Science Popularization Revelation: Exploring the Differences and Diverse Styles between "Water Grates" and "Rainwater Wells"

As the Start of Autumn approaches quietly, Chengdu has witnessed its first autumn rain of the year. In this natural baptism, the "water grates" of the city have demonstrated their unique functions - guiding water flow and blocking debris, contributing their own strength to the city's drainage system. However, for such an indispensable urban facility in daily life, what exactly is the "water grate"? What are the differences between it and stormwater inlets, stormwater Wells and inspection Wells? Meanwhile, how ingenious and diverse are the styles of "water grates" in different regions? Next, let's explore the answers to these questions together.
The water grate, also known as the rainwater grate, is carefully welded with flat steel and twisted square steel, or welded with a combination of flat steel and flat steel, presenting a beautiful and elegant appearance. Its design is ingenious. It not only has excellent drainage capacity, but also features high strength, diverse specifications and high cost-effectiveness. Therefore, it is widely used in urban drainage systems. In recent years, with the continuous advancement of technology, new types of composite water grates have emerged. These water grates are made of resin or plastic as the base material, reinforced with steel bars, and added with inorganic fillers, thus forming unique and comprehensive performance. Its self-weight is lighter than that of traditional cast iron water grates, and its cost is more affordable. However, its strength is slightly inferior to that of cast iron water grates, providing a new option for urban drainage systems.

Rainwater inlets, as an important component of the pipeline drainage system, are mainly responsible for collecting surface water. It is carefully composed of several parts such as the inlet water 篅, the well body and the branch pipe. The common types include the side-channel type, the flat type and the combined type.
The rainwater well has holes on its side that are connected to the drainage pipe, and at the bottom, it is equipped with a downward extending seepage pipe. This design can not only introduce rainwater underground for replenishment, but also ensure that the excess rainwater is smoothly discharged through drainage pipes, thereby effectively alleviating the problem of ground subsidence and preventing the road surface from being submerged by water during heavy rain. In addition, the rainwater well is equipped with a basket to intercept dirt and prevent it from clogging the drainage pipes. It also facilitates daily cleaning work.
Inspection Wells, a kind of well-shaped structure, are usually made of plastic through one-piece injection molding or brick masonry. They are specially designed for the drainage systems of residential areas, public building areas, factory areas, etc. Its outer diameter is suitable for buried plastic drainage pipes, with a maximum of no more than 800mm, and the burial depth does not exceed 6m. Inspection Wells are generally located at key positions such as the intersections, turns, changes in pipe diameter or slope, and drops of drainage pipes. They aim to facilitate regular inspection, cleaning and unblocking work, and at the same time provide convenience for downhole operations.
Diversified designs of water grates
Water grates, as an important component of the drainage system, come in a wide variety of design styles, each with its own unique features. These water grates not only carry out the important function of drainage, but also are a beautiful sight in the urban landscape. From traditional grille styles to modern innovative designs, each type of water grate showcases the designer's ingenuity, adding a unique charm to the city's drainage system.
