Horizontal joint seam connecting structure suitable for thin panel extrusion deformation

Abstract

The invention provides a horizontal joint seam connecting structure suitable for thin panel extrusion deformation. The horizontal joint seam connecting structure comprises concrete panels, steel sleeves, reinforcing steel bars, a gap filling material, a water stop copper sheet, a surface water stop structure, asphalt jute and a horizontal seam, wherein the concrete panels are arranged in an inclined mode, and the horizontal seam is transversely formed between adjacent two concrete panels; the reinforcing steel bars pass through the horizontal seam for connecting adjacent two concrete panels, and the gap filling material is arranged in the horizontal seam; the steel sleeves are arranged at the two sides of the horizontal seam and are positioned in the concrete panels; the reinforcing steelbars are positioned in the steel sleeves; the inner parts of the steel sleeves are filled with asphalt jute; the surface water stop structure is arranged on water face of the horizontal seam, and thewater stop copper sheet is arranged on the bottom of the horizontal seam. The horizontal joint seam connecting structure can remarkably reduce the possibility that the position near the horizontal seam is damaged as a result of thin panel extrusion while meeting anti-seepage requirements, and guarantees safe operation of the concrete panels in a high-concrete panel rock-fill dam.

Description

technical field [0001] The invention relates to the technical field of hydraulic dam engineering, in particular to a horizontal seam connection structure adapting to the extrusion deformation of thin panels. Background technique [0002] With the implementation of the hydropower strategy, a large number of high dams have been built, are under construction or are to be built in the southwest and northwest regions rich in hydropower resources. Earth-rock dam is the most common dam type in dam construction today, and it is also the fastest-growing dam type, mainly including homogeneous earth dam, core wall dam and concrete face rockfill dam. [0003] The face rockfill dam is a type of dam that uses the rockfill dam body as the supporting structure and sets a thin layer of concrete face on its upstream surface as an anti-seepage structure. In recent years, the technology of concrete-faced rock-fill dams has developed rapidly. Currently, the construction level of concrete-faced ...

Problems solved by technology

[0004] In order to overcome the problem that the existing thin panels near the horizontal joints are severely damaged and the steel bars are bent and deformed, the present invention provides a horizontal joint connection structure adapted to the extrusion deformation of the thin panels. The present invention sets steel sleeves at the horizontal joints, The asphalt hemp is filled in the steel casing so that the steel bar near the horizontal joint is separated from the concrete and can move relative to each other, and a rubber backing plate is installed at the bottom of the horizontal joint, and a water-stopping copper sheet is set on the rubber backing plate, and a surface water-stopping structure is adopted on the facing surface of the panel to block
