摘要：
PROBLEM TO BE SOLVED: To provide an underground excavator capable of surely excavating a verge of each wall of an underground structure such as a caisson or the like and the lower part of an edge to prevent the ground subsidence around the underground structure.
SOLUTION: In the underground excavator 11 excavating a bedrock in the water of the inside of the caisson 1 when the caisson 1 is constructed, it includes a water jet propulsion device 14 driving an excavator body 12 in the optional direction, a vacuum absorption system 16 adhering to the wall surface of the caisson 1 and a bucket type excavator 17 excavating the bedrock G around the lower part of the wall surface.
