How to carry out water and electricity slotting in family decoration
1. Water pipe direction confirmation and water equipment positioning:
Customers determine the direction of water pipes according to the decoration design drawings and room structure. The direction of water pipes can be divided into suspended ceiling layout, wall slot layout, ground layout and exposed pipe installation. Choose the way to negotiate with the decoration.
Generally speaking, the principle of slotted water pipes is "take the roof instead of the ground, vertical instead of horizontal", because there are many buried wires underground.
If the original underground pipeline is destroyed, it will be very troublesome, and if you walk on the ground, in the later transformation process, if the electric drill destroys the water pipe, it will affect safety. It is not easy to find the water on the ground, because the water flows downwards, and the leaking place does not necessarily flow out first. Only when the water leaks downstairs or when the water overflows Jinshan will the water be found, but because it is a concealed pipe, the leaking place cannot be found immediately, so the loss will be considerable; If you go above, the kitchen and bathroom can be hung with aluminum gusset plates. When we go through the wall and the entrance, we can walk along the corner and wrap it with plaster thread without affecting the appearance.
The water pipe leads from the top to the bathroom. When water is needed, open the vertical slot and reserve water outlets such as shower, basin and washing machine at a suitable height. The advantage of this is that you can judge the direction of the water pipe according to the position of the water outlet when you finish decorating and tiling.
All water pipes are vertically upward at the water outlet, so as to avoid water pipes from being damaged for any reason, and it is easy to maintain once water leaks. 2. Waterway design should pay attention to:
1) Waterway design should first consider all water-related equipment, such as water purifier, water heater, kitchen treasure, toilet, washbasin, their locations, installation methods and whether hot water is needed.
2) Try to use gas or electric water heaters in advance, so as to avoid changing the type of water heaters temporarily, which will lead to repeated reconstruction of waterways.
3) Except the water outlet of washbasin, toilet, washing machine, etc. It is best to take them out one by one, so that it is convenient to mop the floor after receiving water; It depends on the owner's preference.
4) After the location of the washing machine is determined, the drainage pipe of the washing machine can be considered in the wall, which is beautiful and convenient.

3. Slotting process specification:
1) After communicating with the construction personnel, start the construction from water improvement. Draw a line with ink lines first, and outline the route that needs to be taken (it can be seen from the route map that it is horizontal and vertical. If there are different opinions or changes at this time, you can also discuss with the master). These preliminary preparations will take about an hour.
2) After the thread is finished, it is to open a dark groove, cut the grooved surface by wire cutting with a special tool cutter, and then cut the groove with an electric hammer. In addition, it should be reminded that,
There are many and thick steel bars in the load-bearing walls of some communities, so it is impossible to cut the steel bars (affecting the quality of houses), so we can only make them shallow (thickening cement is needed when sticking bricks) or take exposed pipes or bypass other walls. 4. Slotting construction size requirements:
Be sure to leave space between hot and cold water pipes. Because hot water is heated by a water heater, heat is also lost in the recovery process. If the hot and cold water pipes are close together, the cold water is also circulating, and the warm loss of the hot water pipe is also very serious.
Wall hole size requirements: if the wall hole diameter of a single water pipe is 6cm, if two water pipe wall holes with a diameter of 10cm are drilled or separated by two wall holes with a diameter of 6cm.

Hydropower slotting 1 1 construction specification
1, before slotting the wall and ground, use ink box to make elastic line positioning. The pipeline groove buried in the wall should be horizontal, firm and straight, and bending is not allowed. Under special circumstances, it must be approved by the supervisor, the notch on the wall should be kept > 33mm, and the surface and wall of the pipe should leave about 15mm powder ash layer to prevent the wall from cracking.
2. Without permission, public electrical facilities such as lightning protection grounding wire and protective grounding shall not be destroyed or changed.
3. When the power line pipe is buried, the distance between the power line pipe and the weak current pipe should be more than 500mm, and the parallel distance between the power line pipe and the hot water pipe and the gas pipe should be not less than 300mm.
Reduce the rotation as much as possible, avoid the installation position of wall mirrors, shelves, furniture and other things, and prevent the damage of electric hammers and nails.
5. Unless otherwise specified, in the same suite, the switch is about 1200- 1500mm from the ground, the door is about 150-200mm, and the socket is about 300mm from the ground. The socket switches are on the same horizontal plane, and the height difference is less than 8 mm When installed side by side, the height difference is less than1mm.
6, all kinds of strong and weak electricity socket interface should not be lacking, both sides of the bed should be equipped with power sockets and a telephone socket, near the computer desk, living room TV cabinet background wall should be equipped with more than three power sockets, and set up the corresponding TV, telephone, multimedia, broadband network and other sockets.
7. Audio, television, telephone, multimedia, broadband network and other weak current lines are laid in the same way and requirements as power lines, and their sockets or boxes are installed side by side with power sockets, but a set of tubes is not allowed for strong and weak current lines.
8. All wires entering the wall shall be buried with PVC flame retardant pipes above 16, and the wires account for the pipe diameter.
9. When using the original conduit, the power supply conduit should make a reasonable turning radius when crossing the ground. Pay special attention to the tight connection of underground casing, and joints are not allowed underground. Before the ground is closed, the PVC pipe sleeve must be protected, and there must be no rupture damage; When laying floor tiles, PVC sleeves should be completely covered with cement mortar.
10, the wires and lamp cap wires in the ceiling should be protected by PVC metal bellows, and other materials are not allowed to replace them. When it is difficult to slot the ceiling, the wire can be directly buried after passing through the wax-like pipe, but the wire box must be kept for wire replacement. The expansion pipeline laid in the ceiling should be fixed with pipe clamp, and the distance from the ceiling surface should be greater than 50 mm
