A construction shaped panel rockfill dam

By employing a sawtooth surface structure in the rockfill dam with contact between the serrated surface and the protrusions, combined with the friction of the impermeable liner, the stability of the panel is improved, solving the problem of insufficient stability when the bottom surface of the panel is in contact with the base alone.

AI Technical Summary

Technical Problem

In existing technologies, the bottom surface of the panel of a rockfill dam only contacts the base, resulting in poor stability.

Method used

The bottom surface of the panel with a sawtooth structure contacts the upwardly sloping protrusion, and the combination of the friction of the waterproof layer and the support of the protrusion improves the stability of the panel.

Benefits of technology

The serrated surface structure and the support of the protrusions enhance the stability of the panel on the water-facing side of the rockfill dam, solving the stability problem when the bottom surface of the panel is in contact with the base alone.

Abstract

The application discloses a construction forming panel rockfill dam, which comprises a panel rockfill dam construction structure for improving the stability of the panel. The panel rockfill dam construction structure comprises a rockfill dam body on the bottom of a reservoir bottom rock stratum, a base on the bottom of a water-facing surface of the rockfill dam body, and a surface layer transition layer, an anti-seepage cushion layer and a panel which are successively constructed from inside to outside on the water-facing surface of the rockfill dam body. The bottom surface of the panel is in contact with a convex part in a zigzag surface structure, the convex part can limit the panel, and the convex part can stably support the bottom surface of the panel, thereby improving the stability of the panel on the water-facing surface of the rockfill dam body and solving the problem of poor stability of the panel bottom surface which is only in contact with the base in the prior art.
