[home decoration network] the main contents of concealed works of home decoration are water supply and drainage works, wire and pipeline works, as well as floor base course and partition base course, among which hydropower engineering is particularly important. Although this is the work of the decoration company, as your home, it is related to personal safety and property safety. Don't be careless

I. concealed drainage works

1. Whether the water pipe leaks. The installation layout of PP-R pipe should be reasonable, horizontal and vertical, and pay attention to that the pipeline should not be close to the power supply, and the shortest straight-line distance between the pipeline and the power supply is 0.2 cm. The connection between the pipeline and sanitary ware must be tight, and there should be no leakage after water test

2. Whether the ground drainage is smooth. Toilets and kitchens are the main places for drainage, so the ground leveling should have a certain slope (2%), so as to ensure that water converges with natural water flow on the ground and eventually flows to the floor drain. However, it should be noted that the gradient should not be overemphasized simply for the sake of smooth water flow, because excessive gradient will affect aesthetics and skid resistance

3. Whether the waterproof layer is good. The waterproof requirements of kitchen, bathroom and back wall are higher than those of other rooms. The waterproof coating should be painted to 1.8m high, and other rooms should also be 0.3m high

II. Wire and pipeline engineering

1. Whether the PVC pipeline is tightly connected. When the power line is buried in the wall, ceiling, floor or floor, it must pass through PVC pipe, and there should be no binding kink in the pipe. At the bend of the wire protection pipe, the supporting bending tool or supporting elbow should be used, and there should be no wrinkles

2. Protection of PVC pipe. After the laying of the ground circuit, wooden squares should be placed on both sides of the laid PVC pipe, or cement mortar should be used as slope protection to prevent the PVC pipe from being trampled by workers walking back and forth during construction. The distance between strong and weak electricity should be about 50 cm to reduce the electromagnetic interference between them and prevent safety accidents

III. the base course of ground and wall

mainly depends on whether the ground cement leveling layer is qualified: first, the uneven ground of the original room should be paved with cement mortar. In addition, the kitchen and bathroom should have a slope, and the slope is also very particular

finally, let's talk about the problem of partition base. First, whether to use red brick walls and cement tension plates for wrapped columns. Generally, the construction process requires that the wrapped column in the kitchen and bathroom room must be built with red bricks, and the observation port must be reserved, and the size should be consistent with the actual situation, so as to facilitate future maintenance; The second is whether to do cement roughening treatment: increase the contact surface of the tiles, and enhance the friction at the same time, so that the tiles adhere more firmly
