As an optimal implementation mode of the utility model, the inlay groove has been seted up respectively to the both sides of abaculus, it is square structure to inlay the groove, just the cross-section of abaculus is the I-shaped, the end connection of arc is in inlaying the inslot.
As an optimal implementation mode of the utility model, five recesses have been seted up respectively to the outer wall both sides of rubber circle, and are formed with four sand grips and a salient angle through five recesses, salient angle, sand grip and recess form seal structure, just seal structure is corresponding with the position of mounting groove, the cross-section of salient angle is the triangle-shaped structure.
As a preferred embodiment of the present invention, the cross-section of the convex strip is a trapezoidal structure, the middle portion of the free end of the convex strip is inwardly recessed and both sides of the concave strip are formed with protrusions.
Compared with the prior art, the beneficial effects of the utility model are as follows:
(1) the utility model discloses, including rubber circle and fastening steel ring, paste the rubber circle in the pipeline inner wall, come to support the rubber circle through the fastening steel ring, installation easy operation for the pipeline interface dislocation, the flexible restoration of non-excavation interface of seepage has reasonable in design, and the practicality is strong, and repair quality is high, and the construction is simple and convenient, and the time limit for a project is short, and the construction does not receive ground traffic, characteristics such as influence of environment humiture.
(2) The utility model discloses, utilize the compression equipment to exert pressure to the fastening steel ring, fix purpose-made high strength sealing water stop (rubber circle) installation in the interface both sides to make installation pressure accord with the pipeline operation requirement, thereby establish the permanence in seam crossing, the flexible coupling of leakproofness makes the bearing capacity of pipeline increase substantially, can guarantee pipeline normal operating. Therefore, the repair by adopting the process not only can save a large amount of funds, but also can ensure that the repaired part has the same service life as the pipeline.
