Abstract
The utility model discloses the library basin leakage preventing structures for being suitable for library in hydroenergy storage station described in one kind, including excavating the library basin slope surface constituted；The library basin slope surface is made of armored concrete panel or/and pneumatically placed concrete panel, is successively coated with interface agent layer and two-component polyurea coating on the surface of the armored concrete panel or/and pneumatically placed concrete panel.The utility model advantage is that anti-seepage effect is reliable, and construction investment is small, has well solved basin antiseepage problem in Kuku in hydroenergy storage station.After the utility model leakage preventing structure, observed through returning Kuku basin in imperial hydroenergy storage station to jade mine in Nanyang, Henan Province, leakage is only 10 ~ 20 liters/day, is accomplished substantially watertight.
Description
Technical field
The utility model relates to Kuku basins in hydroenergy storage station, more particularly, to the library for being suitable for library in hydroenergy storage station
Basin leakage preventing structure.
Background technique
In pumping energy storage power station project, the height of water in general Shang Ku and lower library is between 400m ~ 600m, the water in upper library
It is to be pumped with the hydraulic turbine from Xia Ku, needs to consume a large amount of electric energy, if upper Kuku basin leakage is larger, not only will cause
Biggish economic loss, and structure safety and surrounding enviroment are adversely affected, therefore, the antiseepage requirement to upper Kuku basin
It is higher.
General common library basin anti-seepage scheme has armored concrete panel, asphalt concrete face slab, clay, geomembrane etc.,
More or less there is the problems such as leakage is bigger than normal or project cost is higher in these methods.
Summary of the invention
The utility model aim is to provide a kind of library basin leakage preventing structure suitable for library in hydroenergy storage station, to solve to take out
Basin antiseepage problem in Kuku in water storage station.
To achieve the above object, the utility model takes following technical proposals:
Library basin leakage preventing structure described in the utility model suitable for library in hydroenergy storage station, including excavating the Ku Penpo constituted
Face；The library basin slope surface is made of armored concrete panel or/and pneumatically placed concrete panel, the armored concrete panel or/
Interface agent layer and two-component polyurea coating are successively coated with the surface of pneumatically placed concrete panel.
Surface drying time≤6h, the bond strength >=2.5MPa of the interface agent layer；The stretching of the two-component polyurea coating
Intensity >=20MPa, elongation at break >=350%, bond strength >=2.5MPa, impermeability >=0.4MPa × 2h.
The two-component polyurea coating with a thickness of 3mm.
The invention has the advantages that anti-seepage effect is reliable, construction investment is small, has well solved Kuku in hydroenergy storage station
Basin antiseepage problem.After the utility model leakage preventing structure, seen through returning Kuku basin in imperial hydroenergy storage station to jade mine in Nanyang, Henan Province
It surveys, leakage is only 10 ~ 20 liters/day, is accomplished substantially watertight.
Detailed description of the invention
Fig. 1 is that armored concrete panel surface described in the utility model smears interfacial agents, the structure of spray polyurea coating is shown
It is intended to.
Fig. 2 is the structural representation that pneumatically placed concrete panel surface described in the utility model smears interfacial agents, spray polyurea coating
Figure.
Specific embodiment
Library basin leakage preventing structure described in the utility model suitable for library in hydroenergy storage station, including excavating the Ku Penpo constituted
Face；Do not plan a successor, in the library basin slope surface of developmental joint fissure pouring reinforcement concrete constitute armored concrete panel 1, remaining
Library basin slope surface pneumatically placed concrete constitute pneumatically placed concrete panel 2.
It is less than the thin layer rejected region of 3mm for 1 surface pores of armored concrete panel, voids and pits, thickness, by its base
Face carries out being locally filled with repairing after cleaning out using epoxy mortar, then smears interfacial agents on 1 surface of armored concrete panel
1.1, interfacial agents 1.1 to be described spray 3mm thickness two-component polyurea coating 1.2 after solidifying.
High-strength cement mortar is smeared after polishing for the laitance on 2 surface layer of pneumatically placed concrete panel, then twice of screed-coat, often
Then a time levelling minimum thickness 1.5cm, screed-coat minimum thickness 3cm smear interfacial agents 2.1 on 2 surface of pneumatically placed concrete panel,
3mm thickness two-component polyurea coating 2.2 is sprayed after the solidification of interfacial agents 2.1.
Interfacial agents surface drying time≤6h, the bond strength >=2.5MPa of above-mentioned smearing；The two-component polyurea coating of spraying is drawn
Stretch intensity >=20MPa, elongation at break >=350%, bond strength >=2.5MPa, impermeability >=0.4MPa × 2h.
During jade mine in Nanyang, Henan Province returns Kuku basin Anti-seeping technology in imperial hydroenergy storage station, original adoption armored concrete
Panel and pneumatically placed concrete panel option antiseepage, leakage about 10000m3/ day；Afterwards to library basin pneumatically placed concrete panel area and part steel
Reinforced concrete panel carries out molten PVC modified pitch of smearing and carries out Anti-seeping technology, and leakage is reduced to 1482 m3/ day；By more than 10 years
Operation after, with the aging of modified pitch, leakage is gradually increased to 2638 m3/ day.Finally, using the utility model
Structure carries out Anti-seeping technology, and through observing, leakage is only 10 ~ 20 liters/day.
