Reverse construction and central island type combined foundation pit supporting method
The invention discloses a reverse construction and central island type combined foundation pit supporting method, and relates to the field of foundation pit construction. In order to solve the problemthat the construction period of foundation pit excavation construction is long, the method specifically comprises the following steps that stand column piles and uplift piles are constructed according to the position of a foundation pit; a central island frame structure is reinforced according to corresponding calculation; a basement structure top plate is constructed, one end of the basement structure top plate is supported on a foundation pit enclosure structure, and the other end of the basement structure top plate is supported on the central island frame structure; excavation is carried out downwards to the elevation of the first floor, and a layer of underground plate is constructed and supported on the central island frame structure and the foundation pit enclosure structure; the steps are repeated until excavation is carried out to the bottom of the foundation pit, and a basement structure bottom plate is constructed; and a basement outer wall and a structure outer wrapping column are sequentially manufactured upwards. Compared with a method that in conventional design, excavation of the foundation pit can be carried out under the conditions that a horizontal supporting system needs to be completely formed and the surrounding soil pressure is balanced in foundation pit construction, the construction period of foundation pit excavation construction can be greatly shortened.
本发明公开了一种逆作式和中心岛式相结合的基坑支护方法，涉及基坑施工领域。为了解决基坑开挖施工的工期较长的问题，具体包括如下步骤：根据基坑位置施工立柱桩、抗拔桩；根据相应计算对中心岛框架结构进行加固；施工地下室结构顶板，一端支撑在基坑围护结构上，另一端支撑在中心岛框架结构上；向下开挖至负一层标高，施作一层地下板，并支撑在中心岛框架结构和基坑围护结构上；重复上述步骤直至开挖至基坑底部，施作地下室结构底板；向上依次做地下室外墙和结构外包柱。本发明相对于常规设计中基坑施工需要等水平向支撑体系完全形成且四周土压力平衡的情况下方可进行基坑的开挖的方法而言能够大幅度缩短基坑开挖施工的工期。
