Rain and sewage diversion transformation method for soft soil foundation
The invention relates to the technical field of urban drainage pipe network transformation engineering, in particular to a transformation method for rain and sewage diversion of a soft soil foundation, which is implemented in a mode of simultaneously carrying out drainage channel cofferdam diversion and soft soil foundation pit excavation construction. The cofferdam disclosed by the invention can be quickly constructed in the sewage discharge channel, the structure is simple and practical, the construction is easy, and the formed cofferdam has higher stability compared with the existing soil cofferdam or earth rock cofferdam; in the foundation pit excavation process, a supporting structure combining the cement mixing piles with the high-pressure jet grouting piles is adopted, the undesirable phenomena of side wall quicksand, pit bottom piping, large foundation pit deformation, large pile body stress and the like in the excavation project can be avoided, and construction machinery can work above the foundation pit conveniently. And drainage of the drainage channel cofferdam and excavation of the soft soil foundation pit are synchronously carried out, so that the construction period of rain and sewage diversion reconstruction operation is remarkably shortened.
本发明涉及城市排水管网改造工程技术领域，具体为一种软土地基的雨污分流的改造方法，该方法采用排污渠围堰导流及软土基坑开挖施工同时展开的方式实施。本发明的围堰可以在排污渠内快速构建，结构简单实用，易于施工，且形成的围堰较现有的土围堰或土石围堰相比有较高的稳定性；基坑开挖过程中采用水泥搅拌桩结合高压旋喷桩的支护结构，可以避免开挖工程中出现侧壁流砂、坑底管涌、基坑变形大及桩身受力大等不良现象，便于施工机械在基坑上方作业。排污渠围堰导流及软土基坑开挖同步开展，显著缩短了雨污分流改造作业的工期。
