WSS无收缩双液注浆技术在溶洞处理和基坑止水的应用

Application of WSS Non-shrinkage Two-liquid Grouting Technology in Karst Cave Treatment and Foundation Pit Water Stopping

结合某项目基坑支护止水,工程桩溶洞处理,介绍WSS无收缩双液注浆技术在溶洞处理、基坑止水的方法及工艺,该技术可控制浆液在一定范围内固结土体,减少浆液大量溢出,降低成本,减少对周围建筑物的影响。满足不同的注浆加固要求;同时改变土体物理力学性能,提高土体的承载能力;固化土体以达到地基土加固及起到止水作用的效果。

Combined with the water stop of foundation pit support and the karst cave treatment of engineering piles,the method and process of WSS non-shrinkage double-liquid grouting technology in karst cave treatment and foundation pit water stop are introduced,which can control the grout to consolidate the soil within a certain range,reduce the overflow of a large amount of grout,reduce the cost and reduce the impact on the surrounding buildings.Meet different grouting reinforcement requirements;At the same time,the physical and mechanical properties of the soil are changed to improve the bearing capacity of the soil.Solidify the soil to achieve the effect of foundation soil reinforcement and water stopping.
