跌水井逆作法及顶管的施工技术

Water-dropping well reverse method and pipe-jacking construction technology

结合工程实例,介绍了跌水井逆作法及顶管的工作原理,对测量放线、土方开挖、钢筋绑扎、搭设脚手架、底板及防水施工等跌水井逆作法施工技术进行了阐述,并探讨了顶管的施工要点,以降低施工成本,提高施工效率。

Combining with engineering examples,the paper introduces water-dropping well reverse method and pipe-jacking construction princi-ples,describes water-dropping well reverse construction technologies including measurement sampling,earthwork excavation,steel binding,set-ting scaffold,bottom board and waterproofing construction and so on,and explores pipe-jacking construction points,with a view to reduce con-struction cost and improve construction efficiency.
