Anonymous users2024-02-09In modern people's lives, water and electricity are basic projects, if the work of water and electricity is not done well, it is easy to cause a lot of trouble, but what is the installation skills of water conservancy and hydropower? When completing the installation of hydropower, if there is no focus, it will cause a lot of trouble, and what is the focus of hydropower installation?
1. Water conservancy and hydropower installation skills.
1. Before the installation and construction of water conservancy and hydropower, there must be electrical (strong current, weak electricity), water supply and drainage design and construction drawings.
2. The water conservancy and hydropower installation pipe should be selected of a certain size (thickness), not only to make the wire penetrate, but also to leave enough space to make the heat generated by the wire through a large current can be dissipated. Generally, the ratio of the cross-sectional area of the wire to the cross-sectional area of the threading pipe is 1 3 1. It is strictly forbidden to plug the wire to the threading pipe.
3. Lines with different voltages, different circuits, and different signals are strictly forbidden to wear in the same conduit. It is strictly forbidden to lay the wires directly in the wall, in the floor, under the floor or on the ceiling without any protection.
Second, the focus of hydropower installation.
1. Slotting of water pipelines for hydropower installation: construction method, first elastic line, and then slotting. The pipeline slotting must be parallel lines and vertical lines as required (if there are hydropower construction drawings, it is better to compare construction drawings).
The pipes of the horizontal walking line must be controlled at a height of 60-90 cm (from the ground), and the pipes with faucets must be vertical. The depth is controlled at 4 cm. After the trunking is opened, the construction person in charge should remember the size and location of the slotted pipeline to provide a line for future sanitary ware installation.
2. Waterway pipeline installation: aluminum-plastic pipe, PPR pipe. Three years ago, most users bought aluminum-plastic pipes, and in the past two years, there have been more users of PPR pipes.
The pipes are divided into cold water pipes and hot water pipes. Hidden pipes do not use galvanized iron pipes. First of all, through the construction drawings of hydropower installation, the construction personnel discuss the location and use function of the water area with the owner.
Arrange for the plumber 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 has been lacking for a long time, communicate with the owner to increase the waterway use function.
3. Wire and circuit wiring: material requirements, copper core wire above square meters, and wire pipe above 16mm. Cabling Requirements:
Most electricians do not consider the strong and weak currents, switches, air conditioning sockets and electrical sockets separately in the circuit wiring. Slotting also saves a lot of work.
Water conservancy and hydropower installation skills are as above, generally only professional plumber masters can know the relevant skills, even if ordinary people do not understand the skills, it doesn't matter. There are also many key points of hydropower installation, in order to ensure the focus of the final installation, it is best to be able to do a good job of design and determine the final effect before the installation work.

Anonymous users2024-02-081. Housing renovation, first of all, according to the design drawings of the house to carry out part of the transformation, such as the smashing of some walls, the modification of some parts.
2. Pipeline slotting, pipeline slotting includes two parts, one is water pipe slotting, and the other is telecommunication line slotting. The owner is better to see the construction quality in person during the construction, generally before the slotting must play the horizontal and vertical lines, in accordance with the line for construction, in the construction must see whether in accordance with the hydropower diagram slotting, if there are changes, be sure to indicate.
3. Water pipeline installation, water pipe materials are generally PPR pipes, aluminum-plastic pipes, especially PPR pipes, in this piece, mainly pay attention to the placement of faucets, this piece of household owners must personally supervise and observe, so as to ensure that the functional practicability is met.
4. Wire wiring: Now the more common wires on the market have more than square meters of copper core wire, here special attention should be paid to the strong and weak electricity, switches, air conditioning sockets and electrical sockets separately wiring, and pay attention to the switch socket bottom installation must be horizontal and vertical, so that the back panel installation will be smoother.
5. Water pipe inspection:
After the construction is completed, the water pipe inspection is essential so that the potential safety hazards of the waterway can be ruled out. The usual test method is pressure test, which is to bet all mouths to death with the gambling head first. Test the water with a pressure gauge. After compression, inspect all pipes and joints.
6. Waterproof. After the pipeline installation is completed, the trunking of all wet areas can be sealed with cement and sand, and it is necessary to make half walls and full walls.
The better water conservancy universities in China include Hohai University, North China University of Water Resources and Hydropower, Nanchang Institute of Technology, Yellow River Water Conservancy Vocational and Technical College, etc.
I'll probably tell you about some of the school's better professional rankings. (based on employment rate and salary). >>>More
According to the current division of majors, architecture, civil engineering, and water conservancy and hydropower engineering (that is, water conservancy and hydropower construction) are three majors, each of which is independent. If you want to talk about the relationship between them, it can be said that they are all civil engineering. >>>More
I am a student of the school as far as I know, the old area is more than 200 acres, the new area is more than 1,600 acres, the new students should live in the new district, the restaurant in the new district is OK, if you want to eat well, it is a bit expensive, 300 yuan for a month to eat, the new area is more desolate in the past few years, it is said that it is more prosperous now, there are Internet cafes outside the school, restaurants, and relatively inferior stores. . . There are also many interesting things, and there are Henan College of Traditional Chinese Medicine, Zhengzhou Aviation Institute and other colleges and universities near the new area. Finally, let's talk about the construction of the new district, now it is estimated that half of it has been built, there are more than a dozen dormitory buildings, five teaching buildings, temporary libraries, restaurants, and several laboratory buildings of various departments, and the faculty and staff accommodation building has just been completed and put into use, but there are still comprehensive administrative buildings and libraries that have not been built, and are being built one after another.
This sort is not necessarily fair, I am from Sichuan University, and I think Sichuan University is still relatively easy to test. Because there are many people recruited, there are relatively few people who take the exam. I also considered Dalian Institute of Technology back then, and the score line of Dalian Institute of Technology was as much as 30 points higher than that of Sichuan University, so it can be imagined. >>>More
