Concrete panel structure applied to high-toe wall and construction method

Abstract

The invention relates to a concrete panel structure applied to a high-toe wall and a construction method, in order to improve stress and deformation conditions of a toe board and the overall stability of a panel, thereby improving the operation safety and reliability of a project. The concrete panel structure is characterized in that the concrete panel structure applied to the high-toe wall is provided with a concrete panel, toe boards arranged at the periphery of the concrete panel, and a rock-filled layer below the concrete panel; the toe boards arranged along a side slope of a mountain body is excavated to form a side surface slope with the gradient of 1:0.5; a balance weight type toe wall is arranged between the side surface slope and the concrete panel; a slope with the bottom extending outward is arranged on one side, close to the concrete panel, of the balance weight type toe wall; a balance weight platform is arranged on one side, close to the side surface slope, of the balance weight type toe wall; a groove of which the cross section is in an inverse-trapezoid shape is formed between the balance weight platform and the side surface slope; the groove is backfilled with rock ballast; the concrete panel is vertically connected with the balance weight type toe wall; and a water stop system is arranged in a connection seam formed by the concrete panel and the balance weight type toe wall.

Description

technical field [0001] The invention relates to a concrete panel structure using a high toe wall and a construction method. It is mainly applicable to similar projects in concrete face rockfill dam projects where the toe slab cannot be arranged smoothly due to geological and topographical conditions and other factors. Background technique [0002] In the concrete face rockfill dam project, the toe slab has higher requirements on the foundation. The "Code for Design of Concrete Face Rockfill Dams" (DL / T5016-2011) stipulates that the toe slab should be placed on a hard, non-erosive and groutable Weakly weathered, weakly unloaded onto fresh bedrock. However, in actual engineering, due to the influence of geological and topographical conditions, the excavation depth of the foundation in some areas of the plinth may be relatively large, so that the plinth at this part cannot be smoothly connected with the surrounding plinth; at the same time, the foundation surface of the plinth...
