Description
Technical field
The utility model is specifically related to a kind of reservoir seepage-proofing structure, belongs to hydraulic engineering technical field.
Background technology
Reservoir is the important ring in hydraulic engineering, specifically refers to the artificial lake formed after the narrow orifice place in gully or river builds barrage, and after building up, reservoir generally can play flood control, catchwork irrigation, water supply, generate electricity, the effect such as to breed fish.Reservoir there will be the phenomenon of seepage unavoidably in running, if leakage scenarios is in design allowed band, not bad, if leakage is excessive exceed design allowed band, then engineering safety can be threatened, there is huge potential safety hazard, therefore reservoir seepage-proofing leaks in reservoir construction runs is very important link.
At present, a lot of reservoir seepage-proofing leaks and realizes by laying geomembrane at Reservoir Surface, the water resistance of geomembrane is fine, but because hydraulic pressure long duration of action, landform are more changeable and reservoir bottom the many reasons such as sedimentation and deformation can occur, often can only be used for interim engineering leakproof, cannot Long-Time Service.
Summary of the invention
The utility model solves prior art Problems existing, proposes a kind of reservoir seepage-proofing structure, and this reservoir seepage-proofing structure, to reservoir stress deformation strong adaptability, can meet the antiseep demand that reservoir is long-term.
Technical solutions of the utility model are as follows: a kind of reservoir seepage-proofing structure of the utility model, comprises from the extended leveling layer of reservoir top-to-bottom; Also comprise the bed course set gradually from bottom to up, geo membrane layers and the layer of concrete be located at above leveling layer; Described leakage preventing structure is provided with fastening devices, it is characterized in that, is provided with stress compensation layer above described layer of concrete, re-lays one deck layer of concrete above described stress compensation layer; Described stress compensation layer comprises some pieces of metal plates and metal corrugated plate, and described metal plate and metal corrugated plate interval arrange and weld together.
Described metal plate and metal corrugated plate adopt copper coin.
Described metal plate and metal corrugated plate adopt corrosion resistant plate.
Described fastening devices comprises fixed screw or rivet, and described fastening devices penetrates layer of concrete, stress compensation layer, layer of concrete, geo membrane layers, bed course and leveling layer successively, extends to below reservoir leveling layer.
Described bed course is soft bed course.
The beneficial effects of the utility model: a kind of reservoir seepage-proofing structure of the utility model, leveling layer, bed course, geo membrane layers, layer of concrete, sheet-metal layers and layer of concrete is provided with successively bottom reservoir, geomembrane has extraordinary water resistance, sheet-metal layers also has extraordinary leak-preventing ability simultaneously, add that sheet-metal layers comprises some pieces of metal plates and metal corrugated plate, described metal plate and metal corrugated plate interval arrange and weld together, compensate for the reservoir distortion that the effect of water pressure iso-stress causes like this, there is goodish ductility.

Detailed description of the invention
As shown in Figure 1, a kind of reservoir seepage-proofing structure of the utility model, comprises and has leveling layer (25) from reservoir top-to-bottom is extended; Leveling layer (25) is provided with leakage preventing structure (2).
As shown in Figure 2, the utility model leakage preventing structure (2) also comprises the bed course (24) set gradually from bottom to up, geo membrane layers (23) and the layer of concrete (21) be located at above leveling layer; Described leakage preventing structure (2) is provided with fastening devices (3), described layer of concrete (21) top is provided with stress compensation layer (22), and described stress compensation layer (22) top re-lays one deck layer of concrete (21);
As shown in Figure 3, stress compensation layer described in the utility model (22) comprises some pieces of metal plates (222) and metal corrugated plate (221), and described metal plate (222) and metal corrugated plate (221) interval arrange and weld together.Described metal plate (222) and metal corrugated plate (221) adopt copper coin or corrosion resistant plate.
This form of structure of stress compensation layer (22), arranged by the interval of metal corrugated plate (221) and metal plate (222) and realize stress compensation effect, when the effect of hydraulic pressure iso-stress causes reservoir deformation of bottom time, metal corrugated plate (221) has ductility, the absorption of stress can well be realized, adapt to the distortion of reservoir (1), better play the effect of antiseepage.
The utility model is also provided with some fastening devicess (3) at leakage preventing structure (2) and is used for reinforcing anti-seepage structure (2), described fastening devices (3) comprises fixed screw or rivet, described fastening devices (3) penetrates layer of concrete (21), stress compensation layer (22), layer of concrete (21), geo membrane layers (23), bed course (24) and leveling layer (25) successively, extends to leveling layer (25) below.Described bed course (24) is soft bed course.
A kind of reservoir seepage-proofing structure of the utility model, leveling layer, bed course, geo membrane layers, layer of concrete, sheet-metal layers and layer of concrete is provided with successively bottom reservoir, geomembrane has extraordinary water resistance, sheet-metal layers also has extraordinary leak-preventing ability simultaneously, add that sheet-metal layers comprises some pieces of metal plates and metal corrugated plate, described metal plate and metal corrugated plate interval arrange and weld together, compensate for the reservoir distortion that the effect of water pressure iso-stress causes like this, there is goodish ductility.
