摘要
橡胶止水带施工因止水材料本身尺寸限制,多数情况下需要采用硫化热粘接进行施工,因此接头部位就成了止水的最薄弱部位.按照相关规范,标准接头试验样品需要加工成无帮条的工况,而现场实际情况是接头部位均采用了帮条进行强化.以涡河蒙城水利枢纽橡胶止水带施工为例,从无帮条、有帮条工况、不同的接头形状、宽度以及不同的夹持方式,进行了全面的对比分析试验,为工程后期止水接头施工,提供更优的工艺做指导.
In most cases,due to the limits of the size of water sealing material,rubber sealing strips need to be bonded through vulcanized thermal adhesion in engineering projects.Therefore,the joints become the weakest parts to prevet water leakage.According to relevant engineering norms,a standard joint experimental sample shall be without reinforced strips-free.For this reason,jointing parts need to be reinforced with strips according to actual conditions.Taking the application of rubber sealing strips of Mengcheng Water Control Project in the Wohe river as an example,this paper conducts thorough comparative analysis and experiments on various conditions,including reinforced strips or not and different shapes,widths and bonding methods of joints,aiming to provide better technical guidance for the bonding of water sealing joints in the later phases of the project.
