RECTANGULAR EARTH RETAINING SOIL WALL CONSTRUCTION METHOD AND RECTANGULAR EARTH RETAINING SOIL WALL EXCAVATOR

摘要

PROBLEM TO BE SOLVED: To construct a rectangular earth retaining soil wall easily by digging the ground by a rectangular earth retaining soil column row wall excavator on which a vibration plate is attached, scraping out earth which is not digged out by the vibration plate, and pouring stabilizer and solidifying it. ;SOLUTION: A vibration plate 8 which forms a vertical plate and vibrates in the vertical direction is provided at an intermediate position between two adjacent digging bits in plan at a position just close to a shaft interval hold member when viewed in the direction of elevation and a stirring blade. A material of the vibration plate 8 is steel, and it is made of steel in the groove shape having a flange 8a on both sides. It has a tapered shape when viewed in the direction of side and is arranged in parallel with both outside positions of a stirring digging shaft 1 at the same interval as diameter of tip circle of the digging bit and the stirring blade. While the ground is digged down to required depth by the digging stirring shaft 1, a part which is not digged is scraped out by the vibration plate 8, and stabilizer is poured into the soil, stirred, mixed, and solidified. Consequently, it is possible to construct a rectangular earth retaining soil wall easily irrespective of type of ground and constitution of ground layer.;COPYRIGHT: (C)1997,JPO
