How does the hydropower reform verify the acceptance of water supply and waterway? 1. The inspection and acceptance of home-installed waterways is based on the acceptance criteria for building water supply. There are no specific express provisions for the acceptance of home-installed waterways in the industry. Acceptance methods for general residential houses are:
(1) Connect all hot and cold water supply pipes in the room through a hose to make it a loop. The pipe is filled with water (air) and close the door to control the total water supply valve switch (required to close the valve strictly, otherwise the data is inaccurate, such as the total valve seepage Then another method is used) to use manual or automatic test pressure test pressure pump, the experimental pressure is 1.5 times the working pressure, under normal circumstances is 0.8MPa, within 30 minutes the pressure drop does not exceed 0.05MPa at the same time check the joints can not leak qualified. In case of double-storey or multi-storey villas' experimental water pressure, the experiment time can be extended appropriately.
(2) Water outlets at the outlets are tested by water pressure test and attached with an authoritative source “Test code for construction quality acceptance of building water supply, drainage, and heating engineeringâ€. The key to daily test methods for home improvement is certain changes in time and test values. The results are consistent. of.
4.2.1 The water pressure test of the indoor water supply pipeline must meet the design requirements. When the design is not specified, the test pressure of the water supply piping system of various materials is 1.5 times the working pressure, but not less than 0.6 MPa.
Test method: metal and composite pipe system under the test pressure observed for 10min, the pressure drop should not be greater than 0.02MPa, and then down to the working pressure for inspection, should not leak; plastic pipe water supply system should be stabilized under the test pressure 1h, the pressure drop shall not exceed 0.05 MPa, then the voltage shall be regulated for 2 hours under the condition of 1.15 times the working pressure, the pressure drop shall not exceed 0.03 MPa, and at the same time, no leakage shall be detected at each joint.
4.2.2 The water supply system must be tested and recorded before it is delivered for use.
Drainage and Waterway Acceptance 1. A new sewage pipe is used for irrigation experiment, drainage is unimpeded, the wall of the pipe is not leaked, and no leakage is found. 2. The finished pipe protection is finished after the water pipe is finished to prevent damage caused by man-made foreign object secondary impact.
Circuit acceptance test 1. The acceptance of the new circuit in the new house is confirmed by the acceptance of the display panel or the digital tester.
The lighting adopts lighting test. For homes that are completely rewired indoors, such as villas and old houses (second-hand houses), the system needs to use a 500V insulation resistance meter to test the insulation resistance value. According to the standard, the grounding protection should be reliable, and the insulation resistance between the conductors and the conductor to the ground should be greater than 0.5MΩ.
2. Weak current test Weak current test can use the analog or digital multimeter test signal to switch off. For network and other multi-core signal line testing, special testers can be used for other considerations in test and acceptance (some projects have been described in the construction standards, this No longer listed separately
1. Check whether the results of the hydropower reform and completion of the design plan have been missed, and check the gaps in time.
2. Verify whether the deviation amount of the settlement work amount and the budget work amount exceeds 10% in case of no change in the construction.
3. Number and type of statistical switch socket panel of water and electricity construction personnel, submitted in writing to the owner. 4. Wire joints are firm, and the line heads are not allowed to be exposed. 5. The distance between the center of the mixing valve for the bath and the outlet of the bath is 15 CM. The distance between the centers is 10cm, and the water outlet is consistent with the depth of the wall. The horizontal error at the outlet is the same.
6, test the depth of the outlet pipe water pipe error, the horizontal error of the outlet level must be level with a horizontal bead to the outlet test, horizontal beads is appropriate. After the test is completed, it is necessary to do a handover procedure to prevent hammering of the nozzle during construction.
7. At least one temporary construction socket panel is left for each independent room, and a temporary construction faucet needs to be installed after the completion of construction.
8. The electric pipe and the water pipe can not be in the same slot. If the space is limited, it is necessary to do the cement mortar beam between the water pipes. 9. The junction box with wire joints can't be directly backfilled with cement mortar or gypsum materials. Reserve a good access port. , The bathroom electric pipe generally goes to the top, if not avoided, the ground PVC electric pipe must ensure that the entire pipe is not jointed.
Installation considerations for water and electricity Electrical installation 1. Installation of luminaires (1) When the weight of the luminaire is more than 3kg, it shall be fixed on bolts or embedded hooks;
(2) Soft-wire chandeliers, when the lamps and lanterns are important 0.5kg or less, the soft-wire self-suspension is used; the lamps larger than 0.5kg adopt the hanging chain, and the soft-wires are forked in the hanging chain, so that the wires are not subjected to force;
(3) The light fixture is firm and reliable, and no wooden wedge is used. There are no less than two screws or bolts for each fixture.
The rest refer to “Construction and Acceptance Specifications for Electrical Installations of Electrical Installation Engineering†2. Power switch, socket installation (1) Horizontal mounting socket, facing the right pole connection line of the socket, the left pole is connected to the neutral line, the upper grounding line .
(2) Wiring: Leave the wires thrown out of the box for maintenance length (15-20CM) to cut off the insulation layer, taking care not to injure the wire core, such as the switch, the inside of the socket as the terminal, and coil the wire in the clockwise direction. On the corresponding terminal of the switch and socket, tighten the pressure head. If the switch or socket is a plug terminal, insert the core back into the round hole terminal (when the hole is allowed to press the double wire), and then press it with the top wire. Note that the core should not be exposed.
(3) The installation height of the socket shall comply with the design requirements. When the design is not specified, the following requirements shall be met: The socket for concealed installation shall not be less than 0.3 meters from the ground, and the concealed socket in special places shall not be less than 0.15 meters. Safe outlets should be used in children's activities. When using an ordinary socket, its installation height should not be less than 1.8 meters.
(4) Special attention: In order to avoid AC power interference to the TV signal, there should be a distance of 0.5m or more between the TV feedline tube, socket and the AC power line tube and socket (in special cases, the signal cable is shielded. The spacing must not be less than 0.3m).
(5) In damp places such as bathroom and kitchen, waterproof and moisture proof sockets with good sealing should be used.
(6) The same type of parallel installation and the same installation height of the same indoor switch, and the control of a good order. The sockets installed side by side are not less than 20 mm apart from each other.
