A1260 Bridge Structures Project

Below are details of one of our projects, we have further examples of our other projects to come!

The work on the A1260 was carried out for Osborne and completed by the end of March 2011. The challenge was to remove 245m³ from 12 piers in the shortest time possible. Due to the nature of the project we were competing with different methods of removal at tender stage and we had to ensure that our proposals were both cost effective and able to meet the demands of the programme.

On each pier there was 20.46m³ to be removed and we set ourselves the timeframe of 4 No 24hr periods to complete this. This meant operating with two crews during the day and two crews during the night.

Unfortunately there was no water supply available at any of the piers, which would have been a major problem had we not been able to use our tanker units to both jet with and as static tanks. We then arranged for a local contractor, IWJS, to collect and deliver water into our tanks throughout the day and night shifts to allow us to jet continuously for 20hrs per day, only stopping to allow clear up of the huge volumes of concrete being removed.

During the first phase of 6 piers we encountered a few teething problems similar to any that occur on a project of this magnitude. We also had to work through freezing conditions with temperatures dropping to minus 14 on site, which is obviously not ideal for water jetting. Despite the difficulties we were able to complete the first phase on programme and leave Osborne extremely satisfied with our performance.

When the second phase began we knew that we would be able to comfortably meet the programme and we therefore reduced the number of jetting crews to three. We also managed to reduce the time taken to complete each pier to 3 No 24hr periods as the freezing weather had subsided and everybody on site knew what was required for the job. The second phase was completed successfully over a 5 week period.

Water Jet Concrete Cutting

One of the reasons for the popularity of water jet concrete cutting is that it meets even the strict environmental laws. It generates little dust due to the use of water, as there is no metal edge to sharpen, and no heat or spark generated during cutting. There are also no finishing steps required as the cut produced by the water jet is perfectly fine.  The forces involved make the use of water jet cutting with robotics possible.

Water Jetting

Water jetting involves pressurizing water to mega high pressures which then form an intense cutting stream To achieve these pressures, water is introduced into the unit via a booster pump and filter visit us online to find out more about water jetting and the water jetting services we provide please visit us online at http://www.sabrejetting.co.uk/

Sabre Jetting Services Ltd - Ready for London

Sabre Jetting Services are ready to meet the new Low Emission Zone standards which came in to force in London on 1st January 2012. We currently have both Euro 4 and Euro 5 tanker based hydro-demolition units and have built two Euro 4 van based hydro-demolition units which were ready before the new legislation came into effect.

Sabre Jetting Services are committed to utilising the latest technology to enhance the performance of our equipment and to reduce our carbon footprint. As well as four LEZ compliant vehicles we will also be introducing our fourth ‘Stage Three’ static engine to the fleet. These engines are electronically controlled and thus able to regulate emissions automatically.
Our dedication to continuously improve our equipment has also meant a superior service for our clients, who are benefitting from shorter programmes and lower costs, due to our outstanding reliability and production. Consequently, Sabre Jetting Services are the number one choice for hydro-demolition from both an environmental and strategic perspective.

More About Water Jet Concrete Cutting

The water jet used for water jet concrete cutting contains abrasive particles and travels at up to 750 metres per second. The abrasive acts to erode the material it is focused at in a similar manner to saw cuts, but on a smaller scale. To find out more visit us at http://www.sabrejetting.co.uk/

Water Jet Concrete Cutting

A technique of cutting concrete that uses no heat or spark is to use a water jet. Water jet concrete cutting uses compressed water that travels at twice the speed of sound to cut through concrete. The water used is at a high pressure, over 25,000 psi. This allows precise control over the cutting, resulting in the creation of complex shapes.
