Deep foundation pit construction method for reducing underground space deformation
The invention relates to a deep foundation pit construction method for reducing underground space deformation. The method is suitable for construction of all deep foundation pits with length-width ratios larger than 2.5 and total lengths larger than 200 m and underground spaces. The method is characterized by including the following steps of dividing a deep foundation pit into three areas in the long side direction through a temporary enclosure structure in the middle after an outer enclosure structure is completed for the deep foundation pit, digging earthwork of the areas on the left side and the right side, constructing inner supports, and constructing earthwork, inner supports and a basement of the area in the middle after detaching the inner supports of the areas on the left side and the right side and sealing the tops of basements. By means of the method, the deformation of the deep foundation pit and the underground space can be greatly reduced, and especially for the middle area, the overall construction quality is improved.
