Description
Technical Field
The utility model belongs to the technical field of the municipal administration pipeline, concretely relates to circular pipeline repair structure.
Background
The underground drainage pipeline is an essential infrastructure of modern cities, and is the most important facility for urban water pollution control, urban sewage discharge, waterlogging drainage and flood control. As the drainage pipeline is buried underground for a long time, the pipeline wall can crack or be damaged, and the like, so that the sewage seeps out to cause secondary pollution to the nearby soil. At present, the sewer pipe of most cities in China is buried again after excavation or hoops are added on the outer pipe wall of the pipeline for plugging after excavation, and because underground drainage pipelines of cities are generally huge, the buried pipe after excavation needs to consume great manpower, material resources and financial resources; the latter also needs to excavate and expend manpower and materials, in addition from the mode of carrying out the shutoff outside the pipeline, the intraductal rivers can continue to erode pipeline damage/fracture department, makes damage/fracture bigger and bigger, and when intraductal rivers had very big pressure, rivers can break through the outside shutoff part of pipeline, greatly reduced the shutoff effect.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a circular duct repairs structure carries out the shutoff to damaged/fracture department from circular duct is inside, and the effectual intraductal rivers that have avoided erode the damaged/fracture department of pipeline, utilizes the pressure of intraductal rivers simultaneously, extrudees the shutoff inside lining on the inside pipe wall, has improved the shutoff effect.
In order to realize the technical purpose, the utility model discloses a following technical scheme: a circular pipeline repairing structure comprises a tubular plugging lining for plugging a damaged position of a pipeline, wherein the plugging lining is arranged in a pipe cavity of the pipeline, and the surface of the plugging lining is attached to the inner wall of the pipeline; the pipeline plugging device further comprises rubber sleeves which are located at two ends of the plugging lining and tightly attached to the inner wall of the pipeline, and one side face of each rubber sleeve is tightly abutted to the end face of the plugging lining.
Among the above-mentioned technical scheme, set up pipy shutoff inside lining in the lumen of pipeline and the laminating of face and pipeline inner wall, effectually avoided intraductal rivers to erode pipeline damage/fracture department, utilize the pressure of intraductal rivers simultaneously, extrude the shutoff inside lining on the inside pipe wall, be equipped with the rubber sleeve at the both ends of shutoff inside lining in addition, the rubber sleeve carries out the shutoff and seals the gap that produces between shutoff inside lining and the pipeline inner wall, has further guaranteed the shutoff effect of this structure.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
A round pipeline repairing structure comprises a tubular plugging lining 10 used for plugging a damaged position of a pipeline, wherein the plugging lining 10 is arranged in a pipe cavity of the pipeline, and the surface of the plugging lining is attached to the inner wall of the pipeline; the pipe plugging lining structure further comprises rubber sleeves 20 which are located at two ends of the plugging lining 10 and tightly attached to the inner wall of the pipe, and one side face of each rubber sleeve 20 is tightly abutted to the end face of the plugging lining 10. The tubular plugging lining 10 is arranged in a pipe cavity of a pipeline, the plate surface of the tubular plugging lining 10 is attached to the inner wall of the pipeline, on one hand, the tubular plugging lining 10 is attached to the inner wall of the circular pipeline to plug the damaged/cracked part, on the other hand, the tubular plugging lining 10 supports the tubular plugging lining, so that the plate surface is attached to the inner wall of the pipeline as much as possible, the continuous scouring of the water flow in the pipeline to the damaged/cracked part of the pipeline is effectively avoided, and meanwhile, the pressure of the water flow in the pipeline is utilized to extrude the plugging lining 10 onto the inner. In addition, because the plugging lining 10 is made of rigid materials such as stainless steel and the like, a certain gap can exist between the plugging lining 10 and the inner wall of the pipeline when the plugging lining is attached to the inner wall of the pipeline, the rubber sleeve 20 is arranged at the edge of the plate of the plugging lining 10, the gap between the plugging lining 10 and the inner wall of the pipeline is plugged and sealed by the rubber sleeve 20, and the repairing and plugging effect of the structure is further ensured.
Because this device is applied to circular pipeline, in order to make shutoff inside lining 10 and rubber sleeve 20 better with the laminating of pipeline inner wall, rubber sleeve 20 is the annular. In order to ensure that the rubber sleeve 20 completely seals and seals the plate edge of the sealing liner 10, the rubber sleeve 20 is also provided in a ring shape matching with the sealing liner 10, and the rubber sleeve 20 tightly abuts against the inner wall of the pipeline by virtue of its own elasticity.
Further, the rubber sleeve 20 comprises a baffle 21 and a pressing plate 22, the cross section of the rubber sleeve 20 is in an L shape, an inner ring surface 221 of the pressing plate 22 is tightly attached to the inner wall of the plugging lining 10, the baffle 21 comprises an inner side surface 211 with a plate surface parallel to the plate edge of the plugging lining 10 and an outer ring surface 212 with a plate surface matched with the inner wall of the pipeline, the inner side surface 211 of the baffle 21 is tightly abutted to the plate edge of the plugging lining 10, and the outer ring surface 212 is tightly attached to the inner wall of the pipeline. After the structure is installed, the inner ring surface 221 of the pressing plate 22 is tightly attached to the inner wall of the plugging lining 10, and the plugging lining 10 is extruded on the inner wall of the pipeline.
In order to further ensure the tight adhesion between the rubber sleeve 20 and the inner wall of the pipeline and to ensure that the rubber sleeve 20 after installation does not deviate in the pipeline, the baffle 21 is provided with a through hole 23 with a hole core perpendicular to the surface of the pipeline, the through hole 23 is a counter bore, the rubber sleeve 20 is firmly screwed on the pipe wall by using the socket head cap screw 30 during installation, the socket head cap screw 30 is completely positioned in the through hole 23, and the flushing of the socket head cap screw 30 by water flow in the pipeline is effectively reduced.
