Description
Technical field
The present invention relates to hydraulic engineering technical field, the impervious watertight structure in more particularly to a kind of hydraulic engineering.
Background technology
Dam is block rivers ditch water flow with raising of water level or the water retaining structure of regulation flow.Reservoir can be formed, is lifted
High water level, regulated flow, concentration head, for flood control, water supply, irrigation, hydroelectric generation, improve shipping etc..Adjustment river gesture, protection
The river regulating structure of bank bed is also referred to as dam, such as groynes, longitudinal dike and ground sills etc..
Due to the gigantic project of building of dam, it is to be built using local material mostly, and the infiltration leak that dam is caused is tired
A big problem of people is disturbed, is generally prevented by intercepting using leakage preventing structure (gravel, Colophonium, concrete, geomembrane etc.) at present
Seepage is sent out, but causes the factor of dam seepage to have multiple, and in addition to inherent structure reason, extraneous factor is also highly important
Reason, although as constructed leakage preventing structure, as Coptotermes formosanus Shtrari. is nested, the leakage preventing structure is destroyed, so as to cause dam to seep water
The situation of leak happens occasionally, and therefore how designing one kind can prevent nature seepage from can prevent the non-natural damage of the insect pests such as Coptotermes formosanus Shtrari. again
Bad impervious watertight structure is extremely necessary.
Content of the invention
For solving problem above, the technical problem to be solved in the present invention is to provide a kind of knot of the water seepage prevention in hydraulic engineering
Structure.
It is the impervious watertight structure in a kind of hydraulic engineering of the invention up to above-mentioned purpose, including dam body, the water seepage prevention
Structure includes the dam body seepage layer positioned at the dam body obstructing surface from dam crest to dam bottom, the seepage prevention of dam founda in the dam foundation of dam body bottom
Layer, is provided with antiseepage articulamentum between the dam body seepage layer and the seepage prevention of dam founda layer, the antiseepage articulamentum is externally provided with middle part
Barrier layer, the middle part barrier layer are ventilating structure, are filled with anthelmintic in which.
Wherein described dam body seepage layer is that concrete layer vertically interts poly tetrafluoroethylene composition.
Wherein described poly tetrafluoroethylene is multilamellar, alternates in the concrete layer.
Wherein described antiseepage articulamentum is C/C composite plates, the C/C composite plates and the poly tetrafluoroethylene welding.
Wherein described seepage prevention of dam founda layer is double-deck oxidation copper coin, and the C/C composite plates bottom is sandwiched in the double-deck copper oxide
Welding behind plate centre.
Wherein described dam body seepage layer is gradually thickening the bottom of to by pushing up.
Wherein described seepage prevention of dam founda layer from top to bottom narrows successively from the dam foundation.
Wherein described middle part barrier layer is removable installed on the antiseepage articulamentum outer layer.
The invention difference from existing technology is that the present invention achieves following technique effect：
1st, the present invention passes through to arrange middle part barrier layer, and will house anthelmintic drug in the barrier layer of middle part, effectively can prevent
The insect pests such as Coptotermes formosanus Shtrari. destroy the leakage preventing structure, effectively avoid the seepage of dam；
2nd, the present invention arranges the dam dam that from top to bottom thickness increases successively with reference to water gravity, impact flow power etc. in dam
The seepage prevention of dam founda layer that from top to bottom thickness is sequentially reduced is set in body impervious barrier, the dam foundation, is connected by antiseepage articulamentum between two-layer
Connect, under the conditions of water seepage prevention is met, appropriate design structure reduces material usage, increases space availability ratio；
3rd, dam body seepage layer of the present invention passes through concrete layer and polytetrafluoroethylene floor interval setting, in conjunction with the advantage of the two,
Can reduces cost, corrosion resistance can be improved again, so as to farthest improve water seepage prevention ability；
4th, antiseepage articulamentum of the present invention selects C/C composites, can prevent dam body to greatest extent with dam foundation junction
Water seepage prevention, by with dam body seepage layer in polytetrafluoroethylene floor welding, it is possible to increase the bond strength of junction, effectively
The occurrence of avoiding water seepage prevention；
5th, using double-deck oxidation copper coin, C/C composites end is located in double-deck oxidation copper coin seepage prevention of dam founda layer of the present invention
Between after will oxidation copper coin welding, improve the binding ability of C/C composites and oxidation copper coin seam crossing, can effectively reduce soil
Dielectric corrosion, can improve water seepage prevention performance again.
The invention will be further described below in conjunction with the accompanying drawings.
