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. 13, "Building Safety Production Supervision and management practices," the Ministry of Construction Decree No. 13 of 14, "construction safety inspection standards" JGJ59-99 15, "construction earthwork safety technical specifications" JGJ180-2009 16, "Building Foundation Pit Monitoring Technology specifications "GB50497-2009 17," more dangerous part of the project safety management "build quality (2009) 87 Guangxi Construction Engineering Group Fifth construction limited liability company Jingtai Gangnam 1 #, 2 # Building earthwork open dig deep excavation safety special construction solutions company quality, environmental, occupational health and safety policy: careful construction, customer satisfaction, energy saving, environmental harmony, health and safety, prevention, good faith compliance, continuous improvement. 318, nation-building construction quality inspection assessment of production, civil construction and construction safety standard compliance with the relevant provisions 19, Fangchenggang City, the relevant documents and regulations 20.
