浅析迪拜哈斯彦清洁燃煤电厂陆上深基坑降水施工技术

Construction Technology of Onshore Deep Foundation Pit Precipitation in Hasyan Clean Coal-Fired Power Plant in Dubai

海侧4 m直径GRP深基坑降水为海外首例,施工难度大,工期紧,同时迪拜市政对HSE要求极为严格,为满足要求,本工程采用了明排结合深井点降水的施工工艺。论文对该工程降水施工关键点进行探讨。本工程施工在工艺可行性、施工安全性、节约成本方面都取得良好的效果。

The dewatering of 4 m diameter GRP deep foundation pit on the sea side is the first overseas case,with great construction difficulty and tight construction duration.At the same time,the DM has extremely strict HSE requirements.In order to meet the requirements,the construction process of open drainage combined with deep well point dewatering is adopted in the project.This paper discusses the key points of the dewatering construction.The construction of the project in the feasibility of technology,construction safety,cost saving have achieved good results.
