Novel underpinning construction method for steel pipe under existing building foundation
The invention relates to a novel underpinning construction method for a steel pipe under an existing building foundation, and relates to the field of foundation construction. The novel underpinning construction method comprises the following steps of S1, carrying out preparation work; S2, piling; S3, drilling; S4, installing the steel pipe; S5, reinforcing the steel pipe; S6, repeating the operations from S3 to S5; S7, reinforcing and supporting; and S8, finishing. The novel underpinning construction method has the effects that the supporting strength of the steel pipe is improved, then the load strength of the steel pipe is achieved, the operation structure is simple and materials are environmentally friendly while the efficient underpinning of a steel column is ensured, and the construction cost is reduced.
本申请涉及一种既有建筑地基基础下钢管新型托换施工方法，涉及地基施工的领域，其包括如下步骤，S1、准备工作；S2、打桩；S3、钻孔；S4、安装钢管；S5、加固钢管；S6、重复S3‑S5操作；S7、加固支撑；S8、完工。本申请具有提升对钢管的支撑强度，进而实现钢管的荷载强度，确保托换钢柱高效进行的同时，操作结构简单，材料环保，具有降低施工成本的效果。
