Abstract (en)
[origin: EP1452645A1] A method for preparing underground slit walls has a slitting head (10) comprising a support frame (10) with one or two rotating cutting discs (12, 12') lowered into the ground by a telescopic support. The slitting head removes materials from under the head and the spoil is directed to the void above the head. At the same time a binding fluid is injected into the spoil via a duct (41) terminating at the slitting head. The slit is cut by repeated raising and lowering of the slitting head, which mixes the setting fluid with the spoil. The spoil and setting fluid set eventually to form the slit wall.
