Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering, and in particular to a slope protection retaining wall for water conservancy projects. Background Technology

[0002] In existing technologies, water conservancy engineering is a branch of civil engineering, focusing on the development, utilization, regulation, and protection of water resources. It includes the design and construction of facilities such as reservoirs, dams, canals, and slope protection. Slope protection refers to protective measures taken to prevent landslides, collapses, and other disasters caused by natural or human factors (such as water erosion and soil erosion). Slope protection takes various forms, including vegetated slope protection, gabion slope protection, and concrete slope protection. Retaining walls are structures used to support soil or water bodies, typically to prevent soil sliding or water erosion. Depending on the materials and uses, retaining walls can be classified as gravity retaining walls, cantilever retaining walls, and reinforced soil retaining walls.

[0003] Slope protection retaining walls for hydraulic engineering are structures that combine slope protection and retaining walls, specifically designed for use in hydraulic engineering projects. They aim to protect slope stability, prevent soil erosion, and perform functions such as flood control and scour resistance. For fixing the infill, a combination of steel mesh and anchor cables is often used. However, the construction process for anchor cables is relatively complex and prone to failure. Utility Model Content

[0004] The main purpose of this utility model is to provide a retaining wall for slope protection in water conservancy projects, which aims to solve the problem of combining the reinforcing steel mesh and anchor cables in the retaining wall filling and fixing. The construction process of anchor cables is relatively complicated and prone to fixing failure.

[0005] To achieve the above objectives, this utility model provides a retaining wall for slope protection in water conservancy projects, corresponding to a soil foundation setting, including: A fixed base is provided on the upper surface of the soil foundation; A fixing rod passes through the fixing base and fixes the fixing base to the soil foundation; A filler layer is fitted onto the side of the subgrade foundation, the outer surface of the filler layer forming an angle of 75 to 85 degrees with the top of the subgrade foundation, wherein the filler layer comprises clay and / or crushed stone; Reinforcing mesh, integrated into the exterior of the filler layer; Multiple anchor cable assemblies are distributed on the steel mesh. Each anchor cable assembly includes an anchor cable and a compression member. The compression member is connected to the middle of the steel mesh in the height direction. One end of the anchor cable is connected to the compression member, and the other end is connected obliquely upward to the fixed base. The outer cement surface is attached to the outside of the steel mesh, and the outer surface of the outer cement surface forms an angle of 110 to 130 degrees with the top of the soil foundation.

[0006] Furthermore, the soil foundation is pre-fixed with an inner fastener corresponding to the lower end of the fixing rod.

[0007] Furthermore, the fixed rod is at an angle of 30 to 60 degrees to the horizontal plane.

[0008] Furthermore, the anchor cable is at an angle of 30 to 60 degrees to the horizontal plane.

[0009] Furthermore, the anchor cable is set at an angle of 80 to 90 degrees to the fixing rod.

[0010] Furthermore, the plurality of said anchor cable assemblies are divided into at least two groups in height at one end of the steel mesh.

[0011] Furthermore, the compression member is fastened to the steel mesh, and the anchor cable and the compression member are connected by a thread.

[0012] Furthermore, steel wire mesh is tied between each mesh opening of the steel mesh.

[0013] Furthermore, a protective pipe is provided on the soil foundation corresponding to the outer periphery of the anchor cable.

[0014] Furthermore, cement is filled between the outer walls of both ends of the protective pipe along its length and the soil foundation.

[0015] This utility model provides a retaining wall for slope protection in hydraulic engineering. A fixing pin passes through a fixing base to secure the base to the soil foundation. A reinforcing mesh is integrated into the outer surface of the infill layer. Multiple anchor cable assemblies are distributed on the reinforcing mesh. The anchor cables pass obliquely upwards through the soil foundation and connect to the fixing base. Because the outer surface of the infill layer is at an angle of 75 to 85 degrees, and the anchor cables are obliquely upwards, the infill layer is compressed and supported by the reinforcing mesh, thus optimizing the fixing effect of the infill layer and reducing the possibility of abnormal slippage of the reinforcing mesh. An outer cement surface is integrated with the reinforcing mesh. The outer cement surface protects the infill layer and the reinforcing mesh, while the reinforcing mesh also serves as a skeleton for the outer cement surface, providing structural strength. Notably, the fixing pin and anchor cables can be adjusted at the location of the fixing base. Attached Figure Description

[0020] Reference Figures 1 to 4 In one embodiment of this utility model, a retaining wall for slope protection in water conservancy projects, corresponding to the soil foundation 010, includes: A fixed base 100 is disposed on the upper surface of the soil foundation 010; A fixing rod 200 passes through the fixing base 100 to fix the fixing base 100 to the soil foundation 010; A filler layer 300 is fitted to the side of the soil foundation 010. The outer surface of the filler layer 300 forms an angle of 75 to 85 degrees with the top of the soil foundation 010. The filler layer 300 includes clay and / or crushed stone. The reinforcing mesh 400 is attached to the outer surface of the filling layer 300; Multiple anchor cable assemblies are distributed on the steel mesh 400. Each anchor cable assembly includes an anchor cable 510 and a pressing member 520. The pressing member 520 is connected to the middle part of the steel mesh 400 in the height direction. One end of the anchor cable 510 is connected to the pressing member 520 and the other end is obliquely upward and connected to the fixed base 100. The outer cement surface 600 is attached to the outside of the steel mesh 400, and the outer surface of the outer cement surface 600 forms an angle of 110 to 130 degrees with the top of the soil foundation 010.

[0021] In existing technologies, the fixation of the filling is often achieved by combining steel mesh and anchor cables. However, the construction process of anchor cables is relatively complex and prone to fixation failure.

[0022] The retaining wall for water conservancy projects provided by this utility model is set up corresponding to the soil foundation 010. The fixing base 100 is set on the upper surface of the soil foundation 010. The shape of the fixing base 100 can be various, and the material of the fixing base 100 is preferably a high-strength alloy.

[0023] The fixing pin 200 passes through the fixing base 100 and fixes the fixing base 100 to the soil foundation 010. The fixing method between the fixing pin 200 and the soil foundation 010 can be friction or by pre-embedding a fixing structure in the soil foundation 010 and combining it with the fixing pin 200.

[0024] The infill layer 300 is fitted onto the side of the subgrade foundation 010. The outer face of the infill layer 300 forms an angle of 75 to 85 degrees with the top of the subgrade foundation 010. The angle of the infill layer 300 serves to provide a foundation for subsequent reinforcement mesh 400 fixation optimization. The infill layer 300 comprises clay and / or crushed stone. In other embodiments, the infill layer 300 may also include other materials to provide structural strength and waterproofing.

[0025] The reinforcing mesh 400 is integrated into the exterior facade of the infill layer 300. The structure of the reinforcing mesh 400 is designed with reference to existing technologies. For example, the reinforcing mesh 400 includes transverse and longitudinal reinforcing bars, which are connected by welding or binding.

[0026] Multiple anchor cable assemblies are distributed on the reinforcing mesh 400. The specific location and number of anchor cable assemblies are selected and designed according to needs. Anchor cable assemblies include anchor cables 510 and pressure members 520. Pressure members 520 are connected to the middle of the reinforcing mesh 400 in the height direction. The fixing method of pressure members 520 on the reinforcing mesh 400 can be varied, such as welding or fastening. One end of the anchor cable 510 is connected to the pressure member 520, while the other end is obliquely upward and connected to the fixed base 100. Specifically, the anchor cable 510 obliquely passes through the soil foundation 010 and connects to the fixed base 100. The connection method between the anchor cable 510 and the fixed base 100 can be threaded connection, bolted connection, or welding. Because the outer facade of the infill layer 300 has an angle of 75 to 85 degrees, and the anchor cables 510 are obliquely upward, the infill layer 300 is pressed and lifted obliquely upward by the reinforcing mesh 400, thereby optimizing the fixing effect of the infill layer 300 and reducing the possibility of abnormal slippage of the reinforcing mesh 400.

[0027] The outer cement surface 600 is bonded to the outer steel mesh 400. The outer cement surface 600 protects the infill layer 300 and the steel mesh 400, while the steel mesh 400 also serves as the skeleton of the outer cement surface 600, providing structural strength. The outer facade of the outer cement surface 600 forms an angle of 110 to 130 degrees with the top of the subgrade foundation 010, ensuring effective support.

[0028] In summary, the fixing pin 200 passes through the fixing base 100, fixing the fixing base 100 to the soil foundation 010. The reinforcing mesh 400 is integrated with the outer surface of the infill layer 300, and multiple anchor cable assemblies are distributed on the reinforcing mesh 400. The anchor cable 510 passes obliquely upward through the soil foundation 010 and connects to the fixing base 100. Since the outer surface of the infill layer 300 has an angle of 75 to 85 degrees, and the anchor cable 510 is obliquely upward, the infill layer 300 is compressed and lifted obliquely upward by the reinforcing mesh 400, thereby optimizing the fixing effect of the infill layer 300 and reducing the possibility of abnormal slippage of the reinforcing mesh 400. The outer cement surface 600 is integrated with the outside of the reinforcing mesh 400. The outer cement surface 600 protects the infill layer 300 and the reinforcing mesh 400, and the reinforcing mesh 400 also serves as the skeleton of the outer cement surface 600, providing structural strength. In particular, the fixing pin 200 and the anchor cable can be adjusted at the location of the fixing base.

[0029] In one embodiment, the soil foundation 010 is pre-fixed with an inner fastener corresponding to the lower end of the fixing rod 200.

[0030] In this embodiment, the fixing effect of the fixing rod 200 is improved by setting an internal fastener within the soil foundation 010. The internal fastener can take various forms; for example, a hole can be drilled in the upper surface of the soil foundation 010, and the internal fastener can be pre-embedded using cement or other methods. During use, the fixing rod 200 penetrates the soil foundation 010 and connects with the internal fastener, thus improving the fixing effect of the fixing rod 200. The connection method between the internal fastener and the fixing rod 200 can be the insertion of the external thread of the fixing rod 200, etc.

[0031] In one embodiment, the fixing rod 200 is at an angle of 30 to 60 degrees to the horizontal plane.

[0032] In this embodiment, the angle of the fixing rod 200 is limited, so that the fixing rod 200 can have a better fixing effect while better fixing the anchor cable 510.

[0033] In one embodiment, the anchor cable 510 is at an angle of 30 to 60 degrees to the horizontal plane.

[0034] In this embodiment, the angle of the anchor cable 510 is limited so that the anchor cable 510 can better fix the steel mesh 400.

[0035] In one embodiment, the anchor cable 510 is positioned at an 80 to 90 degree angle to the fixing rod 200.

[0036] In this embodiment, the angle between the anchor cable 510 and the fixing pin 200 is limited so that the anchor cable 510 will not cause the fixing pin 200 to loosen, while the anchor cable 510 and the fixing pin 200 can also jointly fix the soil foundation 010, reducing the risk of soil foundation 010 being lost.

[0037] Reference Figures 1 to 2 In one embodiment, the plurality of said anchor cable assemblies are divided into at least two groups in height at one end of the steel mesh 400.

[0038] In this embodiment, the lower end of the anchor cable assembly is not connected to the reinforcing mesh 400 at a uniform height. For example, the pressing member 520 of the anchor cable assembly is set at two positions on the reinforcing mesh 400, so that the anchor cable assembly can be fixed at multiple positions at the height of the reinforcing mesh 400.

[0039] In one embodiment, the compression member 520 is fastened to the steel mesh 400, and the anchor cable 510 is threadedly connected to the compression member 520.

[0040] In this embodiment, a structural method for the compression member 520 is provided. For example, the compression member 520 is claw-shaped, so that it can be fastened to the steel mesh 400. The anchor cable 510 and the compression member 520 are connected by threads, which can also facilitate installation and fixation.

[0041] In one embodiment, steel wire mesh is tied between each mesh opening of the steel mesh 400.

[0042] In this embodiment, by setting wire mesh between each mesh opening of the steel mesh 400, the steel mesh 400 as a whole can have a better fixing effect and reduce the loss of the soil foundation 010.

[0043] Reference Figures 1 to 2 In one embodiment, a protective pipe 700 is provided on the soil foundation 010 corresponding to the outer periphery of the anchor cable 510.

[0044] In this embodiment, the protective pipe 700 is pre-installed in the soil foundation 010 to provide a foundation for the subsequent installation of the anchor cable 510, and at the same time, it can also protect the anchor cable 510.

[0045] In one embodiment, cement is used to fill the space between the outer walls of both ends of the protective pipe 700 along its length and the soil foundation 010.

[0046] In this embodiment, cement is introduced at both ends of the protective pipe 700 along its length to provide a foundation for fixing the protective pipe 700, especially for fixing the soil foundation 010 at the lower end of the protective pipe 700.

[0047] In summary, the retaining wall for hydraulic engineering provided by this utility model has a fixing rod 200 that passes through a fixing base 100 to fix the fixing base 100 to the soil foundation 010. A reinforcing mesh 400 is integrated into the outer surface of the filling layer 300. Multiple anchor cable assemblies are distributed on the reinforcing mesh 400. Anchor cables 510 pass obliquely upward through the soil foundation 010 and connect to the fixing base 100. Because the outer surface of the filling layer 300 has an angle of 75 to 85 degrees, and the anchor cables 510 are obliquely upward, the filling layer 300 is compressed and lifted obliquely upward by the reinforcing mesh 400, thereby optimizing the fixing effect of the filling layer 300 and reducing the possibility of abnormal slippage of the reinforcing mesh 400. An outer cement surface 600 is integrated into the outside of the reinforcing mesh 400. The outer cement surface 600 protects the filling layer 300 and the reinforcing mesh 400, while the reinforcing mesh 400 also serves as the skeleton of the outer cement surface 600, providing structural strength. In particular, the fixing rod 200 and anchor cable can be adjusted at the fixed base position.

[0048] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
