Description


The winning aspect of this highly productive technology is the combined action of rotation and pressure with a special tool which can move and/or amass soil in the drilling stage. This is an ideal “clean” solution for contaminated areas (refineries, garbage dumps, de-commissioned industrial areas, etc.) and is perfect for projects in urban areas. The DISCREPILES technology ensures very little debris, the absence of vibration and impulsive force or impact, increases the load-bearing capacity of pilings due to the compactness of the soil in the surrounding area (limited to incoherent “compactable” soils). This method significantly reduces the over-consumption of concrete and eliminates any risk of over-augering.

Operating specifications
The operating method entails driving a hollow drill stem equipped with a special “tamper” which moves and/or amasses the soil as it advances. Once the projected depth has been reached, the drill stem is extracted and at the same time the pile is poured by pumping concrete through the same hollow drill stem. Where required, piles can be reinforced for their entire length with reinforcement cages inserted in the still wet concrete.

Technical data
Pile diameter: 300 to 600 mm; larger diameters up to 900 mm only in particularly favourable soil conditions.
Depth: 25 ÷ 30 meters depending on soil diameter and consistency.
