The acceptance inspections of hydropower projects mainly include inspection during the construction process and inspection of the delivery.
I. Inspection during construction
For those processes that will have a serious impact on the entire process if the construction fails, it must be checked after it is completed. Such as kitchen and bathroom waterproof, buried underground water and electricity pipelines, after the construction of the floor tiles found that water is not qualified, the wiring pipeline is not connected, plumbing pipeline is not connected or water leakage, it can only be reworked.
Second, inspection
1. The wire conduit should be unblocked, and the conduit wire should be drawn back and forth by hand. It should be able to twitch so that the damaged wire can be replaced later.
2. Check the socket wire sequence with the electric pen or socket detector. It must be left zero and right fire on the ground.
3. Check the switch wire sequence with the electric pen. The switch must control the fire wire.
4. Check the test button of the leakage protector or check the leakage protector with the socket detector. The operation must be flexible.
5, using the insulation resistance meter to detect the insulation resistance of the loop is not less than 0.5M ohms.
6, open the main valve, hand touch to the drainage pipe joints to be tight, no water leakage, drainage should be smooth.
Acceptance inspection must pay attention to the preservation of the water circuit construction drawings, and require the drawings and the actual to be consistent with each other, because the drawings are the basis for future maintenance, but now most owners ignore this.
