Drill bit device of multifunctional core drilling machine and construction method

Abstract

The invention provides a drill bit device of a multifunctional core drilling machine and a construction method. The drill bit device of the multifunctional core drilling machine comprises a drill bit, a level adjusting mechanism, a soil core suction mechanism and a scale metering mechanism; the level adjusting mechanism is arranged on the top wall of the drill bit; the soil core suction mechanism is arranged in the drill bit and comprises a T-shaped operating rod and a suction cup arranged at the lower end of the T-shaped operating rod; symmetrical vertical through grooves are formed in the side wall of the drill bit; two ends of a cross beam of the T-shaped operating rod penetrate out of the through grooves and are fixed on the side wall of the drill bit through locking mechanisms; and the scale metering mechanism is arranged on the side wall of the drill bit. The drill bit device integrates the functions of drilling and coring, levelness monitoring and drilling depth measurement, can achieve one-time operation of drilling and coring, is simple in structure and convenient to operate, brings convenience to constructors to control the drilling depth and perpendicularity, and ensures construction precision.

Description

technical field [0001] The invention belongs to the technical field of road engineering construction, and in particular relates to a drill bit device of a multifunctional drilling and coring machine, and also relates to a construction method for drilling and coring construction using the device. Background technique [0002] In the construction of municipal construction, when it is necessary to carry out quality inspection or road reconstruction on the road surface, it will involve the construction operations of drilling and coring the concrete pavement. However, traditional drilling machines can only complete the drilling operation generally, and the concrete soil core after drilling will still remain in the drilled hole, and subsequent coring operations need to be combined with other mechanical equipment to remove the concrete soil core. Such a construction method not only has cumbersome steps, prolongs the construction time, but also increases the difficulty of road const...

However, traditional drilling machines can generally only complete the drilling operation, and the concrete soil core after drilling will still remain in the drilled hole, and subsequent coring operations need to be combined with other mechanical equipment to remove the concrete soil core

Such a construction method not only has cumbersome steps, prolongs the construction time, but also increases the difficulty of road construction operations.

[0003] In addition, this existing drilling equipment also has the following two deficiencies: on the one hand, the depth of the hole cannot be known in real time during the drilling process, and the depth of the hole can only be judged by the experience of the construction personnel, which is difficult to ensure reliable construction accuracy; on the other hand, during the drilling process, the drill bit of the drilling rig is prone to deviation under vibration, which cannot ensure the verticality of the drilling hole, and when the deviation is serious, the drill bit will be stuck, which will affect the smooth progress of the construction work
