Shaft excavating device

Abstract

Abstract PURPOSE:To improve workability by sequentrally setting at least a front wheel liftable in relation to a truck and further directly connecting a casing tube press-fit swivel mechanism to the truck while forming the truck in a wheel- running type. CONSTITUTION:After a truck 1 is stabilized by an outrigger 1a after running the truck 1 to a predetermined position, a band 8 is set in an excavation position while mounting a reaction force weight 11 onto a base 7 integrally formed with the truck 1. Next a casing tube T is fitted inside the band 8 and clamped by a clamp cylinder 8a. Then the tube T is press-inserted into the ground by a giving a reciprocating turn motion to the tube T by a lift cylinder 10.
