Study on waterproofing Property of Composite Sealing Rubber Strip with Putty for Underground Infrastructure Joints
The assembled underground reinforced concrete structures are an important research direction for the underground space structures.The interfacial waterproofing performance between precast segments is an important factor that affects its normal use, safety and life span.At present, it is common to use waterproofing rubber strip in design worldwide.During installation process, certain compressive stress applied to the strip so.that the strip can achieve the designed waterproofing ability.In this paper, the lateral constraint compression test was carried out of a new type of composite rubber seal strip with putty.A special type of waterproofing and sealing test is designed to study the corresponding relationship of water pressure with compressive force.In this study, the waterproofing test of full-scale tunnel joints was carried out.The research work of this paper provides a scientific reference for the engineering application and design of the composite sealing rubber strip with putty for underground structures.
