摘要

PROBLEM TO BE SOLVED: To excavate earth and sand while freely reciprocating when the equipment moves laterally. SOLUTION: Earth and sand excavating suction equipment 1 is provided with an excavating nozzle 22 for spraying compressed air to the ground face 2 to excavate in a suction cylinder 21 formed in a cylindrical shape substantially vertically installed on the ground face 2 to be excavated. The earth and sand of the ground face 2 is broken by the compressed air blown out from the excavating nozzle 22. The earth and sand is sucked together with the compressed air from the lower end of the suction cylinder 21. This earth and sand excavating suction equipment 1 is provided with a brush member 31 covering between the suction cylinder 21 and the ground face 2 at the lower end of the suction cylinder 21.
