Super large super deep basement ground pit construction method
The invention relates to a super large super deep basement ground pit construction method comprising the following steps: using underground diaphragm wall and drilling perfusion campsheds to divide a whole body into three parts, wherein two side subareas are simultaneously in consequence construction, and a middle zone is constructed later so as to serve as a buffer area; in a construction process, an annular support and change-support beams can transfer horizontal forces received by the ground pit to the buffer area, thus ensuring safety and stability of the ground pit in an excavation process; after two side subareas basement structure construction is completed, the buffer area basement ground pit is excavated, and a first-support-then-excavation principle is followed in the excavation process, after the buffer area basement structure construction is completed, change-support beams in each layer are dismounted in sequence from top to bottom. In the construction process, the method uses the annular support and the change-support beams to cancel the horizontal force received by the ground pit, thus ensuring whole stability of the ground pit. The method can solve the construction safety problems of the super large super deep ground pit, can greatly reducing technical and construction difficulties of the super large ground pit, and thus improving ground pit construction efficiency.
