Hydropower installation is a very important part of home decoration. Therefore, before the installation of domestic water and electricity, we must have a clear construction drawing. According to the construction drawing, it is more convenient to install it after the installation or after the inspection. . Then, the following Xiaobian will introduce hydropower installation construction and water and electricity installation precautions. Hydropower installation 1, slotting the water pipe The construction method, the first line, and then slotted. Slotting of pipelines must be parallel lines and vertical lines according to requirements (better if there is a comparison of construction plans for hydropower projects). Pipes that are to be routed in parallel must be controlled at a height of 60-90 centimeters (counting from the ground). 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. 2, water pipeline installation Material requirements, PPR pipe, 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. 3, water pipeline inspection Water pipeline inspection is very important, which is related to the future water safety hidden troubles. 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. I generally take the former method. 4, secondary waterproof After the water pipeline is installed, all the trunks of the bathroom are mixed and sealed 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. (There must be a friend here to ask me, when the ground comes into play, it has been waterproof once, why do it now?). 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. 5, slotted wire The responsible person in charge of the construction consults with the owner and uses the electric power function and requirements, and then he contacts the electrician's master and plays the parallel and vertical lines. 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. 6, wire circuit wiring Material requirements, 2.5-6 square meters above copper core, 16mm above 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. Hydropower installation precautions 1, calculate the approximate amount Before estimating the amount of water before installing the water pipe, make a purchase of the material, so as not to buy more or less material, causing waste or lack of materials to affect the installation process. 2, water pipes and accessories inspection Before installation, check the water pipe and its various accessories to see if there are any problems such as damage, leakage, etc. The connection of the water pipes and fittings must be correct and secure. After the test is completed, install the pipes without any problems. 3, the direction of the water pipe It is recommended that the water pipe be safest. The main reason is that most of the waterway reforms go through dark pipes, while the water is characterized by low water flow. If the pipeline goes underground, it is difficult to find water leakage in time. Only if the water is diffused into the Jinshan or the floor is deformed and leaked downstairs, water leakage will be discovered, and it is difficult to detect leaks due to buried pipes. At this time, the huge losses are even more irreversible. They have even seriously affected friendly neighborhood relations; if the water pipes are at the top, the cost of water reform may be higher, but as a long-term investment, it is worthwhile. When the water pipe is at the top, even if it leaks, it can be discovered in time and is easy to overhaul. The loss is also small. 4, post-installation testing The boost test must be performed after installation. Pressurization tests are generally performed at 1.5 times the water pressure, and there should be no leakage during the test. 1) Close the water main valve. (ie the water switch in front of the water meter) 2) Open the faucet inside the room for 20 minutes, make sure that no water is dripped and then close all taps. 3) Close the water inlet switch of the water storage device such as the toilet tank and the washing machine. 4) Open the main valve of the water pipe. 5) Check whether the water meter is moving 20 minutes after opening the main valve, including slow walking. If there is movement, it is leaking. If you don't move around, it may be okay. (If there is a problem with the water meter or micro-permeation of the water pipe, it may be difficult to determine.) Therefore, it is recommended that a hydrostatic test be conducted after the completion of the construction. Generally, 8 kg of pressure will be applied for 20-30 minutes. (It's best to see for yourself) 5, drawing waterway map After the installation of the water pipe, the waterway diagram of the room should be drawn out to facilitate maintenance and inspection. Editor's summary: The installation and construction of hydropower and the precautions for installation of hydropower are introduced here. I hope to help everyone.
