Function of flexible waterproof casing

Function of flexible waterproof casing
During the actual design of the waterproof casing, all components are treated with plugging materials. Therefore, the whole ring structure is basically designed as a font feature. When the surface medium is corrosive medium, plugging material can be used to block it to achieve good installation effect. The four drainage principles of waterproof casing: prevention, drainage, interception and blocking are the principles of waterproofing in human defense projects, which are usually tailored and combined according to the collection of waterproof casing diagrams. What are the functions of flexible waterproof casing? Waterproof casing has a certain function of waterproofing seepage, flow and inflow into the lower layer. Prevention has two aspects. On the one hand, after the completion of the project, the user flows water through the waterproof casing to the lower level due to improper reasons during the renovation phase; on the other hand, after the user enters, the water flows through the casing to the lower level due to unexpected reasons. In addition, the former is usually more frequent than the latter. There are two reasons for the lower flow. First, the wall waterproof casing height is low; second, although the height is sufficient, but the casing mouth is not strictly sealed. Therefore, this specification has strict requirements for the height of the wall waterproof casing: with water room (kitchen, bathroom, etc.), the height of the wall waterproof casing should be 50mm above the surviving floor, and the wall waterproof casing of plastic water supply pipe should be more than 100mm above the surviving floor.
 
The choice of high-fluidity concrete, vibration-resistant concrete and admixtures is the guarantee of that supply. At present, on the one hand, waterproof concrete to control the water-cement ratio, sand ratio and the amount of separate cement to improve the density of concrete and resistance to seepage. In addition, there are more additives, such as water-reducing agents and expansion agents to reduce the impact of concrete. Ghee can reduce cracks and improve impermeability.
