Manholes are a common feature of most urban areas. These chambers are necessary for underground utility systems such as sewers or drainage systems. They are essential parts of community infrastructure and are often sometimes by a paving company. According to the experts at Trenchless Technology Magazine, there are more than 18 million manholes in the United States today. Let's learn more about manholes and manhole construction.

Manhole Uses

Manholes serve distinct purposes within city infrastructure. These structures are used for inspection, cleaning, and removal of obstructions that might be present in a sewer line. Manholes can also be used in the joining of sewers as well as the changing of direction or alignment of sewers. Another important feature of manholes is that the perforated lids that cover the entrance allow for gases to escape. This type of underground ventilation is crucial to maintaining a healthy sewer system.

Manhole Construction

There are various materials available when manholes are being constructed, so it's essential to ask your paving company what kind of materials are available and what the process will be like. If your manhole is beginning to develop cracks, a reliable team can provide leveling without needing to remove it. Your chosen team should also be able to answer any questions you may have about manhole construction.

Types of Manholes

In addition to different materials, there are also different types of manholes for different purposes. A shallow manhole is often used at the start of a branch sewer or in an area that doesn't see much traffic. Normal manholes are put within the sewer line and have a heavy cover. These are often square in shape. The third type is known as a deep manhole. These are used for deep access points.

Manhole Locations

Manhole location is determined by how it will be used. Manholes are often located in three main areas. Sewer line changes are one area you might find this construction. They can also be found in areas where there will need to be a change in sewer size or alignment. Expect to also find manholes where a junction is formed by two or more sewer lines.

These are just a few main things you should know about manhole construction.
