1results about How to "Reduce runoff velocity" patented technology

This invention provides a structure for flood control, aiming to address the challenges of impact damage, energy dissipation and deceleration, and smooth transition between mountain flood interception ditches and urban drainage systems. The invention mainly includes a cascading water system, a gradually widening section, an energy dissipation pool, a grating, a retaining wall, a slope toe, connecting pipes, ground level, inspection wells, and an energy dissipation sill. Through a three-stage energy dissipation system (cascading water system + energy dissipation pool + energy dissipation sill), the water flow velocity is significantly reduced. The grating intercepts debris and filters wastewater before it is channeled into the urban pipe network. A liquid level sensor triggers an alarm, providing sufficient emergency response time for wastewater treatment plants. This modular structure is suitable for narrow mountain sites, with a short construction period and high practicality.
