电气埋管施工工艺细则Electrical conduit construction technology rules1. 严禁使用电焊、气焊割管。Strictly prohibited in using gas and electric welding cutting conduit.2. 严禁将脚手架作为电缆管使用。Strictly prohibited in using the folder as electrical conduit.3. 锈蚀严重的钢管不得使用;钢管弯制或安装前应将管口及管内杂物清扫洁净,并除去毛刺。 Exist serious corrosion conduit is not allowed used; the mouse of the conduit as the inner part the debris must be removed before bending or installation3. 电缆管切割采纳手工锯或切割机进行切割,并保证切割面平整且不倾斜;切割后必须立即将管口毛刺打磨洁净,并打磨管口成喇叭型。Cutting for the conduit adopting in manual saw or machine, and ensure the cutting surface smooth and not tilt; burring after cutting must be immediately, and polished type nozzle into horn.4. 电缆管的弯曲半径 R≥10D(电缆管外径);弯曲角度≥90°,并尽可能减少 90°弯头;电缆管弯制不得出现明显的凹瘪、裂纹、折皱 ,钢管弯扁程度≤(电缆管外径)。Bending radius R ≥ 10D (here D is conduit out diameter);Bending Angle ≥90 °, and as less as possible the 90 °elbow; conduit bending cannot appear obvious concave, crack, wrinkle, flat steel tube bending flat level ≤ D (here D is conduit out diameter).6.电缆管安装时,每根电缆管弯头数量不得超过 3 个,90°弯头不得超过 2 个(埋管长度≥12 米,不得多于 2 个弯头;12 米≥埋管长度≥8 米,不得多于 3个弯头;直管埋设不得大于 30 米)超过上述标准须增加转接盒。When installation conduit, the amount of each conduit elbow shall not exceed 3, elbow with 90 °shall not be more than 2;the conduit length ≥12m, shall not be more than two elbow; The length of the conduit that changed between 8m and 12m , shall not be more than three elbow; straight shall not be more than 30 meters;If exceed the standard more than the standard must...
