Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit support, in particular to an assembled steel sheet pile. Background Art

[0002] Steel sheet piles are a commonly used foundation pit support structure. Compared with traditional support methods such as cast-in-place piles, steel sheet piles are usually constructed through piling equipment, and have the characteristics of fast construction speed and high degree of mechanization. However, the cross-sectional thickness of traditional U-shaped steel piles is relatively thin, and the joints between steel sheet piles are relatively large, which is not conducive to water stopping, and it is impossible to remove groundwater outside the steel sheet piles. The corner interface is relatively weak, and the cohesive force of the soil outside the steel sheet piles is not fully utilized. At the same time, when laying out the perimeter purlins, they are usually connected to the steel sheet piles by welding, which is difficult to dismantle and not conducive to recycling. The contact surface between the steel sheet piles and the perimeter purlins is insufficient, and the supporting function cannot be fully exerted.
