玻璃钢管道铺设过程中的重点。

     一、玻璃钢管道管沟底部不平,存在障碍管线的硬土块、石块等尖锐的硬物。一般来说,低洼地带的管沟都采用机械开挖,由于地势较低,管沟底部潮湿或者上水,存在硬物的可能性很大,主要是碎石、砖块和障碍管线等硬物,特别是在管沟上水量较大,这些硬物存在于水面以下时,不容易被发现。当玻璃钢管道在水面上安装完成以后直接回填,导致玻璃钢管道直接压在硬物上,也许短时间内由于回填土疏松不会损坏,但是由于回填土的下沉与压实,管道投产以后,管道的内部压力作用及内部液体流动导致管道的微震动,随着时间的增加,硬物对玻璃钢管道所造成的点载荷作用越来越大,玻璃钢被硬物所作用的点必将损坏。另外,管沟沟底高低不平会造成管道受力不均,回填时,高起的地方会产生应力集中。损坏管道或造成不必要的磨损。在管道系统中有脉动压力时,这种磨损更为严重。
