Background technique
Urban drainage pipe network is the important component part of urban infrastructure; the management of urban drainage pipe network is significant to the protection of urban environment, urban construction and economic development; being the important symbol weighing urban modernization management, is also the important leverage facility of Urban Water Pollution Control and drainage waterlogging prevention.At present, more at the subsoil drain total length about 5.8 ten thousand kilometers that China is on active service more than 20 years, there is the phenomenon such as seepage, corrosion in these old pipelines, will be easy to cause the accidents such as road landslide, pipeline burst once be subject to external disturbance.The non-excavation repairing technique of current China independent development cans be counted on one's fingers, and the case adopting non-excavation repairing technique to carry out water supply and drainage pipeline rehabilitation is also few, and within 2009, China's drainage pipe adopts the length of non-excavation repairing technique only to have 27.92km.For Beijing, 2006 ~ 2007 years, transform last century 50, the drainage that is about 30km the sixties, part have employed trenchless technology and constructs, and length reaches 8km, and non-excavating construction amount accounts for 27% of total length.And external as the U.S. since two thousand five, trenchless technology is changed at drainage pipe and is reached more than 65% with the application in reparation.
Along with the progress of Chinese Urbanization, urban architecture density and urban road load increase day by day, especially some old towns, under ground piping is staggered complicated, a lot of pipeline position is failed to understand, carries out drainage pipe reparation, easily cause various engineering technology problem according to the method for pipe laying again after excavation.Trenchless sewer repair technique has and reduces traffic impact, trouble of avoiding removing, reduces environmetal impact, avoids the series of advantages such as roadbed subsidence or seeping phenomenon generation and be subject to the attention of Industry regulatory bodies.General Office of the State Council's " instruction about strengthening City Buried Pipeline implementation management " points out: started from 2014, complete the old pipe network improving of Urban Underground with 5 years; Comparatively perfect City Buried Pipeline system was built up with 10 year ten years.Therefore, the mismatch pipeline in-situ repairing device developing a kind of no-dig technique is a problem demanding prompt solution.
Summary of the invention
In view of this, the utility model is intended to propose a kind of mismatch pipeline in-situ repairing device, and having in-situ immobilization mismatch pipeline does not need excavation, does not affect the advantages such as road traffic above pipeline, quick for installation, the engineering time is short.
For achieving the above object, the technical solution of the utility model is achieved in that
A kind of mismatch pipeline in-situ repairing device, comprise a rubber seal, a pair stainless steel expansion loop and two cover stainless steel combined pad, described rubber seal is provided with at the inwall of mismatch pipeline, rubber seal can the seepage at isolating pipelines mismatch place, a groove is respectively provided with respectively at the two ends of described rubber seal inwall, described a pair stainless steel expansion loop is arranged in the groove at described rubber seal inwall two ends respectively, the two ends of rubber seal and mismatch inner-walls of duct are adjacent to sealing by stainless steel expansion loop, complete the in-situ immobilization of mismatch pipe leakage, described stainless steel expansion loop is inc ring-type, the two ends of described stainless steel expansion loop opening are the termination being provided with center hole, described two cover stainless steel combined pad lay respectively between two terminations of stainless steel expansion loop, external force can be used for stainless steel expansion loop applying expansion power, reach the effect that rubber seal two ends and inner-walls of duct are adjacent to sealing, stainless steel combined pad and stainless steel expansion loop termination are fixed through stainless steel combined pad and stainless steel expansion loop termination by bolt.
Further, all there is the outer chamfering of 45 degree at the two ends of described rubber seal, the zigzag fashion circumference strain line that outside described rubber seal, two ends also all have 70mm wide, the outer chamfering of rubber seal can prevent the foreign material in pipe drainage to be affiliated on its end face, and its zigzag fashion circumference strain line can make rubber seal increase its sealing effect.
Further, described stainless steel combined pad is made up of the stainless steel cushion block of different-thickness, and described stainless steel cushion block is no less than 2.
Relative to prior art, a kind of mismatch pipeline in-situ repairing device described in the utility model has following advantage: this mismatch pipeline in-situ repairing device can effectively repair mismatch pipeline, reach the antiseepage function of mismatch pipeline, and the advantage that has that pipe-repairing does not need excavation, do not affect road traffic above mismatch pipeline, quick for installation, the engineering time is short etc.
