Lifting handling equipment, Shandong reconnection map, special lifting equipment

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. VI construction stakeout and construction monitoring I. Surveying 1, before the start of the detection by Wei instrument, level and ruler, to minimize measurement error. 2, in order to coordinate system provided by the Party establishment plane control network, including control baselines, axes and horizontal reference point, good control and measurement check axis. By precisely measuring the size of the network to ensure that the control plane, the angle of compliance with regulatory requirements. 3, as a control measure for the building and check the positioning axis, measuring the amount of earthwork positioning actinomycetes, set up the goal plate and emit ash pit excavation line, the upper edges and bottom edges and level mark, and the establishment of parties Grid. 4, the control points are located in the wall, the inner periphery of the building and away from the excavation pit edges range 2 ~ 4m layout, control points arranged in a straight line, in order to retest. The establishment of horizontal control points located around the fence stakes protection, and set up eye-catching signs, stakes after completion of the project to save. 5, test line: from posterior axis by qualified, competent leaders and relevant departments to draw notice to Party inspection line, after receiving notice of qualified test line, put to official use.
