Method for excavating and constructing large-area basement
The invention discloses a method for excavating and constructing a large-area basement. The method is characterized in that the basement is divided into a middle region and an edge region. The middle region is circular or oval and the area of the middle region ranges from 300 m<2> to 500 m<2>. After a lattice steel column and a basement enclosure wall are constructed, a concrete top board of the edge region is constructed firstly and the concrete top board is annularly supported in the basement; then, the middle region of the basement is constructed; a circular or oval capping beam is arranged at the top of the middle region of the basement; a temporary enclosure wall is arranged at the lower portion of the capping beam; earth excavation of the middle region is performed layer by layer; when earth of the middle region is excavated to the bottom elevation portion of a bottom board of the basement, the bottom board of the basement is poured and then structural floor slabs of the middle region are poured layer by layer from bottom to top; after the structural floor slabs of the middle region of the basement are constructed, the edge region is constructed; and a construction method implemented from top to bottom is adopted in construction of the edge region and concrete side walls and floor slabs of the basement are poured as soon as a layer of earth is excavated.
