Basement structure construction method combining separate warehouse building and alternate warehouse dismantling
The invention discloses a basement structure construction method combining separate warehouse building and alternate warehouse dismantling, which comprises a subway protection area and a cultural relic protection area, and is characterized in that foundation pits are excavated on one side in zero-distance contact with the subway protection area and one side adjacent to the cultural relic protection area, and a basement structure is constructed; the whole foundation pit is quadrilateral and avoids a subway protection area and a cultural relic protection area. The method comprises the following steps that firstly, temporary underground diaphragm walls are arranged according to the protection ranges of the subway protection area and the cultural relic protection area, and the interior of the foundation pit is subjected to bin division design; secondly, a permanent underground diaphragm wall is supported on the periphery of the foundation pit, and a temporary underground diaphragm wall is constructed in the foundation pit for foundation pit separation; and thirdly, the branch bin foundation pits are excavated to the bottom elevation of the first inner support at the same time, and then construction of the top beams and the first inner support of the branch bin foundation pits is completed. According to the construction method, the deformation influence on a subway protection area and a cultural relic protection area in the basement structure construction process is effectively reduced, the construction period is shortened, and the safety of operators is high.
本发明公开了一种分仓搭建—跳仓拆除相结合的地下室结构施工方法，包括地铁保护区和文物保护区，在零距离接触所述地铁保护区一侧及紧邻所述文物保护区一侧开挖基坑并施工地下室结构，基坑整体呈四边形且避让地铁保护区和文物保护区，包括以下步骤：步骤一、根据地铁保护区和文物保护区的保护范围设置临时地下地连墙对基坑内部进行分仓设计；步骤二、在基坑外围支护永久地下地连墙，在基坑内部施工临时地下地连墙进行基坑分仓；步骤三、各分仓基坑同时开挖至首道内支撑底标高，再完成各分仓基坑的冠梁及首道内支撑施工。该施工方法有效减小了地下室结构施工过程中对地铁保护区及文物保护区的变形影响，且缩短了施工周期，操作人员安全性高。
