Description

Side digging device of rotary drilling rig Technical Field The utility model relates to the technical field of rotary drilling rig equipment, in particular to a side drilling device of a rotary drilling rig. Background Pile forming modes in modern pile foundation engineering are mainly divided into precast piles and cast-in-place piles. And (5) driving the prefabricated foundation pile into the soil by using equipment to obtain the prefabricated pile. The pile forming operation of the precast pile is difficult, the construction efficiency is low, the ecological environment around the construction site and the life of residents can be greatly influenced, and the precast pile is rarely applied to the construction site at present. The cast-in-place pile is formed by casting piles in pile holes after hole forming operation. The pile-forming size of the cast-in-place pile is more free than that of the precast pile, the single pile after pile-forming pouring can support larger load, the pile-forming process difficulty is low, and the construction efficiency is high. Because of the advantages, the cast-in-place pile is currently the mainstream pile forming technology in modern pile foundation engineering, and has wide application in high-rise buildings, bridge construction and other engineering. The widespread use of cast-in-place piles in geotechnical operations has also greatly prompted the development of piling machinery, with rotary drilling rigs as one of the most advanced piling machinery currently available. The rotary drilling rig is mainly used for vertical drilling operation, and drives the drill bit to rotationally cut rock and soil through the drill rod, so that drilling slag is brought out of a hole to finish hole forming. However, in actual engineering, for example, when an urban subway tunnel is constructed, lateral excavation needs to be performed when an existing structure is drilled nearby, an underground pipeline is avoided in bridge pile foundation construction, or under special scenes that a building foundation is reinforced and needs to be laterally perforated in a limited space, the conventional rotary drilling rig is difficult to meet construction requirements due to lack of lateral excavation function.
