Retard-bonded prestressed FRP bundle steel cylinder concrete pipeline and production method
The invention discloses a retard-bonded prestressed FRP bundle steel cylinder concrete pipeline and a production method. The retard-bonded prestressed FRP bundle steel cylinder concrete pipeline comprises a pipeline structure consisting of a glass fiber inner pipe, inner-layer concrete, a sieve mesh type steel cylinder, outer-layer concrete, retard-bonded prestressed FRP bundles and a mortar protective layer; and the two ends of the pipeline structure are respectively provided with a bell mouth steel ring and a spigot steel ring, and an adjustable anti-seepage rubber ring is arranged on the inner wall of the spigot steel ring. According to the retard-bonded prestressed FRP bundle steel cylinder concrete pipeline, through the arrangement of the sieve mesh type steel cylinder, the inner-layer concrete and the outer-layer concrete are mutually fused through round holes to form an internal structure similar to a stud, the connecting performance between the steel cylinder and the concrete is effectively improved, the shear bearing capacity of the pipeline is enhanced, and the pipeline is high in shock resistance and compression resistance, good in durability and good in connector sealing performance; and meanwhile, due to the fact that the retard-bonded prestressed FRP bundles are matched with the mortar protective layer, the pipeline has long service life and good leakproofness, and the pipeline is particularly suitable for long-interval water delivery main lines and underground comprehensive pipe gallery engineering of some major cities.
本发明公开一种缓粘结预应力FRP束钢筒混凝土管道及生产方法，包括由玻璃纤维内管、内层混凝土、筛孔式钢筒、外层混凝土、缓粘结预应力FRP束和砂浆保护层构成的管道结构，管道结构两端分别设有承口钢环和插口钢环，插口钢环内壁上设有可调防渗胶圈；本发明通过筛孔式钢筒的设置使得内层混凝土和外层混凝土通过圆孔相互融通形成类似栓钉的内部构造，有效提高了钢筒与混凝土两者之间的连接性能，增强了管道的抗剪承载力，使管道的抗震、抗压性能强，耐久性能好，接口密封性好，同时缓粘结预应力FRP束配合砂浆保护层使得管道具有较长的使用寿命、良好的密闭性，尤其适用于长间隔输水干线和一些重大城市地下综合管廊工程中。
