The maximum lift undertaken was at a 75m radius.Initially full length 19.5m long sheet piles were installed using a Giken F201 ‘Silent Vibrationless’ Pile Press with this methodology being chosen to avoid any damage to the reservoir embankment clay core during the works.Once the exclusion zone was reached for working under the HV cables, then piles were pitched in 6.5m lengths and welded in-situ prior to driving using the Giken Pile Press.Further along the pile line where the cables sag between pylons, the available head height is even less meaning the piles were pitched in 5.0m lengths.In order to facilitate safe and effective movement along the remote and narrow embankment crest along with handling and pitching of the sheet piles under the HV cables exclusion zone; sheet Piling modified a 13Te excavator with a side grip articulating clamping system. * Bird News Pro and Bird News Ultimate subscribers receive full sighting details. Construction began in 1908 and the reservoir was opened in 1913 by King George V (hence the name).

Land south of William Girling Reservoir. William Girling Reservoir. This provided a safe and novel solution to the problem of distributing and pitching of sheet piles.All welding working was undertaken in accordance with Sheet Piling’s Welding and Inspection Quality Assurance Procedures including Weld Procedures, Welder Qualifications, Independent Weld Testing Protocols and Acceptance Criteria.A further innovation on the project was the implementation of a bespoke instrumentation device which allowed the inclination of the installed sheet pile to be measured upon completion to verify the specified installation tolerances had been achieved.

At the William Girling reservoir, we have been able to demonstrate our project management skills and solutions-driven approach, underlining our value as a sheet piling partner. If the current situation remained without any remedial works being undertaken, there is a significant risk of potential for instability of the reservoir embankment which would have catastrophic consequences.The main obstacle and hazard to installing 19.5m long Arcelor PU32 sheet piles through the existing central puddle clay core which is an integral part of the continuous earth embankment that enclosed the Basin; was the presence of 400kV high voltage overhead cables running across part of the embankment where the seepage was occurring.With that in mind, Sheet Piling (UK) Ltd proposed an innovative solution to overcome the additional problem posed by the overhead cables; on a project which was already problematical to install sheet piles though a puddle clay core in an operational reservoir.The solution involved pre-cutting the sheet piles into pre-defined lengths to allow them to be welded in-situ along the length of the puddle clay core whilst working until HV cables.Access to the extents of leakage through the clay core was also limited and as such, as solution involving lifting all plant and equipment onto the embankment using a Liebherr LR1600 600 Tonne Crawler Crane was developed. Sheet Piling (UK) Ltd have recently commenced works at William Girling Reservoir, North London where we are installing a sheet pile cut off wall through the existing reservoir clay earthwork embankment.Sheet Piling are working on the project for Costain Atkins Black \u0026 Veatch (CABV) JV and Thames Water in order to provide an impermeable cut off wall in an area where leakage through the reservoir core is currently ongoing.
