Our customer ZG engineering ltd won a bid to build one road,the total length is 21.36km. There are four pipelines installed in parallel along the pipeline project, totaling 114km.Since Ethiopian market does not have a ready-made reinforced concrete drainage pipe manufacturer, it cannot be purchased directly from the market.In addition, the soil in the construction area is dominated by black cotton soil (black expansive soil) unique to Africa. The black cotton soil is strongly expanded in water and the expansion coefficient is between 15% and 25%. According to the relevant requirements of the British BS specification, this kind of earthy pipe must be installed with a flexible interface, and the socket-reinforced concrete pipe is a kind of pipe that uses a rubber ring as a sealable flexible interface material.so our Reinforced Concrete Pipe Making Machine was installed and started to produce Socket concrete pipe,The number of various pipe diameters required as below:
Advantages of socket concrete pipe:
The socket concrete pipe is different from the contour structure of the flat cement pipe in that there is one more socket and socket at both ends of the pipe, and each of the socket inner wall and the socket outer wall has a working surface for installing a sealing rubber ring.As the socket mouth concrete pipe adopts the rubber ring as the sealing flexible interface, it can effectively avoid the cracking and leakage caused by the twisting of the pipe interface due to uneven foundation sinking. At the same time, due to the elimination of the process of the concrete foundation cushion of the flat mouth pipeline and the interface cement mortar wiper, the rapid construction of the pipeline was realized. Therefore, it has been widely used in recent years.
