Hydropower construction steps

1. Slotting of water pipes:  Construction method, first bounce the line and then slot. Pipeline grooves must be parallel and vertical according to requirements (if there is a hydropower construction drawing, it is better to compare the construction drawing). All pipes that must be routed in parallel are controlled at a height of 60-90 cm (from the ground), and pipes with taps must be vertical. The depth is controlled at 4 cm. After the trunking is opened, the person in charge of construction records the size and position of the slotted pipeline. It is convenient to know the position of the pipeline when the sanitary ware is installed in the future.
2. Waterway pipeline installation:   material requirements, PPR pipe, aluminum-plastic pipe. Three years ago, most users bought aluminum-plastic pipes. In the past two years, more users used PPR pipes. The pipeline is divided into cold water pipes and hot water pipes. Do not use galvanized iron pipes for hidden pipes. First of all, through construction drawings, the construction staff and the owner discuss the location and use of the water area. Arrange the water and electricity master to drain and install all the taps and water locations. If there are construction drawings, they can be arranged according to the construction drawings. If the waterway function of the construction drawing is not in place for a long time, communicate with the owner to increase the waterway function.
3. Waterway and pipeline inspection:  Waterway and pipeline inspection is very important, which is related to future waterway safety hazards. We usually do pipeline inspections by pressure testing. Pressure test is one of the methods to check the leakage of the pipeline. First, use the betting head to bet all the inner wires to death. Use a pressure gauge to test the water (12 pressures for home improvement). Check all joints of all pipes after pressing. The second method is to open the sluice for two days and nights after the gambling, and check all the connections on the third day. I generally adopt the previous method.
4. Secondary waterproofing:  After the water pipe is installed, seal all the wire slots in the bathroom with a mixture of cement and sand. After the trunk and the ground are filled with slag, clean the ground and the wall again. The wall and ground can be waterproofed when the water is dry. The wall is preferably one meter high. If there is a wall with furniture on the back of the kitchen and bathroom wall, the wall must be covered. Play the role of moisture-proof furniture. If the ground needs to be filled with slag, the slag must be filled after waterproofing. For slag filling more than 10 cm, dry mixed cement sand is used to fill slag. Do the secondary waterproof floor and wall together. (There must be a friend here who wants to ask me, the ground has already been waterproofed once when it enters the stadium, why do it again now). The waterproof surface of the ground was damaged during the water and hydropower construction, so it must be done again with the wall. The first time I entered the venue was waterproofing to make sure that the ground would not leak. After the pipes are installed, do the wall and ground again, so that the ground and wall can be more effectively waterproof.
5. Slotting of wires and lines:  After discussing the functions and requirements of electricity usage with the owner, the person in charge of construction will clarify with the electrician and make the parallel and vertical lines slotted. Put the bottom box of the switch socket. The sockets are slotted 40 cm from the ground, the wall-mounted air conditioner sockets are slotted 2.2 meters from the ground, and the switch is slotted 1.2-1.4 meters from the ground. The bottom of the switch socket should be installed with a horizontal line slot. The kitchen and bathroom must be slotted with elastic thread according to the designed use function.
6. Wire and circuit wiring:  material requirements, 2.5-6 square meters or more copper core wire, 16mm or more wire tube.
