顶进框架桥基坑降水施工技术

Jacking Frame Bridge Foundation Excavation Dewatering Construction Technology

以天津市九园公路下穿京沪铁路工程为实例,对降水设计和施工要求进行了探讨,利用高压旋喷桩止水帷幕,管井降水,辅以理论计算、变形监测等措施,确保了工程进度及铁路安全。

Taking Tianjin Nine Park Road crossing under the Beijing to Shanghai railway project as an example,the design of dewatering and construction requirements are discussed,by using the high pressure jet grouting pile waterproof curtain,tube well dewatering,supplemented by theoretical calculation,the deformation monitoring and other measures,to ensure the project progress and railway safety.
