The construction of the temporary quay for the works of the Canal Seine-Nord Europe in Allaines, on the edge of the Canal du Nord, requires the installation of sheet piles in the ground to support the wharf, stabilize the ground and seal the walls of the channel. In June 2023, a preliminary phase of sheet piling tests took place. It made it possible to determine the work technique best suited to the characteristics of the terrain. Following this, construction work on this wharf will begin with the installation of the first sheet pile wall.
At the end of the trial phase in June, the driving technique by vibro-driving was chosen: it is the least noisy method for local residents.
In case of difficulty, the threshing (which generates more noise) can be used occasionally, as a last resort.
Le vibrating is used to drive sheet piles into the ground. It uses a specialized machine, the vibratory hammer, which transmits high-frequency vibrations to the sheet piles placed above the ground. These vibrations act on the soil to reduce its resistance, thus facilitating the passage of the sheet piles.
This method allows the sheet piles to be driven faster and with less effort compared to other techniques. It is often used in the construction of quays, retaining walls and structures.
Installation of the main sheet pile wall will take place from August 8 to 25, 2023, Monday to Friday (except Tuesday August 15), daytime from 7:30 a.m. to 19 p.m.
