配管及穿线工作是建筑电气工程中最基础的工作,在施工中常出现许多质量通病,下面介绍这些质量通病及防治方法。一、配管、穿线常出现的质量通病1.钢管配管的通病(1)钢管及接线盒质量不符合要求。(2)钢管弯曲半径、弯曲数量及接线盒位置不当,以致损伤导线 Plumbing and threading work are the most basic tasks in building electrical engineering. Many common defects in quality often occur during construction. The following describes common quality defects and prevention methods. First, piping, threading quality problems often appear 1. Pipe common problems (1) steel pipe and junction box quality does not meet the requirements. (2) The bending radius, the number of bends, and the improper position of the terminal box cause damage to the wire.
