The Foshan Pipe Segment Factory of China Railway Ninth Bureau Road and Bridge Branch

Background

The Foshan pipe segment factory of China Railway Ninth Bureau Road and Bridge Branch is the first precast pipe segment factory established by China Railway Ninth Bureau. It is located in Shishan Town, Nanhai District, Foshan City, Guangdong Province, covering an area of 100 acres for the factory and 130 acres for the yard. The factory is equipped with 2 pipe segment production lines and 26 molds, with a daily output of 70 rings and an annual production capacity of over 21,000 rings, making it the largest pipe segment supply and dispatching base in the Guangdong region of China Railway.

Project Challenge

To shorten the production cycle and increase output, the factory adopts steam curing for the maintenance of building components, with both the heating period and the constant temperature period being about 3 hours and 5 hours, respectively, and the constant temperature period temperature is 50°C. During these two periods, high-temperature steam needs to be continuously supplied to the curing warehouse to meet the curing temperature requirements, resulting in serious energy consumption.

Solution from ARIT

The factory has replaced the steam curing process with a self-developed early strength high performance water reducing admixture by ARIT, combined with early strength-enhancing nano seeds admixture. Admixture from ARIT helps to achieve a no-steam curing process for pipe segments. This has greatly achieved energy conservation and environmental protection, as well as cost savings.
