The same logic also applies to the structure below the manhole cover:

The traditional term ‘manhole cover‘ is still widely used and understood. However, in the industry and formal settings, the increasingly accepted modern terms are “manhole covers” or “municipal utility manhole covers“.

Why did this change occur?

Abandoning ‘manholes’ is a global trend in civil engineering and public utilities, with the aim of using more inclusive, functional rather than gender based language. Emphasize its function (providing access for maintenance) rather than the people who use it.

Common new names and classifications:

1. Inspection Cover/Chamber Cover: This is one of the most direct and commonly used technical alternatives. It highlights its main purpose: allowing workers to inspect underground pipelines.

2. Utility Access Cover: This is a very accurate general term that clearly states that below it are public utilities (such as sewage, water supply, gas, electricity, communication, etc.).

3. Maintenance Hole Cover: Simply state that its function is for maintenance and repair
4. Drain Cover: Refers specifically to a manhole cover used for drainage systems.
5. Cable Cover: Refers specifically to a cover used for communication or power cable channels.

What is the name of the ‘well’ itself?

The same logic also applies to the structure below the manhole cover:：

Instead of ‘manhole’, it is now more commonly referred to as an Inspection Chamber, Utility Chamber, or Maintenance Hole.

Summary and Comparison:

Traditional Term	Modern/Preferred Term
Manhole Cover	Inspect manhole covers and municipal public manhole covers
Manhole	Inspection well, municipal well, pipeline well

 

It should be noted that the Chinese word “manhole cover” itself does not have a gender orientation, so in daily spoken language and many official contexts in China, “manhole cover” is still the absolute mainstream and completely acceptable term.

However, in engineering design, standard specifications, international projects, or more formal texts, you will increasingly see the use of more functional and professional terms such as “manhole covers”. The evolution of this term is mainly aimed at pursuing professional accuracy and international standards.
