Waste rockfill dam and damming method of waste rockfill dam
The invention provides a barren rock dam and a damming method of the barren rock dam. The waste rock dam comprises a plurality of dam body layers which are sequentially stacked, each dam body layer comprises a foundation dam located on the upstream and a throwing and filling platform located on the downstream, the foundation dams are formed by rolling and stacking, the throwing and filling platforms are formed by throwing and filling, and the throwing and filling platforms extend from the downstream sides of the foundation dams to the downstream direction. According to the material properties and structural characteristics of the waste rock dam, the method of combining rolling damming and throwing and filling damming is adopted, the effect that the upstream impermeable layer is stable in structure and reliable in operation is achieved, the damming cost is greatly reduced, transportation equipment is reduced, and the construction operation progress is greatly accelerated. And meanwhile, the foundation can be pre-pressed in advance, and the method is particularly suitable for large-scale waste rock dam heaping, and particularly suitable for dam body filling under complex geological conditions such as soft foundation areas and high earthquake areas.
本发明提供了一种废石坝和废石坝的筑坝方法。废石坝包括依次叠置的若干坝体层，所述坝体层包括位于上游的基础坝和位于下游的抛填平台，所述基础坝由碾压堆筑而成，所述抛填平台由抛填而成，所述抛填平台从所述基础坝的下游侧向下游方向延伸。本发明根据废石坝的物料性质及结构特点，结合地形条件，采用碾压筑坝与抛填筑坝相结合的方法，实现上游防渗层结构稳定，运行可靠，又大大降低筑坝成本，减少运输设备，大大加快施工作业进度。同时，还可以提前对基础进行预压处理，特别适用于大规模废石坝堆筑，特别是软基地区、高震区等复杂地质条件下的坝体填筑。
