Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge construction equipment, in particular to a pavement cutting device for bridge roads. Background Art

[0002] Roads and bridges are composed of several major parts, including roadbed, pavement, bridges, tunnel projects and traffic engineering facilities. Roadbed engineering: The roadbed is a linear structure built with soil or stone. It bears its own rock and soil weight and the gravity of the pavement, as well as the traffic load transmitted by the pavement. It is an important part of the entire highway structure. The highway roadbed mainly includes several parts such as the roadbed body, side slopes, side ditches and other ancillary facilities; Pavement engineering: The pavement is a layered structure paved in layers on the highway roadbed with various road construction materials or mixtures for vehicles to travel. After the pavement construction is completed, due to the characteristics of thermal expansion and contraction of concrete, it is necessary to use a slitting device to cut the seams before the concrete is completely cooled to avoid cracking of the concrete after cooling. Therefore, using a slitting machine for slitting is an indispensable part of pavement construction, which directly affects the strength and life of the pavement.

[0003] A ground cutter is a tool for road maintenance and construction. Its main function is to cut seams on the road surface, with a depth of up to 100-200mm. The existing cutting device structure has a low degree of electrification. The road surface thickness varies, resulting in different cutting thicknesses. Existing equipment cannot adjust the cutting depth. At the same time, the construction process is dusty, affecting the health of the operator. To solve the above problems, we proposed a cutting device for municipal road and bridge construction. Utility Model Content
