The utility model discloses a glass fiber reinforced plastic composite pipe jacking, which is not easy to aging, has high impact strength, and has a firm internal connection of the pipe jacking. The utility model relates to a fiberglass reinforced plastic composite pipe jacking, in which the inner part of the pipe is a cavity passage, and the wall of the pipe body is a lining layer, a fiberglass winding layer, a wire mesh lining layer and a reinforced concrete layer from the inside to the outside. The inner lining layer is composed of a surface felt, a knitted felt and a mesh cloth stacked from the inside to the outside, and a fiberglass winding layer is formed on the mesh cloth. A wire mesh lining layer composed of a number of ring-shaped wires is wound on the winding layer, and a number of ring-shaped wires are arranged at equal intervals. A bending section is arranged on the ring-shaped wire, and the bending section is located on the same side. The bending section is embedded in the reinforced concrete layer. An expansion rubber groove is arranged on the mouth end, and a water-encountering expansion rubber ring is arranged in the expansion rubber groove, and a steel sleeve ring is arranged on the outer surface of the bearing end.

一种玻璃钢复合顶管
本技术属于管道
,具体地说是涉及一种玻璃钢复合顶管。
技术介绍
现有的顶管一般采用钢管或混凝土管道,其缺点是笨重,不容易吊装和下管,容易老化,耐腐蚀性能差;或者采用玻璃钢顶管,其整体成本高,抗冲击强度低。
技术实现思路
本技术的目的是提供一种玻璃钢复合顶管,其不易老化,抗冲击强度高,顶管内部连接牢固。为解决上述技术问题,本技术的目的是这样实现的:一种玻璃钢复合顶管,包括管体,管体内部为空腔通道,管体的一端为插口端,管体的另一端为承口端,管体壁从内到外为内衬层、玻璃钢缠绕层、钢丝网内衬层、钢筋混凝土层,内衬层由表面毡、针织毡、网布从内到外堆叠而成,网布上缠绕有玻璃纤维形成玻璃钢缠绕层;玻璃钢缠绕层上缠绕有若干环形钢丝构成的钢丝网内衬层,若干环形钢丝等间距排列,环形钢丝上具有折弯段,折弯段位于同一侧,折弯段嵌入钢筋混凝土层中;插口端上设有两楔形橡胶槽,两楔形橡胶槽内分别设有一楔形橡胶圈,承口端上设有一膨胀橡胶槽,膨胀橡胶槽内设有遇水膨胀橡胶圈,承口端的外表面上套有钢套环。在上述方案的基础上并作为上述方案的优选方案:折弯段为三角形。本技术相比现有技 ...
