变电站雨水泵站深基坑支护施工技术探讨

A Study of Construction Techniques of Deep Foundation Pit for Storm Water Pumping Station of a Substation

基于变电站雨水泵所处地形、地质及环境情况,对深基坑施工边坡稳定、两侧放坡、板桩支护、井点降水等多种方案进行分析对比,并在基坑施工中,对所采取的两侧钢板桩支护、井点降水、两侧放坡等施工技术进行分析和应用控制,以确保安全施工及最佳技经效能状况下进行深基坑施工。

By comparing several possible construction plans, to analyze the stability of the pit slope to ensure the security before the construction of the pit, while during the operation process, to comprehensively apply such techniques as using pit steel piles to prop the pit, well-point dewatering, sloping on both sides in order to carry on the construction on the basis of security and economic optimization.
