Description
Technical field
It is more specifically that a kind of concrete slab extruding is broken the present invention relates to concrete surface dam enrockment technical field
It is bad to repair structure and construction method.
Background technology
Concrete face rockfill dam extruding destruction is the outstanding problem that high CFRD runs into recent years, such as Ba Lage of Brazil
Lactel face dam and Kan Bosinuo Butterworths face dam, the Tianshengqiao-I of not Harry face dam of Lesotho and China, three plates
The face dams such as small stream, cloth west.Extruding destruction mostly occurs in pressure property vertical lap seam, develops downwards from dam crest, into dam or 1/3 height of dam stops；
Often destroyed to extruding with level during for high dam vertical lap seam extruding destruction development downwards.Extruding destruction causes panel
Surface concrete is peeled off, Copper water stop deformation is increased, and extruding destruction often occurs in eulittoral zone, has a strong impact on dam durability
With longtime running safety.It can be seen from the change of leakage after domestic and international part panels rock-fill dams occur extruding destruction, extruding is broken
Bad is the one of the main reasons of face dam seepage, such as leakage of Brazil's Kan Bosinuo Butterworths face dam after it there is extruding destruction
More than 40 times before being.
For face slab rupture, current conventional treatment mode is to be poured again by former design requirement after cutting damaged concrete
Build concrete slab.But still unstabilized face dam is particularly settled for dam deformation, the feelings for extruding destruction repeatedly often occurs
After the extruding destruction of condition, such as Tianshengqiao-I vertical lap seam is repaired, destroyed again in area repairing.
