▎ 摘　　要

NOVELTY - Anti-seepage structure of construction joint of rockfill concrete dam comprises multi-section dam body. The each section of the dam body is sequentially provided with upstream overburden layers (1), rockfill concrete layer (2) and downstream cover layer (3). The rockfill concrete layer is formed by layering rockfill and self-compacting concrete from bottom to top. The construction joint (4) is sequentially provided with first anti-seepage components from the upstream covering layer side to the downstream covering layer side, second anti-seepage component and the third anti-seepage component. The first anti-seepage component includes two embedded plates, two pressure plates and first water stop plate. The one of the embedded slabs is located in the lower rockfill concrete layer. An adjustment stud is installed in the threaded hole. The sealing ring is located in the construction joint. The sealing paste is fixed on the rockfill concrete layer by cement nails. USE - Used as anti-seepage structure of construction joint of rockfill concrete dam. ADVANTAGE - The structure: has excellent anti-seepage effect; and improves the durability of the anti-seepage component. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for construction method of anti-seepage structure for construction joint of rockfill concrete dam. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the anti-seepage structure of construction joint of rockfill concrete dam. Upstream overburden layers (1) Rockfill concrete layer (2) Downstream cover layer (3) Construction joint (4)
