Precautions for hydropower

1. Precast floor slab of second-hand house should avoid slotting pipes on the basis of the original floor slab as far as possible to prevent the old building from being damaged by large vibration during construction.

2. It is not advisable to slot the jumper on the ground at will to avoid the pipeline area; It is not advisable to drill holes in the ground to fix the pipeline at will, so as to avoid the pipeline area.

3. When opening the tape, avoid the reinforcement. You can move it up and down and even change its position. It is forbidden to break steel bars.

4. It is forbidden to open a long horizontal slot on the wall to walk the electric tube. The load-bearing wall is easy to damage the structure, and the long-distance reinforcement breaking of the light wall will still cause future troubles.

5. Without special circumstances, the catheter should not be placed in the plastering line, which is prone to dead bends and dead lines.

6. The pipe bender is used to turn PVC cold-formed conduit with a pipe diameter less than 25MM, and no elbow can be added when turning.

7. It is forbidden to use three-way wiring for the walking tube, so it cannot be maintained in the later period.

8. After laying the PVC conduit, it is necessary to glue the interface with PVC.
