摘要
营岔调蓄水池工程是北京2022年冬奥会和冬残奥会张家口赛区的重要组成部分。工程特点是蓄水池开挖深度大,地下水位高,根据地质勘查情况,蓄水池开挖前进行了降水施工,保证了开挖及防渗体系的顺利实施。文章介绍了2022年冬奥会和冬残奥会张家口赛区营岔调蓄水池工程中潜孔锤钻孔降水井施工的具体方法及应用参数。
Yingcha Reservoir Project is an important part of Beijing 2022 Winter Olympic and Paralympic Zhangjiakou Division Area project. The project is characterized by large reservoir excavation depth and high underground water level. Precipitation construction is carried out before the excavation of the reservoir to ensure smooth implementation of excavation and anti-seepage system according to the geological survey condition. The concrete construction method and application parameters of the dewatering well of DTH hammer drilling in Yingcha Reservoir Project of Zhangjiakou Division during 2022 Olympic and Paralympic Winter Games.
