Compared with prior art, the utility model has the following beneficial effects:
1. this kind passes through the water expandable waterstop of setting for the surface watertight seal structure of concrete face rockfill dam, avoid
Water seepage prevention cover board is bonded gap that is not tight and generating with concrete slab, improves the antiseepage energy of surface watertight seal structure
Power reduces the working procedure of edge sealing processing, shortens the construction period；
2. improving the connection that sealing cover board and water expandable waterstop are pasted by the water-swellable water-stop glue of setting
Degree, while enhancing integral strength；
3. the contact area between structure glue and waterstop is increased by the pawl being arranged on rubber water-proof band, and
The confined space that pawl and concrete surface are surrounded can control the trickling of During Initial Stage Construction high polymer structure glue, effectively avoid
The loss of structure glue ensure that effective connection of waterstop and concrete slab；
The polygon bulge-structure being arranged on the downside of 4.PVC stick, can effective fixing PVC stick position so that in water pressure
Concrete slab seam gap can be preferably bonded by acting on lower PVC stick, improve whole water seepage prevention ability.
The design of the utility model total is rationally ingenious, and structure is simple, and structure stress is clear, and saves site operation
Process, construction quality are easier to be protected.
