Description

Technical Field

[0001] The utility model relates to the technical field of drilling, in particular to large-scale drilling equipment used for road and bridge construction. Background Art

[0002] Roads and bridges are generally composed of several parts, such as roadbed, pavement, bridges, tunnel projects and traffic engineering facilities. The roadbed is a linear structure built with soil or stone. Bridges generally refer to structures built on rivers, lakes and seas to enable vehicles and pedestrians to pass smoothly. The pavement is a layered structure paved in layers on the highway roadbed with various road construction materials or mixtures for vehicles to travel. In actual use, it is inconvenient for workers to operate the drilling equipment, which affects the efficiency of road and bridge construction. In addition, the drilling equipment is easily vibrated during the drilling process, resulting in the displacement of the drilling position. Therefore, we propose a large-scale drilling equipment for road and bridge construction. Utility Model Content
