Drains for trains

DRAINS FOR TRAINS

Drains for trains are placed on reinforced concrete bridges. They consist of two parts, the lower part with a flange for the correct placement of the sealing membrane and the upper part with the grate on the overflow surface. The system has openings at the level of the membrane, to receive the rainwater accumulated at this level, while the grate has openings of such a diameter as to ensure maximum drainage without concrete entering, which could clog the pipes. The system is suitable for concrete pad of a thickness of d=300mm. With outlet DN 200.
