ECI on new and bespoke contracts via USL TEKSERV.
With more complex and substantial machining demands for projects, Ekspan now operate a state-of-the-art Hurco DCX3226i CNC machine, an essential addition to their in-house manufacturing facilities.
USL Ekspan is the UK's largest quality bearing supplier and installer to meet demands both in the UK and worldwide.
USL Ekspan install an extensive range of mechanical and elastomeric expansion joints and seal joints to CD358 standards.
Bridge jacking and temporary works are an essential part of most bearing replacement and refurbishment operations, ensuring works are carried out safely and efficiently without affecting the integrity of the structure.
The importance of carrying out bearing and expansion joint inspections by proficient and competent engineers who understand their functionality can often be key to maximising a structure’s lifespan and avoiding major, unexpected, emergency repair costs.
USL Ekspan have carried out a number of projects for swing bridges and foot bridges. From design, fabrication of all structural components, to trial erection and final installation. Details of these type of bridge installations can be supplied on request.
The existing bridge expansion joints had come to the end of their life span and were to be replaced with a Modular expansion joint. USL Ekspan's Britflex BEJ expansion joint was the client's preferred choice and was specified by Jacobs as the ideal replacement joint. There were eight joints to be replaced in total, seven of which utilised Britflex BEJ 5 (50mm movement) expansion joints measuring 26.60 metres and one using Britflex BEJ 10 (100mm movement) expansion joint, also 26.60 metres in length.
The works were to be undertaken at night from 21:30 to 05:30 under lane closures, using four joint installation crews over a period of eight nights. The completed works had to be cured in time to accept traffic the following morning.
One expansion joint to the North Abutment (nearest Big Ben) had to be completed under a full road closure on a single Sunday night utilising three joint installation crews due to the complexity of the road layout at that end of the structure.
Pedestrians had to be given access to cross over the structure 24 hours a day, so safeguarding the public from USL Ekspan's works was of major importance.
The Britflex BEJ expansion joint was chosen because of the quick installation of this cost-effective system. It allowed minimal disruption to the public, and the works could be completed in phases allowing public access to the bridge at all times.
By undertaking the works in phases, traffic still had access to use the structure to cross the River Thames, excepting just one night when a full road closure was in place.
USL Ekspan's Britflex BEJ expansion joint system has been extensively used by Transport for London for in excess of 25 years. It has been installed on some of the UK's most prestigious structures, including Tower Bridge, London Bridge and Waterloo Bridge, to name a few, and is seen by the client as the ideal solution when Type 6 expansion joints need replacing on its structures.
