Description

Technical Field

[0001] This utility model relates to the technical field of dam seepage drainage devices, and in particular to a flow guiding device and drainage system for dam seepage holes. Background Technology

[0002] In the field of hydropower, the structures used for hydropower dams can be categorized into gravity dams, arch dams, and earth-rock dams, based on a comprehensive consideration of factors such as topography, geological conditions, and hydraulic conditions. Earth-rock dams offer advantages such as low cost, simple construction, and readily available materials; however, compared to other dam structures, their impermeability and durability are relatively poor. In earth-rock dams, the seepage pressure effect caused by the difference in water levels between upstream and downstream inevitably causes water to flow through the dam body, foundation, and riverbed areas on both sides, resulting in seepage downstream. This process can easily induce various seepage hazards in the main dam structure and surrounding reservoir bank slopes, including but not limited to localized piping and soil erosion, thus threatening the overall structural integrity and operational stability of the dam.

[0003] To promptly drain seepage water from the dam body, seepage holes and diversion devices are typically installed inside the dam body. However, existing diversion devices for seepage holes usually consist of pre-embedded diversion pipes and fixed drainage pipes, forming a closed flow channel. Maintenance personnel find it difficult to directly and quickly observe the actual internal conditions, and often need to disassemble parts of the pipeline during maintenance, which is cumbersome and results in low maintenance efficiency and reliability. Utility Model Content
