Description

Technical Field

[0001] The utility model belongs to the technical field of slope protection devices, and in particular relates to a slope anti-scouring device used for earth dam cofferdam construction. Background Art

[0002] A cofferdam refers to a temporary retaining structure built in the construction of permanent water conservancy facilities during water conservancy project construction. Its function is to prevent water and soil from entering the construction site of the building. During the construction of the cofferdam, slopes will be generated, and when the slopes are eroded, serious water and soil erosion will occur, thus affecting the safety of the cofferdam. After searching, it was found that the application number "202322208522.8" disclosed "a slope protection structure", which recorded "including: a main frame;

[0007] a fixed part is installed on the main frame. Among them, an auxiliary seat is welded to the top of the main frame, and the auxiliary seat is a U-shaped structure. The auxiliary seat is a water retaining member. When it rains, the rainwater on the slope will be collected and then flow downward, which will impact the soil on the slope. The erosion of the rainwater will cause the soil on the slope to be lost. When setting After the auxiliary seat is installed, rainwater can be blocked and drained, and the scouring of soil in the inner area of ​​the main frame by rainwater can be reduced. The above-mentioned protective structure can fix the main frame through the ground nails when in use, and multiple main frames can be assembled with the cooperation of the connecting rod and the connecting groove, so as to better protect the slope. However, there are still some shortcomings in the use of the above-mentioned device: since the structure of the main frame is fixed, it is inconvenient to install and assemble adjacent main frames, and the above-mentioned protective structure does not have a water-conducting effect. Therefore, when there is more rain on the top of the slope, the scouring force of the slope by rainwater is greater, and the protective rods arranged in the main frame will affect the growth of plants in the main frame, reducing the effect of preventing soil erosion on the slope. Based on this, we propose a device with simple structure, easy installation and better slope protection effect. Utility Model Content
