塑料输水管道接口试验是根据低压塑料管道输水灌溉工程施工特点和运行条件,以接口材料试验和接口施工工艺为主要研究内容,通过试验筛选出四种接口方法和二种粘接剂材料。试验结果表明,使用粘接剂粘接聚氯乙烯管材和管件其增强效果较好。依椐实测的接口处抗剪强度和承受内水压力指标,阐述了施工工艺技术和适用条件,作为低压塑料管道输水灌溉系统推荐的接口设计参数。 The experiment of plastic water pipeline interface is based on the construction characteristics and operating conditions of low pressure plastic pipelines for water conveyance irrigation. Taking the interface material test and interface construction technology as the main research contents, four kinds of interface methods and two kinds of adhesive materials are selected by testing. The test results show that the use of adhesive bonding PVC pipe and pipe fittings to enhance the better. According to the measured shear strength at the interface and the index of internal water pressure, the construction technology and applicable conditions are expounded as the recommended interface design parameters for low pressure plastic pipelines irrigation system.
