高层建筑工程深基坑支护施工技术分析

Analysis on Construction Technology for Deep Foundation Pit Support in High-rise Building Engineering

深基坑支护是提升高层建筑工程基础稳定性的常用技术,施工难度大。为保证施工中充分支护,文章结合高层建筑工程实际项目分析深基坑支护技术,根据工程实际情况确定支护方案,着重分析支护桩、水泥搅拌桩、降排水处理等技术要点。经基坑监测证实此次施工后基坑各项监测值无报警现象,支护效果理想,希望为同类型工程提供有益的技术经验。

Deep foundation pit support is a commonly used technology to improve the foundation stability of high-rise building engineering,and the construction is difficult.In order to ensure the sufficient support in the construction,this paper analyzes the deep foundation pit support technology in combination with the actual project of the high-rise building engineering,determines the support scheme according to the actual situation of the engineering,and focuses on the analysis of technical points such as support piles,cement mixing piles,dewatering and drainage treatment.The monitoring of the foundation pit proves that there is no alarm phenomenon in the monitoring values of the foundation pit after the construction,and the support effect is ideal,hoping to provide useful technical experience for the same type of engineering.
