Problems solved by technology

Compared with ordinary toe boards, the thickness of the compressible rockfill under the toe wall is greater, and the variation is also greater. If it is not handled carefully, it will lead to large settlement and settlement differences under the surrounding joints, and then cause the surrounding joints to fail.

Abstract

The invention provides an anti-settlement structure connecting a spillway and a panel dam. The anti-settlement structure includes a panel dam, the spillway, and a water stop structure. The panel dam includes a rockfill material and a concrete panel; the spillway includes a side pier, and the side wall, near the concrete panel, of the side pier is successively provided with a maintenance step, a support step, a slope surface and a vertical surface from top to bottom; the water stop structure includes a metal impervious sheet and a plasticity filler; and the area between the concrete panel and the support step and close to the support step is filled with a first cushion material, the area between the concrete panel and the support step and away from the support step is filled with a second cushion material, the area below the concrete panel and close to the slope surface and the vertical surface is filled with the second cushion material, and the second cushion material and the rockfillmaterial are filled and connected by transition materials. According to the anti-settlement structure connecting the spillway and the panel dam, the settlement of the concrete plane relative to the side pier can be effectively limited, and the anti-seepage performance between the plane dam and the spillway can be further improved.

Description

technical field [0001] The invention relates to the field of engineering design of face dams, in particular to an anti-settlement structure connecting a spillway and a face dam. Background technique [0002] Concrete face rockfill dam (referred to as face dam) is a widely used local material dam type. In engineering practice, the spillway is often arranged adjacent to the dam. At this time, the guide wall, side pier and side wall of the spillway are often combined Make the toe wall of the panel dam. Compared with ordinary toe boards, the thickness of the compressible rockfill under the toe wall is greater, and the variation is also large. If it is not handled carefully, it will lead to large settlement and settlement differences under the surrounding joints, and then cause the surrounding joints to fail. . Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by the present invention is to prov...
