I hope the contents introduced by Xiaobian can attract your attention…
The acceptance personnel will carefully inspect each hydropower node to confirm that there are no potential safety hazards or problems that may affect the service life.
5.
Protection of PVC pipe: wooden blocks shall be placed on both sides of the laid PVC pipe, or cement mortar shall be used as slope protection to prevent the PVC pipe from being trampled by workers walking back and forth during construction.
The connection between the pipeline and sanitary ware must be tight, and it can be used only if there is no leakage through the water test.
3.
Install the bottom box, which shall be fixed in the trunking with cement mortar, and the opening surface shall be horizontal with the wall; The bottom boxes installed in parallel shall have a spacing of 4-5mm; The same type of bottom box in the same room shall be in the same horizontal position and parallel to the ground.
In order to ensure the construction quality, the owner needs to have a certain understanding of the construction standards.
Whether the PVC pipeline is tightly connected: when the power line is buried in the wall, ceiling, floor or floor, it must pass through PVC pipe, and there shall be no binding kink in the pipe.
In order to ensure the safety of your family, it can not be underestimated.
4.
Xiaobian has sorted out the hydropower construction standards here.
The ground trunking shall be more than 20cm away from the foot of the wall to avoid damaging the pipeline in the later decoration.
The distance between strong and weak current trunking shall be more than 15cm to avoid signal interference and affecting the signal of mobile phone, etc.
Generally, it is not allowed to exceed 40% of the wire pipe to ensure that the wire has sufficient heat dissipation space; In the matched pipe, the number of wires should not exceed 3, so as to ensure that all wires in the pipe are live wires and will not get stuck; Single core head and multi-core cable cannot be directly connected to the joint, and the joint must be soldered.
After the water and electricity pipe slot backfilling and the water and electricity line test pass, we should fill the slot on the wall and ground, otherwise it will be difficult to see the potholes! 9.
8.
In order to avoid unnecessary troubles that may be caused by improper construction in the future.
Whether the waterproof layer is good: the waterproof requirements of kitchen, bathroom and back wall are higher than those of other rooms.
The cold and hot water pipe grooves shall be kept at a horizontal distance of 15cm to avoid energy loss; The pipeline layout shall be convenient for later installation of water heater, etc.
Pipe laying: slotted pipe laying.
After the completion of hydropower node acceptance and hydropower transformation, Gao Laozhuang will arrange acceptance personnel to conduct door-to-door acceptance.
(height of low socket: 300cm, height of high socket: 1300cm) 4.
Connect cold water and hot water with hose for pressurization test and pressurize at the same time; After installing the pressurizer, release the air and fill the circuit with water; Turn off the water meter, set the water pressure to the national standard of 0.7MPa, no leakage occurs within 30 minutes, and the pressure value drops to within 0.05Mpa, that is, there is no problem.
At the bend of the wire protection pipe, the supporting bending tool or supporting elbow shall be used, and there shall be no folds.
As the decoration owner, what should we do? How to distinguish the good and bad decoration quality of hydropower master? How to avoid problems that can’t be solved after occupancy due to the failure to control the quality of water and electricity installation in the early stage? After all, it is a time-consuming and laborious project to find problems and rework after the decoration is completed.
The above is the summary and analysis of construction standards and precautions of home decoration hydropower project.

4.
During acceptance, the owner, foreman and acceptance personnel shall be on site.
2、 What should be paid attention to in hydropower transformation? 1.
The volume of the wire in the wire pipe threading pipeline is subject to the other side.
You can compare and refer to these standards.
It should be noted that the water pipe of wire box should be grooved and laid; Pay attention to separate pipe laying for strong and weak current; At the intersection of strong and weak current, tin foil shall be used to prevent signal interference; The water pipe connection part shall be transferred by bridge bend.
2.
Specify the location and quantity of power supply and lighting required by each room, and make overall planning.
5.
Whether the water pipe is leaking: the installation layout of PP-R pipe shall be reasonable, horizontal and vertical, and pay attention that the pipeline shall not be connected to the power supply.
1、 Hydropower reconstruction construction standard 1.
Keep the slotting depth all the time without damaging the original pipeline.
7.
Water pipe welding when welding water pipes with a hot melt, pay attention to keep the water pipe joints flat and clean; After heating, the tube edge is stable, and the connector can be stuck by pushing it in at a uniform speed.
2.
5.
Slotting principle: go to the top instead of the ground, go vertical instead of horizontal; Two points and one line shall be flexibly used for line and pipe slot.
The corner of trunking shall be 135 ° to facilitate the purchase of trunking in the future.
The distance between the pipeline and the power supply shall be short, and the straight-line distance shall be 0.2cm.
Whether the ground drainage is smooth: ensure that the water collects into the natural flow on the ground and finally flows to the floor drain.
The hydropower construction of the blank new house is in the charge of the hydropower master.
Hydropower positioning, snapping and setting out before hydropower construction, draw all line directions and specific switch and socket positions on the wall with snapping lines according to the drawings, and then compare whether there are errors or places that need to be changed according to the drawings.
I believe you have also understood the importance of precautions for water and electricity decoration of new houses.
3.
The waterproof coating should be painted to 1.8m high, and other rooms should also be 0.3m high.
6.
Water and electricity installation does not seem so easy.
Slotting standard: 1.
Every prospective owner does not want his house to be dissatisfied or cause trouble after his occupancy because of the concealed works of water and electricity.
