Rain sewage pipe network bionic silt reduction facility design method
The invention relates to the field of rainwater and sewage pipe network cleaning, in particular to a design method for a bionic silt reduction facility of a rainwater and sewage pipe network. The silt reduction facility comprises a plurality of sets of waved plates connected end to end, the waved plates are similar to complex wrinkled structures of dragonfly wings in shape, and the waved plates are integrally designed to be of a continuous waved structure consistent in shape and size and installed in the rain sewage pipeline in the water flow direction. The invention is inspired by the concave-convex structure on the surface of the dragonfly wing that the air velocity difference is generated above and below the wing, and is designed based on the complex wrinkle structure of the dragonfly wing. By installing the silt reduction facility in the pipeline, the hydraulic characteristic in the pipeline is optimized, the sedimentation and accumulation phenomena of particulate matter are reduced, the generation of pipeline deposits is fundamentally blocked, and the final target of long-acting silt reduction is achieved. As a facility for preventing pipeline siltation from the source, the device is suitable for being installed as a part of a pipeline in the early stage of construction of a drainage system. The silt reduction facility has the advantages that extra force does not need to be applied to the silt reduction facility, strong vortexes and shear flow can be passively induced as long as water flow flows through the wavy structure, and the deposition phenomenon of a rain and sewage pipe network is restrained from the source.
本发明涉及雨污管网清洁领域，尤其是涉及雨污管网仿生减淤设施设计方法。减淤设施包括若干组首尾相连的波浪板，波浪板形状类似于蜻蜓翅膀的复杂褶皱结构，整体设计为形状尺寸一致的连续波浪状结构，顺水流方向安装在雨污管道内。本发明受到蜻蜓翅膀表面凹凸结构使得翅膀上下方产生空气流速差的启发，基于蜻蜓翅膀复杂褶皱结构所设计。通过在管道中安装减淤设施，优化管道中的水力特性，减少了颗粒物沉降、堆积现象，从根本上阻断了管道淤积物的产生，达到长效减淤的最终目标。本发明作为一种从源头上防止管道淤积的设施，适合在排水系统建设初期作为管道的一部分进行安装。本发明优点在于这种减淤设施不需要施加额外的力，只需水流流经波浪状结构即可被动地诱导强漩涡和剪切流，从源头上抑制雨污管网淤积现象。
