大直径冲孔灌注桩掉锤打捞施工新技术

New Technology During the Construction of Large Diameter Hammer Out Fishing

大直径冲孔灌注桩施工过程中,经常出现掉锤现象,而桩机掉锤打捞因桩长、地质等原因打捞施工十分困难,严重影响工期、增加施工成本。文章结合工程应用实例,介绍一种新的掉锤打捞处理施工技术,希望能为类似工程情况提供一种解决新思路。

Large diameter punch filling pile construction process, often appear drop hammer, salvage for pile length and pile machine drop hammer, the geological reasons such as salvage construction is very difficult, seriously affect the construction period, increase the construction cost. Combining with engineering examples, this paper introduces a new construction technology in the drop hammer salvage, hopes to similar engineering provides a new train of thought of solving condition.
