In the parking lot renovation project of Taizhou Railway Station, the matching design of square floor tiles and drainage outlets has become a key element in ensuring safe passage during rainy weather. The components equipped with these drainage outlets, also known as "rainwater grates", are grid - shaped cover plates for collecting rainwater on the ground. They can not only efficiently channel rainwater to avoid water accumulation on the ground affecting the driving of vehicles and the walking of pedestrians, and reduce safety hazards such as slips and vehicle skids caused by water accumulation, but also effectively block debris such as fallen leaves and gravel from entering the pipeline with their grid structure to prevent blockage of the drainage system. In the project of Taizhou Railway Station, a total of 200 rainwater grates were ordered, all of which are of the 450*300mm model. This uniform specification is not only convenient for construction and installation, ensuring that the layout of drainage outlets and floor tiles is coordinated and beautiful, but also can quickly drain rainwater through standardized drainage capacity when the rainfall is large, providing a solid guarantee for the safe and smooth operation of the parking lot of the railway station, so that passengers and vehicles can pass safely even on rainy days.
