Open caisson structure applied to narrow zone and construction method of open caisson structure
The invention relates to the technical field of open caisson construction, in particular to an open caisson structure applied to a narrow zone and a construction method of the open caisson structure. The open caisson structure comprises open caisson foundation pits formed by excavating downwards layer by layer, wherein each layer of open caisson foundation pit is an open caisson foundation pit unit, anchoring parts are evenly arranged on the pit wall of each open caisson foundation pit unit, steel reinforcement cages distributed annularly are arranged on the inner circumferential side of each open caisson foundation pit unit, the steel reinforcement cages are fixedly connected with the anchoring parts, annular concrete well walls poured outside the anchoring parts and the reinforcement cages are further arranged on the inner circumferential sides of the open caisson foundation pit units, the annular concrete well walls on the upper layer and the lower layer which are adjacent to each other are stacked up and down, and a concrete sealing bottom is arranged at the bottom of the lowermost open caisson foundation pit unit. The open caisson construction method comprises the steps of positioning, open caisson foundation pit unit excavation, anchoring part installation, reinforcement cage binding, pouring and bottom sealing. Reverse construction is carried out in a layer-by-layer downward mode, construction is more convenient, the structural stability is good, and deflection is not prone to occurring.
本申请涉及沉井施工技术领域，尤其涉及一种应用于狭窄地带的沉井结构及其施工方法。沉井结构包括向下逐层开挖形成的沉井基坑，每层沉井基坑为一个沉井基坑单元，在沉井基坑单元的坑壁上均匀设置有锚固件，在沉井基坑单元的内周侧设置有环形分布的钢筋笼，钢筋笼与锚固件相互固定连接，在沉井基坑单元的内周侧还设置有浇筑于锚固件和钢筋笼外部的环形混凝土井壁，上下相邻两层的环形混凝土井壁上下堆叠，在最下方沉井基坑单元的底部设置有混凝土封底。沉井施工方法包括定位、开挖沉井基坑单元、安装锚固件、绑扎钢筋笼、浇筑以及封底几个步骤。本申请采用逐层向下的方式进行逆向式施工，施工更为方便、结构稳定性较好，不易出现偏斜。
