1. Drainage Concealed Works
Whether the water pipe leaks.
The installation layout of PP-R pipe should be reasonable, horizontal and vertical. Pay attention to that the pipe should not be close to the power supply, and the shortest straight-line distance between the pipe and the power supply is 0.2 cm. The connection between the pipeline and sanitary ware must be tight, and there is no leakage after testing the water.
Is the ground drainage unobstructed?
Toilet and kitchen are the main places for drainage, so the ground leveling should have a certain slope (2%) to ensure that the water collects on the ground into a natural flow and finally flows to the floor drain. However, it should be noted that we should not overemphasize the slope simply for the sake of smooth water flow, because the slope is too inclined, which will affect the beauty and anti-skid.
Whether the waterproof layer is waterproof.
The waterproof requirements of kitchen and bathroom and back wall are higher than those of other rooms, and the waterproof paint should be painted to 1.8 meters high, and other rooms should also be painted to 0.3 meters high.
2. Wire and pipeline engineering
Are PVC pipes tightly connected?
When the power cord is buried in the wall, ceiling, floor or floor, PVC pipes must be worn, and there can be no combined kinks in the pipes. At the bend of the wire protection tube, a matching elbow tool or elbow should be used, and there should be no wrinkles.
Protection of PVC pipe
After the ground circuit is laid, wood squares should be placed on both sides of the laid PVC pipe, or cement mortar should be used to protect the slope to prevent workers walking back and forth from trampling on the PVC pipe during construction. The distance between strong current and weak current should be about 50 cm to reduce the electromagnetic interference between them and prevent the occurrence of safety accidents.
3. Foundation
Mainly depends on whether the cement leveling layer on the ground is qualified: first, the uneven ground of the original house should be paved with cement mortar, and the kitchen and bathroom should have a slope, and the slope is also very particular.
Finally, talk about the problem of partition cardinality. First, whether to use red brick walls, cement tension plates, etc. Usually, the construction technology requires that the columns in the kitchen and bathroom should be built with red bricks, and observation ports should be reserved, and the size should be consistent with the actual situation to facilitate future maintenance; Second, whether to do cement roughening treatment: increase the contact surface of tiles, and at the same time enhance friction, so that the tiles fit more firmly.
The order is polite, and buying building materials wins the Apple IPAD.
