Technical field
Concrete surface dam enrockment technical field is the utility model is related to, is more specifically that a kind of concrete slab squeezes
Crush bad reparation structure.
Background technology
Concrete face rockfill dam extruding destruction is the Ba Lage of high CFRD runs into recent years outstanding problem, such as 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 during destroying development downwards for the extruding of high dam vertical lap seam with level to extruding.Extruding destruction causes panel
Surface concrete is peeled off, Copper water stop deformation increases, and is extruded to destroy and often occurred, in eulittoral zone, to have a strong impact on dam durability
With longtime running safety.Occurred according to domestic and international part panels rock-fill dams after extruding destroys it can be seen from the change of leakage, extruding is broken
One of the main reason for being badly face dam seepage, such as leakage of the Brazilian Kan Bosinuo Butterworths face dam after extruding occurs and destroys
More than 40 times before being.
For face slab rupture, conventional treatment mode is to be poured again by former design requirement after cutting damaged concrete at present
Build concrete slab.But still unstabilized face dam is particularly settled for dam deformation, the feelings for extruding destruction repeatedly often occurs
Condition, after extruding destruction reparation such as Tianshengqiao-I vertical lap seam, destroyed again repairing in area.

Coagulate and antiseepage cover plate is provided with native panel, the both sides of described antiseepage cover plate are fixed on concrete by expansion bolt and steel press strip
On panel.
In the above-mentioned technical solutions：Interfacial agents are coated between described patching material and the concrete slab cut.
In the above-mentioned technical solutions：Antiseepage cover plate bottom is painted between described antiseepage cover plate and described patching material
Glue.
In the above-mentioned technical solutions：The depth that cuts of concrete slab destruction area above described vertical lap seam should not
Less than 5 centimetres；The width of described rubber slab and described height of dam and damaged degree matching degree, the transverse width of described rubber slab
For 2.5-5 centimetres, depth is 15 centimetres.
In the above-mentioned technical solutions：The top width of described V-groove is 10 centimetres, and depth is 5 centimetres.
The utility model has the following advantages that：1st, to former vertical lap seam middle and upper part staking and by way of filling rubber slab,
The crimp after water storage again is absorbed, the water sealing structure of closing is set above vertical lap seam after repair, can thoroughly solve face
Plate extruding is destroyed to caused by concrete slab and leakage problems.2nd, the utility model proposes suitable to waterborne and disposal under water
With material and Specific construction technique, there is larger application value.
