Stainless Steel Double Expansion Ring Rubber Repair Technology for Drainage Pipes
For the complex underground drainage network system in cities,due to the long laying time,there have been problems that cannot meet the normal functional requirements.Meanwhile,large-diameter drainage pipelines generally play an important role in urban drainage,making traditional excavation and repair increasingly difficult.Based on various drawbacks,this paper introduces the non excavation stainless steel double expansion ring rubber repair technology,and elaborates on its characteristics and construction process.
