During the manufacturing of drainage plastic molds, it is crucial to analyze specific issues individually, especially the water source conditions around our environment and the height of the groundwater level. If the water level is high, it is necessary to lower it, which ensures the subgrade remains dry and stable. Therefore, the use of concrete drainage channels brings significant positive implications. The structure of the drainage plastic mold is very simple, with a water passage in the middle. Due to its rectangular shape, it allows water to flow more gently, reducing impact force, thereby protecting the concrete channel. When collecting water, it is designed based on the road gradient, enabling quick concentration of water that falls on the road surface. This also improves the road environment, contributing to the beautification of the urban landscape.
