Apparatus and method for multiple spindle kneading for improving ground
Patent
·
OSTI ID:6861834
A number of agitation spindles are disposed, and an agitation vane is attached to the lower portion of each agitation spindle. A mixing and kneading zone for mixing and kneading soft soil with a hardener is formed so that the hardener is supplied near these agitation vanes. The agitation spindles are supported by reinforcing members and connecting members to construct a multiple spindle-kneading apparatus for improving ground. In one embodiment, blade-like excavating cutters are mounted on the agitation spindles. In another embodiment, hollow agitation spindles are used and the hollow portions are used as hardener passages. In still another embodiment, a tube for injecting the hardener into the mixing and kneading zone is disposed so that it can be moved up and down. A method for hardening soft ground in which the hardener feed position can be changed is provided. (11 claims)
