Basement structure semi-reverse construction method for ultra-large deep foundation pit
The invention discloses a basement structure semi-reverse construction method for a super-large deep foundation pit, in the reverse construction stage, a beam plate of an underground structure is adopted as a horizontal support, the first negative layer and the second negative layer of the underground structure can be connected with the beam plate of the underground structure in a central island area during construction, and the horizontal support is integrally formed. In the consequent construction stage, due to the fact that the area of the center island area is greatly reduced compared with the area of an original deep foundation pit, a temporary horizontal inner support is not arranged, and therefore the construction method reduces the installing and dismantling procedures of a traditional temporary horizontal support of the foundation pit, the construction efficiency can be greatly improved, the construction progress can be greatly accelerated, and the construction period can be greatly shortened. The problem that time and labor are wasted when a horizontal support is dismantled and replaced when traditional foundation pit heavy excavation construction is adopted for a super-large deep foundation pit is solved.
本发明公开了一种用于超大深基坑的地下室结构半逆作施工方法，在逆作施工阶段采用地下结构的梁板作为水平支撑，地下结构的负一层负二层施工时都会与中心岛区域的地下结构的梁板衔接在一起，整体构成水平支撑。在顺作施工阶段，由于中心岛区域的面积相较于原深基坑的面积大幅度缩小，所以也不设置临时的水平内支撑，所以，本发明的施工工法减少了基坑传统临时水平支撑安装和拆除工序，能够极大提高施工效率，加快施工进度，节约工期。本发明解决了对于超大深基坑采用传统的基坑大开挖施工存在水平支撑拆除和换撑费时费力的问题。
