Abstract

PURPOSE:To treat the shallow layer of a soft soil layer by hardening treatment in which a girder projecting from the side end of a feeding base to the outside is provided, and by a stirrer moving on the girder, hardening treatment is applied to the untreated zone adjacent to the forward hardening treatment zone. CONSTITUTION:While operating a stirring means 12, a truck 8 is moved from arrow (b) toward arrow (a) on a girder 7 to form a hardening treatment zone Q. A feeding base 4 is moved in the direction of arrow (c) and its operation is repeated until a forward hardening treatment zone 1A is adjoined, where a backward hardening treatment zone 1A' is formed in an untreated zone 6 in such a way that part of the zone is plied. The operation is continued until the backward hardening treatment zone 1A' comes to meet with the forward hardening treatment zone 1B. Afterward, the running direction of the feeding base 4 is turned toward the direction of arrow (d) by a rotation base 21A and by the same operation, a backward hardening treatment zone 1B' is formed in the untreated zone 6. The operations are repeated while turning the rotation bases 21B and 21C.
