The rain sluice is an indispensable public facility on the roads of modern
cities. Its main role is known to all of us. It is the main channel for entering
the underground pipelines or underground pipelines. It must also be resistant to
roads when not in use. Pressure capacity and aesthetics are also very good for
protecting the safety of underground pipelines and pedestrians.
In the current market, there are many materials for manhole cover, but if it is the most widely used rain gown, what advantage does it have over other material covers? It is a type that is often used, but it has iron elements inside, and the cover is exposed on the road, wind, sun and rain. The long time causes corrosion to iron, which seriously affects its use. The effect does not guarantee its safety on the road. Secondly, compared with the cement manhole cover, it avoids the problem of corrosion, but its volume is relatively heavy and the construction time is long. In addition, it does not connect well with the road surface, and often it is higher than the earth's surface, causing bad influence on the passage of pedestrians. Its color is also poor in appearance, and the rain scorpion as a new material, both in hardness and corrosion resistance have a good performance, in addition to its round design, make the road more secure, and road convergence Closer.
