摘要

PURPOSE:To improve removal efficiency of a seashore withered surface of a base rock by providing the peripheries of water jetting nozzles with an annular nozzle for jetting air jets and rotating the above-mentioned nozzles. CONSTITUTION:A high-pressure water pump 15 and a compressor 16 are operated with a generator 17 and high-pressure water jets accompanying air jets are then jetted on a seashore withered base rock 19 to peel and remove the seashore withered surface. Plural nozzles for simultaneously jetting jet water and compressed air are provided through a double-pipe 2 and double swivel 3 on a cylindrical support, which is rotated with rotation of the swivel 3, etc.
