旋喷桩在组合帷幕防渗截水中的应用

Application of jet grouting pile in combined curtain anti-seepage water interception

本文以大伙房水库输水工程中一垂直开挖明槽工程为例,介绍由钻孔灌注桩和旋喷桩相互咬合式的组合帷幕在明槽防渗截水中的应用,着重介绍旋喷桩的设计、施工原理、施工工艺及防渗效果分析,为类似工程提供参考。

In the paper, vertical excavation open channel work in Dahuofang Reservoir water conveyance project is adopted as an example. Application of combined curtain of mutually meshing cast-in-situ bored pile and jet grouting pile in open channel anti-seepage water interception is introduced. Jet grouting pile design, construction principle, construction technology and anti-seepage effect analysis are mainly introduced, thereby providing reference for similar projects.
