| Abstract:The foundation pit support for the miners’ apartment building of Huangling Mining Group is designed with the excavation depth of 8.37m. Since the security level for the south side is classified as the first grade, and slope grading is not permitted, the soldier pile + prestressed anchor grid is designed for support. For the east, west and north sections, the security level is classified as the second grade, and sloping is permitted; thus, slope grading+the soil nail wall support is designed for support. For dewatering, tube wells outside the pit is combined with the water ditch collection and drainage in the pit. The design of different support and dewatering plans are introduced. At the same time, the construction specifications for soil nailing walls, support piles, prestressed anchor cables, dewatering wells and observation wells are introduced. |
