Description
Technical field
Stop water guide field, more particularly to a kind of tunnel aseismatic joint water guide formula the invention belongs to yielding regional tunnel aseismatic joint
Waterstop.
Background technology
Waterstop is one of sealing material that concrete seam is generally used in tunnel construction, mixed installed in tunnel double-lining
In the middle of solidifying soil, the thin tail sheep deformation of movement joint is adapted to without losing water stopping function.The reason for causing waterstop to fail at present,
One is that waterstop deformation is excessive, i.e. the displacement of movement joint has exceeded the deformation displacement of waterstop, and waterstop is drawn into bad；Two be with both
There is waterstop not possess good drain function, be easily caused and bear larger effect of water pressure, cause waterstop autoclasia or stop
Water band and tunnel lining concrete separation failure, cause waterstop to fail.
Current waterstop can bear the stretcher strain of below 3cm due to reasons in structure, when deformation is when big, waterstop
Deformed area rubber will be stretched thinning, while pulling force can be passed into anchorage zone rubber with deformed area, make anchorage zone rubber same
When tension-thining, make to produce gap between waterstop and concrete, the water of tunnel internal can bypass waterstop, tunnel along this gap
There is drainage, this is also one of the reason for waterstop fails.And existing drainage type waterstop, it is by waterstop deformed area
U-type groove is designed to, a gap of about 4mm wide is left in U-type groove, the presence in this gap can fall into the debris of tunnel internal
It is particularly evident when waterstop occurs stretcher strain inside water stop U type groove, after debris fall into U-type groove inside, when waterstop hair
During raw compression, debris can break waterstop, waterstop is lost sealing effect.
In earthquake intensity area high, due to earthquake reason, cause geology soft, because length of tunnel is very long, by this
The tunnel in area will have very big deformation., it is necessary to a plurality of width of segment design is up to 10cm's in tunnel total length during Tunnel Design
Aseismatic joint, causes the deformation in tunnel to be distributed in each aseismatic joint earthquake, for adapting to the deformation that earthquake is caused.Due to antidetonation
Seam width reaches 10cm, and existing waterstop is no longer applicable.
The content of the invention
The embodiment provides a kind of tunnel aseismatic joint water guide formula waterstop, be a kind of deflection up to 10cm without
Lose the product of water stopping function, according to aseismatic joint it is relatively wide the characteristics of, aseismatic joint water guide formula waterstop in tunnel also has prevents miscellaneous
Thing enters waterstop deformed area and water guide structure.
To achieve these goals, this invention takes following technical scheme：
A kind of tunnel aseismatic joint water guide formula waterstop, it is characterised in that including anchoring section, deformation groove, deformation groove protective layer,
Earthquake protection groove, diversion seam；Wherein：
The anchoring section is located at the two ends of waterstop, for waterstop to be fixedly connected with tunnel-liner, the deformation groove
The middle part deformed area of waterstop is built up in, waterstop is realized stretching or deformed by the deformation groove；The deformation groove protective layer
Positioned at the top of the deformation groove；The earthquake protection groove is arranged at the deformation groove protective layer centre position；The diversion seam
It is arranged in the earthquake protection groove.
The deformation groove is dovetail groove or V-groove.
When waterstop bears the small deformations such as temperature deformation, the differential settlement of tunnel-liner, the earthquake protection groove is not
It is broken, deforms with the deformation groove.
When waterstop bears the seismic deformation in tunnel, the earthquake protection groove is taken the lead in being broken by geological process power.
The diversion seam is intermittently-arranged along the length direction of the earthquake protection groove, and the diversion seam is through the whole change
Shape groove protective layer, tunnel periphery water is stitched by the diversion and flowed into the deformation groove, and the deformation groove is derived as guiding gutter
Water in groove.
The ragged edge size of the deformation groove is consistent with tunnel-liner aseismatic joint width dimensions.
The thickness setting number range of the deformation groove protective layer, the depth of the earthquake protection groove is the deformation groove guarantor
The 2/3 of covering thickness.
The diversion seam is to arrange 200mm every 1000mm along the intermittently-arranged size of earthquake protection groove.
The diversion seam seam is wide to be not more than 1mm.
The anchoring section is buried in being or back sticking type.
The technical scheme provided by embodiments of the invention described above can be seen that present invention reduces deformation groove protective layer pair
The effect of pullling at other positions of waterstop, preferably protects the water-stagnating effect of waterstop.Waterstop is make use of to greatest extent
Deformation groove, improve Water stop structure utilization rate.
The additional aspect of the present invention and advantage will be set forth in part in the description, and these will become from the following description
Obtain substantially, or recognized by practice of the invention.
