PROBLEM TO BE SOLVED: To provide an excavation and ground leveling/faring bucket superior in construction quality, by preventing deformation of a ground leveling/fairing bottom plate in ground leveling/fairing work, with a simple structure. SOLUTION: An excavation tooth member 18 is detachably installed in a plurality of adapters 17 fixed at a predetermined interval along a front end plate 12 of a bucket bottom plate 11. The adapters 17 are composed of an upper part 17a abutting on an upper surface 12a of the front end plate 12 and a front part 17b abutting on a front face 12b of the front end plate 12 and having on the front face a projection part 19 for detachably externally installing the tooth member 18. The front part 17b is not projected downward from both under surfaces of the bucket bottom plate 11 and the front end plate 12, and a ground leveling/faring bottom plate 21 is installed on both under surfaces of the bucket bottom plate 11 and the front end plate 12 without forming clearance.
