摘要： PROBLEM TO BE SOLVED: To provide a vertical shaft excavation device capable of efficiently carrying out vertical shaft excavation work while lessening man-power work by promoting mechanization even under such a difficult condition that large-sized heavy equipment can not be carried in or used.
SOLUTION: The vertical shaft excavation device includes a supporting basic stand 5 directly or indirectly receiving supporting reaction force from the interior wall surface 3 of a vertical shaft 1, a center post 9 extended along the center of the vertical shaft 1, capable of making relative movement downward to the supporting basic stand 5 and being turned with the center line as the center, and, forming an excavated earth and sand taking opening 7 in the lower side section, a helical drum excavator 13 extended from the lower side section of the center post 9 in the horizontal direction, excavating the bottom ground 11 of the vertical shaft 1 while turning it combining with the center post 9 and, at the same time, conveying the excavated earth and sand to the inside of the center post 9 through the opening 7 and a bucket conveyor 15 provided to the inside of the center post 9, traveling in an endless state along the extended direction, excavating the central part of the bottom ground 11 of the vertical shaft from an opening 9A formed in the lower end of the center post 9 in advance and, at the same time, conveying the excavated earth and sand and the excavated earth and sand conveyed to the insid of the center post 9 through the opening 7 from the excavator 13.
