& emsp;& emsp; electrical engineering、pipeline project、The process method used during the installation of HVAC engineering is related to engineering quality。Under the standard framework of the installation project，Different units have their own construction technology and optimization measures。Installation is not only reflected in quality，Consider from the perspective of aesthetics，But installation engineering，Especially concealment projects and embedded projects，There are often problems，This also leaves a hidden quality hazard for the next process。
& emsp; & emsp; 1. The embedded box does not clean up **、No rust in the steel box，Pipe inlet box is too long，Variality of the flatness of the wall
& emsp; & emsp; 2. The exterior wall flexible waterproof sleeves are irregular
& emsp; & emsp; 3. ground bus welding slag，Cross -matching method error，No matching length requirements
& emsp; & emsp; 4. The electrical catheter did not take compensation measures through the seam of the telescopic structure。
& emsp; & emsp; 5.，Unpacking of the mouth，The insulation layer of the power cord is prone to damage
& emsp; & emsp; 6. Fire prevention、Passing the wall without a tube for the water pipe pipe，Lack of brackets of vertical pipelines。
& emsp; & emsp; 7.，Located above the cable bridge。
& emsp; & emsp; 8. Welding pipe、PVC two different materials of the ducts of the two different materials are directly connected。
& emsp; & emsp; 9.，Four -pass box instead of two -way box，Welding pipes and wiring box are irregular。
& emsp;& emsp;Before entering the field, check the original water and electricity of the house，Refining the construction of hydropower entry。
& emsp; & emsp; Hydropower construction is mainly divided into hydropower technology、Confirmation of switch socket Putting line、slot punching、fixed dark box electric box、Water pipe laying、Electric box installation、Ten parts of the acceptance of water and electricity concealment engineering。
& emsp; & emsp; ◆ Before entering the field，First is a hydropower base。Designer、Project Manager、Leader of the Hydropower Team、The supporting construction party can go on the spot according to the construction map。
& emsp; & emsp; ◆ Hydropower construction supporting project mainly includes kitchen cabinet drawings、Sanitary Ware Model、Smart weakness、Water treatment equipment, etc.。
& emsp; & emsp; ◆ According to the height of the switch socket，Bin two standard horizontal lines pop up
& emsp; & emsp; ◆ According to the complete bomb line，Height of the horizontal line:
& emsp; & emsp; switch height 130cm，
& emsp; & emsp; socket height 30cm from the ground。
& emsp; & emsp; → Make sure that all switches and sockets are on the same level
& emsp; & emsp; ◆ In the unit scope，The height difference must not exceed 3mm，The horizontal line error of the entire house must not exceed 5mm (special location needs to be constructed as required)
& emsp; & emsp; ◆ The position of all switch sockets is clearly indicated at the scene，and go to the scene with the owner，Confirm the switch socket。
& emsp; & emsp; ◆ Positioning line
& emsp; & emsp; single tube slot width is 3cm
& emsp; & emsp; double tube slot 6cm
& emsp; & emsp; ◆ Guarantee between the line tube and the groove，Space distance of filling cement，reaches 1.5cm，Make sure that the wall flood will not crack after brushing。
& emsp; & emsp; ◆ slot punching
& emsp; & emsp; φ16 tube slot depth is not less than 3.16 tube cm
& emsp; & emsp; φ20 tube slot depth is not less than 3.5cm
& emsp; & emsp; ensure that the thickness of the cement mortar is not less than 1.5cm。
& emsp; & emsp; ◆ Note:
& emsp; & emsp; ① The wall surface is not allowed to open a horizontal slot
& emsp; & emsp;
& emsp; & emsp; ③ Putting on the terrace ground
& emsp; & emsp; ④ At the corner，Clane slot，Make sure that the wire can be pulled freely。
