拉森钢板桩在富水砂层深基坑支护中的应用

Application of larsen steel sheet pile in deep foundation pit support in water rich sand layer

随着城市地下空间的开发利用,基坑支护技术形式、施工工艺也日益成熟,基本能满足不同规模、形状、开挖深度、地层结构、环境条件差异的基坑工程需求。拉森钢板桩自20世纪90年代用于基坑支护工程,便凭借其独特优势占据一方市场。本文以富水砂层深基坑为例,介绍拉森钢板桩在此类地层小型基坑工程中的适用性。

With the development and utilization of urban underground space,the form and construction technology of foundation pit support are becoming more and more mature,which can basically meet the needs of foundation pit engineering with different scale,shape,excavation depth,stratum structure and environmental conditions.Since Larsen steel sheet pile was used in foundation pit supporting engineering in 1990s,it has occupied one market with its unique advantages.This paper introduces the applicability of Larsen steel sheet pile in the small foundation pit engineering of this kind of stratum,taking the deep foundation pit of rich water sand stratum as an example.
