高压喷射灌浆在新疆某水库除险加固中的应用

对坝基深覆盖层的防渗,最常规的方法就是采用混凝土防渗墙,本工程通过高压喷射灌浆与混凝土防渗墙的综合比较,选择高压喷射灌浆和帷幕灌浆对坝基砂砾石层和强风化层进行防渗处理,这对新疆土石坝的防渗采用新的工艺设备及方法带来新的发展空间。简要介绍了高压喷射灌浆设计及高压喷射灌浆施工参数选用,同时简述高压喷射灌浆的施工及在施工中遇到的问题及处理。

Application of High-pressure Jet Grouting in Stabilization for Dangerous Release in a Certain Reservoir of Xinjiang

For the seepage control of the deep layer of dam foundation,the conventional method is to use concrete cutoff wall.Through comparing this method with high-pressure jet grouting,the high-pressure jet grouting and curtain grouting are selected for the seepage control of the sand gravel layer and weathering layer of dam foundation,which would bring a new development space for the seepage control of earth-rock dams in Xinjiang.Here,the design and construction parameters selection of the high-pressure jet grouting are introduced,and the problems in its construction as well as the treating measures for it are also described briefly.
