Permeable Manhole Cover

Turbine manhole cover is a new type of urban drainage system component, mainly used to improve the flow capacity and drainage efficiency of rainwater, thereby effectively alleviating urban waterlogging problems. It has the following significant features and uses: 1. Large drainage capacity: The design of the turbine manhole cover can quickly form a vortex flow of water, accelerate the flow velocity of water, and thus increase the drainage capacity. 2. Not easy to block: Compared with traditional flat structure manhole covers, turbine manhole covers can effectively separate debris in the water flow, such as branches, leaves, tissues, plastic bags, etc., to prevent them from blocking the manhole cover.

At the same time, it is fixed with a reverse buckle to prevent bouncing and reduce the safety hazard of falling caused by human opening of the manhole cover.

Easy maintenance: The turbine manhole cover only requires regular or irregular cleaning of the garbage at the rainwater inlet, reducing pipeline accumulation and maintenance, and lowering the workload of municipal personnel 5. Aesthetics: The appearance of the turbine manhole cover is turbine shaped, simple and beautiful, and can maintain the integrity of the road surface. 6. Suitable for various environments: Turbine manhole covers are not only suitable for municipal road collection wells, but also for overflow wells, sedimentation wells, infiltration wells and other environments in rain gardens, grass ditches and wetlands.
