Description

Technical Field

[0001] The utility model relates to the field of civil engineering facilities, in particular to a protective retaining wall which is lightweight, high in strength, good in protective effect and easy to construct. Background Art

[0002] In civil engineering, slope stability is one of the key factors to ensure engineering safety. Although traditional slope protection structures, such as gravity retaining walls and anchor supports, can meet the needs of slope stability to a certain extent, they often have problems such as bulky structure, high material consumption, and long construction period. Therefore, how to develop a light, efficient and easy-to-construct slope protection structure has become an urgent problem to be solved in the current field of civil engineering technology. Utility Model Content

[0003] The utility model provides a light retaining wall design with a plurality of holes opened in a main body, so as to solve the technical problems mentioned in the background technology.

[0004] In order to solve the above technical problems, the technical solution proposed by the utility model is:

[0005] A protective retaining wall comprises a retaining wall body and an anchoring assembly for anchoring the retaining wall body. The retaining wall body is provided with a plurality of holes extending along the height direction of the retaining wall body. The plurality of holes are arranged in sequence along the length direction of the retaining wall.

[0006] The design idea of ​​the above technical solution is that the protective retaining wall of the utility model is anchored by anchoring components to achieve protection of structures such as slopes. The retaining wall body adopts a porous hollow design, and the holes are evenly arranged in the length direction, which can significantly reduce the dead weight and save materials. The hole structure produces mechanical properties similar to those of a bridge hole, which can effectively disperse the load of the retaining wall body, thereby greatly reducing the stress concentration phenomenon and significantly improving the bearing capacity of the structure. At the same time, the above design further enhances the overall stability. When subjected to external loads, the interaction between the holes helps to reduce the risk of deformation and cracking of the structure.

[0007] As a further preferred embodiment of the above technical solution, the plurality of holes are distributed non-equidistantly in the retaining wall body, and the spacing between the holes near the connection between the retaining wall body and the anchor assembly is greater than the spacing between the holes located in other parts of the retaining wall body. At the key stress points of the retaining wall body, such as the support points and the connection points, the spacing between the holes is appropriately increased to reduce stress concentration; while in the areas with less stress, the spacing between the holes is correspondingly reduced to achieve balanced utilization of materials.

[0008] As a further preferred embodiment of the above technical solution, the cross-sectional size of the hole located near the connection between the retaining wall body and the anchor assembly is smaller than the cross-sectional size of the hole located at other parts of the retaining wall body. The cross-sectional size of the hole in the key stress-bearing area is relatively small to reduce the weakening of the structural strength; while in the area with less stress, the cross-sectional size of the hole is appropriately increased to achieve efficient use of materials.

[0009] By precisely calculating and designing the shape and size of the holes, and drawing on and optimizing the mechanical properties of bridge holes, not only can the overall stability and mechanical properties of the structure be further improved, but the use of materials can also be minimized, thus achieving a perfect balance between economy and environmental protection.

[0010] As a further preferred embodiment of the above technical solution, the anchor assembly includes an anchor rod and an anchor, one end of the anchor rod penetrates the retaining wall body and is fixed to the surface of one side of the retaining wall body by the anchor. The anchor rod of the utility model is used as the main force-bearing component, and a stable tension transmission system is formed through the fixation of the anchor, which provides effective protection for the stability and bearing capacity of the retaining wall structure.

[0011] As a further preferred embodiment of the above technical solution, there is a clamping groove matching the shape of the anchor rod, and a wear-resistant layer is arranged inside the clamping groove. The anchor is specially designed to ensure that the anchor rod will not slip when subjected to tension, thereby ensuring the stability and reliability of tension transmission. The wear-resistant layer reduces wear caused by friction, extends the service life of the anchor, and ensures long-term stable clamping performance.

[0012] As a further preferred embodiment of the above technical solution, a pad is provided between the anchor and the retaining wall body. As a key transition component between the anchor and the retaining wall body, the pad plays an important role in the structure: it provides a larger bearing area, effectively disperses stress, and thus greatly enhances the overall strength and durability of the structure.

[0013] As a further preferred embodiment of the above technical solution, the anchor assembly further comprises an anchor pier, and the anchor pier (3) is arranged between the anchor and the pad. The anchor pier has sufficient bearing capacity and stability, and its shape and size are also accurately calculated and designed to form a coordinated and unified overall structure with the retaining wall and anchor rods and other components, which is used to provide additional support and further enhance the stability and safety of the structure; the connection relationship between the anchor pier and the anchor is tightly fitted, and it is fixedly connected to the anchor by high-strength bolts or welding, ensuring the stability of the anchor system and the effectiveness of transmitting tension.

[0014] As a further preferred embodiment of the above technical solution, the anchor pier is in a cylindrical or cubic shape, which is conducive to evenly distributing the tension and reducing stress concentration.

[0015] As a further preferred embodiment of the above technical solution, the diameter or side length of the anchor pier is 200-500 mm, and the height is 100-300 mm. The specific size is designed according to the diameter of the anchor rod, the size of the anchor and the required tensile force to ensure that the anchor pier has sufficient bearing capacity and stability.

[0016] The utility model has the following beneficial effects:

[0017] The protective retaining wall of the utility model has the characteristics of light weight, low cost and high strength. While maintaining high performance, it successfully achieves the goals of material saving and environmental protection. It is both economical and environmentally friendly. It has broad application prospects and promotion value in the fields of geotechnical engineering, road traffic, etc., and provides a new choice for modern engineering construction that is both economical and efficient.

[0032] In this embodiment, the anchor 8 is designed as a clamping groove matching the anchor rod 5, and has a special clamping groove to ensure that the anchor rod will not slip during tension. The inner surface of the clamping groove of the anchor 8 is coated with a wear-resistant material, such as a cemented carbide or ceramic coating, to reduce wear caused by friction, extend the service life of the anchor 8, and ensure long-term stable clamping performance.

[0033] In this embodiment, a backing plate 4 is provided between the anchor 8 and the retaining wall body 1. The steel backing plate 4 is selected to increase the force bearing area and disperse the pressure of the anchor on the retaining wall.
