The invention belongs to the technical field of municipal construction and particularly relates to a dust-proof and noise-reduction cutting device based on municipal construction. Aiming at the problem that a cutting device for municipal construction generates a large amount of flying dust which is adverse to body health, the following schemes are proposed currently, specifically, the dust-proof and noise-reduction cutting device comprises a base; supporting rods are mounted to the two sides of the two ends of the outer wall of the bottom of the base through bolts correspondingly, and moving wheels are mounted on the outer walls of the bottoms of the supporting rods through bolts; vertically-arranged hydraulic rods are mounted at the four corners of the outer wall of the bottom of the basethrough bolts correspondingly, and anti-skidding blocks are mounted on the outer walls of the bottoms of the hydraulic rods through bolts; and a working box is mounted in the middle of the outer wallof the top of the base through bolts. According to the dust-proof and noise-reduction cutting device, the cutting process of a cutting blade is executed in the working box, chippings and flying dustwhich are generated in the cutting process are prevented from diffusing into air, and thus body health of a worker is benefited; and meanwhile the chippings and the dust are sucked into a duct collecting box through a dust suction pipe and a dust suction motor, and thus clearing is easy and convenient.
