笔者在多年的施工中发现，硬质塑料管常出现断裂、真空破坏、接口渗漏、砂眼漏水、内壁裂纹以及树根影响等问题，降低了工程的正常输水能力。因此，加强对节水灌溉管道在施工中常见问题及其预防对策的研究，提高管道经济运行寿命，对于降低运行管理费，提高工程效益，保证管网 The author found in many years of construction, hard plastic pipe often rupture, vacuum damage, interface leakage, trachoma leaks, wall cracks and root problems and other issues, reducing the project’s normal water delivery capacity. Therefore, to strengthen the water-saving irrigation pipe in the construction of common problems and preventive measures research to improve the economic life of the pipe life, reduce operational management fees, improve engineering efficiency, to ensure that pipe network
