VIP ready to talk TSG innovation at the WTC

WTC Conference and Exhibition

VIP-Polymers Ltd is taking its latest innovation in tunnel segment gaskets – a major step forward in cast-in gasket design – to the ITA-AITES World Tunnel Congress in Dubai.

The patented compliant compressible corner technology has already impressed clients on tunnelling projects. Now VIP will explain its benefits to delegates at the World Tunnel Congress (WTC), 21-26 April 2018.

VIP’s cast-in tunnel segment gasket (TSG), delivers consistent load performance along the entire perimeter of the gasket, greatly reducing risk of segment cracking during installation.

Matthew Levitt, VIP Technical Business Development Manager, said: “Our innovative cast-in gasket represents a step change in performance in terms of reducing segment cracking caused by corner point loading, which is one of risks tunnellers are most keen to eliminate during the installation process.

“We are looking forward to showing visitors to our stand at WTC how the technology works, and the advantage it delivers in terms of greatly reducing the need for post-installation repairs and associated costs.”

The gasket, created with a unique joining process that maintains the TSG profile right to the corner edge, has most recently been used in the construction of Scottish Water’s Shieldhall Tunnel under Glasgow.

Sam Simons, Tunnel Lining Supply Manager for Shieldhall joint venture construction partner Costain, said: “VIP gaskets contributed to an exceptionally well-built tunnel, with no reported segment cracking arising from high corner contact pressure, or segment ram loading transfer, cracks or leakage, meeting the tunnel lining specification without compromise.”

VIP can also point to recent contract success with two major tunnelling projects. It will provide its cast-in TSG for the 12.7km Thames Tideway Central wastewater tunnel in London. VIP is also supplying glued-in tunnel segment gaskets for the Mumbai Metro Line 3 (Packages 5 and 6), a 4.5km twin tunnel.

VIP is driving the development of innovative tunnelling products that deliver greater customer value. The compressible corner cast-in TSG is an example of how, by combining its in-house expertise in compounding rubber, product development and testing, and using enhanced manufacturing processes, VIP is supporting Contractors and Clients to achieve defect free construction.

Matthew Levitt said: “These are exciting times for VIP. There are always new challenges ahead. We’re attending WTC to talk to representatives from tunnelling companies and organisations across the world, to see how we can help them build better tunnels.”

VIP wins contract double for major tunnelling projects

VIP has won contracts to provide tunnel segment gaskets for two major tunnelling projects in the United Kingdom and India.

VIP has also won a contract to supply its latest cast-in gasket for the 12.7km Thames Tideway Central wastewater tunnel in London and has also won a contract to supply tunnel segment gaskets for a project to extend the Mumbai Metro.

Matthew Levitt, VIP Technical Business Development Manager, said: “Our success with both projects demonstrates our ability to deliver a wide range of innovative products and technologies for supporting major water and transport infrastructure projects anywhere in the world.

“These are exciting tunnelling projects that are vital to the sustainable development and growth of two great cities, and we’re delighted to be involved with them.”

Thames Tideway Central is the longest of three sections of a 25km tunnel, due for completion in 2024, designed to prevent the discharge of untreated storm water and sewerage from 34 combined sewer overflows into the tidal River Thames.

VIP is supplying its cast-in gasket referenced VIP028CI with patented corners to tunnel segment pre-caster Pacadar for the section, which will be 12.7km long, with an inner diameter of 7.8m. Supply commenced in December 2017.

VIP’s compliant compressible corner technology for cast-in gaskets delivers consistent load performance along the entire perimeter of the gasket. This eliminates the risk of high loads at one or more of the gasket’s corners during installation, which could contribute to segment cracking.

The technology has already been proven on other tunnelling projects, including the 5km Shieldhall wastewater tunnel in Glasgow, commissioned by Scottish Water.

This latest contract continues VIP’s long standing position as a major supplier of TSGs in India having previously supplied four phases of the Delhi Metro project and the Ghatkopar High Level Tunnel in Mumbai.

Matthew Levitt said: “The gasket has been specifically developed as a modification of our VIP024 gasket to provide additional sealing assurance sought by project engineers as the tunnel passes under the Mithi River.

Latest innovation in tunnel segment gaskets granted UK patent

VIP's Patented Corner Joint

VIP-Polymers Ltd has been awarded a UK patent for a cast-in rubber gasket corner joint system specifically designed to reduce the risk of tunnel segment cracking during installation.

The new ‘compliant compressible corner’ ensures delivery of consistent load performance along the entire perimeter of the tunnel segment gasket (TSG).

This eliminates the risk of a build-up of pressure at one or more of the gasket’s corners during installation, which could contribute to segment cracking.

VIP, based in Huntingdon, Cambridgeshire, is a global leader in the manufacture of rubber seals and gaskets for the tunnelling and water utility industries.

Steve Casey, VIP’s Sales and Technical Director, said: “We are delighted that the innovative design and manufacture of our new compressible corner joint, which is used across our entire cast-in gasket range, has been recognised with a UK patent. An international patent is also pending.

“Segment cracking during tunnelling operations is a significant cause for concern for both tunnel designers and tunnelling contractors. It is this concern we directly sought to address when we set out to design this new corner joint.

“Our innovation has been very favourably received within the tunnelling industry, and has already been used in a number of tunnel-building projects, with excellent results. VIP’s design has already been specified for use in future tunnelling projects.

“Tunnel segment cracking is a hidden cost in all tunnelling projects, through the need for post-installation repairs and other associated costs. By using our new corner joint, tunnelling companies can reduce the risk of TSGs contributing to these costs.”

Most cast-in TSGs are made with conventional ‘shot-joint’ corners. During the moulding process, the rubber in these corners fills the compression cavities in the extruded gasket sections, creating a solid rubber corner.

When the tunnel segments are installed, the compression of solid corners is very limited, which can result in corner point loading, thus increasing the risk of the segment becoming cracked.

VIP’s new patented corner joint is created with a unique joining process that maintains the TSG profile right to the corner edge. This makes the complete gasket compliant with all specified load requirements, which therefore provides greater assurance to designers, builders, and clients on the quality of the ring build.

These benefits have been demonstrated through rigorous comparative testing. This has shown solid corner joints are more resistant to closure, resulting in increasing loads, which could, potentially, affect closure between segments. In contrast, VIP’s new corner joint maintains a uniform closure performance around the whole TSG.

The new corner joint can also be manufactured at a variety of angles – 90 degrees, obtuse, and acute – so the TSG can be moulded to the exact shape and angle of each segment in the design. No tunnelling project is the same, however VIP can ensure a perfect fit, regardless of the shape of the segment.

VIP can also vary the profile orientation along the gasket’s Z axis. This can greatly help with the precise installation of final segments, or non-uniform segment systems, again reducing the risk of segment damage or partial sealing of joints.

Steve Casey said: “A multi-disciplinary team across our sales, laboratory, and product development departments has contributed to a new product that is now being used on international tunnelling projects, and is an innovation that can save the industry both time and money.

“Excellent test results we’ve witnessed, through to the positive feedback received from within the tunnelling industry, are testament to the hard work and collaborative effort put in by everyone at VIP.”
