Problems solved by technology

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 th...

Embodiment 1

[0035] see figure 1 , the present invention provides a multi-functional drilling coring machine drill device, which includes a drill bit, a level adjustment mechanism 1, a soil core suction mechanism 2 and a scale measurement mechanism 3, the top wall of the drill bit is provided with a level adjustment mechanism 1, the drill bit A soil core suction mechanism 2 is arranged inside, and the soil core suction mechanism 2 includes a T-shaped operating rod and a suction cup 21 arranged at its lower end. Out of the through groove, and fixed on the side wall of the drill bit by a locking mechanism, the side wall of the drill bit is also provided with a scale metering mechanism 3.

[0036] When the above-mentioned drill bit device is in use, firstly, the drilling operation is completed to obtain the concrete soil core separated from the road surface; secondly, by controlling the T-shaped operating rod to slide downward along the vertical groove on the side wall of the drill bit, the s...

Embodiment 2

[0045] The present invention provides a kind of construction method utilizing the drill bit device of multifunctional drilling coring machine, and this method comprises the following steps:

[0046] S1. Move the T-shaped operating lever up to the highest point, and then lock and fix it;

[0047] S2, use the level adjustment mechanism 1 to adjust the drill bit device to vertical;

[0048] S3, carry out the drilling operation, when the drilling depth reaches the specified scale of the scale metering mechanism 3, stop drilling;

[0049] S4, cancel the fixation of the soil core suction mechanism 2, and move down the T-shaped operating rod until the suction cup 21 sucks the soil core;

[0050] S5. Move up the T-shaped operating rod, drive the soil core to move up to the highest point, and lock and fix the T-shaped operating rod;

[0051] S6, lift up the drill bit device, and take out the soil core and the drill bit device together.

[0052] Preferably, in step S1, before lifting...

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...
