抓斗法连续防渗墙施工技术应用探讨

摘要

Underground concrete diaphragm wall as the city underground civil air defense engineering is widely applied and also widely used in the large scale water conservancy and hydropower engineering practice.Its construction needs the conditions and highly required process.In this paper,through an example of combining reinforcement construction for a water conservancy project,taking the construction of cutoff wall technology,construction scheme,construction process and construction method are discussed.The effect of the anti-seepage reinforcement shows that the construction technology adopted is feasible and worthy of popularization.%地下混凝土防渗墙在城市地下人防工程中应用比较普遍，被广泛地应用到大型水利水电坝体具体工程中，其对施工所应具备的条件以及工艺要求较高。文章通过结合某水利枢纽工程除险加固施工实例，采取抓斗法连续防渗墙施工技术，探讨了该工程施工方案构想、施工程序及施工方法，从该防渗加固效果表明，所采取的施工技术的可行性及其推广性。
