River deep foundation pit construction method
The invention provides a river-near deep foundation pit construction method which comprises the following steps: S1, leveling a site, carrying out lofting according to a construction drawing, and drawing lines on the site; s2, mixing piles and steel sheet piles are constructed on the outer side of the area of the foundation pit, and cast-in-place piles are constructed on the inner side of the area of the foundation pit; s3, a step slope is arranged on the outer side of the mixing pile, and the part, higher than the water area, of the step slope is hardened; s4, a plurality of auxiliary holes are constructed in the area of the foundation pit, and vertical supporting assemblies are installed in the auxiliary holes; s5, downward digging is conducted to a first-stage bottom marking line, transverse supports are installed on the inner sides of the two steel sheet piles, and meanwhile the transverse supports and the vertical support assemblies are connected; s6, downward digging is continued to reach a second-stage bottom marking line, an auxiliary hole is constructed in the second-stage bottom marking line, and a vertical supporting assembly is installed in the auxiliary hole; s7, continuing to dig down to a third-stage bottom marking line; and S8, the vertical support assemblies on the upper side and the lower side are connected through transverse supports till the bottom elevation of the foundation pit is reached, and then construction of the bearing platform is conducted. The device is ingenious in design, the construction safety is improved, and the construction efficiency is guaranteed.
本发明提供一种临河深基坑施工方法，包括以下步骤：S1、平整场地，根据施工图纸放样，在现场进行画线；S2、在基坑的区域外侧施工搅拌桩和钢板桩，在基坑的区域内侧施工灌注桩；S3、在搅拌桩的外侧设置放坡，并对放坡高于水域的部分进行硬化；S4、在基坑的区域内施工多个辅助孔，在辅助孔内安装竖撑组件；S5、下挖至第一级底标线，在两个钢板桩的内侧安装横撑，同时将横撑和竖撑组件连接；S6、继续下挖至第二级底标线，在第二级底标线上施工辅助孔，在辅助孔内安装竖撑组件；S7、继续下挖至第三级底标线；S8、将上侧和下侧的竖撑组件通过横撑连接，直至到基坑底标高，然后进行承台的施工。本发明设计巧妙，提高了施工的安全性，保证施工效率。
