Jinan Home Decoration Company teaches you the basic knowledge of hydropower plant
1. Water pipe grooving
Construction method. First spring line and then slot. Pipeline grooving must be parallel or vertical as required, which is better than the comparative construction drawings with hydropower construction drawings. Parallel pipelines are required to be controlled in the center of 60-90 cm high, and pipes with taps must be vertical. The depth is controlled about four centimeters. After the groove is cut, the construction personnel must remember the size and position of the grooved pipeline. It is convenient to determine the detailed position of the pipeline when the pre-cleaning device is installed.
2. Pipeline installation
Decoration information requirements. PPR pipe. Aluminum plastic pipe. Three years ago, many people liked to use aluminium-plastic tubes. In the past two years, PPR tubes have been used more than others. There are two kinds of pipes: cold water pipes and hot water pipes. The hidden pipes can not be used with galvanized iron pipes.
If the function of dry road is unreasonable, we must communicate with the owners and add the function of dry road.
3. Pipeline Reflection
Reflection on dry road pipeline is very important, which affects the current achievements of hidden dangers of dry road safety. Pressure testing is often used to reflect on whether the pipeline can leak. Pressure test is one of the ways of reflection. First, all the wires are blocked by a plug, and then the water test is pressed by a pressure gauge. After the pressure, reflect on all the pipelines and joint status whether there is leakage. Another way is to open the valve for two days and two nights after the plug is blocked. On the third day, come to reflect on the status of all the joints to check whether there is leakage.
4. Secondary waterproofing
After the dry road pipeline installation, mix cement mortar to seal all the troughs in the bathroom. When the groove and the air are dry, clean the air and the wall again. After the water on the wall is dry, it can be waterproof. The waterproof on the wall should be as high as one meter. If there is furniture or household appliances on the opposite side of the toilet, it must be made full of walls. In case of damp furniture, the air needs to be filled with slag after waterproofing. Slag more than ten centimeters is paved with cement mortar. Do secondary waterproof air and wall should be done together.
5. Cable slotting
After consulting with the owner to make good use of the power and requirements, the builders of Jinan Decoration Company and the electrician apprentices come to the bottom and play the parallel and vertical slots. After installing the switch socket, the socket should be slotted 40 centimeters away from the air, the wall-mounted air conditioning socket should be slotted 2.2 meters apart from the air, and the switch should be slotted 1.2-1.4 meters apart from the air. Switch socket fittings should be grooved by elastic degree lines. The bathroom needs are combined with the use of power to stop the slotting of elastic wires.
6. Wire and circuit wiring
Data selection requirements. 2.5-6 square meters of copper core wire. 16 mm above the line tube. Wiring Requirements: Most of the electrical apprentices do not think about strong and weak electricity. Switches. Air conditioning sockets and electrical sockets need to be separated. Therefore, slotting can also save a small amount of costs. The wiring requirements of strong and weak electricity should be 30 cm apart, air-conditioning public sockets should be grouped into groups of more than 6 square wires, electrical public sockets should be 4 square wires and switches should be grouped into groups of 2.5 square wires. The air conditioning line is 2 meters apart in the air. Electrical wires are wired in the air, switches, and fragmented sets of lighting are wired on walls or roofs. Switch sockets must be vertical or horizontal when they are installed, so that the front panel device is more flat. The kitchen switch and socket must be combined with the cabinet function to stop the comprehensive arrangement and device. Therefore, after the wires are laid out, the construction workers record the layout and layout dimensions of the wires, so as to facilitate the installation of various decorations and furniture in the early stage.
