Description

Technical Field

[0001] The utility model relates to the technical field of copper water-stopping protection, in particular to a copper water-stopping protection device for a concrete panel rockfill dam. Background Art

[0002] Concrete panel rockfill dam: A rockfill dam with a rockfill body as the supporting structure and a concrete panel as the anti-seepage structure on its upstream surface. Since such a large-scale project as a rockfill dam cannot be poured continuously, or due to foundation deformation, temperature changes and other reasons, the concrete components will expand and contract due to heat, thus causing leakage risks at construction joints, settlement joints, deformation joints and other parts. By adding water-stop copper sheets, these leakage channels can be effectively blocked to ensure the waterproof safety of the project; water-stop copper sheets can also prevent the bottom plate from breaking due to uneven sedimentation in water conservancy projects.

[0003] For example, the application number is 202220114026.9, a copper water stop protection device for a concrete panel rockfill dam. The device improves the protection of copper water stops around the concrete panel rockfill dam's perimeter seams and wave-breaking walls, ensures construction quality, and speeds up construction progress. The skeleton body used reduces the overall weight and the amount of angle iron used while ensuring effective protection.

[0004] It has the following disadvantages:

[0005] If the surface of the rockfill dam is not smooth enough, there will be a gap between the upper plate, the lower plate and the rockfill dam. During the construction of the rockfill dam, dust and overflowed concrete will fall onto the copper waterstop from the gap between the upper plate and the rockfill dam. The copper waterstop will be easily bent due to the accumulation of dust and concrete, which will affect its effect.

[0006] Therefore, we proposed a copper water-stopping protection device for concrete face rockfill dam to solve the above problems. Utility Model Content
