Water and electricity installation is a key step in home renovation and it is also one of the most costly renovations. Everyone usually grants full authority to the construction party for the hydropower installation project, but he knows little about it, and there is no way to calculate the expenditure on hydropower installation. So what are the budgets for home-installed hydropower installations? The installation price of hydropower is divided into three major parts: 1. Installation of weak currents. 2. Strong power installation section. 3. Waterway reconstruction section. Next, we will introduce in detail the prices of hydropower installations and how these three parts are calculated. This will not only save costs, but will not produce waste of human and material resources.
Hydropower installation knowledge
1. Slotting of pipelines: Construction method, first playing the line, and then grooving. 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, this is related to future water safety problems. 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 waterproofing: After the installation of the water pipeline, all the trunks of the bathroom shall be sealed and mixed with cement and 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. Slotting of electric wire lines: After the construction person in charge consults with the landlord to discuss the functions and requirements of electric power, he shall make a connection with the master electrician and make a good parallel and vertical line. 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 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.
Hydropower installation notes:
Hydroelectric installation quotation includes tubing, wire rods, wiring, construction, slotting, pressure test, not including sealing slots, waterproofing, and sanitary fixture installation. Charges are calculated according to actual meter usage. The waterway reconstruction does not include special fittings and valves, and the owner of the fittings must purchase it. High-rise reinforced steel pouring structure plus 3 yuan per meter slotting fee, plus each plus 3 yuan. All hot and cold water pipes use hot water pipes. Due to the owner's inadequacy of design and manual repair of the pipes after installation, manual maintenance fees are required.
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 slottingâ€. 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.
In fact, there are many other points that need attention in the installation of water circuits in home renovations. The cost of water circuit installation is very trivial and complicated, requiring the head of the household to make a full budget for home improvement. The above is the water circuit installation budget that Xiao Bian has arranged for everyone. In the actual installation process, it needs to adapt to the situation and make corresponding adjustments according to the site construction conditions.
Note: This price is for reference only! Due to geographical differences, of course, the price will be different. For more details on the prices, please refer to the local distributors!
Editor's summary: The above is the latest water and electricity installation price budget renovation tips: how to control the hydropower reform costs related introduction, water and electricity installation is the most important steps in most of the renovation is also the most hidden, the most problematic steps, we are on the basis of the control of the budget What's more important is the quality of control. Therefore, it is advisable to carry out relevant inspection and acceptance of the hydropower installation and relevant supervision of the constructors. After the installation is completed, relevant inspections are carried out again. This not only ensures the clearness of the budget, but also ensures the maintenance of hydropower projects. quality.
