For solving the problems of the technologies described above adopted technical scheme be: a kind of checkdam structure for hydroelectric project coombe or river course, comprise the checkdam matrix built by rock ballast stockpile, described checkdam matrix is projected as trapezium structure in its cross section, and the upstream face slope of the described checkdam matrix of trapezium structure is furnished with fixed bed and domatic anti-leakage layer from outer successively toward interior.
Further, described domatic anti-leakage layer is be covered in the sloping core geomembrane on the described checkdam matrix upstream face slope of trapezium structure, and described fixed bed is cover solid bank protection layer outside described sloping core geomembrane.
Further, described checkdam structure also comprises padding layer, and described padding layer is arranged on the slope of the checkdam matrix upstream face inside described domatic anti-leakage layer.
Further, described checkdam structure also comprises the anti-filter transition bed of material, and the described anti-filter transition bed of material is arranged on the slope of the checkdam matrix upstream face inside described padding layer.
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 base impervious drop ply be made up of horizontal geomembrane, described base impervious drop ply and described domatic anti-leakage layer place bottom the upstream face slope of the described checkdam matrix of trapezium structure is tightly connected.
Further, to be describedly tightly connected as being welded to connect.
Further, between described base impervious drop ply and described covering layer, bottom padding layer is also provided with.
Further, between described base impervious drop ply and described checkdam matrix, top padding layer is also provided with.
Further, be also provided with vertically upwards along the inner bag anti-leakage structure stretched in the lateral middle of described checkdam matrix, described inner bag anti-leakage structure is longitudinally along stretching the two ends causing described checkdam matrix.
Further, described inner bag anti-leakage structure is upwards made up of along the vertical geomembrane stretched indention.
The invention has the beneficial effects as follows: to be built by rock ballast stockpile due to the checkdam matrix forming described checkdam structure and form, then on the described checkdam matrix upstream face slope of being built from rock ballast stockpile, be furnished with fixed bed and domatic anti-leakage layer from outer successively toward interior.Thus 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, effectively can also extend the seepage paths of described checkdam dam body, reduce downstream penetration amount, improve osmotic stability.
Accompanying drawing explanation
Fig. 1 is the present invention for the cross-sectional structure schematic diagram of the checkdam structure in hydroelectric project coombe or river course.
Be labeled as in figure: checkdam matrix 1, fixed bed 2, domatic anti-leakage layer 3, padding layer 4, the anti-filter transition bed of material 5, covering layer 6, base impervious drop ply 7, bottom padding layer 8, top padding layer 9, inner bag anti-leakage structure 10.
Detailed description of the invention
Be that a kind of structure provided by the invention is simple as shown in Figure 1, the checkdam structure for hydroelectric project coombe or river course of low in investment cost.Described checkdam structure comprises the checkdam matrix 1 built by rock ballast stockpile, described checkdam matrix 1 is projected as trapezium structure in its cross section, and the upstream face slope of the described checkdam matrix 1 of trapezium structure is furnished with fixed bed 2 and domatic anti-leakage layer 3 from outer successively toward interior.To be built by rock ballast stockpile due to the checkdam matrix 1 forming described checkdam structure and form, then on the described checkdam matrix 1 upstream face slope of being built from rock ballast stockpile, be furnished with fixed bed 2 and domatic anti-leakage layer 3 from outer successively toward interior.Thus effectively simplify the structure of described checkdam, and then simplify working procedure, shorten the construction period and reduce cost of production, simultaneously, because described fixed bed 2 and domatic anti-leakage layer 3 are arranged on the upstream face slope of described checkdam matrix 1, effectively can also extend the seepage paths of described checkdam dam body, reduce downstream penetration amount, improve osmotic stability.
In above-mentioned embodiment, in order to reduce cost of production to greatest extent, described domatic anti-leakage layer 3 is for being covered in the sloping core geomembrane on the described checkdam matrix 1 upstream face slope of trapezium structure, and better fixing described sloping core geomembrane, described fixed bed 2 is set to cover solid bank protection layer outside described sloping core geomembrane.
In conjunction with structure, the shape of existing rock ballast material, in order to avoid described sloping core geomembrane is in use scratched broken base by described rock ballast material, thus the maintenance, repair cycle of checkdam described in extending, reach the application life extending described checkdam, described checkdam structure also comprises padding layer 4 and the anti-filter transition bed of material 5, and described padding layer 4 is arranged on the slope of checkdam matrix 1 upstream face inside described domatic anti-leakage layer 3; The described anti-filter transition bed of material 5 is arranged on the slope of the checkdam matrix upstream face inside described padding layer.
Simultaneously, in order to increase the stability of described checkdam structure dam body, reduce seepage to damage dam body, in conjunction with described in checkdam matrix 1 heap build in described hydroelectric project coombe or river course covering layer 6 on feature, the base impervious drop ply 7 be made up of horizontal geomembrane is also furnished with between described covering layer 6 and described checkdam matrix 1, described base impervious drop ply 7 is tightly connected with described domatic anti-leakage layer 3 place bottom the upstream face slope of the described checkdam matrix 1 of trapezium structure, is preferably tightly connected as being welded to connect.Equally, in order to protect the base impervious drop ply 7 be made up of horizontal geomembrane, between described base impervious drop ply 7 and described covering layer 6, bottom padding layer 8 is also provided with; Top padding layer 9 is also provided with between described base impervious drop ply 7 and described checkdam matrix 1.
