Winter construction should be strictly in accordance with the winter construction program for construction, to ensure the construction quality and safety. (8) the longitudinal slope grading techniques based on soil parameters and the actual situation, set up a long slope sprayed concrete slope protection to ensure slope stability. (9) the construction process non-collision steel braces, steel purlin and temporary standoffs piles, beams and other components to ensure that the steel support force in good condition. (10) open-cut excavation of earth: the long arm digging machine excavation. Excavation process in strict accordance with the "hierarchical, step by step, symmetry, balance, limit the" five points, follow the "vertical stratification, vertical partition segment, after the first branch dig" principle construction work. Deep excavation pit bottom left 30cm thick protective layer, trimmed by hand excavation of deep foundation pit. 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.
