The ‘silent’ piling technique – theory and local application, Cambridge

10 February, 2016 | 18:30 - 20:00

'Silent' piling technique that will mean less noise and vibration.

About this event

"Silent" piling is a relatively new technique to install sheet piles with minimal noise and vibration. The technique was developed in Japan by Giken Ltd and introduced in the UK in the 1990s.

The "silent" piler installs sheet piles by jacking them into the ground by a static force obtained by using the tensile capacity of previously installed piles and it is therefore limited in the installation force that can be provided.

The method works well in soft soils but can be more difficult in hard soils (e.g. dense sand) due to the large loads encountered during pile penetration. Part of the talk will explore a novel technique – "pile surging" - used to reduce ground penetration resistance during pile installation. Other possible techniques such as water jetting and rotary jacking will also be explained with their advantages and limitations.

The "silent" piler has been used locally in Cambridge for a number of projects in which Mott MacDonald acted as the Designer; the use and installation of these sheet piles will also be part of this talk.

Speaker

Francesca Burali d'Arezzo, Mott MacDonald

Francesca completed her PhD at Cambridge University in July 2015 on installation effects of sheet piles. Francesca's PhD work was entirely funded by Giken Ltd and focused on installation effects of sheet piles installed with the "silent" piler.

Before completing her PhD, Francesca joined Mott MacDonald (Cambridge) in March 2015, since then she has been working on a number of projects in Cambridge and outside Cambridge for the design of retaining wall, pile capacity, settlement calculation and various other geotechnical related problems.

She has also given some consultancy advice on the possible use of the "silent" piler for flood protection schemes in Boston and Shoreham.
