Abstract
The utility model discloses a filling pile aiguille which comprises a drill rod provided with a web plate and a retainer, wherein the top end of the drill rod is provided with a drill point, and the web plate is provided with an armpit pawl. The filling pile aiguille is characterized in that the lower end and side end of the web plate are both provided with an alloy head and the armpit pawl, and the retainer is fixedly connected with the drill rod through a rib plate and a diagonal rod; and the web plate is arranged below the retainer and an included angle between the web plate and the shaft line of the drill rod is 60 degrees, a positioning plate is arranged between the aiguille and the retainer, and the connecting position of the aiguille and the drill rod is provided with a stiffening plate. Compared with prior art, the filling pile aiguille provided by the utility model has the advantages that the drill point is stable, the vertical rigidity is large, the guide localization is good, the incision drilling of the aiguille is realized, the cutting and rabbling are better carried out on an earth mass, the construction speed is accelerated, and the construction cost is further lowered.
Description
Technical field
The utility model relates to building implements and technical field of tools, the castinplace pile drill bit that specifically a kind of cement stabilization earth-boring is used.
Background technology
Bored pile can be adjusted the long and stake footpath of stake flexibly because of being suitable for any stratum, and castinplace pile is the stake type of present main use.Along with the continuous expansion of bored pile range of application, the stratum of its application becomes increasingly complex, and the stratum that existing undisturbed soil has undisturbed soil to reinforce again generally adopts three-wing bit to hole when soft clay area is constructed.
Along with the high speed development of economic construction and urbanization, but in modern times in the city, often need transform the old building thing; And the Chang Youyong cement-soil was reinforced in the old building thing stratum, in new transformation process, needed add stake at the cement-soil stabilization zone, then was difficult to the stratum that circle abrasive drilling water inlet earth is reinforced during the three-wing bit of prior art; Speed of application is slow; Not only consume manpower and materials, also time-consuming costly, increased construction costs greatly.
The utility model content
The purpose of the utility model is a kind of castinplace pile drill bit that designs to the deficiency of prior art; Web that employing is obliquely installed and the spacing that strengthens web and apex point advance for cutting round abrasive drilling and creep into, and better the soil body are cut and stir; Accelerate speed of application, reduced construction costs.
The purpose of the utility model is achieved in that a kind of castinplace pile drill bit, comprises the drilling rod that is provided with web and guard ring, and the drilling rod top is provided with drill bit; Web is provided with the armpit pawl; Be characterized in that web is a right-angled trapezium, its base is provided with several alloy cutting heads, and hypotenuse is provided with several armpit pawls; Guard ring is fixedly connected with drilling rod with diagonal member by gusset, and several gussets are arranged on radially in the guard ring and weld with drilling rod and guard ring, and several diagonal members are arranged on top and the drilling rod and the guard ring welding of guard ring; Web is arranged on bottom and the drilling rod and the gusset welding of guard ring, and the last base of web and drill rod axis are 60 ° of angle welding, its right-angle side and gusset welding; Be provided with location-plate between drill bit and the guard ring, location-plate is that several piece is axially disposed within the strip metal plate on the drilling rod, and location-plate and drilling rod are welding; The connecting portion of drill bit and drilling rod is provided with stiffener, and stiffener and drill bit and drilling rod are welding.
The spacing of said drill bit and guard ring is 800 ~ 1000mm.
The top of said drill bit is provided with the alloy apex point.
The utility model has compared with prior art that apex point is firm, and vertical rigidity is big, and guide-localization is good, realizes that the cutting of drill bit is crept into, and better the water and soil body of reinforcing is cut and stirs, and has accelerated speed of application, further reduces construction costs.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the web structure sketch map.
The specific embodiment
Consult accompanying drawing 1 ~ accompanying drawing 2; The utility model is made up of drill bit 1, drilling rod 4, web 5 and guard ring 8; The welding of the top of drilling rod 4 is provided with the drill bit 1 of alloy apex point 11, is provided with stiffener 2, stiffener 2 and drill bit 1 and drilling rod 4 welding at the connecting portion of drill bit 1 and drilling rod 4; Stiffener 2 has been strengthened the vertical rigidity of drill bit 1, guarantees the firm of drill bit 1; Guard ring 8 is fixedly connected with drilling rod 4 with diagonal member 7 by gusset 6, and several gussets 6 are arranged on radially in the guard ring 8 and weld with drilling rod 4 and guard ring 8, and several diagonal members 7 are arranged on top and the drilling rod 4 and guard ring 8 welding of guard ring 8; Web 5 is the metal sheet of right-angled trapezium; Three alloy heads 9 of its base welding, three armpit pawls 10 of hypotenuse welding, web 5 are arranged on bottom and the drilling rod 4 and gusset 6 welding of guard ring 8; The last base of web 5 and drilling rod 4 axis are 60 ° of angle welding; Its right-angle side and gusset 6 welding, alloy cutting head 9 and the armpit pawl 10 that web 5 lower ends and side evenly are provided with improved cutting and the mixing power and the anti-wear performance of 1 pair of cement soil body of drill bit, improved rate of penetration greatly; Be provided with location-plate 3 between drill bit 1 and the guard ring 8, location-plate 3 is three strip metal plates that are axially disposed within on the drilling rod 4, and location-plate 3 is welding with drilling rod 4; Location-plate 3 has increased the weight of the deadweight of drill bit 1, prevents that drill bit about 1 is loosening, has played good guide-localization effect; Also increased simultaneously the guiding aperture, drill bit 1 is 800 ~ 1000mm with the spacing of guard ring 8, than the three-wing bit of the prior art spacing that extended; Adopt drill point to creep into certain degree of depth earlier when in cement-soil, constructing, the armpit pawl 10 that utilizes drilling rod 4 tops behind the formation space makes cement-soil become piece to drop to the incised cement-soil; The abrasive drilling of three-wing bit alloy circle is advanced to change into cutting creep into, accelerated speed of application.
More than just the utility model being further described, is not in order to the restriction this patent, and all is that the utility model equivalence is implemented, and all should be contained within the claim scope of this patent.
