卵形消化罐深基坑维护方案的优化

Optimization of Maintenance Scheme for Deep Foundation Pit of Egg-shaped Digester

在某污水处理厂二期工程两座卵形消化罐的施工中,根据构筑物的建造特点并结合一期工程的施工经验,合理地利用工程桩承担部分侧向土压力,优化了深基坑维护方案,从而大大减少了临时设施工程量,并取得了较大的经济效益。

During the construction of two egg-shaped digesters in the second-stage project of a WWTP, based on the construction characteristics of the structures and the construction experience of the first-stage project, the engineering piles were rationally used to bear part of the lateral pressure of soil. The maintenance scheme for deep foundation pit is optimized, thus the work volume for provisional facilities is greatly reduced, and the great economic benefit is obtained.
