Claims (1)
における中心軸を有しないスクリューコンベアによる排
土装置において、この排土スクリュー１２の外側縁に土
砂の圧密、止水用の中心に向う土砂の掻寄せ羽根１８を
設けると共に内側縁には中心の空洞を通じての土砂流出
防止羽根１９を設けた土圧式シールド工法における土砂
の流出防止、止水羽根を備えたスクリュ一式排土装置。In an earth removal device using a screw conveyor that does not have a central axis in a shield excavation device for excavating water-retaining sand and gravel layers containing boulders, large-diameter gravel, etc., there is a center on the outer edge of this earth removal screw 12 for compaction of earth and sand and for water stopping. This screw set earth removal device is equipped with a water stop blade and a blade 18 for raking earth and sand, and a blade 19 on the inner edge to prevent earth and sand from flowing out through a central cavity in the earth pressure shield construction method.
