Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, and particularly relates to a slope protection structure. Background Art

[0002] During the construction of water-related projects, especially water conservancy and hydropower projects and water transportation projects, cofferdams are often used to isolate the water-related area and the dry-operation working face. A cofferdam is a temporary water-retaining structure in the diversion project, used to enclose the construction foundation pit to ensure that the hydraulic structure can be constructed on dry land. After the diversion task is completed, if the cofferdam cannot be combined with the main project to become a part of the permanent project, it should be demolished. Cofferdams can be divided into earth-rock cofferdams, concrete cofferdams, steel sheet pile cofferdams, grass-earth cofferdams, bagged soil cofferdams, etc. according to the materials used. Among them, earth-rock cofferdams can make full use of local materials, have strong adaptability to the foundation, and simple construction technology, so they should be given priority. Since the earth-rock cofferdam has a fast construction speed and is used for water retaining immediately after construction, considering the settlement during the use stage of the cofferdam and the slope protection work, commonly used ones include reinforced gabions and stone revetments. However, the construction progress of the reinforced gabion revetment is slow, consumes a lot of materials, and has high costs; the stability and engineering appearance of the stone revetment are poor.

[0003] The existing spliced frame type slope protection component, slope protection device and retaining wall with the application number 201610513054.7 are composed of structural units with a square main view. The structural units are spliced at the four corners, and adjacent structural units can only be obliquely connected, making it difficult to be spliced side by side along the length direction of the slope, and difficult to form a layer structure arranged up and down. Not only can the upper and lower adjacent structural units not be staggered in the length direction of the slope, but also the upper and lower layers cannot be staggered in the thickness direction of the slope to form a stepped structure, resulting in poor overall strength and unsatisfactory slope protection stability. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a slope protection structure with simple structure, large overall strength and good slope protection stability.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A slope protection structure includes a plurality of slope protection units and a plurality of connectors. Each slope protection unit includes an outer wall panel and an embedded plate fixedly connected in a T shape. Each slope protection unit is arranged in multiple layers on the slope. The outer wall panels of each layer of slope protection units face outward and are sequentially spliced along the length direction of the slope and connected into a whole through connectors. The embedded plate faces inward and is embedded in the slope. The outer wall panel of the upper slope protection unit is supported on the embedded plate of the lower slope protection unit, and the upper slope protection unit and the lower slope protection unit are arranged in a staggered manner in the thickness direction of the slope to form a stepped structure.

[0007] As a further improvement of the above technical solution:

[0008] The upper slope protection units and the lower slope protection units are arranged staggeredly in the length direction of the slope.

[0009] The outer wall panels of the upper slope protection units are supported on the inner embedded plates of two adjacent corresponding lower slope protection units.

[0010] The symmetry plane of the upper slope protection unit is coplanar with the splicing plane of two adjacent corresponding lower slope protection units.

[0011] The space between the slope protection units and the slope is filled with soil and stones.

[0012] Connection holes are respectively arranged at both ends of the outer wall panel, and the connecting pieces are inserted into the connection holes of two adjacent outer wall panels.

[0013] The connecting pieces are steel wires or iron wires.

[0014] Lifting holes are arranged on the inner embedded plates.

[0015] The slope protection units are reinforced concrete units.

[0016] The slope protection units are 1.5 m in length, 1.5 m in width and 1 m in height.

[0017] Compared with the prior art, the advantages of the present utility model are as follows:

[0018] In the slope protection structure of the present utility model, the slope protection units are arranged in multiple layers on the slope. The outer wall panels of the slope protection units in each layer face outwards, are spliced in sequence along the length direction of the slope, and are connected into a whole through the connecting pieces. The inner embedded plates face inwards and are embedded in the slope. The outer wall panels of the upper slope protection units are supported on the inner embedded plates of the lower slope protection units, and the upper slope protection units and the lower slope protection units are arranged staggeredly in the thickness direction of the slope to form a stepped structure. Each layer of slope protection units is spliced side by side along the length direction of the slope to form a layer structure arranged up and down. The upper and lower layers are staggered in the thickness direction of the slope to form a stepped structure. The overall strength is large and the slope protection stability is good.

[0030] In this slope protection structure, each slope protection unit 1 is arranged in multiple layers on the slope.
