Construction Organization Design of Foundation Pit Row Pile Support and Dewatering of Building
The total land area of the project is 50801.31 square meters. The plot is composed of four plots, namely, No. 11, No. 12, No. 13 and No. 14. There is a planned road (XX Road) between No. 11, No. 12 and No. 13, No. 14. The site is flat and convenient for transportation. According to the geological survey report and excavation drawing, the excavation depth of the foundation pit is 16.53m~18.03m (relative to the original landform elevation) (the excavation depth of the foundation pit in the D-D support section is the deepest); On the north side of Building 2 # (outside the B-B support profile), the municipal greening slope soil outside the site is about 1~2m higher than that inside the site (relative to the original landform elevation). According to the Code for Investigation of Geotechnical Engineering (GB50021-2001), 2009 edition, the importance level of the project is Level I, the site level is Level II, the foundation level is Level II, and the geotechnical investigation level is Level A. The foundation pit support and dewatering works of this project were designed by XX Survey, Design and Research Institute Co., Ltd. The scheme has been demonstrated by experts and confirmed as qualified. The designer has made a comprehensive reply to the review comments.
