Abstract
The method involves supplying a dry binder through a sink pipe (11) sunk into the ground. The sink pipe has a cylindrical cladding pipe (12), an inner pipe (13) and a flap (17) at its lower end. The sink pipe is driven vertically into the ground to a predetermined depth, with the flap closed. The inside of the cladding pipe is supplied with dry binder, and at the same time air is drawn from the lower end of the pipe up through the inner pipe. After the cladding pipe has been filled to a partial height with dry binder, the sink pipe is drawn from the ground with the flap open, while further binder is supplied, so that a column of dry binder is left in the ground. An Independent claim is included for a device for implementing the method.
