How to Solve the Issue of Leaking at the Joints of Cement Drainage Pipes

We all know that Zhengzhou cement drainage pipes are a type of pipeline used for underground drainage. They are used everywhere in our daily lives. So, how can we address the issue of leaks at the joints of cement drainage pipes? Let's take a look together below.

How to Solve the Leak Problem at the Joint of Zhengzhou Cement Drainage Pipes

Construction should be carried out according to specifications, including cleaning, chiseling, priming, filling gaps, joining, compacting, and smoothing. The foundation must also be well-prepared. Post-joint care is essential, and ongoing maintenance is crucial.

Zhengzhou cement drainage pipe manufacturer uses asphalt cotton to fill in the joints, applies a layer of asphalt on the surface, then wraps the joint area with bituminous felt, and covers it with another layer of asphalt, which is referred to as "two oils and two materials." The highway culvert pipes we see are generally treated in this manner. Depending on whether it's a socket pipe or a flat-end cement drainage pipe, ensure it doesn't leak. The same foundation work needs to be done: first, pour the concrete base layer and then install the pipe, making sure the pipe ends are flush. For socket pipes, place an appropriate amount of mortar at the bottom to ensure the uniform width around the pipe mouth. Seal the joints with mortar to tightly block the pipe seams. Pour pipe bands to seal the joints, operate according to specifications, and only by strictly following the construction operation standards can leaks be minimized. To prevent leaks, a flexible joint is required, using rubber strips and gaskets supplied with the cement drainage pipes. These gaskets should be purchased together with the cement pipes from the supplier.

What causes the white discoloration in Zhengzhou's cement drainage pipes?

Alkali efflorescence primarily manifests as the reaction between the strong alkali in the strongly alkaline cement used for adhesion and the acidic solutions in the air, typically acid rain or industrial and domestic acidic substances like carbonates. These reactions produce salts, which are then carried to the surface of the tiles by the water. Once the water evaporates, these salts appear as crystallized formations on the surface of the cement drainage pipes or at the joints. The basic reaction is acidic solution + alkali = salt + water. The resultant sodium salts are easily soluble in water and, upon encountering sufficient water, form an ionic solution, quickly leaving the original salt location and diffusing to other parts of the tiles and stone. As the water dries, the salts re-crystallize in the diffused areas, leading to new instances of efflorescence and salt precipitation.
