| description | The present invention discloses a seepage control and reinforcement process for small reservoirs, which specifically includes the following steps: Step 1: Clay backfill; Step 2: Concrete pouring; Step 3: Compaction grouting; Step 4: Stone pitching. The present invention employs clay replacement on the upstream leaky dam slope to reinforce the dam's anti-seepage capability. By strictly layering and rolling backfilled clay, contact leakage between the right wing wall of the spillway and the dam body is prevented. A new reinforced concrete anti-seepage wall is used on the upstream side of the spillway to cut off the leakage channel beneath the spillway slab. Compaction grouting is carried out below the crest of the spillway to fill any potential voids beneath the slab. Stone pitching is applied to the energy dissipation pool of the spillway and the connecting section of the downstream river to prevent adverse effects onthe safety of the spillway due to scouring of the downstream river during spillway discharge. |
