[0002] Fine stone concrete is one of the common building materials in construction. Fine stone concrete needs to be poured during the construction of the foundation, walls, and floors of a building to ensure the structural strength and stability of the building. In order to further ensure the structural strength of the concrete building, the fine stone concrete needs to be roughened after it is poured and solidified. That is, grooves are chiseled out on the completed concrete structure surface to remove the floating slurry on the top, so that the construction surfaces of the two construction stages are more firmly bonded.

[0003] At present, the roughening of fine stone concrete floors usually uses chisels or pneumatic picks to roughen the smooth surface of the concrete. The roughening process is likely to cause fragments to fly, and long-term operation is likely to cause discomfort to the arms of construction workers. At the same time, a large amount of dust will be generated during the roughening process, and a large amount of dust will escape into the air, causing pollution to the environment and harming the health of construction workers.
