Is it better to slot or not slot the ground in hydropower reconstruction? Listen to the master!

Hydropower transformation is a very important step in decoration. In the renovation process of hydropower transformation, many owners are entangled in whether the ground is slotted. Next, I will discuss whether it is better to slot or not to slot the ground in hydropower reconstruction. There are different opinions on whether to slot the water and electricity installation, which is nothing more than beautiful slotting, no loss of floor height, long service life of the pipeline and so on. However, slotting may destroy the feel structure of the floor, or the tiles will be empty after laying. Therefore, many owners of new house decoration are always entangled in the installation of water charges. We might as well listen to the decoration master and talk about his experience.

First, do you need a trough for hydropower transformation?

(A) the benefits of water and electricity decoration slotting

1. The main purpose of water and electricity slotting is to protect the pipeline. If there is no slot, the pipeline will be exposed on the ground during the construction process, and workers will inevitably encounter it when walking back and forth. If it is not good, it will damage the line.

2. The height of water and electricity slotting ground will not be too high. If there is no trough, in order to conceal the hydropower pipeline, the ground should be raised again. Doing so occupies the height of the house.

3. In the slot, the line is fixed and will not move back and forth, which is safer and more assured.

(B) Shortcomings of slotting in water and electricity decoration

1, destroying the building structure. If there is no protective layer on the ground, slotting will undoubtedly destroy the structure of the wall. The ground without protective layer can't be slotted.

2, water and electricity slotting is more than no slotting, because slotting and joint filling takes time, which prolongs the construction period.

Generally speaking, slotting is much better than not slotting. In the long run, although the cost of slotting is much higher, if the water pipe is exposed on the ground without slotting, it will be very unsightly, and it will be easily damaged and trampled for a long time, which will increase the possibility of bursting. So we can see that slotting can be done once and for all, avoiding future renovation and reconstruction. If it is cheap and not slotted, the construction quantity will increase in the future. It is better to choose slotting, which is troublesome once and convenient a hundred times.

Second, the basic process of hydropower transformation

Steps: The design of water and electricity direction is based on the design drawing of the living room and the specific needs of customers: the owner, designer, water and electricity master, floor heating master and central air conditioning installation master need to go to the site together when positioning. Generally speaking, all lines and pipelines should be horizontal and vertical, so that after taking photos and archiving, it is easy to find the specific position and direction of each line and pipeline, which is convenient for future maintenance and installation. If there is a problem in the follow-up, don't start all over again. The right medicine? Do it.

Step 2: The workers make slots on the wall or the ground according to the direction. In the process of slotting, the phenomenon that the wall is slotted more than 30cm horizontally is not allowed, because the transverse slotting will destroy the bearing capacity of the whole building, reduce the seismic capacity and make the wall easy to crack. If it is an insulation wall, opening a long horizontal groove may cause the insulation layer on the upper part of the groove to fall off as a whole. Generally, the slot on the wall should be vertical and vertical.

Step 3: Bury pipelines (including wiring and connecting pipelines) and cassettes. During circuit construction, the pipeline should be installed first, and then the conductor should be threaded, so as to avoid the phenomenon that the conductor can't twitch when changing the line in the future. Hoses should not be used for threading pipes to prevent dead ends. At the same time, the circuit connector should not be exposed, but should be installed in the junction box, and no connector is allowed between junction boxes.

Step 4: Test the circuit, and carry out pressure test on the waterway. After acceptance, attention should be paid to the preservation of circuit construction drawings, which should be consistent with the actual situation, and the specifications of wires, switches and sockets should be marked on the drawings. Drawings are a reference for future maintenance, and many owners will ignore them. If conditions permit, it is suggested that after the completion of water and electricity, photos of various parts should be taken with a camera.

Step 5: Smooth the trunking with cement mortar.

Step 6: After the wall painting or wallpaper paving is completed, install the electric sidewalk board.

3. What should I pay attention to when slotting water and electricity?

1, weak current laying should follow the principle of one pipe and one line. Generally, household conduits are 16 pipes or 20 pipes. The depth of water and electricity slotting is not less than 3cm for the embedded pipe wall with a diameter of 1.6cm, so that the sealed wall surface will not be uneven and the wall paint will be prevented from cracking due to long-term shallow sealing.

2. Generally speaking, the distance between strong and weak conduits is about 15cm. In order to avoid signal interference, it is necessary to wrap tin foil paper at the intersection of strong and weak current, which generally exceeds the intersection 15cm.

3. The transverse slotting of load-bearing wall should not exceed 100cm: transverse slotting will destroy the load-bearing capacity of the whole building, reduce the seismic capacity and make the wall surface easy to crack. Generally, the groove on the wall should be vertical and vertical.

4. The distance between trunking and trunking should not be less than 100mm, and the number of wires and tubes in the same trunking is not recommended to exceed 6.

5. Meet the catheter 90? When bending; The slot position should be increased; So that the catheter can present two 45? Bend to facilitate threading during construction and future maintenance.

6. Displacement position of ceiling chandelier: Pay attention to the position of reinforcement when slotting on the top surface of the floor, and the slotting depth is about 10mm, which is convenient for wiring with tape after wearing yellow wax pipe. Bare wires are strictly prohibited.

7. Due to the improvement of water pipe quality, the former galvanized pipe has been replaced by PVC water pipe, which will not produce condensed water at low temperature, so the cold water pipe does not need heat preservation. Of course, if you feel more at ease, you can choose to do heat preservation.

Presumably the troubled car owners have solved their inner problems. In short, whether the ground needs to be slotted follows these three rules: if the budget is enough, the slotting money can be saved; Slotting is also limited to the decorative layer, so it is not necessary to hurt the muscles and bones and destroy the building structure; Waterway reconstruction must be on the roof, and the circuit is fine.
