一种块石混凝土堰坝加固结构
By setting curtain grouting holes, concrete anti-seepage panels, and new riprap slope protection in the riprap concrete weir, filling the replacement trench with cement mortar and small stones, and configuring steel mesh and wave walls, the problems of uneven stress and crack propagation in the weir structure were solved, thus achieving the stability of the weir and the protection of the ecosystem.

Abstract
Claims
1. A rubble concrete weir reinforcement structure comprising a primary rubble concrete weir body (1), characterised in that: One side of the original riprap concrete weir (1) is provided with a backwater surface (3), and the other side of the original riprap concrete weir (1) is provided with a frontwater surface (4). Multiple curtain grouting holes (16) are opened on the outer walls of both the backwater surface (3) and the frontwater surface (4). Multiple consolidation grouting holes (15) are opened on the outer walls of both the backwater surface (3) and the frontwater surface (4). A concrete anti-seepage panel (5) is fixedly connected to the outer wall of the frontwater surface (4). A geotextile (7) is fixedly connected to the top surface of the concrete anti-seepage panel (5). A new riprap slope protection (8) is fixedly connected to the top surface of the geotextile (7). A riprap concrete replacement structure (2) is provided on the outer wall of the original riprap concrete weir (1). The riprap concrete replacement structure (2) is used to replace the parts of the original riprap concrete weir (1) that have quality problems.
2. A block stone concrete weir and dam reinforcement structure as claimed in claim 1 wherein: The rubble concrete replacement structure (2) includes a replacement groove (201), which is opened on the outer wall of the original rubble concrete weir (1). Cement mortar (202) is provided at the bottom of the replacement groove (201), small rubble stones (203) are provided at the top of the cement mortar (202), and high-hardness concrete (204) is provided at the top of the small rubble stones (203).
3. A block stone concrete weir and dam reinforcement structure as claimed in claim 1, wherein: The top surface of the original riprap concrete weir (1) is provided with a widened dam crest (13), and the interior of the widened dam crest (13) is provided with a steel mesh (14).
4. A block stone concrete weir and dam reinforcement structure as claimed in claim 1, wherein: The concrete anti-seepage panel (5) is provided with a multi-layer steel mesh (6) inside, and a rubber waterstop (9) is fixedly connected between two adjacent concrete anti-seepage panels (5).
5. A block stone concrete weir and dam reinforcement structure as claimed in claim 1, wherein: The original boulder concrete weir (1) is fixedly connected with a connecting bar (10), and the other end of the connecting bar (10) is fixedly connected to the concrete anti-seepage panel (5).
6. A block stone concrete weir and dam reinforcement structure as claimed in claim 1, wherein: A wave-breaking wall (11) is fixedly connected to the outer wall of the water-facing side (4), and a railing (12) is fixedly connected to the top of the wave-breaking wall (11).
7. A block stone concrete weir and dam reinforcement structure as claimed in claim 1, wherein: The outer wall of the backwater side (3) is provided with a concrete frame slope protection (17), and vegetation protection is carried out inside the concrete frame slope protection (17).
8. A block stone concrete weir and dam reinforcement structure as claimed in claim 1, wherein: The outer wall of the new riprap slope protection (8) is provided with graduations, and the outer wall of the new riprap slope protection (8) is provided with a biological film board.
