钢板桩在受限空间基坑支护施工中的应用

Application of Steel Sheet Pile in Support Construction of Foundation Pit inConfined Space

为减少泵站基坑在限制空间开挖施工时对周围建筑物影响,解决基坑放坡土方挖运量大的难题,湖北省宜城市耕地防护及排涝工程采用打设钢板桩作为基坑的支护形式,其具有钢板桩可循环使用、开挖施工速度快、经济效益明显、对周边建筑物影响小的优势。可对后期同类工程施工有一定的指导借鉴作用。

In order to reduce the impact of construction on surrounding buildings during excavation and construction of foundation pit in confined space of pump station and solve the difficult problem of large excavation and transportation of earthwork for foundation pit sloping,steel sheet piles are used as the support form for foundation pit protection and drainage works inYicheng.It has the advantages of recyclable steel sheet piles,fast excavation and construction speed,obvious economic benefits and small impact on surrounding buildings.It can provide certain guidance and reference for similar project construction in later stage.
