Fiber reinforced recycled concrete face rockfill dam structure

Abstract

The utility model provides a fiber reinforced recycled concrete face rock-fill dam structure, which is characterized in that the upstream surface of a rock-fill body of a rock-fill dam adopts a polypropylene fiber reinforced recycled concrete face, and the structural problem of recycled aggregate is solved by means of fiber characteristics; the dam top plane of the concrete faced rockfill dam is arranged in an arc shape protruding towards the downstream, and the turning part is in circular arc uniform transition. The ends of the arc-shaped face plates are in a circular arc shape, and the ends are connected through a sliding type lap joint method to form the recycled concrete face plates with the thicknesses gradually increased from the dam top to the dam foundation. And the annular water stop is arranged between the arc-shaped panels, so that the water stop effect of the structure is improved. The scheme that polypropylene fiber materials and the dam crest are arranged in an arc shape is adopted, the crack resistance of the recycled concrete face plate is enhanced, the stress state of the face plate is improved, and meanwhile the recycled concrete technology has the advantages of achieving resource recycling, reducing carbon emission, being excellent in heat preservation and heat insulation and the like.
