大口径预应力钢筒混凝土顶管(JPCCP)在供排水工程中的应用

Application of Large-diameter Prestressed Concrete Cylinder Pipe Jacking (JPCCP) Application in Water Supply and Drainage Engineering

预应力钢筒混凝土顶管是一种由预应力和非预应力复合而成的新型管道,是大口径压力输送管道类型中的新成员,可应用于开挖和非开挖供排水,尤其在曲线顶管方面具有独特的优势。

Prestressed steel cylinder concrete pipe jacking is a prestressed and non prestressed composite of new pipeline. It is a new member of the large diameter pressure pipeline type, application in excavation and trenchless water supply and drainage, especially has a unique advantage in termsof curve pipe jacking.
