Description
Technical field
The utility model relates to a kind of antidetonation water-stopping structure of CFRD.Be applicable to earthquake zone rock dam body joint designs.
Background technology
The seam of rock is the weak link of dam body quality often.When earthquake takes place when, the destruction that distortion between the panel or dislocation possibly cause joint seal, how the slab joint water-stopping structure adapts to the shock resistance requirement, is the problem that often runs in the engineering practice.
How to make the panel water-stopping structure have stronger deformation performance to adapt to the earthquake operating mode through certain measure; The situation of avoiding the vertical lap seam two sides board concrete at riverbed middle part to be extruded destruction simultaneously takes place; Clamp-on through hydraulic action under the prerequisite in seam chamber at assurance surface flexible sealing; Suitably reducing the V-shaped groove size, thereby avoid the reduction of counter plate section area, is an important technology in the CFRD design.
Summary of the invention
The technical problem that the utility model will solve is: to the problem of above-mentioned existence; A kind of antidetonation water-stopping structure of simple in structure, CFRD that construction cost is low is provided; Improve the antidetonation sealing ability of structure, the situation of avoiding the vertical lap seam two sides board concrete at middle part, riverbed to be extruded destruction takes place.
The technical scheme that the utility model adopted is: the antidetonation water-stopping structure of CFRD; Has panel; It is characterized in that: in the seam of adjacent two panels, fill sealing part, the bottom of sealing part is copper seal, neoprene gasket and cement mortar successively; The panel on sealing part top is provided with V-shaped groove, and trench bottom is filled the neoprene rod, and the V-shaped groove surface is half elliptic flexible filler, and the flexible filler outside coats antiseepage protection cover plate, and the protection cover plate is fixed through fastening devices and panel.
Said sealing part is impregnate with bitumen deal board (a pressure property seam), said V-shaped groove groove depth 0 ~ 5cm.
Said sealing part is asphalt emulsion (opening a property seam), said V-shaped groove groove depth 10cm, width 10cm.
Said fastening devices comprises band steel and expansion bolt, and band steel is pushed down antiseepage protection cover plate and applied HK elasticity edge sealing agent in the band steel outside.
The beneficial effect of the utility model is:
1, for the pressure property seam at middle part, riverbed, in seam, clog the thick impregnate with bitumen deal board of 12mm, seam both sides concrete is extruded the situation of destruction in the time of can avoiding earthquake to take place;
2, comparatively speaking, the risk of both sides squeeze and destroy when there is earthquake in pressure property seam panel, so its globality outbalance.(open property seam V-shaped groove degree of depth 10cm, the pressure property seam degree of depth can be reduced to 0 ~ 5cm), bottom copper seal nose height is got standard lower limit 4cm, can reduce the reduction of counter plate section area to greatest extent suitably to reduce joint seal V-shaped groove size;
3, because the flexible filler of pressure property seam V-shaped groove is clamp-oned in the process of seam chamber, play the effect of drainage under hydraulic action, therefore reduce the V-shaped groove size (like dark 10cm with routine; Wide 10cm makes dark 5cm into; Wide 10cm) can bring certain influence to drainage, but can make the bulge shape of joint seal into semiellipse size (major axis is consistent with the seam direction) by the semicircle size of routine, make more filler more near joint centerline; Thereby strengthen clamp-oning effect, to reduce this influence;
4, engineering practice shows, compares with the angle steel that adopts in the past, and band steel can better adapt to seismic wave, and is also better relatively to the closure of flexible filler simultaneously;
5, to improve the compliance to seismic wave, anchoring effect can be strengthened in particularly northern freeze thawing area to the mode of expansion bolt employing mechanical anchor combination chemical anchoring (HK anchoring agent) as sealing facial mask anchorage element; Sealing measure (HK elasticity edge sealing agent edge sealing is used in the band steel outside) is taked at butt joint sealing edge, to strengthen the sealing reliability.
