Construction method of deep foundation pit concrete support servo system
The invention belongs to the technical field of deep foundation pit engineering construction, and discloses a construction method of a deep foundation pit concrete support servo system, which comprises the following steps of: S1, pre-burying a steel plate on the side wall of an underground diaphragm wall; s2, the concrete servo supporting structure is hoisted below the concrete fixed supporting structure; s3, a servo jack is installed on the concrete servo supporting structure, one end of the servo jack abuts against the concrete servo supporting structure, and the other end of the servo jack abuts against the embedded steel plate; s4, loading the servo jacks in a graded manner; and S5, a gap between the concrete servo supporting structure and the underground diaphragm wall is subjected to joint filling treatment. The concrete servo supporting structure is arranged in the deep foundation pit in a suspended mode, supporting force is loaded to the servo jacks on the servo supporting structure in a staged mode, pressure is continuously applied to the underground diaphragm wall, the influence of displacement of the underground diaphragm wall on the safety of the deep foundation pit is actively controlled, and the risk of foundation pit collapse caused by excessive deformation of the underground wall during excavation of the deep foundation pit is reduced.
本发明属于深基坑工程施工技术领域，公开了一种深基坑混凝土支撑伺服系统的施工方法，包括：步骤S1、在地下连续墙侧壁预埋钢板；步骤S2、将混凝土伺服支撑结构吊装于混凝土固定支撑结构下方；步骤S3、在混凝土伺服支撑结构上安装伺服千斤顶，伺服千斤顶一端与混凝土伺服支撑结构抵接，另一端与预埋钢板抵接；步骤S4、分级加载伺服千斤顶；步骤S5、对混凝土伺服支撑结构与地下连续墙间的空隙进行填缝处理。本发明通过在深基坑中悬吊设置混凝土伺服支撑结构，通过向伺服支撑结构上的伺服千斤顶分级加载支撑力，对地下连续墙持续施压，主动控制地下连续墙位移对深基坑安全的影响，降低深基坑开挖地墙变形过大导致基坑坍塌的风险。
