DEVICE AND METHOD FOR FORMING MOLE DRAIN AND WATER PASSING GROOVE FORMATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a device and a method for forming a mole drain capable of efficiently and uniformly performing the throwing-in and charging of a filter material into a mole drain simultaneously with the formation of the mole drain. SOLUTION: This device comprises a blade 21 rotatably fitted to a work machine allowed to run, a bullet 22 fitted to the rotating end part of the blade, a filter material hopper 23 arranged continuously with the advancing direction rear side of the blade, a filter material supply port 24 opening to the lower rear side of the filter material hopper, and a drive means (cylinder) rotating the blade to both waiting positions where the bullet is positioned on the ground on a work machine side and on the ground on an anti-work machine side relative to the working positions in the state of the bullet inserted into the ground. The filter material thrown into the filter material hopper is supplied from the filter material supply port into the mole drain excavated by the blade and the bullet while the blade in a state that the bullet is inserted in the ground is advancing in a mole drain excavating direction.
