Notice update – Sheet piling Washwood Heath Brook diversion August 2022 | www.hs2.org.uk

What we are doing

We previously notified you that we will need to install sheet piles to divert a section of the Washwood Heath Brook that runs through the site in underground pipes known as a culvert into the River Thame. We have paused these works throughout August and are preparing to start installation, week commencing 12 September 2022. We anticipate works to be completed by the end September 2022.

We will be installing sheet piles into the ground to a maximum depth of 16 meters. To install the sheet piles, we will need to locate the piling plant platform on the east side of the Brook near to Drews Lane. We will minimise the use of plant machinery to reduce deliveries to the working area.

We have already completed a large section of the sheets piles and will be working further away from residential properties. To reduce the vibration and noise from our work we will be using a technique known as pre-augering. This is a method where the pre augering loosens the soil at the location of the sheet piles, pre pierces and loosen the ground to make it easier to install the sheet piles. This helps to prevent much of the resistance on the sheet pile as they are vibrated into place, therefore reducing the overall levels of vibration and noise associated with the works.
