管内配线工程技术交底-建筑安装.doc

一、 施工准备
（一） 作业条件
根据现行国家标准《建筑电气工程施工质量验收规定》(GB50303-2002)的规定:管内穿线在建筑物抹灰、粉刷及地面工程结束后进行,穿线前应将电线保护管内的积水及杂物清理干净。但针对建筑电气安装项目逐渐增加,管内穿线的工程量随之增大,为配合工程整体同步竣工,管内穿线可以提前进行,但必须满足下列条件:
1、 混凝土结构工程必须经过结构验收和核定。
2、 砖混结构工程必须初装修完成以后。
3、 作好成品保护,箱、盒及导线不应破损及被灰浆污染。
First, construction preparation
(A) Operating conditions
Under the current national standard, "the quality of electrical engineering in construction inspection requirements" (GB50303-2002) provides: pipe threading in the building plastering, painting, and after the end of the ground works carried out before threading wire protection tube should be inside the water and debris clean up. Electrical installation for construction projects, but a gradual increase in pipe threading capacity increase with the project, in line with the overall synchronization project completion, pipe threading can advance, but must meet the following conditions:
1, the structure of concrete structures must be acceptance and approval.
2, brick works must be completed after the beginning of the decoration.
3, prepare final product, cartons, boxes and wires should not be damaged and contaminated by mortar.
