Foundation pit caisson excavation supporting method
The invention belongs to the technical field of foundation pit excavation supporting, and particularly relates to a foundation pit caisson excavation supporting method. The foundation pit caisson excavation supporting method is used for guaranteeing secondary foundation pit supporting firmness and excavation safety when secondary foundation pit excavation needs to be conducted in foundation pit engineering such as subway stations and municipal administration, the method comprises the steps of carrying out caisson machining; carrying out caisson placing and caisson angle adjusting; carrying outlayered excavation of a foundation pit, and pumping and draining accumulated water in the excavation process; knocking a hammering cap to enable a caisson to sink in place, after the caisson sinks tothe layered position, staring excavation of the next layer of earthwork, and achieving circulating footage; when the caisson sinks to the designed position, stopping excavation; building brick moldson the inner side face of the caisson; cutting off diagonal bracings and inclined bracings on the upper side of the caisson, constructing a waterproof coiled material layer, mounting reinforcing steelbars, and pouring concrete; and completing plugging of a dewatering well. Compared with other foundation reinforcing methods, the method is more suitable for small working faces and conditions with complex geological conditions, construction is easy, the effect is obvious, the construction period is short, and the cost is low.
本发明属于基坑开挖支护技术领域，具体涉及一种基坑沉箱开挖支护方法，用于在地铁车站、市政等基坑工程中需要进行二次基坑开挖时，保证二次基坑支护牢固和开挖安全，包括沉箱的加工，放置并调整沉箱角度，基坑的分层开挖、开挖过程中的积水抽排，敲击锤击帽使沉箱下沉就位，沉箱下沉到分层位置后，开始开挖下一层土方，实现循环进尺；沉箱下沉至设计位置时停止开挖，在沉箱的内侧面砌筑砖模，切割掉沉箱上侧的对撑和斜撑，施做防水卷材层，安装钢筋，浇筑混凝土，完成降水井的封堵。本发明阐述的方法比其他地基加固方法更适用于小型工作面，地质条件复杂的条件，且施工简单，效果明显，工期较短，成本较低。
