In order to solve the above problems, the invention provides anticracking bituminous concrete and the construction party of the anti-seepage connector of clay
Method, the present invention is reasonable in design, is leaked by using anticracking bituminous concrete and clay core, prepares anticracking bituminous concrete first,
Then by storehouse slope or dam slope surface asphalt concrete anti-seepage drop ply, the gradient and storehouse slope or the gradient phase of dam slope of impermeable layer
Together, then in bottom storehouse clay core permeable layers are laid, and with the concrete anti-seepage permeable layers overlap that to have one section overlapping.
More preferably, above-mentioned anticracking bituminous concrete composition is：Water：Cement：Sand：Rubble：Flyash：Swelling agent：Additive：
Polypropylene fibre=150~200：225~250：800~850：1000~1200：70~80：35~40：2.5~2.8, through stirring
Mix mixing solidification and obtain, the ratio of mud of anti-crack concrete is 0.45~0.5.
Above-mentioned additive is efficient retardation water reducing agent.
Above-mentioned rubble includes stone in 10~20mm gravelstones and 20~40mm.
The asphalt concrete seepage prevention drop ply on above-mentioned storehouse slope or dam slope top contains confining bed successively from outside to inside, impervious barrier,
The bituminous concrete room floor of leveling glued layer, storehouse slope or dam slope bottom contains confining bed successively from outside to inside, impervious barrier, strengthens
Internet, antiseepage thickening layer, flatten glued layer.
Above-mentioned confining bed uses antiseepage bituminous concrete, above-mentioned impervious barrier and antiseepage thickening layer to match somebody with somebody pitch coagulation using intensive
Soil, above-mentioned leveling glued layer are made using upgrading with bituminous concrete after rolling, and above-mentioned reinforcing mat network layers use polyester fiber
Or polyvinyl resin fiber.
The above-mentioned and oil surface modified pitch of the asphalt concrete seepage prevention drop ply of clay core drop ply overlap, clay
Anti-leakage layer is more than clay core drop ply in the height away from storehouse slope or dam slope part in the height close to storehouse slope or dam slope.
Above-mentioned contact surface is inclined-plane, or the combinatorial surface that the anti-cambered surface in inclined-plane and plane are formed by connecting.
The length of above-mentioned clay and the overlap of asphalt concrete seepage prevention drop ply is 5~25 meters, the slope of storehouse slope or dam slope
Spend for 0~1：1.5.
Compared with prior art, the present invention at least has technique effect beneficial below, and present invention incorporates clay construction
Low cost and bituminous concrete high barrier property, not only good seepage-proof property, and easy for construction, construction cost is low.And
Clay core drop ply height is higher, can prevent impact and erosion of the bottom storehouse water wave to bottom storehouse and dam bottom.Surface scribbles modified pitch,
