Description
Technical field
The utility model relates to a kind of water conservancy projects, especially a kind of masonry gravity dam.
Background technology
Masonry gravity dam is the large volume shelves water buildings that stone masonry is built, and its fundamental profile is right-angled triangle, and entirety is made up of some monoliths.Gravity dam is under water pressure and other load actions, and the main skid resistance relying on dam body deadweight to produce meets stability requirement; The pressure simultaneously relying on dam body deadweight to produce offsets tensile stress caused by water pressure to meet requirement of strength.
Therefore, gravity dam must meet stability requirement and requirement of strength under water pressure and other load action.
Summary of the invention
The utility model provides a kind of masonry gravity dam, and this gravity dam has higher stability and intensity, more effectively can offset the tensile stress caused by water pressure.
The utility model solves the technical scheme that its technical problem adopts: the dam facing comprising the vertical vertical masonry gravity dam of the dam facing that is arranged in upstream and be arranged in downstream is the oblique masonry gravity dam on slope, water-conveyance culvert or pipe is furnished with in dam body, it is the dam foundation of consolidation grouting below dam body, grouted cut off wall is provided with below the dam foundation that vertical masonry gravity dam is corresponding, concrete core-wall is provided with between described vertical masonry gravity dam and oblique masonry gravity dam, concrete core-wall lower end is fixed in the dam foundation, the upper strata of described oblique masonry gravity dam comprises Overflow Section and left and right banks non-overflow section of dam, the spillwag chute of Overflow Section is fixed on oblique masonry gravity dam by anchor pole, also absorption basin is provided with in oblique masonry gravity dam downstream, absorption basin is made up of base plate and baffle plate, the base plate of absorption basin is provided with drain hole.
A kind of masonry gravity dam of the present utility model, not only there is the vertical masonry gravity dam that face is vertical, its dam body tilted also is stone masonry material, the structure of oblique masonry gravity dam is beneficial to the deadweight adding Monolithic Gravity Dams, thus maintain stable better, the dam foundation of consolidation grouting and the concrete core-wall between vertical masonry gravity dam and oblique masonry gravity dam all serve the effect strengthening overall structure steadiness, simultaneously, also absorption basin is provided with in oblique masonry gravity dam downstream, and drain hole is provided with on the base plate of absorption basin, effectively counteract again the tensile stress caused by water pressure, therefore gravity dam combination property of the present utility model is good.
