SEDIMENT REMOVAL BUCKET AND SEDIMENT REMOVAL METHOD
PROBLEM TO BE SOLVED: To provide a sediment removal bucket and a sediment removal method which enable excavated sediment inside a vertical shaft to be discharged with improved reliability.SOLUTION: A sediment removal bucket comprises: a container body which has a cylindrical trunk section, a bottom section at a lower end of the trunk section and an upper opening; and a tubular air distribution section which is arranged inside the trunk section with a lower edge thereof connected to the bottom section. The bottom section has: an inner side surface which constitutes a portion of an inner peripheral surface of the container body with the lower edge of the air distribution section connected thereto; an outer side surface opposite to the inner side surface; a claw which is downwardly extended from the outer side surface to scoop up residue; and an air outlet which is arranged at a position on the outer side surface corresponding to the lower edge of the air distribution section and communicated with the air distribution section.SELECTED DRAWING: Figure 12
【課題】掘削した縦穴内の土砂を、より確実に排出可能な土砂除去バケット、及び土砂の除去方法を提供することを目的としている。【解決手段】筒状の胴部と胴部の下端部に設けられた底部とを含み、上部が開放されている容器本体と、胴部の内側に配置され、下端が底部に接続された管状の空気流通部とを備え、底部は、容器本体の内周面の一部を構成し、空気流通部の下端が接続された内側面と、内側面の反対側に形成された外側面と、外側面から下側に突出して形成され、残留物を掻き上げる爪と、外側面のうち空気流通部の下端に対応する位置に形成され、空気流通部に連通する空気流出口とを含むものである。【選択図】図１２
