On the other day, the city sewage governed three issue of projectsPuxi gathering system Luo Gangxiang the road diameter 2 meterscentrifugal types glass tubing the top pipe projectsmoothly to complete, this symbolized Shanghai utilized this kind ofnew technology to obtain successfully for the first time. The glass has the weight light, anti-corrosive, the frictionalcoefficient small, the life is long, the pipeline and the connection intensity higher merit. Governs in three issue of engineeringconstructions in the sewage, the draining water company positiveorganization, coordination engineering construction all quarters,positively explore the glass fiber reinforced plastic top pipein Shanghai soft soil stratum application experience, after this toppipe experiment obtains successfully, the draining water company iscarrying on the technology to this project to summarize, regardingmaintains the Shanghai city underground duct the long-term reliablehigh quality movement to have the important economic efficiency andthe social significance.
