摘要
该文对预应力钢筒混凝土顶管(JPCCP)在大口径压力供水工程中的应用作了探讨。预应力钢筒混凝土顶管(JPCCP)是一种综合利用钢材的抗拉、抗渗性能和混凝土抗压性能,采用预应力和非预应力工艺生产的复合管材,是在预应力钢筒混凝土管(PCCP)的基础上研制、开发的一种大口径更新换代产品。经分析研究与比较,认为:适合于非开挖大口径压力输水和污水压力输送工程。
The article discusses the application of JPCCP in the large-diameter pressure water supply projects. The JPCCP is a composite pipe produced by the pre-stressing and non-pre-stressing technologies with the tensile strength, impermeability and compressive performances of concrete, and is a large-diameter updated product researched and developed on the basis of pre-stressed cylinder concrete pipe(PCCP). The analysis, study and comparison show that it is suitable for the unexcavated large-diameter pressure water conveying and sewage pressure transportation engineering.
