Description

Pipeline rehabilitation device

Technical field

The utility model relates to a kind of reparation field, especially a kind of pipeline rehabilitation device of quick pipe-repairing breach.

Background technique

Be used for carrying the pipeline of the liquid such as water, in order to ensure the Security of carrying, pipeline needs to remain intact in course of conveying, and tube wall can not exist crack, otherwise easily occurs the phenomenon of seepage.

But pipeline in use, if be subject to jamming on of weight, or impact, or exterior temperature change is large, still can cause pipeline breaking, cause and leak.Just need when seepage appears in pipeline to repair pipeline.

Some pipeline can be closed completely and be carried out integral replacing reparation, but some pipeline is little crack, and close carry out entirety reparation completely, cost is high, and the time is long, also needs throttle down, and block the flowing water in pipeline, engineering work load is larger.Some operating space, position is smaller, and integral replacing is repaired cumbersome, can damage the firmware of surrounding, such as wall etc.Therefore one is needed to flow without the need to blocking in pipeline, simultaneously less to the requirement of operating space obturator.

People also devise some new pipeline rehabilitation devices, adopt a kind of mode of jacket, seal between cover two ends and pipeline outer wall, but Existential Space between the cover inwall of this pipeline rehabilitation device and pipeline outer wall, liquid in pipeline goes out to leak in this space from crack, the emphasis repaired just transfers to the sealing position at two ends, the pressure of the liquid especially in pipeline is all applied to the sealing position at two ends, high to the seal request at two ends, and easily there is distortion after logical pressure in pipeline, sealing between obturator and pipeline outer wall can decline because of pipe deforming, secondary seepage may be there is.

Summary of the invention

The utility model solves existing integral replacing reparation needs to block stream in pipeline, also need the defect of larger operating space simultaneously, a kind of pipeline rehabilitation device is provided, adopt coated and the mode of holding pipeline tightly seals pipe crack, flow without the need to blocking in pipeline, little to the requirement of operating space.

The utility model also solves the mode that existing pipeline uses sleeve pipe parcel, two ends seal and repairs, pressure is made to transfer to sealing position, easily in the defect of sealing position secondary seepage, a kind of pipeline rehabilitation device is provided, adopt coated and the mode of holding pipeline tightly seals pipe crack, anti-sealing goes out to ooze out from crack, and the mode of extruding can prevent the crack of pipeline from again expanding.

The utility model solves the technological scheme that its technical problem adopts: a kind of pipeline rehabilitation device, comprise reparation body, repairing body is divided into two-layer, be respectively outer and internal layer, its ectomesoderm is bent clad, and internal layer is flexible sealing layer, and outer and internal layer is composited, time coated, repair body and be out of shape with pipeline profile; Outer field dual-side is provided with some attachment holes, and attachment hole is provided with coating member, and coating member bypass pipeline outer wall combines coated with reparation body and holds pipeline tightly.Skin is masterpiece appliance, and internal layer is Sealing, and during reparation, internal layer and pipeline outer wall fit, and coating member bypass pipeline holds pipeline tightly, flow without the need to blocking in pipeline, little to the requirement of operating space; Internal layer is directly covered in the crack place of pipeline, and anti-sealing goes out to ooze out from crack, and coating member is held pipeline tightly and produced extruding to pipeline outer wall, and the crack of pipeline is shunk, and can not continue to expand because of manifold pressure; Outer bent expression is repaired body and can be changed with pipeline profile, namely repairs the pipeline that this physical efficiency adapts to various outer diameter.

As preferably, the internal layer repairing body is attached to outer field whole surface.

As preferably, it is plane for repairing body; Or repair the curved shape of body.

As preferably, it be plane for repairing body, and internal layer is thick structure such as grade; Or repair the curved shape of body, internal layer is thick middle, the structure that both sides are thin.

As preferably, the internal surface repairing body internal layer is recess and protuberance concaveconvex structure separately, and protuberance is rib-like, it is recess between protuberance, the surface of rib is in same plane or same cambered surface, and the periphery of internal layer is protuberance, and the protuberance of periphery connects into a closed annular.After the surface of the internal layer of concaveconvex structure and pipeline outer wall are fitted, the effect of sealing is better.

As preferably, the width of the protuberance of periphery is maximum, and the width of inner protuberance is little, and the width of inner protuberance is all equal.

As preferably, coating member is fixed block, and the corresponding fixed block repairing the same circumference of body is two, and two fixed blocks are connected to be repaired on the attachment hole of body both sides, and fixed block adopts the mode to eye-splice is closed to fix, or adopts the sealed mode of bolt to fix.

As preferably, fixed block comprises fixed block body, and one end of fixed block body is connecting ring, and connecting ring is connected with attachment hole; To in two fixed blocks inserted, one end of a fixed block is buckle, and the correspondence surface of the fixed body of another fixed block is provided with latch.

As preferably, the outside left repairing the corresponding attachment hole of skin of body is cylinder.

As preferably, during reparation, two to repair body relative duct size involutory coated, and two attachment holes repairing bodies stagger mutually, and a coating member repaired on body is walked around another and repaired body.Two repair the involutory Clad pipe of body, expand the surface of contact with pipeline, make pipe extrusion stressed more even.

The beneficial effects of the utility model are: during reparation, and internal layer and pipeline outer wall fit, and coating member bypass pipeline holds pipeline tightly, flow without the need to blocking in pipeline, little to the requirement of operating space; Internal layer is directly covered in the crack place of pipeline, and anti-sealing goes out to ooze out from crack, and coating member is held pipeline tightly and produced extruding to pipeline outer wall, and the crack of pipeline is shunk, and can not continue to expand because of manifold pressure.
