EARTH REMOVAL TOOL, EARTH REMOVAL DEVICE, AND EARTH REMOVAL METHOD
To solve the problem of drawing in earth and sand outside a reinforcement steel plate and to provide an earth removal tool of an earth removal device, an earth removal device, and an earth removal method having good workability in final stage earth removal work and being able to cleanly remove earth and sand at corners and at the bottom of the reinforcement steel plate.SOLUTION: An earth removal tool of an earth removal device for removing earth and sand from a gap between a reinforcement steel plate and an existing columnar structure when press-fitting the reinforcement steel plate around the existing structure has a cylindrical earth removal tool body with upper and lower ends opened, and an injection port for injecting compressed gas formed in a side plate of the earth removal tool body. A suction cutout for sucking in earth and sand is formed in the vertical direction on the front plate on the side of the existing structure of the earth removal tool body. On the opposite side back plate, no cutout is formed as the lower end is linearly lowered from the upper end of the suction cutout.SELECTED DRAWING: Figure 2
【課題】補強鋼板外部の土砂を引き込んでしまうという問題を解消して、最終段階の排土作業の作業性が良好で、隅角部や補強鋼板最下部の土砂もきれいに排土することができる排土装置の排土治具、排土装置、及び排土方法を提供する。【解決手段】柱状の既設構造物の周りに補強鋼板を圧入する際に、この補強鋼板と既設構造物の隙間の土砂を排土する排土装置の排土治具において、上下端が開放された筒状の排土治具本体を具備し、この排土治具本体の側面板に、圧縮気体を注入する注入口を形成するとともに、前記排土治具本体の既設構造物側となる正面板に、上下方向に土砂吸引用の吸引欠込みを形成し、反対側となる背面板に、下端が前記吸引欠込みの上端より下方へ下がった直線状として欠込みを形成しない。【選択図】図２
