When the supporting structure distortion exceeds the allowable value, but relatively small, no large deformation, should be within the deformed portion encryption support, and increase the monitoring frequency. b, when the supporting structure deformation is too large, there are premonitory, and obviously tilted, it can be immediately set up between the bottom of the pit and the pit wall add braces to stabilize. c, when the supporting structure because of insufficient pile embedded solid depth, so pour or skirting instability, should immediately stop within the supporting piles of earth excavation, pile in front of the pile of sand bag into the back pressure or short pile retaining pile in passive zone reinforcement. 4) When there are old buildings around the pit, shall be based on the actual situation in the pre-excavation before reinforced. 5) When the excavation of the surrounding buildings severe cracking, tilt, should immediately organize personnel evacuation, and support immediate reinforcement or demolition, also reported to higher authorities. 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.
