The utility model discloses a concrete pipe with reinforced lining, including a pipe body, in which a glass tube is arranged, a resin layer is arranged between the pipe body and the glass tube, a step hole is formed by a depression on the inner wall of the right end of the pipe body, a step shaft is formed by a bulge on the outer wall of the right end of the glass tube, and the outer diameter of the step shaft is equal to the step hole so that the step hole can be made. The left end of the FRP pipe is shorter than the left end of the pipe body. The FRP pipe extends out of the right end of the ladder shaft at the transition part whose outer diameter is equal to the inner diameter of the pipe, and the transition part is prominent at the right end of the pipe body. The FRP pipe not only ensures the load-bearing capacity, but also has the anticorrosion effect; when some concrete pipes are connected with each other, the FRP pipe undertakes the connection of concrete pipes, further utilizing the advantages of high strength of FRP pipe itself to prevent the dislocation of concrete pipes; the stepped shaft and the stepped hole are designed to enable the FRP pipe to be assembled with concrete pipes. Natural locking position. The utility model is applied to the field of underground drainage pipes.
【技术实现步骤摘要】
一种增加加固内衬的砼管
本技术涉及地下排水管领域,特别是涉及一种增加加固内衬的砼管。
技术介绍
有一些埋于地下的管件,内部通常走线或输送流体,管件横向纵向都受到力的作用,所以对管件的承载抗拉能力有相应的要求。传统的以混凝土为基材的砼管在首尾连接时通常是直接对接插入,然后在管件的轴肩处上上螺栓连接,这种做法目前有一个缺点是相邻两管件容易发生滑脱错位,虽然偏差不大,但对于输送流体的管路来说,会使流体泄露。目前比较合理的做法是采用环箍抱箍的方式卡住相邻两管件,但管件径向上又不能承受太大的锁紧力以免两端向中间塌陷,若先能提高砼管的强度则为最好。
技术实现思路
本技术的目的在于提供一种通过插入高强度材料的圆管,作为加固内衬加入的砼管。本技术所采取的技术方案是:一种增加加固内衬的砼管,包括管体,管体内设有玻璃钢管,管体和玻璃钢管之间设有树脂层,管体的右端内壁凹陷形成阶梯孔,玻璃钢管的右端外壁隆起形成阶梯轴,阶梯轴的外径等于阶梯孔使阶梯孔能够收纳阶梯轴,玻璃钢管的左端短于管体的左端,玻璃钢管在阶梯轴的右端延伸出外径等于管体内径的过渡部,过渡部突出于管体的右端。作为上述方案的改进,管体内 ...
