Nowadays, with the development of economy and people’s demand for transportation, Each city is building the subway one after another, Larsen steel sheet pile must be an essential building material in the process of subway construction.
Larsen steel sheet pile has high strength, tight connection between pile and pile, good water separation effect, and can be reused. The common section types of steel sheet piles are mostly U-shaped or Z-shaped. U-shaped steel sheet piles are used in underground railway construction in China. Its sinking and removal methods, the use of machinery are the same as I-steel pile, but its construction method can be divided into single-layer steel sheet pile cofferdam, double-layer steel sheet pile cofferdam and screen. Due to the deep foundation pit during the construction of underground railway, in order to ensure its verticality and convenient construction, and make it can be closed and closed, screen structure is mostly used.
Larsen steel sheet pile length 12m, 15m, 18m, etc., channel steel sheet pile pile length of 6 ~ 9m, the model and length are determined by calculation. Steel sheet pile has good durability. After the foundation pit construction is completed, the steel sheet pile can be pulled out and recycled again. Convenient construction and short construction period; Channel steel sheet pile can not block water, in the area of high groundwater level, water isolation or precipitation measures should be taken. Channel steel sheet pile has weak bending ability, which is mostly used for foundation pit or trench with depth ≤4m, and a supporting or pulling anchor should be set at the top. The support stiffness is small and the deformation after excavation is large. Because of its strong bending ability, Larsen steel sheet pile is mostly used for deep 5m~8m foundation pit with low environmental requirements, depending on the support (pull anchor) installation.
