排桩+内支撑+锚杆组合结构综合支护施工技术

Construction Technology for Comprehensive Support of Row Pile+Internal Bracing+Anchor Rod Combined Structure

结合海口中心基坑工程实际,介绍了以排桩+内支撑+锚杆组合结构作为支护的施工技术。针对海口特殊的地质水文条件及工程周边环境,重点介绍了该工程开挖、支护、降水全过程的施工要点。根据施工过程中的基坑监测数据显示结果,基坑变形满足设计要求,验证了施工技术的合理性。

Combined with the foundation pit engineering practice of Haikou Center, the construction technology of row pile＋internal bracing＋anchor rod combined structure for foundation pit support has been introduced. Considering the special geological and hydrological conditions of Haikou and its surrounding engineering environment, the key engineering construction points of excavation, support, and whole process of dewatering have been empathically introduced in this paper. According to the monitoring data results in process of foundation pit construction, the deformation of foundation pit met the design requirements, which verified the rationality of construction technology.
