植物胶溶液在黄壁庄水库副坝防渗墙6~#塌坝段预堵漏灌浆工程中的应用

The application of plant gum solution in the pre-grouting project of anti-seepage wall No.6 collapsed dam in Huangbizhuang Reservoir

黄壁庄水库副坝6#塌坝段坝基由约60m深的第四系各种成因类型的堆积物构成,该坝基多次塌陷,经过2次振冲碎石桩、2次旋喷桩的加固处理,原始地层发生极大的扰动,且成分复杂。在该地层中进行防渗墙预堵漏灌浆施工,钻孔成孔是难点,植物胶溶液的成功应用,基本解决了钻孔成孔的技术难题。

Auxiliary wall No.6 collapsed dam in Huangbizhuang Reservoir is composed of various genetic types of quaternary deposits,which is about 60 meters high.The foundation of this dam has been collapsed for many times,and the original stratum disturbed greatly through twice reinforcements of vibrate gravel pile and twice jet pile reinforcements.The components are complicated.During the construction work of pre-grouting to anti-seepage in this layer,drilling into the hole is the difficult point.The successful application of plant gum solution basically solves the technical problems in drilling into the hole.
