Electric Works 一、 Technological process Diagram 二、 Open–pipe installation The position and elevation are correct, and the grounding is good Draw integrated drawing and detail of pipeline grounding Installation on crane span structure slot Correct level, installation on hanger frame, fire protection treatment of through-wall and floor, clearance with other special pipeline Draw integrated drawing, installation drawing of hanger frame, and detail of fire protection treatment Threading distribution Wiring correct error, conducting wire with rinsing tin, conducting wire with damage Strictly carry out wiring drawing, rinsing tin, pay attention to protecting the wire when threading Cable lay Straight cable, firm fixing, cable bending, and identification Implement requirements relating to drawing and specification Soldered dot Ground resistance at welded position, and the surface at welded point is smooth and full Test the ground resistance of welded position after finishing the welding. Appliance installation The position is correct and installed firmly, the appearance is good. Arrange the plan installation according to electromechanical drawn integration diagram and surface appliance Debugging Operating stability, reliability, and insulating shake-measure in system Work out the special debugging plan 三、1、pipes in the project adopt the open-lay technology of galvanized steel pipe. （1）（2）（3）Pipes that the pipe diameter is less than 20mm may adopt a palm simmer pipe machine. Pipes that the pipe diameter is more than 25mm may use a hydraulic simmer pipe machine (or special simmer pipe machine). The concavity at simmering bends should accord with specifications and regulations. （4）The size of pipe needing to cut should be exact. Put pipes on the center of pressure jaw, and keep fractures even. At fracture, fill the inner or outer of pipe orifice smoothly without any burr. The scrap iron in pipe should be cleaned clearly. （5）Select correspo
