A method for gradually introducing thin-walled pipes into the ground includes inserting a pipe clamp, which has been arranged horizontally on a mast, into a horizontal pipe, bracing the pipe clamp (pipe gripping jaw) with the rear part of the pipe, moving the pipe clamp back with the pipe braced thereon, erecting the mast, with the tools, the pipe clamp and the pipe, into a vertical position, introducing the pipe to the desired depth with the tools, unclamping the pipe clamp and pulling it out of the pipe, and repositioning the mast back into a horizontal position. A device has a carrier unit, a mast, which can be pivoted between vertical and horizontal, tools with a pipe clamp, arranged on the mast, and a magazine a pipe arranged substantially horizontally. The pipe clamp is inserted into the pipe coaxially in relation to the pipe and substantially horizontally.
