Concrete face for rockfill dam

Abstract

The invention discloses a concrete face for concrete face rockfill dam, which comprises costalia parts on two sides and a main board part arranged in the middle; each of the main board part and the costalia parts comprises an upper part, a middle part and a lower part which are all plane boards; the main board part and the costalia parts form an arced shape; the angles formed by the main board part and the costalia parts are 4 to 12 degree, and the two angles can be different; the main board part and the upper, the middle and the lower parts of the costalia parts also form an arc shape, and the included angles are 3 to 12 degrees; and the panel slits among the face plate units of the main board part and the costalia parts are fold-line type. Compared with the prior art, compression force is generated between the costalia parts and the rack around, so that the peripheral gap can not split; the face plate units in the invention are occluded with each other, so that the face plates are uneasy to conduct fault movement; and under long-term water effect, the peripheral gap and the splits of the face plates are combined together more firmly, and water seepage phenomenon is avoided.

Description

technical field [0001] The invention relates to the technical fields of civil engineering and water conservancy, in particular to a face plate for a concrete face rockfill dam. Background technique [0002] The dam section of the rockfill dam consists of concrete face, cushion material area, transition material area, main rockfill area, and downstream rockfill area from upstream to downstream. most important. The current concrete panel is a flat panel. When the panel is stressed as a whole, the panel will be squeezed or collided by water, and the panel will be deformed, so that the connection seam between the dam panel and the surrounding environment, that is, the peripheral seam, will be formed due to the deformation of the middle part.

Problems solved by technology

The current concrete panel is a flat panel. When the panel is stressed as a whole, the panel will be squeezed or collided by water, and the panel will be deformed, so that the connection seam between the dam panel and the surrounding environment, that is, the peripheral seam, will be formed due to the deformation of the middle. A pull with perimeter cracking, see Figure 9 , therefore, the peripheral joints of the dam are prone to cracking, resulting in leakage, landslides, and even damage to the dam body

At the same time, the joints between the several unit slabs that make up the dam face are also linear joints along the slope direction. Under the action of long-term water, the unit slabs are also prone to shift and open along the slope direction. Causes panel seams to crack from panel unit to panel unit, resulting in leaks
