单管高压旋喷桩在特殊环境条件下的应用

Application of Single Tube High Pressure Jet Grouting Pile in Special Environmental Condition

针对有高压线、有限高或施工场地狭窄、多头搅拌桩防渗墙无法施工的区域,提出采用单管高压旋喷桩防渗墙防渗方案,介绍了防渗方案的设计及施工方法,经效果检查,满足设计要求;该防渗墙施工设备体积小、重量轻、作业高度低,适用于各种条件下施工,施工简单,施工速度快,对变形的适应性强,防渗效果好。

With taking consideration of high voltage line,height limit or narrow construction site and construction area in which cutoff wall of multi-head stirring pile cannot be carried out,the plan of single tube high pressure jet grouting pile to prevent seepage is put forward.The designand construction method of seepage prevention is introduced,which meets requirement after inspection.This cutoff wall is characterized by small volume and light weight of construction equipment,low operation height,strong adaptability to deformation,good anti-seepage effect,which is suitable for various conditions of construction and achieves simple construction with high speed.
