电气埋管施工工艺细则
Electrical conduit construction technology rules
严禁使用电焊、气焊割管。
Strictly prohibited in using gas and electri得留有间隙；连接套管与电缆管两侧均匀电焊4点，并用黑胶布缠绕封实；
When coupling, there shouldn’t gap between the two conduit and the counterpart malocclusion is less than 2 mm, counterpart seam should be in the middle of the socket, and the both sides along the circumferential welding sealing, partial cannot welding must use black tape winding sealing with fastened iron wire;
9． 电缆管不得在外壁直接点焊加固，加固采用铁丝绑扎或煨制钢筋成环钩加固、切割20~30mm套管套至固定点进行，固定间距：φ15~~，φ25~~，φ40~~，φ65以上不不小于3米。
Pot welding reinforce can’t be allowed outside the wall of conduit directly, a available steel bar will be made into a ring hook, and then cutting 20 ~ 30 mm one end fasten to conduit another one stable point or iron wire colligation
fixed spacing: φ15mm ~ 20mm is ~ m, from 25mm to 32mm is ~ meters, 40mm ~ 50mm is ~ meters, exceed 65mm not more than 3 meters
10．电缆管与接线盒旳连接可采用焊接和丝扣连接，：电缆管伸入接线盒3~6mm
管口用黑胶布包扎结实，接线盒内用湿棉纱、破布填实；外部用黑胶布缠绕，以避免水泥沙浆进入。
Welding and threaded can be used for the connection between electrical conduit and sockets, electrical conduit are putted into the sockets 3 ~ 6 mm
The mouse of the conduit with black adhesive bandage, internal parts of the socket filled with a wet cotton yarn ,cloth; External with black tape winding, in order to prevent cem
