Auger combined use pressing in construction method and auger device and lagging

摘要

PROBLEM TO BE SOLVED: To provide an auger use press-in construction method using an auger, an auger device thereof, and a sheet pile thereof capable of improving precision and work efficiency of pressing-in and enabling auger use pressing-in in a narrow place without necessitating high crane lift.;SOLUTION: This auger use pressing-in construction method is composed of processes that an auger casing 3 is arranged along a web 2 of the sheet pile 1 to be pressed in and the sheet pile is pressed in by a pressing-in machine while excavating the ground by a rotary auger in the auger casing 3. When the sheet pile 1 is pressed in, fitting and fixing mechanisms 6, 7 which guide the sheet pile 1 received along the auger casing 3 so as to pull it close to the auger casing 3 and fix the sheet pile 1 at a predetermined position of an outer peripheral face of the auger casing 3 so that it adheres closely on the predetermined position thereof are provided between an outer peripheral part of the auger casing 3 and the sheet pile 1, and the sheet pile 1 and the auger casing 3 adhere closely and are fixed by the fitting and fixing mechanisms 6, 7 to press in the sheet pile 1 by the pressing-in machine.;COPYRIGHT: (C)2001,JPO
