Zusammenfassung:	PROBLEM TO BE SOLVED: To accurately correct unevenness of a wall surface 2 and the like on the upper stream side of a body 1 of dam with high efficiency.SOLUTION: Guide rails 11 and 12 are installed in a vertical direction along a wall surface 2. An excavator 20 is hung by a crane 30, and lifted/lowered along the guide rails 11 and 12. The excavator 20 comprises a part (endless roller 25) abutting on the guide rails 11 and 12, and an excavation part (twin header 26) for excavating the wall surface 2. Additionally, a reaction reception mechanism (wire 32) for receiving reaction from the wall surface 2, for example, by supporting the excavator 20 from its rear side is provided.SELECTED DRAWING: Figure 1 【課題】ダム堤体１の上流側の壁面２などの不陸整正を高効率にかつ精度良く実施する。【解決手段】壁面２に沿って上下方向にガイドレール１１、１２を設置する。クレーン３０により掘削機２０を吊り下げ、ガイドレール１１、１２に沿って昇降させる。掘削機２０は、ガイドレール１１、１２への当接部（エンドレスころ２５）、及び、壁面２を掘削する掘削部（ツインヘッダ２６）を備える。また、掘削機２０をその背面側から支持するなどして、壁面２からの反力を受ける反力受け機構（ワイヤ３２）が設けられる。【選択図】図１
