Records stress; prohibited in the prestressing due support and embedded parts can not even contact caused by eccentric compression; when supported by the force must be strictly checked and put an end due to the support and the receiving surface is not perpendicular and mutated, leading to the horizontal displacement of deep foundation pit retaining wall and the support continues to increase instability and other phenomena occur, as a result of instability caused by the axial force sensor test, the deformation should be corrected promptly. Repeated examination, note the following: A weld width of not less than all of 8mm, weld shear tension must bear knocked coating and inspection to prevent false welding. B all steel support must be installed in strict accordance with the technical requirements of construction operations. C using bolts then fight steel support, you must wear the uniform, twice tightened bolts shall not be less than two teeth exposed. D fully welded seam, the weld surface of the solder wave requires uniform, not allowed to have steam holes, slag, cracks, sarcoma and other phenomena, the strict implementation of the welding quality inspection system records, after the completion of each process must slag self, through After the inspection, notified by the person in charge of construction personnel inspection and acceptance. Prepared on the basis 1) the owners of the project quality, safety, schedule requirements 2) "Building Foundation Foundation Engineering Construction Quality Acceptance" (GB50202-2002) 3) "Concrete Structures for Construction Quality Acceptance" (GB50204-2002) 4) " Construction site temporary electrical safety technology "(JGJ46-2005) 5) experts will put forward the views of experts 2.3 Compilation Principle 1) ensure that the program is feasible and safe; technical solutions targeted, operational, can shorten the construction period; construction scheme economical and reasonable.
