Abstract
The utility model discloses a ballast field structure at an earth and rockfill dam toe. A ballast field is arranged at the dam toe of an earth and rockfill dam. The ballast field comprises ballast piled-up bodies, a ballast piled-up body transition layer, a ballast field foundation drainage layer, ballast field top drainage ditches and earth-up green areas. The gradient of the upper stream of the ballast field is the same as the gradient of the lower stream of a dam body of the earth and rockfill dam. Slopes are cut and grades are formed at the lower stream of the ballast field. The ballast piled-up body transition layer is arranged between the ballast piled-up bodies and filling materials of the earth and rockfill dam. The ballast field foundation drainage layer is connected with a dam foundation drainage layer of the earth and rockfill dam. The ballast field top drainage ditches are arranged at the junction positions of the ballast piled-up bodies, the earth and rockfill dam and mountains, and connected with drainage ditches of the earth and rockfill dam and the mountains. The earth-up green areas are arranged at the top face of the ballast field and the lower stream slope face of the ballast field. Due to the fact that the ballast field is arranged at the dam toe of the earth and rockfill dam, land acquisition and immigrants of the ballast field and connecting roads of the ballast field can be reduced, the engineering protection amount and the waste ballast haul distance of the ballast field are reduced, the stability of the dam body is improved, and environment in the dam area is beautified.
