In order to promote the supply and evacuation of materials from the Seine-Nord Europe Canal (CSNE) construction sites by river and thus limit truck traffic, the construction of the Canal relies on current navigable infrastructure; the lateral canal to the Oise and the canal du Nord. Thus, the Société du Canal Seine-Nord Europe is developing several quays dedicated to CSNE work on these canals, close to the construction sites.
In the south of the route, the first two docks located at Ribécourt-Dreslincourt and Pimprez were carried out in 2021-2022. Positioned on the Oise lateral canal which will be widened and deepened to become the CSNE, they are already used as part of the works (and reserved exclusively for this use for the moment).
The Pimprez quay, for example, made it possible to evacuate wood from deforestation carried out to free up the CSNE rights-of-way and is also used as part of the construction of the RD 40 bis bridge. The Ribécourt-Dreslincourt quay, in addition to its proximity to the construction site, is also close to a railway line which is the subject of connection work in conjunction with SNCF Réseau to enable multimodal logistics.
In Noyonnais, two other quays will be built in Noyon and Catigny and an existing quay in Pont l'Évêque will be redeveloped.
Sheet piles, steel profiles approximately 12 meters long, are driven into the ground by vibrations (vibrodriving) and sometimes, depending on the nature of the ground, using a pneumatic hammer (sliding mass on a mast). They make it possible to form a curtain which contributes to the sealing of the Canal.
A counter-curtain, made up of smaller steel profiles 4 to 5 meters long, is made a few meters from the sheet pile curtain depending on the size of the quay.
The area between the sheet piles (main curtain) and the counter curtain is leveled to install tie rods (metal bars) in the ground to ensure the junction between the steel profiles and thus stabilize the whole
The materials between the canal and the new quay are excavated then ddifferent equipment is installed on the platform like:
* The techniques used to create transshipment docks vary depending on soil characteristics. The stages explained above correspond to the construction stages of the Pimprez and Ribécourt-Dreslincourt quays. The construction of the Noyon work platform will not include stages 2 and 3 (installation of the counter-curtain and tie rods) because the good characteristics of the ground do not require the installation of these reinforcements.
