More information on Access Chambers and Duct Boxes:

Duct boxes permit you to build an access / linking chamber point for all types of underground ducting. They're each 335mm high and may be stacked to give your custom depth. The sides are a part cut for an assortment of ducting sizes. A manhole cover is necessary for the top of the chamber.

Composite covers and frames available to suit.

Access chambers permit entry to underground utility services such as telecoms, electric and fibre optics. These chambers have pre-formed holes to allow you to cut sections out to suit the ducting and allow structure.

Duct boxes or access chambers are made from HDPE and provided with semi cut holes to allow the installer to finish the cut and insert the compatible sized duct pipe. Entry points suit 63mm, 160mm, 110mm & twinwall duct.

An inspection chamber is sectional and typically is made up of foundation, sectional risers with a seal, and a manhole cover on your desired finish. The risers sit along with the base and the joint is sealed using an rubber seal.

Subsequent risers may also be added to give additional height and sealed using an integral rubber seal again. Framework and the cover sit on top of the risers at floor level.

An access chamber is constructed to facilitate easy access to an underground network facility most of the times being a twinwall ducting system. Access chambers and covers are usually a necessity for any underground twinwall ducting installation and are essential for completing any ducting system.

Telecommunication companies are opting to use underground systems to run their vast network of cables from point A to B. An access chamber is, therefore, a must have facility to enable access to the cables for troubleshooting amongst other operations.

While working on pipe systems, drainage engineers can deliberately block a pipe and use the manhole in precisely the identical way, to store waste water before allowing it to flow away once the drainage task is complete. As well as giving access to drains and sewers, chambers are an important temporary storage point for water.

They allow water to build up in the drainage system instead of flooding out straight away. A manhole, or access chamber is an access point to an underground utility network, including a drainage system.

A drain or sewer manhole's presence allows the pipes to be inspected, surveyed, unblocked, cleaned, or repaired. Building Regulations govern in the UK guidance on the design, location, and arrangement of inspection and manhole chambers. Manhole covers can be made from other materials, including concrete, steel, and also recycled vinyl. They can also be different shapes, including square, triangular, round, and rectangular.

What are access chambers used for?

  • They are essential for security, as they prevent people from falling down the manhole or seeking to enter the drainage system without any consent.
  • Manhole covers also prevent things and debris from getting into the drainage system in which it might cause a blockage.
  • They also prevent surface water from getting into the drainage system at the point, so the drainage pipes don't become overfull during heavy rain.

While working on pipe systems, drainage engineers may block a pipe and apply the access chamber in precisely the identical way, to store waste water before allowing it to flow away after the drainage task is complete. Manhole chambers are an important temporary storage point for water In addition to providing access to drains and sewers. They allow water to build up in the drainage system instead of flooding out straight away.

Increasingly, manholes are being replaced or augmented with remote access drainage points called "rodding points". Cheaper to set up, these are smaller than manhole chambers. Rather than allowing a person to get down to the drain, they offer access for a drain rod, a water jetting hose, or a CCTV drainage survey camera, to assist in the process of inspecting, cleaning, or unblocking a drain pipe. CCTV drainage polls and drain water heaters could be carried out via a manhole room.

Access Chamber Safety

Without having to enter them is greatest strategy, inspecting, cleaning, and fixing drains. This is only because manhole chambers present a health and safety threat. Additionally, oxygen levels can drop in ones that are especially deeper, and poisonous gases can also build up. In both situations, a person entering a manhole chamber can quickly become unconscious and die as a result of lack of toxic gas poisoning or lack of oxygen.

The alternative to using remote access equipment to operate on a drainage system via a manhole chamber is by carrying out a confined space entry. This involves using a process that is careful, involving a group of drainage operatives, using specific safety clothing and gear, to enter the manhole room safely. Members of the general public and trades people who aren't trained in confined space entry are strongly advised not to enter a chamber due to these factors.

There might not be a manhole in a location required to conduct a drainage inspection, clean a sewer, or unblock a drain. This may be attributed to oversight when the drainage system was placed in, or since the drainage system has not been upgraded to cope with subsequent developments. Where this happens, it can be essential to create a manhole to add access to this pipe.

A manhole room may become buried or built over, either intentionally or by mistake. The manhole is going to have to be excavated to get access to a specific stage in the drain, if needed. Or a brand new drain access point will have to be created in another location.

The manhole may become unstable due to the corrosion of these materials it is made from -- or due to ground movement, or action from tree roots. In cases like this the manhole might have to be fixed or replaced.

Manhole covers may become loose, broken, or lost. This will create a safety hazard and will allow debris and excess water (during periods of heavy rain) to enter the room.
