Description

Technical Field

[0001] The utility model relates to the technical field of water area ecological restoration, in particular to a detachable filtering dam used for water area ecological restoration. Background Art

[0002] The main engineering measures for current river management projects are water ecological restoration. In the process of water ecological restoration and management, the control measures for the management of rivers and external rivers are particularly critical. The commonly used control measures include hydraulic dams, soft enclosures, various combined floating beds, etc. The dams are permanent hydraulic structures with high construction costs and require approval processes such as river demonstration. The control effects of soft enclosures and various combined floating beds are general, and they are difficult to adapt to the water level fluctuations of tidal rivers. Most river management projects adopt a point-to-surface promotion method. The detachable filter dam is a temporary facility with low construction costs. After the regional water quality is comprehensively improved, the filter dam can be disassembled as a whole without affecting the construction of the water network in the area. Under daily working conditions, the top of the detachable filter dam is higher than the normal water level. The external water enters the internal water body after being filtered by the infiltration module to realize the source water purification function. During flood discharge and waterlogging, the filter dam can be flexibly disassembled to the pre-drainage level to ensure waterlogging safety.
