Document Type and Number:
Japanese Patent JPH08296223
Kind Code:
A
Abstract:

PURPOSE: To eliminate a form so as to improve the working efficiency by fitting an excavating unit, which is provided with an agitating vane and a cement milk supplying pipe or the like, to a working machinery such as a power shovel, and building an underground retaining wall of the excavated sediment.

CONSTITUTION: A unit 19, which is provided with a trench excavating device 51 and a retaining wall building device 53, is fitted to an arm of a working machine freely to be disconnected, and the working machine is moved back in the arrow direction, and a trench for retaining wall at the predetermined width and the predetermined depth is excavated. A part of the excavated sediment is mixed with the cement milk, which is supplied from a milk supplying pipe 65, by an agitating vane 73 and projections 75, and filled inside of the excavated trench, and solidified so as to form a retaining wall. In this case, a core material 76 made of reinforcement and wire net is arranged at need. The retaining wall is built at the same time with the excavation of the trench without providing a form. The work can be thereby simplified, and the construction period can be shortened.
