Drainage pipeline construction is not only a construction project that causes anxiety during home renovation but also a matter of concern that needs support. What are the specifications of the concrete pipes? 1. Concrete pipes come in various sizes, including 300mm x 35mm x 3000mm, 300mm x 35mm x 4000mm, 400mm x 45mm x 4000mm, 500mm x 50mm x 4000mm, 600mm x 60mm x 4000mm, and 800mm x 80mm x 4000mm, among others. 2. Concrete pipes, also known as pressure pipes or reinforced concrete pipes, can be used as water supply pipelines in foundation construction, for wastewater treatment, flood control and drainage, and as drainage pipes and wells in special industrial and mining enterprises. They are categorized into flat-end reinforced concrete concrete pipes, flexible pipeline reinforced concrete concrete pipes, socket-and-spigot reinforced concrete concrete pipes, F-socket steel pipe ends, flat-end sleeve spigot concrete pipes, pipeline concrete pipes, and more. 3. Concrete pipes are used for the drainage of urban rainwater and domestic wastewater, as well as for the outer casing of pipelines required underground for drinking water, power, communication equipment, and other necessities. They can also be used for vertical and horizontal drainage pipelines and permeable structures on highways. 2. How to install concrete pipes to prevent leakage? 1. Follow the construction standards, including leveling, chiseling, priming, grouting, filling gaps, inserting joints, and compacting and smoothing. The foundation should also be well-prepared. After insertion, the joints should be securely maintained. Early protection is also crucial. 2. Use asphalt felt to fill the gaps, apply a layer of asphalt on the surface, and wrap the joint area with asphalt felt. Apply another layer of asphalt, known as "two oils and two materials." Most visible concrete pipes are treated this way. 3. Check if the pipe is a socket or flat-end pipe, and ensure the joints do not leak, especially in critical areas. It may be better to pour the ground beam first and then install the pipes, ensuring that the branch connections are level. The socket pipe should have an adequate amount of cement mortar padding at the bottom hole. Check the width of the branch pipe around the joint and seal it. 4. To minimize leakage, strictly adhere to construction standards. To ensure a leak-proof installation, use flexible joints. This involves using a rubber sealing ring that comes with the concrete pipe. The sealing ring can be purchased from the supplier when buying the concrete pipes.
