某软土地区深基坑支护施工方案设计

DESIGN OF RETAINING CONSTRUCTION SCHEME FOR DEEP FOUNDATION PIT IN A SOFT SOIL AREA

以某资源回收及废水处理厂为背景,结合现场施工环境和工程地质条件状况,在便于施工和保障施工安全的前提下,使用PHC管桩和粉喷桩等工艺、新材料优化施工,介绍了基坑工程施工的关键技术和工艺要求。该方案在基坑开挖过程中取得了较好的效果,可以为类似的基坑工程的优化设计提供参考。

Taking a recycling and waste water treatment plant as the background,combined with the construction environment and engineering geological conditions,on the premise of convenient for construction and construction safety,the PHC pipe pile and powder spray pile technology,new materials were used to optimize the construction.The key technology and technical requirements in construction of foundation pit engineering was introduced.Through the implementation of the scheme,it shown that the scheme has achieved good results in the process of foundation pit excavation,which could provide a reference for the optimization design of similar foundation pit engineering.
