Hydro installation costs Hydro installations pay attention to quality issues

When you buy a house, you need to decorate it. Since the decoration will install water and electricity. What is the price of water and electricity installation ? This is the question most often asked and asked by the head of a household. There is no doubt that the decoration budget is the most concerned issue for every head of household and the basis for the decoration of the head of the household. The installation price of water and electricity is divided into three parts: 1. Installation of weak electricity section. 2. Strong power installation section. 3. Waterway reconstruction section. Next, I will give you a detailed introduction on how to calculate the prices of these three parts of the hydropower installation price.

Hydropower installation specification

1. Water installation specification: Water installation is divided into two types: water supply installation and drainage installation. In many modern homes, the general water pipes are installed in the wall. On the one hand, the principle of the water supply system is to ensure water quality, water volume, and water pressure; on the other hand, the task of the water supply pipeline is to ensure the safety and convenience of water supply. Of course, At the same time, it is also convenient for construction, maintenance and aesthetics.

2. Electrical installation specification: With the increase of home appliances, modern people have more and more demand for electricity. Therefore, in the electrical wiring project, it must be carefully engineered by a professional electrical engineer before it can be constructed. Such owners It is convenient and safe when using electricity.

Hydropower installation specification content

The principle of wiring: horizontal and vertical. The use of special financial PVC flame-retardant wire tube, wire tube must be fixed in the online slot, wire box and line pipe should be used when the lock mother, straight tube every 80 cm using a tube card, a corner every 20 cm use a Tube card.

Electrician's socket principle: the socket is in the upper part of the wall, and is vertically slotted upwards in the wall, and is installed in the installation line of the decorative angle line at the top of the wall. If it is in the lower part of the wall, it is vertically slotted downwards to the bottom of the mounting skirting board. The groove depth should be the same, the groove line and top straight should first eject the control line on the wall surface, and then use a cutting machine to cut the wall surface and slot the machine.

PVC pipe construction principle: use Zhongcai PVC pipe, use spring bending at the elbow, do not use 90-degree elbow and three-way (at this point we basically do not have this kind of situation), the line must be installed when installing The cable bushing is connected by glue. The edge of the bushing should be tight, straight and flat. The corner should be cut at the right angle corner. After the arc-shaped interface is cut on one side of the incision, it is bent and installed.

  

Hydropower installation price

First, the hydropower installation price budget - to discuss a good slot and no slot price

In the installation of water circuit at home, the price of slotting and not grooving is not the same. Slotting is to open a slot where there is no slot and put a line or pipe into it. Instead of grooving, the wires and pipes are directly installed on the outside of the wall, and then insulated by insulating objects, the amount of work for grooving is relatively large. Of course, some companies will subdivide the slotted price into two kinds of prices: “non-load-bearing wall slotting and bearing wall slotting”. Therefore, it is necessary to determine the installation method before laying the lines and pipes, so as to discuss the separate prices.

Second, the hydropower installation price budget - weak installation materials and installation prices

Weak electrical installation materials include wires and conduits. The line includes wire rods for various household appliances such as telephone lines, cable TV lines, and broadband lines. The line pipe is a PVC flame-retardant electrical pipe, D16 diameter pipe 3 weak electricity (telephone, television network cable), separate wear pipe; general switch socket installation bottom box 86 type price 10 yuan each, 118 type 15 yuan each One, add 16 information integrated boxes plus 160 yuan each. In addition, in the hydropower installation process, it is necessary to ensure that there is no joint in the pipe. Dark pipe price is 28 yuan per meter, Ming Guan 18 yuan per meter. Also needed are: 1 PVC pipe, thick cold bends, wires, etc.

Third, the hydropower installation price budget - strong installation materials and prices

During the installation of strong electrical power, among the required materials, no more than three fire-retardant electrical conduits are to be threaded, otherwise once the number of three exceeds three, an increase of five yuan per meter is required. At the same time, there is no connector in the pipe, and the junction box is used at the branch line. The switch socket bottom box is similar to the weak point installation material, but more than 4 square meters of wire plus 10 yuan per meter, the excess part will also be added to the home improvement budget. In addition, if there are multiple pipes with the same slot, the construction team will charge according to the number of dark lines. Among them, the dark pipe is generally priced at 35 yuan per meter, Mingguan 25 yuan per meter. Material is thickened with cold PVC pipe, wire and so on.

Fourth, hydropower installation price budget - waterway reform

The waterway reconstruction is also a “concentrated” effort in the installation of hydropower. The head of household must pay special attention. Among them, the waterway reconstruction data are: concealed 20PP-R water pipe is 60 yuan per meter, surface mounted 20PP-R water pipe 45 yuan per meter. In addition, the launch price for 50 PVC pipes is 60 yuan per meter. It should be noted that the pipeline is a Weixing or Kinder pipe, and the water is a plastic pipe.

In addition, there are other points to pay attention to the installation price of water and electricity. For example, each meter needs to include one equal-diameter and different-diameter pipe sleeves, plus a 90-degree elbow. Valve hardware is not provided during construction. In addition, 25 water pipes plus 10 yuan per meter, less than one meter by one meter. In addition, the cost of punching by workers during construction is calculated separately. Generally, the calculation is based on whether the wall is loaded or not. The load-bearing wall is 40 yuan and the non-bearing wall is 20 yuan.

Note: This price is for reference only! Due to geographical differences, of course, the price will be different. If you want to know more about the relevant price details, please use the local dealers to provide!

Problems with the installation budget

Copper core cable head: copper core cable head is determined according to the production process, which can be divided into dry type and cast heat shrinkable type. However, sometimes the cable head is only used for simple crimping. At this time, it is not possible to apply cable heads but to press copper terminals.

Toilet type stool quota: Each local quota has its own characteristics. First of all, we must understand the composition of its fixed subheads to see the composition and consumption of material feeders.

Control cable rating: The control cable is usually measured every 100m according to the number of cores of the cable. The power cable is the difference between the effective cross-sectional area of ​​the cable measured in 100m. Although the quota is the same as its job content, the difference in base price is relatively large.

Drainage pipe fittings quota: In the subheadings of the rating, checkpoints cannot be applied to sub-purposes. The traps need to be divided into sub-purposes. There are fixed sub-purposes, and the submerged buckets must be borrowed from the civil construction quota.

Calculate the air duct: The air duct is calculated according to the different specifications of the map by the unfolded area, and the length of the air duct is the length of the center line of the legend.

  

Quality problems for hydropower installations

1. There is a gap between the panel of the switch and the socket and the surface of the building, which is not even.

Solution: Adjust the screws behind the panel and tighten so that it fits snugly against the building's surface.

2, the phase of the socket, the zero line and the ground line crimped between very chaotic, its switch is not broken phase.

Solution: It is corrected according to certain installation specifications.

3, multi-light room switch and control lamp sequence does not correspond

Solution: When wiring, attention should be paid to distinguishing the conductors of the lamps and pressing them in order to ensure the consistency of their switching directions.

4, when installing its wire panel, its a word screw and Phillips screw, is not uniform.

Solution: For the aesthetics of the entire space, a uniform screw should be used when fixing the panel.

5. When the switch and socket are installed in the same room, the height will be within the allowable deviation range.

Solution: Correct it immediately.

6, the switch, socket box pan head wiring confusion.

Solution: In the installation, you can change it to the chicken head connected to the wire head, and then branch the wire to a switch or socket head; you can also use the LC safety crimping cap after crimping the total head, then branch wire connection .

Editor's summary: There are too many stringent regulatory requirements for the installation of hydropower in hidden projects. It is also an indispensable part of the renovation project. It is also a very important part of the project. Therefore, everyone must strictly comply with the rules and regulations during the renovation. In order to avoid unnecessary injuries and economic losses.
