摘要： PURPOSE:To efficiently execute extension work of rods, particularly the extension work in the construction of a corner part, in a multi spindle auger machine allowing the extension of rods to have a large excavation depth. CONSTITUTION:A rotating device 2 having the axial line of a leader 64 is the rotating center is mounted on the lower end non-rotating part 54a of the leader 54, and a lower arm 3 and an upper arm 4 are provided on the rotating device 2 and the rotating part 54b of the leader 54, respectively. A guide bracket 5 is supported by the upper and lower arms 3, 4, and a lower part bracing body 1 is installed to the guide bracket 5. The lower part bracing body 1 is movable following the rotation of the leader 54.

摘要： PURPOSE: To carry out construction work very economically by providing only a thin film-like cut-off wall to an aquifer part in a deep position, and constructing an earth retaining cut-off wall bearing stress and having cut-off function upward thereof. CONSTITUTION: A narrow plate-like gutter 3 is excavated from the ground to a water-unpermeable layer by means of an excavator. Then, the plate-like gutter 3 is filled with cut-off materials, and a plate-like cut-off wall 2 cutting off an aquifer is vertically constructed within distance from the water- unpermeable layer to the ground. Then, an upward part of the cut-off wall 2 is widely cut up to required depth from the ground by means of earth auger, etc., and it is stirred to form a stirring gutter 6. Before the cut-off materials are solidified, stress materials 7 and 7 such as H-shaped steel materials are erected in the stirring gutter 6, and with the solidification of the cut-off materials, an earth retaining cut-off wall 1 is formed monolithically therewith having a sufficient strength, and equipped with cut-off function.

摘要： PURPOSE:To permit the removal work of anchor steel materials without limitation to grounds to be applied by a method in which when a contractile material is positioned on a grouting material and anchor steel materials are removed out, an expandible material is expanded in the grouting material to deform the contractile material by the expanding force of the expandible material. CONSTITUTION:An anchor steel material 1 of bundled contractile materials 3 and an injection tube 2 are inserted into an anchor pit 4, and a grouting material 6 is injected and hardened to fix the steel material 1 to the underground. When removing the steel material 1 from the underground, an expandible material is injected into the tube 2 exposed to underground and expanded, whereupon many cracks develop in the grouting material 6 adhered to the steel material 1 from the tube 2 in the fixed portion A toward the material 3 to accelerate crushing. The grouting material adhered to the steel material can thus be effectively crushed within necessarily minimized ranges.
