Ecological composite hard drainage channel

The utility model discloses an ecological composite hard drainage channel, which relates to the technical field of environmental protection and comprises two ecological permeable dams which are correspondingly arranged, and each ecological permeable dam is provided with a biological crawling corridor. The ecological composite hard drainage channel provided by the utility model can provide a migration escape channel for organisms, protect the ecological natural environment, prolong the hydraulic retention time of surface runoff, and greatly reduce the migration of non-point source pollutants to the downstream. 本实用新型公开了一种生态复合型硬质排水渠，涉及环境保护技术领域，包括对应设置的两条生态透水坝，各生态透水坝上均设置有生物爬行廊道。本实用新型提供的生态复合型硬质排水渠能够为生物提供迁徙逃生通道，保护生态自然环境，同时能够延长地表径流的水力停留时间，大幅度降低面源污染物向下游的迁移。
