Abstract
It the utility model is related to a kind of combined big strain water proof rubber band, including outer shroud waterstop and inner ring waterstop, described outer shroud waterstop includes functional section and the horizontal segment of functional section both sides, the functional section section of outer shroud waterstop is " Ω " shape structure, described inner ring waterstop includes functional section and the horizontal segment of functional section both sides, and the functional section section of inner ring waterstop is " W " shape structure；Bolt hole is correspondingly offered on the horizontal segment of outer shroud waterstop and inner ring the waterstop both sides.It is of the present utility model it is reasonable in design, process operability is strong, when tunnel main body（Underground engineering）Upper lower burrs occur when the changing of the relative positions and displacement cause product large deformation the outer shroud waterstop of water proof rubber band and inner ring waterstop can abundant strained tensile, will not be destroyed, ensure that water resistance.
Description
Technical field
The utility model belongs to the waterproof sealing technical field of tunnel construction or underground engineering, and in particular to a kind of combined
Big strain water proof rubber band.
Background technology
Rubber waterproof band（Or waterstop）Product has been widely used in engineering construction, China GB18173.2-2014
《High polymer waterproof material Part II waterstop》To original three kinds of rubber fastening bands（Type B, S types, J-type）Advised
Model, according to active fault working condition, original rubber fastening band can not meet requirement, be mainly manifested in rubber water-proof
Section structure deformable amount deficiency with product, in the case where the relative 650mm changing of the relative positions occurs for tomography both sides geology, original rubber
Phenomena such as waterstop can be broken, pull, makes water resistance fail.
The content of the invention
The purpose of this utility model is to provide a kind of combined big strain water proof rubber band, solve tunnel in the prior art or
Rubber fastening band caused by fault of construction and the fault of construction of the underground engineering across the rubber fastening band of ground fissure is broken, pulled
Problem.
In order to solve the above problems, the technical solution of the utility model is：
A kind of combined big strain water proof rubber band, including outer shroud waterstop and inner ring waterstop, described outer shroud sealing
Band includes functional section and the horizontal segment of functional section both sides, and the functional section section of outer shroud waterstop is " Ω " shape structure, described
Inner ring waterstop includes functional section and the horizontal segment of functional section both sides, and the functional section section of inner ring waterstop is " W " shape structure；Institute
State and correspondingly offer bolt hole on outer shroud waterstop and the horizontal segment of inner ring waterstop both sides.
The horizontal segment upper surface of the inner ring waterstop is provided with a plurality of rib, the horizontal segment lower end of the outer shroud waterstop
Face is provided with a plurality of rib, and inner ring waterstop is staggered with the rib on outer shroud waterstop, forms primary and secondary buckle structure.
The material of main part of the outer shroud waterstop and inner ring waterstop is ethylene propylene diene rubber, and inner ring waterstop stops with outer shroud
Rib end face on water band is provided with hydro-expansive rubber layer.
The horizontal segment lower surface of described inner ring waterstop is provided with a plurality of sealing tooth.
Beneficial effects of the present invention：
Compared with prior art, it is of the present utility model it is reasonable in design, process operability is strong, when tunnel main body（Underground
Engineering）The outer shroud waterstop of water proof rubber band and inner ring waterstop are equal when the upper lower burrs generation changing of the relative positions and displacement cause product large deformation
The abundant strained tensile of meeting, will not be destroyed, ensure that water resistance.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is assembling schematic diagram of the present utility model；

The horizontal segment of both sides, the functional section section of outer shroud waterstop 1 include function for " Ω " shape structure, described inner ring waterstop 2
Section and the horizontal segment of functional section both sides, the functional section section of inner ring waterstop 2 is " W " shape structure；The outer shroud waterstop 1 and interior
Bolt hole is correspondingly offered on the horizontal segment of the both sides of ring waterstop 2, referring to Fig. 2, the water of outer shroud waterstop 1 and inner ring waterstop 2
Flat section is bolted on main body and reserves seam both sides, and their functional section annular is bent to be reserved in seam in tunnel main body.
The horizontal segment upper surface of the inner ring waterstop 2 is provided with a plurality of rib 3, the horizontal segment of the outer shroud waterstop 1
Lower surface is provided with a plurality of rib 3, and inner ring waterstop is staggered with the rib 3 on outer shroud waterstop, forms primary and secondary buckle structure.Inner ring
The horizontal segment lower surface of waterstop 2 is provided with a plurality of sealing tooth 5, and sealing tooth 5 plays a part of sealed bottom and anti-skidding fixation.
The material of main part of the outer shroud waterstop 1 and inner ring waterstop 2 is ethylene propylene diene rubber, inner ring waterstop 2 with it is outer
The end face of rib 3 on ring waterstop 1 is provided with hydro-expansive rubber layer 4, and the reliability of waterproof is strengthened.
Content of the present utility model is not limited to cited by embodiment, and those of ordinary skill in the art are new by reading this practicality
Type specification and any equivalent conversion taken technical solutions of the utility model, are claim institute of the present utility model
Cover.
