During the renovation, the concealment project is the most difficult to accept and it is also the most vulnerable place. If the decoration is not good, it will have a very serious impact on the future of home life. Therefore, everyone must be familiar with the hidden project knowledge in advance to prevent the situation. The so-called hidden projects refer to the four major projects of drainage, wire management, ground base, and partition base.
First, whether the drainage concealment project is qualified
1, whether the water pipe leaks
PP-R pipe installation layout should be reasonable, horizontal and vertical, and pay attention to the pipeline shall not be close to the power supply, and the distance between the shortest distance from the power supply is 0.2 cm, the connection between the pipeline and the sanitary appliance must be close, and no leakage can be found through the water test. Otherwise, there will be more trouble in the future.
2, whether the surface drainage is smooth
Toilets and kitchens are the main places for drainage, so the ground leveling should have a certain slope (2%) to ensure that water collects on the ground into natural water flow and eventually flows to the floor drain. However, it should be noted that the gradient cannot be overemphasized for the sake of smooth water flow, because the slope is over-sloped, which can affect the aesthetics and non-slippage. So this is a technical job.
3, waterproof layer waterproofness is good
Kitchen and back walls are higher than other rooms in terms of waterproof requirements. Waterproof paint should be brushed to 1.8 meters high, and other rooms should be 0.3 meters high.
Second, whether the wire and cable project is qualified
1, PVC pipe connection is tight
Power lines must wear PVC pipes when they are embedded in walls, ceilings, floors, or floors. There should be no kinks in the pipes. The bent position of the wire protection tube should use the matching elbow tool or matching elbow, and there should be no folds.
2, PVC pipe protection
After the ground circuit is laid, wood shall be placed on both sides of the laid PVC pipe, or slope shall be made with cement mortar to prevent the PVC pipe from being walked over due to walking back and forth during the construction of the worker. The distance between strong and weak electricity should be about 50 centimeters to reduce the electromagnetic interference between them and prevent accidents.
Third, whether the ground floor is qualified
Mainly to see whether the ground cement leveling layer is qualified: First, the uneven place of the original room should be paved with cement mortar. In addition, the kitchen and bathroom should have slope, and the slope is very particular.
Fourth, whether the partition wall is qualified
The problem of the grassroots division of the partition wall is whether or not the column is covered with red brick walls, cement pull plates, etc. Usually, the construction process requires that the pillars of the kitchen and bathroom rooms must use red brick walls, and reserve the observation port, the size must be consistent with the actual, easy to repair in the future; second is whether to do cement coating processing: increase the contact surface of the tiles, and enhance Friction makes the tile more secure.
