Concrete faced rockfill dam structure based on earth-rock space-time balance and construction method of concrete faced rockfill dam structure
The invention provides a concrete faced rockfill dam structure based on earth-rock space-time balance, a rockfill body is arranged in a concrete faced rockfill dam, a main rockfill area and a secondary rockfill area are sequentially arranged in the rockfill body from upstream to downstream, and a waste slag filling body is arranged on the downstream face of the rockfill body. The waste slag filling body comprises a first waste slag area and a second waste slag area which are sequentially filled from bottom to top, and the upstream section part of the first waste slag area is arranged at the bottom of the secondary rockfill area in advance; a foundation drainage structure is arranged between the downstream of the dam axis of the concrete faced rockfill dam and a dam foot, and the foundation drainage structure comprises a drainage box culvert arranged below a rockfill body and a waste slag filling body. The drainage box culvert is used as a foundation drainage structure of the dam, and the downstream waste slag body is additionally arranged, so that waste slag and secondary rockfill materials in the early stage of engineering excavation have filling conditions, arrangement of a waste slag field and a transfer material field is reduced, and the damage of earth-rock engineering on the environment is relieved.
本发明提供了基于土石方时空平衡的面板堆石坝结构，面板堆石坝内设置堆石体，所述堆石体内自上游至下游依次设置的主堆石区和次堆石区，所述堆石体的下游面设置弃渣填筑体，所述弃渣填筑体包括由下而上依次填筑的弃渣一区和弃渣二区，所述弃渣一区的上游段部分预先设置于次堆石区底部；所述面板堆石坝的坝轴线下游至坝脚之间设置基础排水结构，所述基础排水结构包括设置在堆石体以及弃渣填筑体下方的排水箱涵。本发明通过利用排水箱涵做为大坝的基础排水结构和增设下游弃渣体双重措施使工程开挖初期的弃渣、次堆石料具备填筑的条件，减少弃渣场和中转料场的设置，有利于缓解地表土石方工程对环境的破坏。
