Therefore, an urgent need exists for providing a waterproof device used in the splicing seam of the final prefabricated pipe gallery, which has a simple structure and a good waterproof effect.
SUMMERY OF THE UTILITY MODEL
To the above problem, an object of the utility model is to provide a be used for waterproof device in prefabricated piping lane piece of minor details, the utility model discloses a technical scheme as follows:
a waterproof device used in splicing joints of a final-section prefabricated pipe gallery is used for being connected between the final-section prefabricated pipe gallery and a pouring section and performing waterproof sealing; the waterproof device used in the splicing joint of the last-section prefabricated pipe gallery comprises a V-shaped telescopic waterproof ring, an expansion waterproof rubber strip arranged between the last-section prefabricated pipe gallery and the pouring section, a first L-shaped crimping end and a second L-shaped crimping end which are integrally formed with the telescopic waterproof ring, arranged at two ends of the telescopic waterproof ring and in L shapes, a first connecting part which is crimped on the first L-shaped crimping end and used for crimping the first L-shaped crimping end on the last-section prefabricated pipe gallery, and a second connecting part which is crimped on the second L-shaped crimping end and used for crimping the second L-shaped crimping end on the pouring section and has the same structure as the first connecting part;
first connecting portion including the laminating stagnant water pad on the lateral wall of prefabricated piping lane of end section, the laminating is served in first L crimping, and is the clamp plate of L shape to and run through clamp plate, first L crimping end and stagnant water pad setting in proper order from the right side to a left side and place in stock in the prefabricated piping lane of end section.
Preferably, the anchor of the second connecting portion is L-shaped.
Compared with the prior art, the utility model discloses following beneficial effect has:
the expansion waterproof rubber strip is arranged between the tail prefabricated pipe gallery and the pouring section to provide a moving space for the change of the distance, so that the expansion waterproof rubber strip in the embodiment can be used for waterproofing and can also provide the pouring distance; additionally, the utility model discloses ingenious flexible waterproof ring to adopt clamp plate, stock and stagnant water pad to connect, can guarantee that the prefabricated piping lane of minor part festival and the cast-in-place change flexible connection who builds the end, can also solve traditional expansion joint strip and cause the problem of leaking because of prefabricated piping lane festival and the cast-in-place interval change of building between. To sum up, the utility model has the advantages of simple structure, sealed reliable, telescopic connection have very high practical value and spreading value in prefabricated piping lane connection technical field.
