Description

Technical Field

[0001] The utility model relates to the technical field of pavement cutting, in particular to pavement cutting construction equipment. Background Art

[0002] Concrete pavement slitting refers to a construction method in which slits are cut on the concrete pavement to form gaps with a certain spacing to reduce the temperature stress of the pavement and control the cracking of the pavement. When building a concrete road, the cement hydration releases a lot of heat during the solidification and hardening process of the concrete, causing the concrete temperature to rise; most of the cement hydration reactions are completed and the concrete temperature begins to drop. During the cooling process, the concrete has already solidified and hardened. The shrinkage caused by the cooling will cause the concrete to crack, and the direction of the cracks is relatively random, which seriously affects the quality and service life of the pavement. Therefore, slitting should be performed after the concrete is laid.

[0003] As a prior art, a Chinese patent with a publication (announcement) number of CN214459469U discloses a pavement slitting device for road construction, including a main body support, a hydraulic rod, a diesel engine, a pulley mechanism, a rotating shaft, a second slitting wheel, a movable frame, a protective cover and a control rod, wherein a hydraulic rod is fixedly mounted on the side wall of the main body support, and rollers are movably mounted between the hydraulic rod and the bottom of the main body support, and a diesel engine is fixedly mounted on the upper surface of the main body support, one end of the pulley mechanism is fixedly mounted on the output shaft of the diesel engine, and the other end of the pulley mechanism is fixedly mounted on the rotating shaft, and the rotating shaft is movably mounted on a fixed plate.

Therefore, it is necessary to clean it in advance. If it is cleaned manually, there is a waste of manpower and material resources and the efficiency is low. In addition, the dust after the cutting is easy to adhere to clothing or float in the air, which has certain adverse effects on the body.

[0005] Therefore, a road surface cutting construction equipment is proposed. Utility Model Content
