基坑盆式挖土法与多阶梯基坑抽渗结合降水施工技术

Construction Technology of Combining Basin Type Excavation Method of Foundation Pit with Multi-step Foundation Pit Drainage

以甘肃天水中深财富中心项目深基坑土方开挖为例,阐述了盆式土方开挖在深基坑施工中的应用,结合复杂地质环境下多阶梯基坑“抽渗”降水的应用,通过现场的科学组织与管理,有效缩短了建设工期,降低施工风险,顺利完成了深基坑的土方开挖。

Taking the deep foundation pit earthwork excavation of Gansu Tianshui Zhongshen Wealth Center Project as an example,the application of basin type earthwork excavation in the construction of deep foundation pit is expounded.Combined with the application of multi-step foundation pit"pumping and seepage"precipitation under complex geological environment,through the scientific organization and management of the site,the construction period is effectively shortened,the construction risk is reduced,and the earthwork excavation of deep foundation pit is successfully completed.
