【 Weak current College 】 decoration project check in hiding

Hidden project contains the most important content is the water supply and drainage engineering, wire and pipeline project, plus floors such as grass-roots, wall base, with hydropower project is particularly important. Although this is a decoration of wood, but as your home, personal safety, property, security issues, you can never afford not to! read more advance surely learn more.
Built-in works for water supply and drainage, to check three aspects:
1. pipe line leakage
First of all, the PP-r pipe installation layout should be reasonable, horizontal even vertical, and takes note of the pipeline allowed * near power, and power distance shortest linear distance 0.2 cm, pipeline and health apparatus must close the connection, the water test no leakage.
2, surface drainage is smooth
The bathroom, the kitchen is the main drainage, land leveling a certain slope (2%), ensure that the water in the ground into the natural water flow and eventually flows into the floor drain. But it should be noted that cannot simply in order to flow smoothly while too emphasised too steep slope because angled, affect beauty and slip resistant.
3. If good waterproof waterproof
Kitchen and back walls in waterproof requirements than other rooms, waterproof paint brush to 1.8 m high, other room should also be 0.3 metres high.
Wire and pipeline project, also have 2 issues require attention:
1. PVC piping connection is close
Power cord into the wall of the burial, ceiling, flooring or floor must wear in PVC pipe, pipe should not have the combination of kink. Cable protection pipes bend should use supporting bend tool or supporting elbows, there should not be folded.
2. protection of PVC pipe
Laying in ground circuit, should be laid on both sides of the PVC pipe, wooden side placed or cement mortar do pitching against PVC pipe construction workers in the aisle and being stepped on. ELV spacing should be about 50 cm to reduce electromagnetic interference between them, and can prevent accidents can occur.
Ground-level
The main attention should be paid to whether ground cement screeds should competent: first the original room ground unevenness of local paving with cement mortar, kitchen should have the slope and slope is also very high.
Last mention partition grass-roots of the problem. Whether one is a pillar in red brick, cement rally plates, etc. Usually the process requirements of the construction of the boat in the kitchen room package string must be enclosed in red brick walls, and set aside the mouth size to observation and practical, for future maintenance; the second is whether cement la wool processing: increase the contact surface of tiles, while enhancing friction so that more solid ceramic tile adhesive.
