摘要： PROBLEM TO BE SOLVED: To enable continuous excavation by inserting an excavating work rod having a driving part into a hollow pile by pressing the hollow pile in the ground while rotating it leftward, and restraining revolution of a small gear by adjusting a rotating speed of a synchronous motor when the inside of the hollow pile is excavated by rotating the excavating work rod rightward. SOLUTION: After a hollow pile 6 is pressed by a necessary length in the ground, a screw auger 7 is inserted into the hollow pile 6, and a pile holding cylinder 8 is put on and fitted to an upper end part of the hollow pile 6, and a chuck piece 17 is press-fitted to an outer peripheral surface of the hollow pile 6. In this condition, the hollow pile 6 and a large gear 33 are respectively rotated in the anticlockwise direction, and the screw auger 7 is rotated by a motor of a driving part 13, and a small gear 38 is rotated by a synchronous motor 35, respectively in the clockwise direction. When there is a difference in peripheral velocity between the large gear 33 and the small gear 38, a speed of the synchronous motor 35 is changed, and revolution of the small gear 38 is restrained. Therefore, rotational reaction at inside excavating time of the screw auger 7 is received by the hollow pile 6, and the screw auger 7 can normally continue inner excavation.

摘要： PROBLEM TO BE SOLVED: To prevent a danger and the deterioration of work environment, and to miniaturize a base machine by a method wherein high-pressure water is injected from an excavation head, soil and sand are changed into excavated muddy water and lifted in a pit, soil and sand are separated and discharged and water is circulated and used. SOLUTION: An earth auger 2 is inserted into a pit 1, and an excavation bit 3 is installed to a head section and excavation is conducted. A guide post 11 is supported by a base machine 10, and the pit 1 is made perpendicular. High-pressure water is forwarded to the earth auger 2 by a high-pressure pump 20, and high-pressure water 22 is injected against a wall surface 23 in the ground from an excavation head through the inner tube of an earth auger shaft. Soil and sand on the wall surface 23 are excavated by infection, and slurry 24 is sucked by a slurry discharge pump 25. Slurry 24 is sent to a solid-liquid separator 30 through sections among the blades of the earth auger 2. Since mud is not discharged to the outside by separating slurry into water and removing earth 35 by the solid-liquid separator 30 and circulating and using a supernatant liquid 38, environment can be protected. The base machine 10 need not be scaled up.

摘要： PURPOSE:To correctly grasp the deflection of an excavating shaft by detecting the position and depth of the excavating shaft supported by a leader mast with sensors, calculating the displacement quantities of the tip of the excavating shaft based on the values, and displaying the results. CONSTITUTION:Displacement positions in the X-axis direction and Y-axis direction are detected by distance detecting sensors S1, S2, S1' S2'. provided on the bracing device 5 of the excavating shaft 3 such as a screw auger lifted or lowered along the guide rail 1a of a leader mast l. The rotation quantity (shift quantity of wire) of a winding winch 10 of a wire 9 suspending a driving device 2 is measured to detect the excavation depth of the excavating shaft 3. The deflection (inclination) of the excavating shaft 3 is calculated by an arithmetic device 7 based on the excavation depth detected value and the bracing position detected value from these two sensors and displayed on display sections 13, 14. Actions such as corrective excavations are taken in response to the results. Accurate detection can be made, and measuring instruments can be protected from vibrations and shocks.
