PROBLEM TO BE SOLVED: To provide a shaft excavation and soil-gathering method with which soil-gathering work can be performed safely and speedily by a simple method.SOLUTION: According to a construction method for safely and speedily performing soil-gathering work, a plurality of rails 4 are successively laid and fixed vertically downward to a liner plate 2 in a shaft 1 by a horizontal mounting plate 5 in accordance with excavation depth of the shaft 1. A soil-gathering bucket 6 is provided which may be lifted up and lowered along the rails 4. Regarding excavated soil which is generated in the process of excavation, the soil-gathering bucket 6 is driven to be lifted up and lowered by a wire rope 8 along the rails 4 laid successively, such that excavated soil is lifted up to the ground G and discharged outside of the shaft 1. Thus, the soil-gathering bucket 6 is lifted up and lowered along the rails 4 laid within the shaft in accordance with the excavation depth, such that soil-gathering work is performed safely and speedily. |
