摘要
地下室施工时,如分批打入钢管围护桩同时按一定顺序挖土,待地下室壁板能足够抵抗土压力时,可及时填土同时拔出钢管桩并沉桩至其他所需位置,依次完成地下室施工,则围护钢管桩可重复使用,从而降低地下室的围护费用。借鉴SMW工法,设想钢管围护桩与水泥土结合支护结构,通过论述和探讨其结构性能和施工方法,则进一步扩展了可回收钢管围护桩的应用范围。
According to the sequence to dig up the mud and driven in turn steel pipe surrounding piles that constructed in the basement,enter the steel pipe surrounding piles until the basement wall can be enough to resist earth pressure,it can fill the soil at the same time pull out the steel pipe pile and pile to another desired location,followed by the completion of the basement construction,then the envelope of steel pipe pile can be reused,thereby reducing supporting cost of the basement.In order to further expand the application of steel pipe surrounding pile,learn from SMW engineering methods,envisage a supporting structure of a steel pipe with cement mixing soil,and discuss its mechanical properties and construction methods.
