The correct procedure for acceptance of hydropower
First, look first at the water pipeline. Water pipelines should meet the following requirements:
1. The pipelines are arranged in a rational and well-laid manner; switches and valves are installed smoothly.
2. Water pipes and accessories are tightly connected.
3, to ensure that the drainage pipeline is free, no obstruction, no leakage.
Second, look at integrated wiring. Check from four aspects:
1. All electric wires and conduits must be national standard products. The general power cords are divided into hard wires, cords, and sheathed wires. For ease of maintenance, the power cords should be sleeved.
2. The electrical wiring should be laid with a dark pipe. There should be no joints and kinks in the pipe. No twisting is allowed. It is forbidden to bury the wire directly in the plaster layer.
3, the pipe and wire are firmly installed, straight and smooth, tightly packed, and there is no joint in the pipe.
4, in line with the "phase line into the switch, zero line into the lamp" provisions, three-hole socket grounding wire should be laid separately, not mixed with the work of the zero line.
The third look at the water treatment.
1. All waterproof materials must comply with the requirements of environmental protection standards and related standards, and the products should have factory-qualified certificates.
2, brushing the surface of the waterproof layer of the grass-roots level, small uneven, loose, empty drums, sand, cracking and other defects, the moisture content should be less than 9%. Floor draining kitchen and all toilet floor waterproofing layer around the wall and should be turned up, a lot of 250mm above the ground, not pour water, water, 24-hour closed water test no leakage.
3, waterproof layer should be firmly bonded, no slip, edge, blisters, wrinkles and other defects; floor drains, pits, drains, etc. should be kept open, the construction of protective measures.
4, through the wall, floor, etc. have been firmly in good roots, should be protected during the construction process shall not damage the displacement; for all parts that are prone to voids to be finely processed to prevent leakage.
5, waterproof material must be uniform coating, no leakage coating, no damage, uneven thickness, etc., must be closed after the water pass the next process of construction.
Water and electricity acceptance considerations
1. Concealed water supply pipelines should be inspected for water. Newly installed water supply pipelines must be pressure tested and there should be no leakage. (The test should be conducted for at least 8 hours after closed irrigation pipe pressure test to maintain the water pressure at least 9KG. If there is decompression, it means there is leakage. This project will be carried out by the general real estate developer.)
2. The drainage pipeline should be temporarily sealed to the original pipeline before construction to prevent debris from entering the pipeline.
3. The installation of the water pipe with the pipe diameter below 25mm shall be installed on the pipe at the corner of the corner, water meter, faucet or angle valve and pipe end 100mm. The installation of the pipe card must be firm.
4. All fittings, valves and pipe connections should be tightly closed, and there should be no leakage. The pipeline has a slope. (Test method: Wipe all joints, valves and piping joints with paper towels when water is used to see if there is any seepage).
5. The installation of water pipes shall not be close to the power supply, and the spacing between water pipes and gas pipes shall not be less than 50mm.
6, the inlet pipe with hot water PPR pipe, plumbing with PVC pipe. Hot and cold water pipes should be left hot right cold.
7, strong wire tube walks the wall, the weak Electric Wire tube walks the ground (or the ground strong and weak electric wire tube walks ground, but must separate 300mm above), the water pipe moves away from the wall as far as possible, the trough should be horizontally straight.
8, the dark line laying must be piped, except for the hollow floor (hollow floor with a sheath line), strong and weak electricity can not penetrate the same pipe. The wires inside the tube should be loose.
9. There must be no joints in the wire conduit. After the completion of the water and electricity, the open ends of all switches and sockets must be wrapped with insulating tape to avoid the risk of electric shock.
10, when installing the power socket, should be left zero right phase (fire), above the ground. Fire line into the switch, zero line into the lamp.
11, the same room of power supply, telephone, television and other socket panel should be at the same level elevation, the height difference should be less than 5mm.
12, bathroom socket should be splash-proof.
13, the power socket is generally 300mm from the ground, switching distance from the ground is generally 1400mm, if special needs are handled according to special circumstances (such as wall-mounted air conditioning socket).
14, the lighting wire is 1.5BV, the socket wire is 2.5BV, the ground wire is 2.5BVR, and the air conditioning and special power wire is 4BV. Air conditioning and high-power appliances should be routed separately.
15. The gas pipe (natural gas pipe) must be removed from the pipe, and it must not be sealed. If it needs to be moved, it must be operated by the gas company.
16, wire, hot water pipes, gas pipes should maintain a certain distance between them, shall not be close.
About acceptance of electricity
1. If there is electricity in the socket panel, it can be tested with the electric pen. Try to find out if there are any problems with all switches, sockets, and mains in the house. Pull down the socket switch in the main switch box. The indicator light is off. Test frequently several times to prove that the switch is well connected and the socket is safe.
2. Power off test. When the gate and meter are outdoors, they should check whether they can control the indoor lamps and the indoor outlets. After the gate is turned on, whether the indoor power is completely turned off; if the gate is open, the gates should also be checked separately. Control each branch line.
3, to see whether the electricity meter, electricity meter installation is currently more than 10 (40) A single-phase power meter, the operation is normal. Or fast or slow should be repaired. The number of meter readings used, because during construction, workers may use your energy, and the money is not the owner.
4, in general, lighting line cross-section area of ​​1.5 square millimeters, ordinary socket line 2.5 square millimeters, air conditioning line 4 square millimeters can be, with a professional rocker or small electrical appliances to test the socket is powered, pay attention to air conditioning holes and air conditioning outlet is and outdoor Air conditioners match.
5. The socket is also used to test whether the ground insulation is in good condition and whether there is a grounding device. The zero-ground voltage should be less than 1V; if it is equal to 0, then the zero grounds may be connected together.
6, usually the fire is mostly caused by electrical accidents, which has a considerable relationship with the setting of the electrical circuit. For the safety and convenience of electricity use, the number of residential circuits per house should not be less than five.
7. The switch in the switch box should be installed firmly. Each must be shaken and checked carefully. If it is found to be loose, it should be fastened or replaced. Otherwise, there will be even greater danger if there is poor contact and fire in future use. Each shunt switch in the switch box should be clearly marked. If not or not clear, correct it immediately during the renovation.
8, check the cable socket, broadband socket, insert it to have no loose or plug into the phenomenon. Check the number of weak electrical outlets, especially don't forget to open the line interface of the phone and TV. Pull it hard to see if it is a virtual one.
9, check the video intercom, emergency call button is working properly.
10, check the entrance doorbell: with 2 5th battery test doorbell. Whether it does not ring or ring.
11. Insurance outlets protect young children. In order to prevent young children from putting their fingers into the socket, the socket must be equipped with a safety device that is located at a height of 30 cm from the ground.
12, bathroom socket rules. The power outlet in the bathroom shall be a moisture-proof socket with splash-proof measures. The lighting lamp holder of the bathroom must be a safe lampholder with a magnetic port. There should be no socket above the wash basin.
About acceptance of water
1, open the tap to see if there is water, how the water quality, whether there is a rust valve affect the water quality, can be replaced by the developer. Check each faucet and observe whether there is any seepage, leakage, or blockage in the upper and lower water pipes. It should be noted that as much as possible, let the water flow be a bit larger and anxious. Let's take a look at the water pressure and try the drainage speed.
2. Check whether the water meter has been installed, whether the water meter is empty, the valve is not closed tightly, the valve is off the wire, and the connector is dripping. The discovery of the empty water meter indicates that the meter is damaged or there may be a leak.
3, copy the water meter figures, this part of the water fee should not be borne by the owners. In addition to recording the data of the water meter, look at whether the water meter moves slowly when all the valves are closed and check whether there is any seepage or leakage in the upper and lower water pipes.
4. Is the toilet water flowing? Is flush sound normal? Is the tank working properly? Many latrines may become clogged or obstructed due to construction waste.
5, waterproof, which is more prone to problems, and once the decoration, the responsibility is not good identification, so be sure to make a good waterproof inspection when the inspection. The first visual inspection to see if the leveling layer 30mm, whether the shower wall 1800mm or more waterproof.
6. Close the water test again, and use a cement mortar to surround a “Uâ€-type threshold of about 10 cm within 25 cm outside the door. Plug the drains of the floor drain and fill it with water (2 cm at the highest point of the terrain). 24 hours Go downstairs and check it out. This test is best performed at the same time as the upper occupants, so that the top and floor of the bathroom can be detected at the same time. Water is released in the toilet and shallow (about 2cm high). Afterwards, the owners who are downstairs are expected to check the ceiling of their home toilet after 24 hours.
7. The floor drain and the flooding slope meet the design requirements, so as not to pour water, the joint is smooth and smooth, and there is no leakage. You can put the table tennis balls on the ground. If table tennis balls roll to the floor drain, you can. When you test, remember to look at them from multiple directions.
8. Top-level residents check for rain. If you are buying a top floor, be sure to check the top surface of each house for waterproofing and traces of rain. Because according to the construction requirements, the houses handed over have either passed the “test†of two heavy rains, or the construction party has conducted rain tests under the supervision of the supervision unit.
Acceptance of upper and lower water pipelines
1. Prerequisites for acceptance The quality of the materials for the drainage pipe and the water pipe must comply with the current national standards. There are the name of the manufacturer, the factory brand, the product certificate, and the warranty book.
2. Acceptance requirements
(1) The pipeline should be installed with special tools. The nozzle must be treated with a standard reamer on the aluminum-plastic pipe at the nozzle end to prevent damage to the inner double-layer guard ring of the copper joint. No leakage shall occur.
(2) All kinds of valve installation positions should meet the design requirements and be easy to use and maintain.
(3) Pipes and pipes and valves shall be tightly connected. The pipes shall be threaded, and there shall be exposed threads at the joints. The pipes shall be fixed in time with the installation completed and no leakage shall occur.
(4) Valves and faucets should be installed in a correct position, flexible and convenient to use, with unobstructed water flow and normal operation of the water meter. Under the premise of satisfying the use, the valve, water meter, etc. may be in a relatively concealed position or surface decoration is appropriate.
3, acceptance methods and common sense
(1) Whether the running direction of the water is correct or not can be determined by visual inspection according to the drawings.
(2) Check whether the two systems of cold and warm water pipes are correctly installed. The general hot water pipes are red. The hot water taps have red marks in the middle of the switches. They can be tested by cold and hot water.
(3) Check the laying of pipes and power supply, gas pipe position, general spacing ≥ 50mm, available tape inspection.
(4) The aluminum-plastic compound pipeline should not be stretched and straightened in the dark deposit. It may leave room for it to avoid the leakage of the hot water through the expansion of the pipeline. You can use visual inspection to determine a slight bend.
(5) Into the wall pipe slightly recessed wall, the construction is the acceptance between the attention and the wall can be flat, otherwise, after the next process will have a sense of external sense of sudden, you can feel touch.
