近年来我国发展的喷灌工程,正在逐步地应用国产的塑料管道.在实际使用中经常发生管道破裂和接头处漏水,为此,我们在管道上安装了伸缩节,采用了承插粘接等技术.取得了良好的效果,并在省内喷灌工程中得到推广应用. In recent years, China’s development of sprinkler irrigation projects, is gradually using domestic plastic pipe. In actual use, pipe cracking and joint leakage often occurs, for this reason, we installed expansion joints in the pipeline, the use of socket bonding and other technologies. Has achieved good results, and in the province sprinkler irrigation project has been promoted.
