Excavation construction method of soft soil layer deep foundation pit
The invention relates to an excavation construction method of a soft soil layer deep foundation pit, and belongs to the field of deep foundation pit construction.The method comprises the following steps that S1, holes are drilled in preset positions, first-stage secant piles are poured, and a first-stage enclosure wall is defined by the first-stage secant piles; S2, a first-stage foundation pit isexcavated in the first-stage enclosure wall; S3, holes are drilled in preset positions of the bottom of the first-stage foundation pit, second-stage secant piles are poured, and a second-stage enclosure wall is defined by the second-stage secant piles; S4, a bearing table is poured between the first-stage secant piles and the second-stage secant piles, so that an integral enclosure structure is formed among the first-stage secant piles, the bearing table and the second-stage secant piles; and S5, a second-stage foundation pit is excavated in the second-stage enclosure wall. The construction method has the effect of improving the construction efficiency.
本申请涉及一种软土层深基坑挖土施工方法，属于深基坑施工领域，包括以下步骤：步骤S1：在预定位置钻孔浇筑一级咬合桩，使一级咬合桩围成一级围墙；步骤S2：在一级围墙内开挖一级基坑；步骤S3：在一级基坑底部的预定位置钻孔浇筑二级咬合桩，使二级咬合桩围成二级围墙；步骤S4：在一级咬合桩和二级咬合桩之间浇筑承载台，使一级咬合桩、承载台和二级咬合桩之间形成整体的围护结构；步骤S5：在二级围墙内开挖二级基坑。本申请具有提高施工效率的效果。
