Abstract
The utility model discloses a seam water stopping structure, relating to a water stopping structure and comprising a rubber rod, an arc metal belt, a corrugated rubber water stopping belt and a GB flexible filler, wherein the rubber rod is arranged on a seam port of a seam V-shaped groove, the arc metal belt for pressing the rubber rod is arranged above the rubber rod, the corrugated rubber water stopping belt is covered above the arc metal belt, and the GB flexible filler is filled between the corrugated rubber water stopping belt and the rubber rod. The seam water stopping structure is suitable for a high dam with the height of above 100m.
Description
Technical field
The utility model relates to a kind of water-stopping structure.
Background technology
For high rock, joint seal at home and abroad all is a difficult problem.In the face dam of present design and running, what the seam on most of dams adopted is the three road water-stopping structure forms that proposed by Brazilian A Liya face dam, except that base copper sealing and middle part waterstop, also is provided with IGAS plastic filler surface watertight seal at the sealing of seam.Aspect sealing mechanism, this surface watertight seal form belongs to become silted up fills out type, and it is to make sealing material under the effect of water pressure, open seam is become silted up fill out, to reach the purpose of sealing.Yet, show that through experiment in 100m higher level high dam, the stagnant water effect of base copper sealing and middle part waterstop all causes anxiety.Therefore for the high face dam more than the 100m, except the seal plate to the bottom at existing middle part carries out the adjustment of material improvement and method for designing, the emphasis of whole sealing is the improvement to surperficial sealing.
The utility model content
The purpose of the utility model is: propose a kind of joint seal structure that can be applicable to the high face dam that 100m is above.
The purpose of the utility model realizes through following technical proposals:
A kind of joint seal structure; Form by rubber bar, curved metal band, ripple type rubber fastening band and GB flexible filler; Seam sealing at seam " V " type groove is provided with said rubber bar; Said rubber bar top is provided with the said curved metal band that compresses said rubber bar, and said curved metal band top hides has said ripple type rubber fastening band, is filled with said GB flexible filler between said ripple type rubber fastening band and the said rubber bar.
As optimal way, said rubber bar is φ 120-180mm.
As optimal way, said ripple type rubber fastening band is fixed with zinc-plated band iron and expansion bolt.
As optimal way, said curved metal band is fixed with zinc-plated band iron and expansion bolt.
As optimal way, said curved metal band is that stainless steel or aluminium alloys are processed.
The beneficial effect of the utility model: rubber bar provides support whole surperficial sealing on the one hand, will be reduced to minimum level by the slit that seam is opened generation on the other hand; The curved metal band compresses rubber bar and seam, further guarantees and the plugging effect of Reinforced Rubber rod butt joint and the persistence of effect; Waterstop further guarantees the sealing of seam; The filler butt joint becomes silted up and fills out.Reach the surface of good stagnant water effect through four layers of protection.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing the utility model is further described.
As shown in Figure 1; A kind of joint seal structure; Be made up of rubber bar 1, curved metal band 2, ripple type rubber fastening band 3 and GB flexible filler 4, be provided with said rubber bar 1 at the seam sealing 5 of seam " V " type groove, said rubber bar 1 top is provided with the said curved metal band 2 that compresses said rubber bar 1; Said curved metal band 2 tops hide has said ripple type rubber fastening band 3, is filled with said GB flexible filler 4 between said ripple type rubber fastening band 3 and the said rubber bar 1.As optimal way; Shown in present embodiment; Said rubber bar 1 is φ 120-180mm; The zinc-plated band iron 5 of said ripple type rubber fastening band 3 usefulness is fixing with expansion bolt 6, and the zinc-plated band iron 5 of said curved metal band 2 usefulness is fixing with expansion bolt 6, and said curved metal 2 bands are processed for stainless steel or aluminium alloys.
The rubber bar 1 of the utility model provides support whole surperficial sealing on the one hand, will be reduced to minimum level by the slit that seam is opened generation on the other hand; Curved metal band 2 compresses rubber bar 1 and seam sealing 5, further guarantees and the plugging effect of Reinforced Rubber rod 1 butt joint sealing 5 and the persistence of effect; Ripple type rubber fastening band 3 further guarantees the sealing of seam; Filler 5 butt joints become silted up and fill out.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
Claims (5)
1. joint seal structure; It is characterized in that: form by rubber bar, curved metal band, ripple type rubber fastening band and GB flexible filler; Seam sealing at seam " V " type groove is provided with said rubber bar; Said rubber bar top is provided with the said curved metal band that compresses said rubber bar, and said curved metal band top hides has said ripple type rubber fastening band, is filled with said GB flexible filler between said ripple type rubber fastening band and the said rubber bar.
