Reinforced concrete drainage pipes have always been the top choice in wastewater pipelines due to their excellent load-bearing capacity and durability. Many underground drainage systems around us are constructed using reinforced concrete drainage pipes. However, a common issue encountered during actual use is leakage at the pipe joints. Next, Tangshan Fengrun Xiangrui Cement Pipe Factory will introduce the methods for dealing with joint leakage.
Ensure the task is completed first, following the construction standards: smooth, grout, apply plaster, seal gaps, insert joints, compact and finish. The basics should also be well-executed. Pay attention to maintenance after inserting the reinforced concrete drainage pipe joints, and care in the middle and later stages is also crucial.
2. The concrete reinforced concrete drainage pipes must be either socket-and-spigot or plain-end pipes to ensure they do not leak. The same basic steps should be followed. The pipes can be installed after the concrete foundation bedding is properly poured, and the branch connections should be detailed. For socket-and-spigot connections, a layer of cement mortar should be placed under the pipe holes to ensure consistent width around the branch pipes. Fill and smooth the gaps to block the pipe seams securely.
3. Sealing pipe joints at the connections of reinforced concrete drainage pipes, standardizing operational procedures, and strictly adhering to the actual construction standards is the only way to reduce leaks. Otherwise, flexible joints must be used, specifically, the rubber strips and gaskets used for the accessories of reinforced concrete drainage pipes. These rubber rings can be purchased together with the reinforced concrete drainage pipes from the supplier.
4. When using asphalt felt to fill the joints, apply a layer of asphalt on the surface first. Then, at the concrete rain and sewage pipe joints, wrap the joint area with asphalt felt within the total width range and apply another layer of asphalt. This is what we refer to as "two oils and two materials." The reinforced concrete drainage pipes we see are generally handled in this manner.
