layer 14 is connected to the retaining wall 1 through the bearing platform 5, one side of the retaining wall 1 bears the lateral pressure from the high slope, and the bottom cushion layer 14 provides additional stability. Through the connection of the concrete structure, the structural stability of the retaining wall under the stress state can be ensured, and the deformation can be reduced. Through the above-mentioned connection, the compressive strength of the whole structure is enhanced, and the retaining wall 1 can effectively bear the lateral soil pressure from the high slope. At the same time, the existence of the bottom cushion layer 14 can effectively disperse the soil pressure and provide a larger contact area, thereby avoiding the structural damage caused by local stress concentration.

[0028] The foundation 5, piles 15, bottom cushion layer 14, retaining wall 1, and buttress 4 are all concrete structures. Furthermore, by placing the cap 3 on top of the retaining wall 1, directly covering the top of the retaining wall, rainwater and external soil erosion are prevented, maintaining soil stability. The cap 3 is made of thick, large stones, which can be a single large block or composed of multiple stones joined together. The cap 3 can resist wind and rain erosion and soil pressure. The presence of the cap 3 enhances the stability of the entire retaining wall 1 structure, helps prevent damage to the retaining wall 1, and increases the overall stability of the retaining wall through its own weight. When the soil is under pressure, the cap 3 effectively disperses the pressure, preventing soil slippage or collapse, allowing the retaining wall to remain stable under extreme climatic conditions.

[0029] As a supporting structure, the buttress 4, with its triangular shape, effectively transforms the lateral pressure of the retaining wall 1 into a more uniform distribution. The connection between the right-angled sides of the buttress and the bottom cushion layer 14 and the retaining wall 1 enables it to act as a beam support under pressure, preventing the retaining wall from tilting or deforming due to excessive lateral soil pressure.

[0030] Understandably, the above design significantly improves the load-bearing capacity of the retaining wall. Especially when encountering severe geological disasters such as landslides and debris flows, the buttress can effectively reduce the lateral displacement of the retaining wall and prevent the wall from becoming unstable.

[0031] See Figure 1 and Figure 2 As shown, in some embodiments, the cap 3 is further included with: a stepped hole 7, which is disposed on the cap 3, and includes a large hole and a small hole, and is a through hole; an embedded part 8, which is embedded in the retaining wall 1 and partially extends into the stepped hole 7, the embedded part 8 including a straight section and a hook section, the hook section being completely inserted into the retaining wall 1, the straight section partially extending out of the retaining wall 1, and being able to completely pass through the small hole of the stepped hole 7 and partially extend into the large hole; and a nut 10, which is screwed onto the embedded part 8 and is located in the stepped hole 7. The nut 10 is screwed onto the embedded part 8, and the outer diameter of the nut 10 is larger than the inner diameter of the small hole. The cap 3 is installed onto the retaining wall 1 using the above structure.

[0032] In this embodiment, the cap 3 can be cut to create a stop surface. This stop surface abuts against the retaining surface of the retaining wall 1, preventing horizontal displacement of the cap 3 through the contact between the stop surface and the retaining wall 1. This further improves the stability of the cap 3.

[0033] See Figure 1 and Figure 2As shown, in some embodiments, it further includes a gasket 9, which is located within the stepped hole 7. A stepped surface is formed within the stepped hole 7, and the gasket 9 is disposed between the nut 10 and the stepped surface. By providing the gasket 9, damage to the nut 10 can be effectively prevented, and loosening of the nut 10 can be avoided.

[0034] See Figure 1 and Figure 2 As shown, in some embodiments, the stepped hole 7 is filled with epoxy resin 11. The filling with epoxy resin 11 can first ensure the sealing of the stepped hole 7, improve the corrosion resistance of the embedded part 8 and the nut 10 structure, and the filling with epoxy resin 11 can further improve the stability of the connection between the cap 3 and the retaining wall 1.

[0035] See Figure 1 and Figure 3 As shown, in some embodiments, the structure further includes: a first reinforcing steel skeleton structure 2, which is disposed within the retaining wall 1; a second reinforcing steel skeleton structure 12, which is disposed within the buttress 4; and a third reinforcing steel skeleton structure 16, which is disposed within the base layer 14. The first reinforcing steel skeleton structure 2, the second reinforcing steel skeleton structure 12, and the third reinforcing steel skeleton structure 16 are all composed of main bars and stirrups. These structures are used to restrain the concrete structure and improve the integrity of the concrete components such as the retaining wall 1, the buttress 4, and the base layer 14.

[0036] Therefore, this embodiment, through the structural design of the first reinforcing steel cage structure 2, the second reinforcing steel cage structure 12, and the third reinforcing steel cage structure 16, not only enhances the crack resistance and integrity of the concrete structure, but also effectively restrains the development of cracks in the concrete structure under stress. In practical applications, especially under tension, compression, and deformation, it can distribute stress more evenly to all parts. Thus, the above structural design improves the tensile and compressive strength of retaining walls, buttresses, and foundation layers. By rationally arranging the reinforcing steel, the toughness of concrete components under external forces such as lateral soil pressure and frost heave can be enhanced, preventing cracking or instability.

[0037] See Figure 1 and Figure 4 As shown, in some embodiments, the structure further includes: permeable holes 13, which are disposed on the retaining wall 1; and backfill soil layer 6, which partially contacts the bottom cushion layer 14. The weight of the backfill soil layer 6 can effectively resist the overturning and sliding of the retaining wall 1 structure. Preferably, backfill soil layer 6 is provided on both sides of the bottom cushion layer 14 located on the retaining wall 1. The permeable holes 13 are used for drainage, to drain the soil moisture behind the retaining wall 1, to prevent surface water infiltration, to prevent water accumulation behind the retaining wall 1 from forming hydrostatic pressure, and to reduce the frost heave pressure and expansion pressure of the soil.

[0038] Thus, the water permeable holes 13 can effectively avoid the accumulation of water behind the retaining wall. The accumulated water in the soil may cause hydrostatic pressure or water erosion to the retaining wall, especially during heavy rainfall. The concentration of water pressure may cause displacement or damage to the retaining wall. The water permeable holes provide a drainage channel to drain excess water, thereby avoiding structural damage caused by excessive water pressure.

[0039] It can be understood that, through the optimization of the drainage system, the retaining wall can maintain a lower water and soil pressure, reducing the adverse effects caused by the water and soil pressure. At the same time, the design of the backfill layer enhances the anti-sliding ability of the retaining wall by using the weight of the soil, improving the overall stability of the retaining wall.

[0040] In summary, the various parts of the retaining wall structure suitable for geological disaster control are mechanically matched between the pile cap 5, the pile 15, the reinforced framework, the buttress 4 and the cap 3. Each structural unit complements each other in the overall design, effectively improving the stability and disaster resistance of the overall structure. The structure can provide effective protection in various geological disasters such as mountain collapse, landslide, debris flow, etc. The retaining wall not only can withstand external pressure for a long time, but also can ensure the stability of the high slope under extreme climate and geological environment, greatly reducing the risk of geological disasters. It ensures that the retaining wall can maintain its stability and function when facing strong geological disasters and extreme environments, achieving the purpose of effectively preventing and controlling geological disasters.

Any equivalent structural transformation using the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the scope of protection of the present application.
