Description
Technical field
The utility model relates to a kind of anti-leakage structure, particularly relates to a kind of reservoir seepage-proofing drain structure.
Background technology
The effects such as reservoir, is the important ring in hydraulic engineering, specifically refers at the narrow orifice place in gully or river and builds the artificial lake who forms after barrage, and after building up, reservoir generally can play flood control, catchwork irrigation, water supply, generate electricity, breed fish.The reservoir phenomenon that there will be unavoidably seepage in service, if seepage situation is in design allowed band, not bad, if the excessive design allowed band that surpasses of leakage, can threaten engineering safety, there is huge potential safety hazard, thus reservoir seepage-proofing to leak in service at reservoir construction be very important link.At present; a lot of reservoir seepage-proofings leak by laying geomembrane at Reservoir Surface to be realized; generally comprise the topping, geotechnological rete, bed course, the leveling layer that connect successively from top to bottom, leveling layer is fixed on Reservoir Surface, and geotechnological rete is formed by multiple geomembrane tilings.The water resistance of geomembrane is fine, but due to hydraulic pressure long duration of action, landform is more changeable and sedimentation and deformation can occur reservoir bottom, so being positioned at the part of Reservoir Surface bent angle, the joint between multiple geomembranes and geomembrane there will be gap and loosening, the geomembrane breakage that also may be stretched, causes existing the hidden danger of seepage.
Summary of the invention
The technical problems to be solved in the utility model is to provide provides a kind of reservoir seepage-proofing drain structure, and leakage performance is better.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A reservoir seepage-proofing drain structure, comprises the topping being arranged on Reservoir Surface, geotechnological rete, bed course, leveling layer, and described topping, geotechnological rete, bed course, leveling layer connect from top to bottom successively, and described leveling layer is fixed on Reservoir Surface,
Described geotechnological rete comprises some composite geo-membranes, described some composite geo-membranes are laid on bed course, the joint of described every adjacent two composite geo-membranes is provided with pressure plate structure one, described pressure plate structure one comprises pressing plate one, dormant bolt one, described pressing plate one is plane stainless steel plate, described pressing plate one is pressed on the joint of adjacent two composite geo-membranes, described dormant bolt one is successively through being fixedly connected on the built-in fitting one of Reservoir Surface below after pressing plate one, composite geo-membrane, bed course, leveling layer
Described Reservoir Surface has bent angle, the part that described composite geo-membrane is positioned at Reservoir Surface bent angle is provided with pressure plate structure two, described pressure plate structure two comprises pressing plate two, dormant bolt two, described pressing plate two is the cross section corrosion resistant plate consistent with Reservoir Surface bent angle shape, described pressing plate two is pressed in the part that composite geo-membrane is positioned at Reservoir Surface bent angle, and described dormant bolt two is successively through being fixedly connected on the built-in fitting two of Reservoir Surface below after pressing plate two, composite geo-membrane, bed course, leveling layer.
Preferably, topping described in the utility model is concrete cover.
Preferably, composite geo-membrane described in the utility model is two cloth one films.
Preferably, bed course described in the utility model is flexible cushion.
Therefore, compared with prior art, the utlity model has following beneficial effect:
Pressure plate structure one can effectively fix the junction between composite geo-membrane, pressure plate structure two can effectively fix the part that composite geo-membrane is positioned at Reservoir Surface bent angle, therefore the composite geo-membrane of these two positions there will not be loosening and gap, even if can be stretched, destroy also having pressing plate and push down, greatly reduce the hidden danger of infiltration.
