Residential Area And Courtyard

In the drainage improvement project of the old urban area, the upgrading of drainage outlets at the edges of residential roads and green belts has become a key link in enhancing the regional drainage efficiency. The facilities adopted for these drainage outlets are the so - called "rainwater grates" — grid - shaped ground cover plates. They fit closely with the layout characteristics of roads and green spaces in the old urban area and take on a dual mission. On one hand, they can quickly collect surface rainwater and efficiently channel water flow through their grid structure, ensuring that the roads stay dry without water accumulation and that the vegetation in the green belts is protected from waterlogging damage. On the other hand, they can block debris such as fallen leaves and sediment with their dense grids, preventing pipeline blockages at the source and ensuring the smooth operation of the drainage system. For this renovation, 300 rainwater grates of uniform specification were specifically ordered, all of the 450*300mm model. This standardized size precisely fits the narrow road edges and green belt boundaries in the old urban area. It not only facilitates construction and installation, ensuring seamless integration with the surrounding environment, but also forms a coherent drainage network through batch deployment. Like 300 invisible "guardians", these rainwater grates are evenly distributed across residential areas. They not only enhance the local drainage capacity but also work in synergy with the overall improvement project, making the drainage system of the old urban area better adapt to rainy weather. This creates a dry and clean living environment for residents and allows the vegetation in street green spaces to become more lush with proper water regulation.
