Support for an Elevator Shaft in Carrefour de Touques, France

Techno Metal Post adapts to all your projects!

During the night of May 17, 2022, a Techno Metal Post team arrived at Carrefour de Touques for a unique job. The project needed to be carried out after work hours as not to disturb the regular business flow. The installation of helical piles was needed to support a storeroom elevator shaft.

Ground conditions were poor, with a survey indicating the start of dense soil at 16m (52 feet). The first challenge was positioning the installation machine in its work area: access was narrow and low pipes obstructed installing 2 out of the 10 piles required. At 9pm, after finding the right working position (and without risking store wall damage) the helical pile installation began. The required bearing capacity is reached with the first pile at a depth of 22m (72 feet).  A shipment of pile extensions was quickly obtained, given that 18m (59 feet) had originally been planned. The alternating process of screwing and welding continued throughout the night.

By 8:10 the next morning, all the piles were installed, set at the required height, and head plates welded. A team of two professionals, which included a welder, successfully installed 10 helical piles measuring between 18 to 24 meters (59-78 feet) in length. The satisfied customer was surprised by the efficient overnight installation, consisting of just over 200 meters (656 feet) of piles!

Under the direction of Sylvain Jirot, a unique challenge of meeting deadlines kept arising. All the dealership's teams were busy, which affected the project's original deadlines. Two of the network's installers (Reginald Nardeau of Techno Pieux Picardie Ouest and Pierre de Franssu of Techno Pieux Martinique) were available to come and carry out the project, ensuring it was completed on time.
