L, (1), using thin wall copper tube instead of thick wall steel pipe. (2), the embedded depth electric motors and position deviation is bigger. (3), cooked water pump in welding corner, on the wall of pipe and horizontal into household electric welding pipe network to link into 90 ° Angle. (4), into the pipe and the basement exterior wall waterproof processing is not good. 2, root cause generator analysis (l), material buyer purchases are not familiar with ac motor national norms, standards, some construction unit obfuscation to reduce costs; Construction manager is not strict or intentional misconduct of the contractor couldn't disagree, do not enforce norms and standards; Supervision of personnel management of the material approach a hole. (2), insufficient coordination with civil engineering and other professional team. (3), no pipe auto spare parts bending machine, or do not use pipe bender, not strong sense of responsibility, convenience to use welding to burn. Tube (4), embedded into the homes of workers don't understand waterproof technology, and is not waterproof, please professional help.

3, preventive measures (l), and must use thick wall copper tube into the household embedded pipe or conform to the requirements of the PVC tube (general wall auto spare parts thickness PVC Φ l 14 more than 4.5 mm, Φ 56 meters to 3 mm). (2), strengthening coordination and cooperation with civil engineering and other related professional, clear outdoor floor level, to ensure that the embedded depth of not less than 0.7 meters. (3), strengthen the contracting team leadership and material buyer relevant laws and regulations of education, supervising personnel should strictly carry out material approach to test the rules, magnetic generator plug hole. (4), embedded steel pipe on the wall of elbow must use pipe bender www.facebook.com/guohong.trading bending, bending are not allowed to welding and welding. Steel pipe after bending, there should be no cracks and significant dent phenomenon, its bending flat program should not be greater than 10% of the pipe diameter, bending radius should not less than wear into the minimum allowable diesel engine bending radius of the cable. (5), good waterproof processing, please professional on-site guidance or by waterproof professional leagues do waterproof processing.
