Sand-rich stratum mixing pile construction method
The invention provides a sand-rich stratum mixing pile construction method which comprises the following specific steps: determining a test range and a core pulling result of a steel sheet pile, setting a pile sinking positioning line according to the test range, chiseling off a concrete pavement in the test range, arranging a pile sinking guide frame according to the pile sinking positioning line, and carrying out core pulling on the pile sinking guide frame. The steel sheet pile is sunk along the pile sinking guide frame, after the steel sheet pile is sunk, the mixing pile is constructed, the strength of the mixing pile is tested, and after the age is reached, the steel sheet pile is pulled out, by means of the method, the mixing pile is constructed by fully combining geological and hydrological conditions and adopting a dynamic water isolation method, operability is high, dynamic construction is achieved, and construction efficiency is improved. The purposes of guaranteeing the pile forming quality of the stirring pile in the flowing water influence area, reducing the water leakage and sand leakage risk of foundation pit excavation, saving the construction cost and controlling the construction period can be well achieved.
本发明提供一种富砂地层搅拌桩施工方法，包括以下具体步骤，确定钢板桩的试验范围及抽芯结果，根据所述试验范围放设沉桩定位线，对所述试验范围内的混凝土路面进行凿除，根据所述沉桩定位线设沉桩导向架，沿着所述沉桩导向架沉设钢板桩，沉设所述钢板桩后，进行施工搅拌桩，测试所述搅拌桩的强度，到达龄期后，拔除所述钢板桩，通过使用此方法，充分结合地质水文条件，采用隔离动水方法施工搅拌桩，可操作性强，动态施工，能很好地实现保证动水影响区搅拌桩成桩质量，减少基坑开挖漏水漏砂风险，节省工程造价，控制工程工期的目的。
