Abstract
This utility model relates to a kind of new drill structure, it includes drill bit and guide cylinder, guide cylinder is cylindrical structural, cross is set in guide cylinder, drill bit is arranged on cross, drill bit is positioned at inside guide cylinder, and the spacing bottom drill bit and between guide cylinder bottom surface is 3 8cm, is equipped with carbide button bottom described cross, drill bit and guide cylinder.This utility model is by using above-mentioned technology; guide cylinder is set outside conventional bit; under the guide effect of guide cylinder; make bit bore accurate; will not offset; improve construction quality; it is equipped with carbide button bottom cross, drill bit and guide cylinder; improve its efficiency of construction, and drill bit is positioned at inside guide cylinder by this utility model, and the spacing bottom drill bit and between guide cylinder bottom surface is 3 8cm; while boring; mud from drill bit out, protects guide cylinder immediately, when preventing boring on guide cylinder carbide button is overheated and excessive wear.
Description
Technical field
This utility model belongs to construction technical field of tools, is specifically related to a kind of new drill structure for drilling concrete priming concrete pile hole.
Background technology
At present, it is that more than 12m basic uses what campshed added water-stop curtain to go along with sb. to guard him mode in the excavation of foundation pit degree of depth, go along with sb. to guard him campshed and all use interval construction, clear distance between stake and stake is typically at 20-30cm, the 3rd filling concrete stake holes is made a call to such as first filling concrete stake holes again after accomplishing fluently, then making a call to second filling concrete stake holes, therefore need to ensure that each hole site accurately and does not offsets when punching, pile hole construction the most below cannot be carried out.And tradition puncher uses the construction of domestic slewing drilling machine, due to this equipment own characteristic, normal conventional drill bit is used to be difficult to control very well in construction perpendicularity, if occurring in Shi Gong that perpendicularity deviation is bigger, so will affect the construction of follow-up stake, cause construction speed impacted, reduce efficiency of construction.
Utility model content
For the above-mentioned problems in the prior art, the purpose of this utility model is to provide a kind of new drill structure for drilling concrete priming concrete pile hole.
Described a kind of new drill structure, it is characterised in that including that drill bit and guide cylinder, described guide cylinder are cylindrical structural, arrange cross in guide cylinder, drill bit is arranged on cross, is equipped with carbide button bottom described cross, drill bit and guide cylinder.
Described a kind of new drill structure, it is characterised in that drill bit is positioned at inside guide cylinder, and the spacing bottom drill bit and between guide cylinder bottom surface is 3-8cm.
Described a kind of new drill structure, it is characterised in that drill bit is corner cone structure, carbide button is arranged on four ribs of corner cone.
Described a kind of new drill structure, it is characterised in that guide cylinder height is 50-60cm.
Above-mentioned a kind of new drill structure, including drill bit and guide cylinder, described guide cylinder is cylindrical structural, cross is set in guide cylinder, drill bit is arranged on cross, drill bit is positioned at inside guide cylinder, and the spacing bottom drill bit and between guide cylinder bottom surface is 3-8cm, is equipped with carbide button bottom described cross, drill bit and guide cylinder.This utility model is by using above-mentioned technology, guide cylinder is set outside conventional bit, under the guide effect of guide cylinder, make bit bore accurate, will not offset, improve construction quality and construction perpendicularity, cross, it is equipped with carbide button bottom drill bit and guide cylinder, improve its efficiency of construction, and drill bit is positioned at inside guide cylinder by this utility model, and the spacing bottom drill bit and between guide cylinder bottom surface is 3-8cm, while boring, mud is from drill bit out, immediately guide cylinder is protected, carbide button on guide cylinder and guide cylinder is overheated and excessive wear when preventing boring.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
In figure: 1-cross, 2-guide cylinder, 3-drill bit, 4-carbide button.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model will be further described, but protection domain of the present utility model is not limited to that:
As shown in the figure, a kind of new drill structure of the present utility model, including drill bit 3 and guide cylinder 2, described guide cylinder 2 is cylindrical structural, and it is highly typically set to 50-60cm, arranges cross 1 in guide cylinder 2, drill bit 3 is arranged on cross 1, being equipped with carbide button 4 bottom described cross 1, drill bit 3 and guide cylinder 2, and drill bit 3 is corner cone structure, carbide button 4 is arranged on four ribs of corner cone.
As shown in the figure, it is internal that drill bit 3 is arranged on guide cylinder 2 by this utility model, and the spacing bottom drill bit 3 and between guide cylinder 2 bottom surface is 3-8cm, during boring, first worked by the carbide button 4 of guide cylinder 2, make guide cylinder 2 connect to move down, ensure that the perpendicularity of boring, simultaneously, drill bit 3 work is holed, this utility model will be set to 3-8cm bottom distance guide cylinder 2 bottom drill bit 3 simultaneously, make guiding more accurate, and while boring, immediately lower the temperature to bottom guide cylinder 2 from drill bit 3 water out, prevent carbide button 4 from damaging, while improving efficiency of construction, extend the service life of guide cylinder 2.
