Hydropower must be built with safety in the design and construction process. Standards, as far as possible, must be practical, careful, and save the principle. We also know that hydropower construction is a concealed project. A concealed project is a project that is rarely moved or modified in the future. Hydropower construction also determines the importance of material selection and construction. Whether it is a wire or water pipe selection, we must uphold quality first. Principles, the greatest degree of protection of future life safety factors, the following we will give you a brief introduction to the commercial housing installation knowledge of hydropower and hydropower installation precautions.
| I. Commercial Housing Hydropower Installation: |
1. Slotting of electrical wiring: The responsible person in charge of the construction consults with the owner and uses electrical functions and requirements. He then contacts the master electrician and makes the parallel and vertical slots. Place the switch socket box. The socket type is slotted 40 cm from the ground, the hanging air conditioning socket is slotted 2.2 meters from the ground, and the switch is slotted from the ground 1.2-1.4 meters. The bottom of the switch socket is installed and the horizontal line is to be slotted. The kitchen and bathroom rooms must be slotted according to the designed function.
2. Slotting of pipelines: construction methods, first playing the line, and then grooving. Pipeline slots must be parallel and vertical as required. Pipes that must be routed in parallel must be controlled at a height of 60-90 cm. Pipes with faucets must be vertical. Depth control is 4 cm. After the slot is opened, the person in charge of the construction shall remember the size and position of the slotted pipeline. It is convenient to know the position of the pipe when installing the sanitaryware.
3. Water pipeline inspection: Water pipeline inspection is of vital importance. This is related to the future water safety hazards. We usually use pressure testing to do pipeline inspections. Pressure test is one of the ways to check leaks in pipelines. First, all the inner wires are staked to death with a gambling head. Use a pressure gauge to suppress (12 pressures for home decoration) test water. Check all pipe fittings after pressure. The second method is to open the floodgates for two days and two nights, and check all joints on the third day.
4, water pipeline installation : Material requirements, PPR pipes, aluminum plastic pipe. Most users bought plastic tubes three years ago, and more users use PPR tubes in the past two years. The pipeline is divided into cold water pipes and hot water pipes. Hidden pipes eliminate the use of galvanized iron pipes. First of all, through the construction plan construction personnel and the owner to discuss the location and use of water functions. Arrange the water master to drain and install all taps and water positions. If there is a construction drawing, it can be arranged according to the construction drawing. If the waterway function of the construction drawing is not in place for a long time, communicate with the owner to increase the waterway use function.
5. Secondary waterproofing: After the water pipeline is installed, all the trunks of the bathroom shall be sealed and mixed with cement sand. After the trunking and the ground are dry, clean the floor and the wall again. The water on the wall surface can be used for waterproofing. It is best to make the wall waterproof one meter high. If there is a furniture wall on the back of the kitchen wall, it must be full of walls. Plays a damp-proof role for furniture. If the ground must be filled with slag, it must be filled with water after filling. Fill the slag more than 10 cm with cement sand dry mix slag. Do the secondary waterproof floor and the wall together. The ground surface has been damaged when the water is used in construction of water and electricity, so it must be done together with the wall. The first time to enter the venue to do waterproofing is to be able to determine that the ground will not leak. After the pipeline is installed, the wall and floor will be re-doed once again to make the floor and wall more effective in waterproof protection.
6, wire circuit wiring: material requirements, 2.5-6 square meters above the copper wire, 16mm above the line tube. Wiring requirements: Most electrician masters did not consider the separation of strong and weak currents, switches, air conditioning sockets, and electrical outlets in the circuit wiring. So slotting also saves a lot of processes. The requirements for strong and weak power cables are 30 cm apart at the bottom of the limit, and the air-conditioning sockets are dedicated to groups of wires of more than 6 square meters, electrical sockets are dedicated to 4 square meters, and switches are grouped with more than 2.5 square meters. The air conditioning line group is more than 2 meters away from the ground. The ground wire of the electric wire group, the switch and the top line of the wall of the lamp line group. The bottom of the switch socket must be installed horizontally and vertically so that the rear panel installation will be evener. The switch sockets of the kitchen shall be arranged and installed according to the use function of the kitchen cabinet design. After all the electric lines are laid out, the person in charge of construction remembers the arrangement and discharge dimensions of the lines, which is convenient for the installation of various home accessories in the later period.
| Second, water and electricity renovation acceptance note: |
1, the test pressure should be 1.5 times the working pressure of the pipeline system, and shall not be less than 0.6MPa, the pressure value is generally between 0.6MPa-0.8MPa, not the bigger the better, the longer the pressure is not better.
2. The pipelines buried in the floor surface and in the wall must be hydrostatically tested before sealing the tank.
3. When testing pressure, the pipeline shall be fixed, the joints of the pipeline shall be exposed, and the water outlets of the pipeline shall not be connected with the water distribution equipment.
4. Pipes connected by hot melt shall be tested after the installation of the pipeline for 24 hours.
5, other reasons for testing the difference grid: plug is not installed, the main valve of the valve type has quality problems.
Summary: After reading so many notices about water and electricity decoration, what do you think? Does it feel like you have learned a lot of knowledge? In fact, decoration is a big project, and major projects will contain more details and precautions. Minimize the incidence of failures and make home life more comfortable and warm. The complete knowledge of water and electricity installation of the commercial house and the installation considerations for hydropower are introduced. I hope I can help you.
