For solving the problems of the technologies described above adopted technical scheme be: a kind of checkdam for hydroelectric project coombe or river course, comprise by rock ballast stockpile and build the checkdam matrix forming, described checkdam matrix is projected as trapezium structure in its cross section, on the upstream face slope of the described checkdam matrix of trapezium structure from outer toward interior fixed bed and the domatic anti-leakage layer of being furnished with successively.
Further, described domatic anti-leakage layer is the sloping core geomembrane being covered on the described checkdam matrix upstream face slope of trapezium structure, and described fixed bed is to cover the solid bank protection layer in described sloping core geomembrane outside.
Further, described checkdam also comprises padding layer, and described padding layer is arranged on the slope of checkdam matrix upstream face of described domatic anti-leakage layer inner side.
Further, described checkdam also comprises the anti-filter transition bed of material, and the described anti-filter transition bed of material is arranged on the slope of checkdam matrix upstream face of described padding layer inner side.
Be further, described checkdam matrix heap is built on the covering layer in described hydroelectric project coombe or river course, between described covering layer and described checkdam matrix, be furnished with the bottom anti-leakage layer being made up of horizontal geomembrane, described bottom anti-leakage layer and described domatic anti-leakage layer are tightly connected at bottom, the upstream face slope place of the described checkdam matrix of trapezium structure.
Further, described being tightly connected as being welded to connect.
Further, between described bottom anti-leakage layer and described covering layer, be also provided with bottom padding layer.
Further, between described bottom anti-leakage layer and described checkdam matrix, be also provided with top padding layer.
Further, be also provided with in the lateral middle of described checkdam matrix the inner bag anti-leakage structure that vertically upwards stretch on edge, described inner bag anti-leakage structure is longitudinally along stretching the two ends that cause described checkdam matrix.
Further, described inner bag anti-leakage structure is upwards made up of along the vertical geomembrane of stretching indention.
The beneficial effects of the utility model are: because the checkdam matrix that forms described checkdam is built and formed by rock ballast stockpile, then built from rock ballast stockpile on the described checkdam matrix upstream face slope forming from outer toward interior fixed bed and the domatic anti-leakage layer of being furnished with successively.Thereby effectively simplify the structure of described checkdam, and then simplify working procedure, shorten the construction period, reduce cost of production, simultaneously, because described fixed bed and domatic anti-leakage layer are arranged on the upstream face slope of described checkdam matrix, can also effectively extend described checkdam dam body seepage paths, reduce downstream infiltration capacity, improve osmotic stability.
