Foundation pit inclined support system and foundation pit inner support construction method
The invention discloses a foundation pit inclined support system and a foundation pit inner support construction method. The foundation pit inclined support system comprises a side wall enclosure structure of a foundation pit, a top beam connected with the side wall enclosure structure, a steel pipe inclined strut and a bracket, wherein the bracket is fixedly arranged on a foundation pit bottom plate, the steel pipe inclined strut is arranged between the side wall enclosure structure and the foundation pit bottom plate in an inclined strut mode, one end of the steel pipe inclined strut is fixedly connected with the top beam, and the other end of the steel pipe inclined strut is fixedly connected with the bracket. The foundation pit inner support construction method is based on the foundation pit inclined support system and comprises the following steps of (1) mounting a long type inclined strut; (2) excavating reserved soil and constructing a residual bottom plate; (3) mounting a short type replacement support and removing the long type inclined strut; and (4) constructing a main body structure and removing the short type inclined strut. The foundation pit inclined support system and the foundation pit inner support construction method have the advantages that supporting materials can be recycled, so that the supporting rigidity is increased; and the support construction period is short, the reserved soil excavation difficulty is reduced, the construction cost is reduced, and the construction safety is improved.
本发明公开了一种基坑斜向支撑体系及基坑内支撑施工方法，该基坑斜向支撑体系包括基坑的侧壁围护结构、连接侧壁围护结构的冠梁、钢管斜撑、牛腿；牛腿固设在基坑底板上，钢管斜撑斜撑在侧壁围护结构与基坑底板之间，钢管斜撑的一端与冠梁固定连接且另一端与牛腿固定连接。该基坑内支撑施工方法基于基坑斜向支撑体系，包括：(1)长型斜撑安装；(2)开挖预留土及施工剩余底板；(3)安装短型换撑及拆除长型斜撑；(4)施工主体结构及拆除短型斜撑。它具有如下优点：支撑材料可回收重复利用，增加支撑刚度；支撑施工周期短，预留土开挖难度降低，施工成本降低，提高施工安全性。
