The most important content contained in the hidden project is the water supply and drainage project, wire and cable engineering, as well as the floor base and partition base, among which the hydropower project is particularly important. As a matter of personal safety and property safety, you must not be sloppy!
(1) Renovation Let's first talk about the water supply and drainage concealment project. Check the contents of the following three aspects: 1. Whether the water pipeline leaks water, the installation layout of the pp-r pipe should be reasonable, horizontal and vertical, and pay attention to the pipeline must not be close to the power supply, and the distance from the power supply. The minimum straight-line distance is 0.2 cm. The connection between the pipeline and the sanitary appliance must be tight. No leakage can be achieved through the water test.
2. Whether the floor drainage is smooth or not, 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.
3, waterproof layer waterproof is good, kitchen and back wall in the waterproof requirements are higher than other rooms, waterproof coating brush to 1.8 meters high, other rooms should also be 0.3 meters high.
(II) There are two problems to be noticed in the renovation of the wire and cable works:
1, pvc pipe connection is tight, the power line buried in the wall, ceiling, floor or floor must wear pvc pipe, the pipe should not be combined with kink. 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 laying of the ground circuit, should be placed on both sides of the laying of the pvc pipe wooden side, or with cement mortar for slope protection, to prevent the pvc pipe in the construction of workers walking back and forth due to being trampled. The distance between strong and weak electricity should be about 50 centimeters to reduce the electromagnetic interference between them and prevent accidents.
(C) Renovation of the ground base should pay attention to:
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.
(4) The problem of decorating the grassroots wall:
First, whether Baozhu uses 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, and the dimensions should be consistent with the actual ones, so as to facilitate future maintenance;
Second, whether to do cementing treatment: increase the contact surface of the tiles, and at the same time enhance the friction, so that the ceramic tile is more firmly attached
