Manhole cover
A manhole cover is a closed structure at the top of the entrance and exit to underground facilities. It is necessary to install manhole covers in places where public facilities such as tap water, telecommunications, electricity, gas, heating, fire protection, and sanitation are installed. With the rapid development of China's economy, China's infrastructure construction has entered a new cycle, and the market demand for manhole covers in urban planning and road construction is huge. However, damage to manhole covers caused by crushing often occurs, leading to a decrease in the safety of roads and facilities. This article starts with various manhole cover standards and analyzes the rationality of standard settings.

product description
A manhole cover is a closed structure at the top of the entrance and exit to underground facilities. It is necessary to install manhole covers in places where public facilities such as tap water, telecommunications, electricity, gas, heating, fire protection, and sanitation are installed. With the rapid development of China's economy, China's infrastructure construction has entered a new cycle, and the market demand for manhole covers in urban planning and road construction is huge. However, damage to manhole covers caused by crushing often occurs, leading to a decrease in the safety of roads and facilities. This article starts with various manhole cover standards and analyzes the rationality of standard settings.
What are the types of manhole covers and their respective uses
The manhole cover is just an appearance, hidden beneath is a hidden project of municipal public infrastructure. And the manhole cover is the entrance to them.
The pipelines with manhole covers in cities are generally divided into types: water and sewage pipelines, power pipelines and cable trenches, municipal pipelines, and communication pipelines (telecommunications, mobile, China Unicom, radio and television, etc.).
First of all, let's talk about the water supply and drainage pipes. The tap water pipe (upper water) cannot be shared with other types of pipes, so a tap water manhole cover appears on the ground. Sewage cannot be shared with other types of pipelines, so there are more sewage manhole covers on the ground. If the city has implemented rainwater and sewage diversion, there will also be an additional specialized rainwater manhole cover. If there is centralized heating in the north, heating well covers will also appear on the ground.
Then there is the power pipeline. Electricity is generally relatively simple, just a type of manhole cover. However, in the vicinity of a substation, there is generally no need for a power well cover, and instead, a power cable trench is directly built, which means that each channel is covered with a rectangular cover.
Afterwards, there are municipal pipelines and communication pipelines. The interior of municipal pipelines is similar to communication pipelines, and they are basically communication lines. The difference from separate communication pipelines is that if there are municipal pipelines on site with sufficient internal space and permission for use, municipal pipelines can be used. And there is no need for various operators and public security traffic management units to construct duplicate pipe wells. The underground pipe gallery (common trench) in developed countries will be the development direction of municipal pipelines in the future. At the same time, I also hope to be the endpoint of the various manhole covers mentioned above.
