In all decoration projects, the budget of hydropower materials must be taken into account to avoid unnecessary expenditures. As a concealed project, hydropower reform is the most important aspect of renovation and is also the beginning of renovation. It is also the main profit point of home improvement companies. one. Secondly, there are many places that need to be paid attention to in the inspection and acceptance of the house. At present, the inspection and acceptance of the home improvement project is based on the relevant decoration acceptance standards. The decoration company should carry out the quality inspection according to this minimum standard. The hydropower project is not up to the standard. If quality problems are not discovered in time, it will be very troublesome to rework it later. Therefore, for the home improvement check, strict acceptance of the hydropower project is an essential part of the renovation. That's where Xiao Bian talked about what needs to be paid attention to in the inspection and acceptance of water and electricity , as well as the list of prices of water and electricity materials . I hope to help everyone.
Water and electricity renovation acceptance what need to pay attention to matters
As with the acceptance of all projects, the acceptance of hydropower must first be carried out on the acceptance of materials and the acceptance of appearance. Check whether the specifications of the water pipes, bushings, wire rods, etc. used in the water and circuit reconstruction are the same as the specified materials. All materials purchased must meet the national testing standards to prevent product failure.
The second is to examine the layout and construction of the water circuit to see if there are any scratches on the surface of the material, and then check the installation of the line and the pipeline, and whether the alignment is consistent with the original design drawing. Make sure all outlets and outlets and drains are in the correct position. Check whether the positioning of the inspection and cassettes meets the requirements of symmetry and consistency. If there is a change in the layout of the pipeline, it is important that the construction party provide a copy of the water and electrical wiring diagrams after the renovation.
Circuit acceptance points:
Circuits have the same impact on life as waterways, and they add a bit more danger than waterways. Therefore, the acceptance must be more stringent.
1, strong and weak electricity should be separated
The family usually uses AC power. Some construction teams directly store all the wires together for the convenience of construction. Power lines, network cables, telephone lines, etc. are all placed in the same bottom so that the lines can be disturbed and the signals are not affected. stable. It will also lay a hidden danger for home fires. The strong and weak electricity should be routed separately. It is strictly forbidden to share one pipe and one bottom box for strong and weak electricity. The parallel distance of strong electricity lines should not be less than 3cm, preferably 50cm, and the crossing must be a right angle.
2, wire and casing
Some irresponsible construction parties will directly bury the wires in the wall during construction. The wires are not covered with insulating tubes, and the wire connectors are directly exposed. This can easily cause safety hazards and is a typical phenomenon of cutting corners. The specification of the laying of wires is clear and there must be protection of the insulation sleeve outside the wires. The joints cannot be exposed. Pay special attention to this when checking.
3, check whether the socket wire is installed arbitrarily
Many families use slotting and dark pipe laying for aesthetic reasons. When wiring, we must follow the "fire line into the switch, zero line into the lamp" principle, but also set leakage protection device on the socket.
Waterway inspection points:
There are many matters needing attention in the waterway construction. When checking, you can compare the construction precautions and check whether the waterway in the home meets the specifications.
1. Location of hot and cold water pipes: The installation of hot and cold water pipes follows the rules of “heating and cooling, left and right coolingâ€. The pipes installed above and below must also pay attention to the parallelism between the two pipes. If the water pipe is close to the gas pipe, the distance between the two pipes must be greater than 50mm.
2, water pipe fixation: laying a good section of pipe, the pipe must be fixed. So as not to lay a good pipe position shift, causing unnecessary trouble.
3, water and gas location: the installation of water pipes shall not be close to the power supply, the spacing between water pipes and gas pipes shall not be less than 50mm.
4, pipe regulation: check the direction of the upper and lower water should be reasonable, horizontal and vertical layout, there is no excessive corners and joints.
5. Attachment installation: Check whether the accessories are tightly connected and have no leakage; whether the water outlet is smooth or not, and whether the water meter is running normally.
6, pressure test: After the waterway transformation done, must do the pressure test of the water pipe, which is the common method to ensure the reliability of the water pipe connection in the later period. The pressure test is generally completed by the decoration company, the owner and the project leader.
