Embodiment
As shown in figure 1, the present embodiment be a kind of ultra-high concrete panel rock-fill dams joint water stop structure, using table, in, bottom
Three roads have the enhanced water sealing structure of independent water stopping function, constitute adaptation seam large deformation and bear the reliable of 300m heads
Seepage prevention system.
The joint seal impervious watertight structure 1 based on SR flexible filler sealing materials, including reality are set in joint surface in this example
Heart rubber bar 11, corrugated rubber band 12 and cloth of reinforcement fibers ethylene propylene diene rubber composite S R antiseepages cover plate protection facial mask 13, wherein
Solid rubber rod 11 is arranged in joint surface V-groove；Corrugated rubber band 12 is covered on solid rubber rod, corrugated rubber band two
While coordinating epoxy resin crab-bolt 14 to be fixed on seam both sides concrete slab 4 through band steel press strip, and sealed with polyureas fluid sealant edge sealing
Antiseepage；Cloth of reinforcement fibers ethylene propylene diene rubber composite S R antiseepages cover plate protection facial mask 13 is covered on corrugated rubber band, its both sides
Coordinate epoxy resin crab-bolt 14 to be fixed on seam both sides concrete slab 4 through band steel press strip, and seal anti-with polyureas fluid sealant edge sealing
Ooze；SR flexible fillers 15 are filled between protection facial mask and corrugated rubber band.Reserved flexible filler joint seal bulge size ensures
Fill up seam and occur cavity of the middle part sealing to joint surface during maximum distortion.
Portion sets waterstop 2 to the present embodiment in the joint, and the waterstop is by collapsible rubber water-proof band body 21 and two pieces
Steel wing side 22 is constituted (see Fig. 2, Fig. 3).Wherein rubber water-proof band body 21 has U-shaped folded slot 212 and is connected to U-shaped folded slot two
The water-proof wing side 213 of lateral edges, water-proof wing side edge is formed with the end bar 214 that blocks water.Rubber water-proof band body is to add in the present embodiment
Muscle rubber, using tensile strength>15MPa water conservancy project rubber is made, its U-type groove section thickness 20mm, water-proof wing side thickness 25mm.
Two pieces of steel wing sides 22 are connected to the both sides of the edge of rubber water-proof band body 21, steel wing edge rubber water-proof respectively in this example
The elongated arrangement of band body, steel wing side is combined into an adult, and steel wing side 22 and rubber fastening band sheet with rubber water-proof band body
Internal reinforcement 211 is connected.Steel wing side 22 is thickness 1.2mm steel plate, and if being stamped and formed out on steel wing side by hydraulic tool
The resistance to plucking hangnail 221 of dry triangle, resistance to plucking hangnail puncture tip is towards rubber water-proof band body side.Resistance to plucking hangnail is in steel in the present embodiment
