Fabricated open caisson structure and construction method thereof
The invention relates to a fabricated open caisson structure and a construction method thereof. A well wall structure is formed by vertical splicing of multiple segments of annular structures, each segment of annular structure is formed through end-to-end connection and closing of fabricated well piece structures, the adjacent fabricated well piece structures are connected through transverse connecting parts and longitudinal connecting parts to form a complete firm well wall structure, when the depth of the open caisson structure is large, the open caisson structure is segmented, each segmentis composed of one or multiple annular structures, the annular structures in each segment are connected and fixed, a bearing platform structure is arranged in each segment, and is in up and down symmetric, a jack is arranged between two bearing platform structure, during construction, the jacks play a role in pushing downwards the fabricated well piece structures, in the construction process, a center penetrating jack is arranged on the upper end of a steel strand, and is matched with the jacks between the bearing platform structures, sinking of the well wall structure is finished, the open caisson structure is not limited by the self weight, construction speed is high, the environment influence is small, and the cost is saved.
本发明涉及一种装配式沉井结构及其施工方法，井壁结构由多段环形结构竖向拼接组成；每一段环形结构由多个预制井片结构首尾相连封闭组成；相邻预制井片结构通过横向连接构件及纵向连接构件的连接，形成完整牢固的井壁结构；当沉井结构的深度较大时，将沉井结构分段，每段由一个或多个环形结构组成，每一分段内的环型结构相互连接固定，每一分段之间设置承台结构，承台结构上下对称，在承台结构之间放置千斤顶，千斤顶在施工时起到向下顶推预制井片结构的作用；施工过程中，在钢绞线的上端位置设置穿心千斤顶，穿心千斤顶与承台结构间的千斤顶相互配合，完成井壁结构的下沉；该沉井结构不受自重的限制，施工速度快，对环境影响小，节约造价。
