<P>PROBLEM TO BE SOLVED: To provide a device for discharging excavated soil with a bucket elevator capable of discharging excavated soil while progressively lowering a casing in accordance with a progress to deepen an excavation surface and the excavated soil generated when constructing a horizontal space after completion of a vertical shaft. <P>SOLUTION: An excavated soil discharging device comprises: a head casing arranged above the ground; a tail casing with a lower edge thereof positioned close to an excavation surface of a vertical shaft; a chain circulating between the head casing and the tail casing; and a plurality of buckets attached to the chain for transporting excavated soil, loaded into the bucket through a loading port at the tail casing, to the head casing for discharging the same. The present invention enables the excavated soil associated with the excavation of the vertical shaft to be discharged by the buckets while progressively lowering the tail casing in a manner to install and link a plurality of intermediary casings having the chain with buckets attached thereto, between the head casing and the tail casing as deepening of the excavated surface by excavating the vertical shaft progresses. <P>COPYRIGHT: (C)2012,JPO&INPIT |
