Panel structure of concrete panel rock-fill dam

Abstract

The invention provides a panel structure of a concrete panel rock-fill dam. The panel structure comprises panel units which are arranged on a stone dam body slope surface, wherein a gasket layer region and a transition layer region are sequentially laid between the panel units and the stone dam body slope surface from outside to inside; supporting piers are arranged between the panel units and dam body enrockment; rubber supporting bases are arranged among contact surfaces of the panel units and the supporting piers; and a water stop device is arranged between every two adjacent panel units. According to the panel structure provided by the invention, influences, on panel cracking failure, of uneven stress deformation of a dam body are effectively alleviated in a mode of transmitting force through the rubber supporting bases and bearing force through the supporting piers; the bottom surface of the concrete panel is pasted with carbon fiber cloth, so that strength of the panel is greatly improved, and permeability of the panel is reduced; water stop facilities of the panel structure are good in water stop effect; and a reinforced concrete face slab of the panel structure is prefabricated, so that project progress can be effectively quickened, and quality of the panel also can be guaranteed.

Description

technical field [0001] The patent of the invention belongs to the field of water conservancy and hydropower engineering, and in particular relates to a face structure of a concrete face rockfill dam. Background technique [0002] In recent years, a large number of high concrete face rockfill dams have been built at home and abroad, many of which are ultra-high concrete face rockfill dams of 200-300m level, such as the Shuibuya face rockfill dam in China and the Campos Novos face pile dam in Brazil. stone dam. At the same time of rapid development, the problems of cracking and leakage of the face of high concrete face rockfill dams due to extrusion damage have attracted people's attention. [0003] Although many projects have adopted the measures of adding stirrups to the panels and setting horizontal permanent joints to deal with the extrusion damage of the panels, there is a lack of necessary understanding of the mechanism of panel extrusion failure at home and abroad, and...

[0003] Although many projects have adopted the measures of adding stirrups to the panels and setting horizontal permanent joints to deal with the extrusion damage of the panels, there is a lack of necessary understanding of the mechanism of panel extrusion failure at home and abroad, and the problem of panel cracking and damage is still very serious
