Inversed construction method for foundation pit
The invention discloses an inversed construction method for a foundation pit. The inversed construction method for the foundation pit is characterized in that a basement structure part is constructed from top to bottom and meanwhile, a main body structure part is constructed from bottom to top; for the basement, construction of horizontal structures of beams, plates and the like of various layers is firstly carried out, and then construction of vertical structures of columns, shear walls and the like of various layers is carried out in an interpenetrating manner; before a vertical bearing structure is not completely finished or does not reach the design strength, the finished permanent load and construction load are both carried and transferred to an engineering pile by virtue of temporarily arranged steel support columns; a special joint box and a fore shaft pipe fill into the joint of adjacent groove widths; partition construction is carried out on each layer along an underground diaphragm wall; the underground diaphragm wall is connected with a basement bottom plate and a floor slab by adopting a rigid connection method, namely a steel connector is buried into an interior wall of the underground diaphragm wall in advance above the reinforcement elevations of the basement bottom plate and the floor slab; when the bottom plate and the floor slab are constructed after the basement is excavated, the bottom plate and the floor slab are directly connected with the underground diaphragm wall into a whole through the steel connector, so as to form a rigid joint.
