Project Overview The project is located in Anning grass Town, the Wuhan Iron and Steel (Group) Co., Ltd. to invest in Kunming Iron and Steel, WISDRI Engineering Technology Co., Wuhan Xingyu Management Company Limited Design Engineering Construction Supervision. Local deep excavation depth of about 5-6m, construction pit threats to security, deep excavation construction safety is the top priority of construction, how to ensure security is the focus of deep construction pit construction. . Frame shear wall structure, caps infrastructure, building structural safety rating of 2, fire resistance rating of two. Before paving of soil material, should be prepared to control the level of elevation sign that date from the pit bottom, upward slope along 1m each nail stakes, as a virtual shop soil thickness control elevation. (3) pit backfill should be layered spread out, each virtual height of 250mm, tamper with frog-shaped route back from the pit by ramming the middle, pounding 3 to 4 times. Ram pressure should be pounding a half ram, ram ram phase, trekking linked not leak ram. (4) along the pit should be backfilled around the building at the same time. As the basement larger, longer weekly, to accelerate the pace backfill, backfill can be segmented according to site-specific circumstances, by laying soil, tamp two processes running water construction organization. Made in the construction phase at the stepped section, namely to consolidate the unit to make a high 100mm, 500mm wide steps, and then leveling soil compaction virtual shop together.
