Abstract (en)
[origin: EP3037586A1] The process allows soils (20) and/or building structures (22) to be consolidated and consists of: producing in the soil (20), by means of drilling, at least one hole using a drill rod (10) with a drill bit (18) of single use type, the drill rod (10) comprising several hollow drill bars (12) arranged consecutively and connected to one another by means of coaxial sleeves (14), at least one of the sleeves (14) being provided with at least one lateral through opening (16) that places the inside of the sleeve (14) in communication with the outside, this opening (16) being closed by a check valve adapted to open when the pressure inside the sleeve (14) exceeds a predetermined value; leaving the drill rod (10) in the hole bored in the soil, so as to act as reinforcement; injecting into the drill rod (10), through the outer end thereof, at a pressure that causes opening of the check valves provided in the holes (16) of the sleeves (14), an expanding substance adapted to consolidate the surrounding soil and to constrain thereto the drill rod (10) acting as reinforcement. The device comprises the above drill rod.
