Abstract

The utility model belongs to the technical field of the water conservancy water and electricity and specifically relates to a seepage prevention structure is united to checkdam. The utility model aims to solve the technical problem that a seepage prevention structure is united to checkdam that more reliably, the more economic cut -pff wall effect of improving is provided. Seepage prevention structure is united to checkdam, including the dam body, the bottom of dam body is provided with the concrete cut -pff wall, the upstream side of concrete cut -pff wall is provided with the prevention of seepage geomembrane, be provided with the water proof structure in the clearance between dam body and the concrete cut -pff wall. The utility model discloses creative simplification the prevention of seepage mode between dam body and the concrete cut -pff wall, messenger's engineering prevention of seepage effect is better to reduce the engineering risk, meanwhile, it is also more convenient to be under construction, and the cost is low. The utility model discloses be particularly useful for among the prevention of seepage processing of water conservancy water and electricity checkdam.

Description

Checkdam associating leakage preventing structure
Technical field
This utility model relates to field of water conservancy, especially a kind of checkdam associating leakage preventing structure.
Background technology
In field of water conservancy, it is often necessary to checkdam is carried out Anti-seeping technology.Cut-pff wall is that one is built at loose pervious bed Or earth and rockfill dam (weir) plays the diaphram wall of antiseepage effect.Cut-pff wall technology originates from Europe in the 1950's, because of Its structure is reliable, good seepage-proof property, all kinds of formation condition of adaptation, easy construction and the advantage such as cost is low, is especially processing Behind leakage of dam foundation, dam respond well on the seepage deformation potential problem such as " stream soil ", " piping ", at home and abroad obtained extensively Application.China's water conservancy and hydropower cover layer and earth rock cofferdam etc. have the typically first-selected cut-pff wall of Anti-seeping technology of anti-consolidation pressure.Often use The cut-pff wall structure of rule is often difficult to reach to expect preferable effect because of the reason such as construction quality, deformation, in addition it is also necessary to carry out repairing, Repair, affect long-term safety and run.Therefore, in the face of such problem so that need to use more reliable when seepage prevention design Engineering measure.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of more reliable, more economical checkdam improving cut-pff wall effect Associating leakage preventing structure.
This utility model solves its technical problem the technical scheme is that checkdam associating leakage preventing structure, including dam body, institute The bottom stating dam body is provided with concrete cut, and the upstream side of described concrete cut is provided with anti-seepage geomembrane, described dam It is provided with water-stop structure in gap between body and concrete cut.
Further, it is provided with copper seal structure in the gap between described dam body and concrete cut.
Further, it is provided with rubber water-proof band structure in the gap between described dam body and concrete cut.
Further, including foundation plane, described copper seal structure is perpendicular arranges in foundation plane.
Further, including foundation plane, described rubber water-proof band structure is arranged in being parallel to foundation plane.
Further, described water-stop structure is plastic mortars.
The beneficial effects of the utility model are: the antiseepage simplified between dam body and concrete cut that this utility model is creative Mode, first, carries out main antiseepage by being arranged at the anti-seepage geomembrane of the upstream side of cut-pff wall, next, for dam Gap between body and concrete cut, then carry out further antiseepage by water-stop structure, and described water-stop structure also may be used To be replaced easily in using in the later stage.Structure of the present utility model makes project seepage controlling effect more preferable, thus reduces engineering wind Danger, meanwhile, constructs the most convenient, and cost is low.This utility model is particularly suited at the antiseepage of water conservancy and hydropower checkdam Among reason.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Figure is labeled as: dam body 1, concrete cut 2, anti-seepage geomembrane 3, rubber water-proof band structure 4, copper seal are tied Structure 5, water-stop structure 6, foundation plane 7.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further illustrated.
Checkdam associating leakage preventing structure as shown in Figure 1, including dam body 1, the bottom of described dam body 1 is provided with concrete anti-seepage Wall 2, the upstream side of described concrete cut 2 is provided with anti-seepage geomembrane 3, between described dam body 1 and concrete cut 2 Gap in be provided with water-stop structure 6.
When practice of construction, use design structure of the present utility model can realize antiseepage efficiently and effectively.First, such as Fig. 1 Shown, the upstream side of concrete cut 2 is provided with anti-seepage geomembrane 3, can farthest realize antiseepage, certain, Anti-seepage geomembrane 3 can also be also provided with according to actual needs in the downstream of concrete cut 2.It addition, for dam body 1 And the gap between concrete cut 2, this utility model then realizes antiseepage by water-stop structure 6, even if the later stage occurs in that Water-stop structure 6 change needs, it is also possible to the most easily change water-stop structure 6.General, described water-stop structure 6 is preferred For plastic mortars.
Certainly, in order to further improve the anti-seepage effect in the gap between dam body 1 and concrete cut 2, can select Copper seal structure 5 is set in the gap between described dam body 1 and concrete cut 2, moreover, selects on dam Rubber water-proof band structure 4 it is provided with in gap between body 1 and concrete cut 2.As shown in Figure 1, such design Can more effectively realize the effect of antiseepage, and substantially prolongs the service life of water-stop structure 6.General, with foundation plane 7 For reference datum, preferably arrange perpendicular for described copper seal structure 5 in foundation plane 7, and rubber water-proof band structure 4 Arranging in being parallel to foundation plane 7, such waterproof effect is optimal.
Structure of the present utility model makes project seepage controlling effect more preferable, thus reduces engineering risk, and meanwhile, construction is the most just Victory, cost is low, has the most wide marketing prospect.
