Technical Field

[0001] The utility model relates to the technical field of foundation pit support equipment, in particular to a multi-level slope reduction and steel sheet pile combined construction device for foundation pit support. Background Art

[0002] Foundation pit support is a key technology in civil engineering, especially in urban high-rise buildings and subway projects. With the acceleration of urbanization, foundation pit projects are increasingly facing complex geological conditions, limited construction space and strict environmental protection requirements.

[0003] Currently, among the existing implementation schemes, a common foundation pit support method is to use steel sheet piles for support. As a traditional support method, steel sheet piles have the advantages of fast construction speed and reusability. However, the application of this method is limited in deep foundation pits or complex geological conditions because it may not provide sufficient lateral support, especially in areas with unstable soil or high groundwater levels.

[0004] Another method is to use multi-level slope reduction combined with soil nail walls or anchor rods. This method improves the stability of the slope by reducing the slope height in stages and adding soil nail walls or anchor rods. Although this method improves the stability of the slope, it still has problems with construction efficiency and adaptability, especially adaptability under different geological conditions and safety during construction.

[0005] In summary, although the existing foundation pit support implementation scheme has solved some technical problems to a certain extent, it still has the problems of being unable to be quickly disassembled and assembled, unable to be adjusted according to the slope angle, occupying a large space and being inconvenient to transport, resulting in low utilization rate.
