分级帷幕止水技术在某船坞改造中的应用
摘要:介绍了一种分级帷幕止水技术在动水压力的抛石坝及粗颗粒地层的应用,阐述了分级帷幕止水技术的原理、工艺、施工方法及止水效果,并通过工程实例,对分级帷幕止水技术的级配干粉料的充填技术和三序孔劈裂注浆技术进行了介绍。分级帷幕止水技术是一种通过工程验证的止水技术,宜在相似工况下推广。
Abstract:Application of graded waterproof curtain technology in riprap dams and coarse-grained strata under dynamic water pressure is introduced, and the principle, technology, construction method and waterproof effect are also presented. Through engineering examples, the filling technology of graded dry powder and the splitting grouting technology of third-sequence holes are introduced in detail. Graded waterproof curtain technology has been proved to be effective by engineering, which is suitable to be applied in practice under similar working conditions.
