Description
Technical field
The utility model relates to Concrete Face Rockfill Dam technical field, is a kind of concrete face rockfill dam periphery fissure waterstop structure.
Background technology
For thick backfill, under deadweight and upstream effect of water pressure, can there is moderate finite deformation in rockfill, and periphery fissure also can open, shear and sedimentation Three-direction deformation, and deformation values may reach several tens cm.For thick backfill, periphery fissure establishes three road sealings usually: bottom waterstop, middle part sealing and top sealing.According to domestic and international Concrete Face Rockfill Dam technical development experience, because of middle part waterstop constructional difficulties, construction quality not easily ensures, because the waterstop bottom concrete quality that makes not in place that locally vibrates is bad, except superelevation dam, mostly tend to cancel middle part sealing, the antiseepage reliability of top and bottom waterstop is had higher requirement.When face dam generation seepage, when need repair periphery fissure waterstop, check if cut panel one by one and repair bottom and middle part sealing, engineering quantity is huge and meeting counter plate cause new destruction.Therefore, large deformation can be adapted to according to the thinking exploitation of strengthening top sealing and the periphery fissure top water-stopping structure of good seepage-proof property is one of key technical problem of Concrete Face Rockfill Dam.
Utility model content
What the purpose of this utility model was to provide a kind ofly can adapt to large deformation and the concrete face rockfill dam periphery fissure waterstop structure of good seepage-proof property.
The utility model realizes by following technical scheme:
Concrete face rockfill dam periphery fissure waterstop structure, the seam sealing being included in periphery fissure groove arranges combination rubber bar; Described combination rubber bar is coated with metallic water stop tie; Described metallic water stop tie and described combination rubber bar male-female engagement; Described metallic water stop tie both sides and slot concrete surface bond;
Hide above described metallic water stop tie and have antiseepage protective cover sheet; Plastic filler is filled with between described metallic water stop tie and described antiseepage protective cover sheet;
Described antiseepage protective cover sheet is fixed by expansion bolt and stainless steel press strip.
Described combination rubber bar comprises the secondary rubber bar that the primary elastomeric rod that is placed on middle Φ 50mm and two are placed on the Φ 30mm of both sides.
Described antiseepage protective cover sheet and described stainless steel press strip dual-side are by elasticity edge sealing edge sealing, and described elasticity edge sealing width is no less than 5CM.
Described antiseepage protective cover sheet is ethylene propylene diene rubber cover plate.
Described metallic water stop tie is stainless steel waterstop or red copper waterstop.
The mode that the utility model proposes increases arc closed metal waterstop strengthens top stagnant water effect; surface anti-seepage protective cover sheet and concrete seal and are connected to form surface-closed sealing; curved metal waterstop forms second by cementing agent and concrete binding and closes sealing, and the specific shape of metallic water stop tie can adapt to moderate finite deformation with the acting in conjunction of combination rubber bar.Top water-stopping structure involved by the utility model have adapt to that large deformation, sealing sealing effect are outstanding, construction and the feature such as easy to maintenance, effectively prevent periphery fissure seepage, greatly improve the antiseepage reliability of water-stopping structure, in the newly-built concrete face rockfill dam engineering that can be widely used in 100m level and reinforcement and repair engineering.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, but this embodiment should not be construed restriction of the present utility model, only for example, simultaneously by illustrating that advantage of the present utility model will become clearly and easy understand.
As shown in drawings, concrete face rockfill dam periphery fissure waterstop structure, the seam sealing being included in periphery fissure groove 1 arranges combination rubber bar 3; Combination rubber bar 3 is coated with metallic water stop tie 4; Metallic water stop tie 4 and combination rubber bar 3 male-female engagement; Metallic water stop tie 4 both sides and slot concrete surface 2 bond; Adhesion strength and shear strength are greater than 2.5Mpa
Hide above metallic water stop tie 4 and have antiseepage protective cover sheet 6; Plastic filler 5 is filled with between metallic water stop tie 4 and antiseepage protective cover sheet 6; Plastic filler 5 adaptive deformation ability is strong, and can play periphery fissure and close and antiseepage effect, its upper surface antiseepage protective cover sheet 6 is close to above the bulge of plastic filler 5 formation, and both sides are connected on the concrete of periphery fissure both sides by stainless steel press strip 8 and expansion bolt 7.
Combination rubber bar 3 comprises the secondary rubber bar 32 that the primary elastomeric rod 31 that is placed on middle Φ 50mm and two are placed on the Φ 30mm of both sides.Combination rubber bar 3 provides support for metallic water stop tie 4, and when periphery fissure opens comparatively large, primary elastomeric rod 31 can fall to embedding periphery fissure, plays certain sealing effect.
Antiseepage protective cover sheet 6 and stainless steel press strip 8 dual-side are by elasticity edge sealing 9 edge sealing, and elasticity edge sealing 9 width is no less than 5CM.
Antiseepage protective cover sheet 6 is ethylene propylene diene rubber cover plate.
Metallic water stop tie 4 is stainless steel waterstop or red copper waterstop.
It should be noted that: to those of ordinary skill in the art, can also make some changes or distortion to the utility model under the prerequisite not changing the utility model principle, this belongs to protection domain of the present utility model equally.
