How to calculate the cost of hydropower transformation? What are the labor and material costs?

1. What materials are needed for hydropower transformation?

Materials for hydropower transformation:

(1) List of hydropower reconstruction materials:

1. Circuit part: wires: wires, single-core wires, single-core wires, network cables, telephone lines, audio-visual wires and network connectors. Accessories: wire tube, tee, card holder, elbow spring, box-in connector lock, box-in connector lock, direct connector, waterproof insulating tape, waterproof tape, broadband network TV two-in-one TV junction box, circuit breaker and horizontal tube. Switches: single open and double control, double open and double control, single billing control, single billing control, double open and single control and three billing control sockets: socket (two eyes), socket (two eyes), air conditioning socket (16A), socket (three eyes) (10A) and single connection 500. Lamps and lanterns: kitchen lamp, kitchen work lamp, main bathroom lamp, Nanyang table lamp, north balcony lamp, living room lamp, dining room lamp, master bedroom lamp, sun sky lamp, main bathroom mirror headlight, downlight, electroluminescent transformer, bedside lamp and master bedroom bedside lamp.

2. Fuel gas: galvanized pipe, galvanized outer wire, galvanized pipe elbow, galvanized outer wire, galvanized pipe tee, galvanized pipe elbow and ball valve.

3. Waterway part: PPR water pipe, washing machine faucet, toilet basin faucet, kitchen basin, washbasin, toilet, unipolar towel rack, bipolar towel rack, towel rack, paper rack, cosmetic mirror, toilet brush, water: auxiliary material triangle valve.

(2) Detailed description of main materials:

1, wire: 2.5 square tube, generally used for lighting and ordinary sockets. 4 air conditioning lines and kitchens use square lines (because there are more appliances in the kitchen). There is also sheath line (the kind with insulation sheath outside the two wires): it is generally used when wiring on the top surface, because the top surface cannot be slotted. The wiring in the ceiling is still PVC pipe and copper core.

2.PVC pipes: There are two kinds, one is rigid pipe and the other is flexible pipe (PVC flame retardant pipe). Hoses are generally used on the ceiling, but now most decoration companies no longer use hoses because they can't pull wires back and forth. There are three kinds of PVC rigid pipes (heavy, medium and light). Cast-in-place concrete generally uses heavy pipes, because tools such as vibrators are needed, and heavy pipes can bear pressure. In terms of home decoration and wiring, ordinary light pipes can meet the requirements. Quality requirements: rigid PVC pipes should not be too soft. When you accept it, pinch it with your hand to see if it can be flattened. When the flattened pipe runs on the ground, it is easy for people to walk around to flatten the pipe. Circuit reconstruction materials: wires, conduits, screw connections, direct connections, socket springs, junction boxes, bottom boxes, electrical tapes, etc.

3. Water pipes:

(1) aluminum-plastic PP-R: Some brands are called "steady-state tubes". PP-R pipe and aluminum alloy are compounded by hot melt bonding process, which not only has the sanitary and sealing performance of PP-R, but also has the ultraviolet resistance, oxygen penetration resistance and high strength of metal pipe. Its expansion coefficient is 1/5 of that of ordinary PP-R.

(2) Ordinary pp-r: hot-melt pipe, mostly used for decoration. Economical and practical, convenient construction, hidden pipeline, long service life, etc.

Second, the price of hydropower transformation

(a) weak current includes two points:

1. Wire: used for telephone line, network cable, TV cable, audio cable, audio cable, video cable and background music.

2. Conduit: PVC hard flame-retardant electrical conduit diameter D 16 Conduit 3 weak current (telephone and TV network cable) passes through the conduit separately. Switch socket bottom box 86 is 10 yuan/piece; 1 18 type 15 yuan/piece. Add 16 information integration box and 160 yuan/set. Ensure that there is no joint in the pipe, and fill it with gypsum or cement mortar after burying the pipe. Concealed pipe price: 28 yuan/meter. Ming Guan price: 18 yuan/meter

Material: 1PVC conduit thickened cold-bent pipe wire.

For example:

First, the wall groove is patched. Take the decoration of a flat 100 as an example.

For a 100 square meter residence, the requirements for boiling water and trunking are about 65-85 meters. According to the requirements of the code, water and electricity wiring must be in the wall, but the experts who compile the code are not saints, and there will be some inconsistencies between books and reality.

In the decoration, if the wires and conduits are all from the wall, how many slots are opened in the wall according to the principle of horizontal and vertical wiring? In this case, the possibility of cracks will increase because of the different cement batches and drying time used to fill the cracks. Therefore, in the bedroom, living room and other areas, the trunking will be buried next to the keel under the floor, which avoids the possibility of too many slots cracking and saves the cost of materials such as pipes of the owner. But the kitchen and bathroom must not be wired on the ground.

The trough of the water pipe must pass through the wall and ceiling, except for one place, that is, the bathroom has a sewage pipe. Because the corner is close to the sewage pipe, it is not easy to weld the water pipe, so it is usually on the ground. I hope you will pay attention to the water pipes. Except for the special exception I mentioned above, you must go to the top of the wall. Never walk the kitchen gas pipe on the ground. If laid underground, kitchen cabinets and floor tiles will be dismantled in case of air leakage, and the losses will be very heavy.

Slotting and patching = coolie+endurance, which is inefficient. Need to be opened and sealed, divided into brick walls and cement walls. At present, it is reasonable to calculate the labor cost of slotting brick walls and concrete walls at an average price of 8- 10 yuan. Trim the slots including cement, yellow sand, glue, etc. Tools now usually include saw blades, scrapers, etc. These are all reasonable within 8 yuan.

Second, water pipes are more recognized by Pirsa and Baidie.

After years of market inspection, PPR water pipes are mostly used now, and Piersa and Butterfly are more recognized in Shanghai market. The market price is very transparent, and Pirza is the most popular choice, but I personally recommend Shanghai Baidie, which is more cost-effective, cheaper than Pirza and more guaranteed in quality. Of course, you can also use the water pipes purchased online. As a reminder, the price of water pipes and accessories basically accounts for 50% each. Some self-employed households keep the price of water pipes very low, which looks like brand-name products, but the accessories are not imported from specialized water pipe suppliers. Do you think it is a big loss?

Manufacturers or merchants calculate labor costs according to the number of kitchens, bathrooms and balconies, ranging from 150-300 yuan/set. If the kitchen is usually 1 and the bathroom is 1, it takes about 60-70 meters of water pipes. Of course, the distance between the kitchen and the bathroom and whether there are drainage pipes on the balcony will affect the number of water pipes.

Third, the gas pipeline

The pipeline from the gas meter to the cooker and shower is generally within12m. This part is generally managed by Yinhe brand 6 of the labor factory. Because it is a factory run by the reform-through-labour bureau, the quality is up to standard. The safety of gas pipeline laying involves safety issues, and personal suggestions can be laid by gas companies. This part of the cost mainly includes pipes and bends, and the labor will not exceed 10 yuan/meter.

Four, the labor cost of switch socket shall not exceed 1.5 yuan/only.

According to the owner's demand, there are about 55-65 outlets in 100 square meter. It is recommended to install sockets with switches in air conditioners and kitchens, so that many electrical appliances do not need to be plugged back and forth when used. This part of the labor cost is 3 yuan/set, and there are also expenses such as cassette, octagonal box and hose. The medium quality cassette is about 1.6, and the labor cost does not exceed 1.5 yuan/set. We also need some electric dressings.

Verb (abbreviation of verb) PVC sleeve of electric wire in conduit.

Usually, PVC bushing (4-minute and 6-minute charging) of Zhejiang Caizhong Line is used, and the quality is better. Pipes commonly used in home decoration are divided into light and medium-sized ones, which mainly involve the thickness of the pipe wall. Personally, I think the light type is enough. There is no need to use the medium size. The price of the medium size is a few hairs higher than that of the light type. The quantity is related to the wiring direction and quantity. Strong current and weak current must be worn separately, generally within 200 meters.

Six, strong wires and weak wires

The electric meter capacity of general residence is 5(20)A or10 (40) A. Generally, users in single-phase power supply should have three incoming wires (phase wire, neutral wire and protective grounding wire) in the incoming distribution box, and the main incoming wire switch must be able to cut off the phase wire and neutral wire at the same time. According to the room structure and actual use needs, sockets can be divided into lighting, sockets and air conditioning circuits.

Seven, TV distributors had better be around 80 yuan.

Due to historical reasons, monopoly industries have led to the installation of only one TV per household. If two TVs are installed, cable TV fees will be charged all the way. As a result of this monopoly, many houses currently have only one regular TV line. If several TVs are connected in series on a line, the TV signal will be attenuated, and it is necessary to amplify the signal with a TV distributor. This kind of distributor can be divided into "secondary distribution" and "tertiary distribution" according to the form of one inlet and several outlets. The price difference of electronic components inside is very large, and the store can't reach 10 yuan, but don't buy this kind. Generally, the price that meets the eligibility criteria is above 30 yuan, preferably around 80 yuan. After the installation of qualified products, the TV signal index data can reach more than 75bd.

Eight, wall hole

Due to the need of indoor pipe piercing, each household should make 5-20 holes in the wall. Market price 15-25 yuan/Taiwan, but some residential properties are designated as hole diggers, and the charge is 45 yuan/Taiwan. Because the number and price of holes can't be determined before the construction starts, the construction workers can help contact the digger, which is affordable.
