为使高水头作用下防渗涂层的耐击穿厚度试验更为便利,在已有大型聚脲涂层耐击穿厚度试验装置的基础上,通过技术改进,提出了一种便携式高坝涂层耐击穿试验装置,该装置以大型三轴仪的液压伺服系统作为压力来源,可实时监测与控制水头压力变化,并将该装置应用于聚脲防渗涂层的耐水压击穿试验中。结果表明,改进后试验装置的性能与应用效果较好,满足设计要求。 In order to make the penetration resistance test of the anti-seepage coating under high water head more convenient, on the basis of the large polyurea coating penetration resistance thickness test device, through the technical improvement, a portable high dam coating Layer wear-resistant test device, the device to a large triaxial instrument hydraulic servo system as a source of pressure, real-time monitoring and control of head pressure changes, and the device used in the anti-water-resistant polyurea impermeable coating breakdown test . The results show that the improved experimental device has better performance and application effect and meets the design requirements.
