Technical field
The utility model belongs to water conservancy project building technical field, is specifically related to the leakage preventing structure that a kind of reservoir bottom geomembrane is connected with the storehouse all side seams of week collector drain.
Background technology
The high-land of pumped storage power plant upper storage reservoir, natural water or runoff are few, to antiseepage, require high.Collector drain concrete edge and non-fine concrete have a common boundary, non-fine concrete is provided with concrete slab, concrete slab also has a common boundary with collector drain concrete edge, between collector drain concrete edge and non-fine concrete and concrete slab, has gap, is collector drain week side seam; And between concrete slab and non-fine concrete, also there is gap, i.e. vertical lap seam.In prior art, concrete slab top is provided with SR antiseepage cover plate, collector drain week side seam top is provided with a SR antiseepage arc cover plate, and this SR antiseepage arc cover plate is connected with SR antiseepage cover plate, in SR antiseepage cover plate and SR antiseepage arc cover plate, is all filled with SR flexible filler; SR antiseepage cover plate covered collector drain week side seam.Concrete slab and non-fine concrete intersection are provided with W1 type copper seal, are provided with F1 type copper seal in collector drain concrete, and F1 type copper seal is connected with W1 type copper seal.Because geomembrane does not cover collector drain week side seam place, be equivalent to total this one waterproof of SR antiseepage cover plate afterwards, there is serious storehouse seepage problem in collector drain week side seam place.When SR antiseepage cover plate destroys, reservoir infiltration will enter bottom of the reservior by all side seams of collector drain along vertical lap seam.Therefore, well antiseepage of existing leakage preventing structure.
Utility model content
The utility model is intended to overcome the deficiencies in the prior art, the leakage preventing structure that provides a kind of reservoir bottom geomembrane to be connected with the storehouse all side seams of week collector drain.
In order to achieve the above object, technical scheme provided by the invention is:
The leakage preventing structure that a kind of reservoir bottom geomembrane is connected with the storehouse all side seams of week collector drain, comprise bottom of the reservior geomembrane, the all side seams of described collector drain are collector drain concrete edge and non-fine concrete and are located at the gap between the concrete slab on non-fine concrete, described collector drain week side seam top is provided with SR arc antiseepage cover plate, in described collector drain concrete, be provided with F1 type copper seal, in described concrete slab, be provided with W1 type copper seal, described F1 type copper seal is connected with W1 type copper seal; It is characterized in that, described bottom of the reservior geomembrane covers all side seams of collector drain and is pressed solidly by SR arc antiseepage cover plate; In described collector drain concrete, be provided with water-swellable sealing rod, water-swellable sealing rod bottom is fixed on F1 type copper seal, and water-swellable sealing rod top is stretched in the SR flexible filler in SR arc antiseepage cover plate; In described concrete slab, be provided with W3 type copper seal, W3 type copper seal bottom is fixed on W1 type copper seal, and W3 type copper seal top is stretched in the SR flexible filler in SR arc antiseepage cover plate.
Wherein, described SR arc antiseepage cover plate is ethylene propylene diene rubber enhancement mode antiseepage SR cover plate.Described bottom of the reservior geomembrane is pressed solidly by bolt and nut by SR arc antiseepage cover plate, and the place of pressing solidly is followed successively by SR primer layer, SR leveling layer, SR primer layer, bottom of the reservior geomembrane, SR primer layer and SR antiseepage arc cover plate from the bottom to top.
In structure of the present utility model, not only retained SR antiseepage cover plate and the SR flexible filler in existing structure, and bottom of the reservior geomembrane is extended to collector drain week side seam, cover this gap, formed a complete top layer seepage control system, prevented the storehouse seepage at collector drain week side seam place.On the other hand, leakage preventing structure of the present utility model arranges water-swellable sealing rod in all collector drain concrete in storehouse, W3 type copper seal is set in concrete slab, when the SR at concrete slab top antiseepage cover plate and SR flexible filler destroyed, when water seepage flow gets off, W3 type copper seal has stopped that as the baffle plate of concrete slab side water is further penetrated into collector drain and bottom of the reservior, even if there is water to see through W3 type copper seal, after the water-swellable sealing rod of collector drain concrete one side is met water, expand, also can block water continue to be penetrated into collector drain and bottom of the reservior.
Compared with prior art, the utlity model has good seepage-proof property, the feature such as required input construction equipment is few, speed of application is fast, cost is low, reduced investment,, there is good promotional value.
