摘　　要：柔性接头管道在转弯处须浇筑砼止推墩，若从接头上改进，研制卡环式能承受拉力的接头是比较理想的。本文介绍了预应力钢筒砼压力管上止推装置的设计及应用情况，从止推座、止推接头及其型式均有阐述。Concrete thrust blocks should be poured at the bent of pressure pipe line with flexible joints.It cliprings are used to resist tension force,this amendment joint will realize its ideal.Design and application of pressure pipe thrust anchorage of PCCP are introduced in this paper.The discriptions of thrust block joint and its types are available for relevant personns reference.
