How To Measure & Install Access Chambers

How To Measure & Install Access Chambers

Access Chambers

Installation Guide

Network access chamber sections are measured by the measurements inside of the chamber. Attention should also be paid to the external dimensions when deciding whether the network access chamber will fit into the area required.

Access Chamber Dimensions

Rapid & Easy Installation

Step 1: Arrange corner pieces and sidewalls to match the chamber clear opening dimensions. Ensure that the lip is on the outside of the chamber. The corner pieces should be all ‘left’ or all ‘right’ on each section and will alternate between the two as the chamber increases in depth.

Step 1

Step 2: Layout the first ring section of connect pieces to ensure you have the correct components.

Step 2

Step 3: Now connect the sections using the jointing peg, ensuring that the top of the peg is level with the top of the section.

Step 3

Step 4: Build the next section on top, using the alternative corner pieces. This will provide a ‘brick worked’ chamber ensuring any joints are not in a vertical line.

CUBIS ACCESS CHAMBERS

STAKKAbox™ chambers are significantly faster to install than conventional alternatives, with complete installations typically taking under one hour. This results in reduced costs for the installer and significant time saving. No specialist equipment or plant is required in order to install an access chamber and there is no need for specialist box builders. With flexible installation, Cubis access chambers can be adapted to suit on-site conditions with standard tools to build over existing networks.

Cubis Access Chambers & Cable Protection

Network Rail PADS Approved

The Cubis Systems Network Rail PADS approved access chamber and cable protection products ULTIMA access chambers and MULTIduct™ cable protection were specified by Amey Consulting on a recent Midland Mainline upgrade at Kettering Electrical Stabling.

Reduction in track possession and installation times were key factors in the products being selected to deliver the electrical containment and chamber access elements of this light maintenance and stabling facility.

800×800 and 1200×1200 sized ULTIMA Chambers and approximately 700m of 4 Way XL MULTIduct™ were used on this part of the project and installed mainly along the four walkways between the tracks of the sidings.

The versatility of the modular ULTIMA sections was fully utilized on site, building up the levels of the chambers in segments to get to the correct height. This was found to be a much easier installation process than traditional build options given that the stabling facility was created by excavating down in excess of 2m from ground level to sub track formation.

Space is also at a premium when operating at trackside and the use of MULTIduct™ created significant installation space and time savings over regular circular ducting due to the compact profile.

The Cubis team helped from design phase to final installation advice, to ensure another successful rail project.

Stokbord Drum | Protection of High Voltage Electricity Cables

Stokbord Drum

Protection of High Voltage Electricity Cables

Representatives from across the utilities sector were shown first-hand how new developments in cable protection have made a significant step forward.

Centriforce, working through their distributor network including Thorne & Derrick, announce a new cable protection product that can help to improve working safety for High Voltage Electricity Cables applications – known as the Stokbord Drum.

The utility sector have been shown first hand how new developments in high voltage cable protection have improved performance, capacity and sustainability

Centriforce, manufacturers of the Stokbord Cable Cover and Stokbord Drum Systems, have developed a revised specification in accordance with The National Grid Standard TS 3.05.07, ENA-TS 12-23 Class 1 and ENA-TS 12-23 Class 2 technical specifications: which takes the thickness from 14mm and 12mm, to 12mm and 10mm.

Simon Carroll, Centriforce CEO, said: “The focus on the day was to demonstrate how Centriforce Stokbord Cable Cover and Stokbord Drum are capable of meeting technical specifications – delivering consistent protection with the benefits of 12mm for The National Grid Standard TS 3.05.07 and ENA-TS 12-23 Class 1 and 10mm for ENA-TS 12-23 Class 2.

“Traditionally, it has been considered industry practice to refer to 14mm protection for The National Grid Standard TS 3.05.07 and ENA-TS 12-23 Class 1, and 12mm for ENA-TS 12-23 Class 2 technical specifications.

“We were involved in those initial specifications, but materials science has moved forward, and the strength and performance of Stokbord now means that the utilities industry can draw on our research and development activity to achieve optimum safety with these new levels.

“This advancement makes a strong economic case for our utilities clients – ensuring that the Stokbord solution continues to be the optimum choice where safety and security count – whilst offering cost savings and sustainability benefits as standard.

“That brings a variety of advantages, including the reduced labour and transportation costs all associated with the introduction of lighter materials.”

Stokbord is a highly versatile impact resistant product that protects underground utilities from damage and at the same time provides a highly visual alert of what lies beneath.

For the utilities sector, it is provided as a cable cover, which is a one metre tile, or in the new drum format – launched last year – which offers a faster and safer solution to installation.

Both systems can used to protect underground utilities, particularly high voltage electricity cables, but can also be used for water and gas pipes, as well as fibre optic cables.

They help to prevent damage to cables buried underground by ensuring that anyone digging in the area at some point in the future, where a cable is laid, hits the Stokbord before they hit the cable – preventing serious injury, as well as a costly and disruptive outage in the electricity system.

Simon added: “For decades, we have been recognised across the industry for our time-proven and trusted methods of keeping underground utilities safe.

“Stokbord is specified around the world for its ability to deliver heavy duty protection for buried utilities, including gas, water, electricity and telecoms.

“It’s built a reputation based on trust. We’ve been the ‘go to’ partner in utilities for more than 40 years, standing out as pioneers in the sector and seen as the experts in knowing what we are doing.

“That expertise and industry knowledge means we are now well-placed to deliver new levels of performance with 12mm and 10mm standards, for 2020 and beyond.”

As part of the event, the visitors to Centriforce were able to witness an on-site impact test by an independent consultant engineer, to see first-hand the impact resistance and specification capabilities at the reduced thicknesses.

Attendees also saw a demonstration of the Stokbord Drum system, where Stokbord supplied on a reel enables it to be rolled across a large area with minimal intervention.

Jonathan Pearce, Head of Sales at Centriforce, said: “The drum system was developed in our work with our customers, who recognised that the amount of time spent in the trench was a rising concern.

“We focused on creating a mechanical rather than manual installation, keeping operatives safer and at the same time significantly speeding up the process.

“It reduces the manual labour involved and creates a lower risk environment as operatives spend less time in the trench.

“With this system and Stokbord Cable Cover, there is now a choice to meet exact project needs.”
