Abstract
The utility model discloses a drilling tool without waste discharge for a long auger boring machine. The drilling tool comprises a drill rod core body, wherein the front end of the drill rod core body is connected with a drill bit; the back end of the drill rod core body is connected with a cylindrical drill rod without a blade; a drill rod cylinder body is connected outside the drill rod core body; a screw blade is connected outside the drill rod cylinder body; the drill rod cylinder body forms a tapered shape; the outer side of the screw blade forms a circular shape; the inner side of the screw blade forms the tapered shape; when the utility model is used for construction, soil is not required for being discharged outside the ground and the soil which is drilled by a drill bit part is gradually extruded in a soil layer at the circumference of a hole by the tapered face of the drilling tool. Thus, the soil density of the soil layer at the circumference of the hole is increased and accordingly the pressure resistance of a basal layer is increased. The utility model enhances engineering quality, simultaneously saves large manpower and machines and reduces engineering cost.
Description
Technical field
The utility model relates in the constructional engineering machinery full screw earth auger boring a kind of drilling tool under the soil layer.
Background technology
The drilling tool that known full screw earth auger adopts is a kind of cylindrical drilling tool of full helical blade type.When in soil layer, holing, need a large amount of soil is discharged ground, must soil be transported the construction plant with great amount of manpower machinery.
Summary of the invention
The purpose of this utility model is to provide a kind of full screw earth auger no casting drilling tool, and this drilling tool does not have soil and discharges when boring.
The purpose of this utility model is achieved in that this drilling tool comprises the drilling rod core body, drilling rod core body front end links to each other with drill bit, the drilling rod core back-end links to each other with the cylindrical drilling rod of on-bladed, drilling rod core body outside is connected with the drilling rod cylindrical shell, drilling rod cylindrical shell outside is connected with helical blade, the drilling rod cylindrical shell is taper, and the helical blade outside is circular, and helical blade is inboard to be taper.
During the utility model construction, soil need not be discharged ground, but the soil that the taper surface that leans on drilling tool gets out bit head presses in the soil horizon on every side of hole gradually, make the hole density of soil increase of soil layer on every side, thereby increased the compression resistance of basal layer, improve workmanship, also saved great amount of manpower and machinery simultaneously, reduced the cost of engineering.As use former full screw earth auger that the construction of casting drilling tool is arranged, and be the 600mm drilling tool with the diameter, the stake machine that bores dark 20m is an example, line-spacing and array pitch are the quincuncial pile of 2m, at 24M
2Area on 12 of drilling pouring stakes, the casting amount is 68M
3, mound such as mountain must transport the building site with soil with great amount of manpower and machinery.Use the utility model then can avoid this a large amount of soil to discharge.
Description of drawings
Fig. 1 is the structure chart of an embodiment of the present utility model.
1. drilling rod core bodys among the figure, 2. drilling rod cylindrical shell, 3. helical blade, 4. drill bit.
The specific embodiment
In Fig. 1, drilling rod core body 1 front end links to each other with drill bit 4 with bolt by flange, and drilling rod core body 1 rear end links to each other with the cylindrical drilling rod of bolt and on-bladed (not drawing among the figure) by flange.Drilling rod core body 1 outside is connected with drilling rod cylindrical shell 2, and drilling rod cylindrical shell 2 outsides are connected with helical blade 3.Drilling rod cylindrical shell 2 is taper.Helical blade 3 outsides are circular, and helical blade 3 inboards are taper.Helical blade 3 inboards are meant and drilling rod cylindrical shell 2 connections.
The outside of drilling rod core body 1 also is taper, so that be connected with drilling rod cylindrical shell 2.The seamless steel pipe of drilling rod core body 1 employing diameter 180*14 and flange and reinforcing bar are made.
Drilling rod cylindrical shell 2 end diameters are 190mm, and outside diameter is the external diameter of helical blade 3, equal diameter 600mm.The long 5m of drilling tool, so drilling rod cylindrical shell 2 taperings are about 1: 12.
On-bladed cylinder bur pole length disposes according to drilling depth, and its diameter equals the diameter of drilling rod cylindrical shell 2 big ends.
When construction, drill bit 4 pierces the stratum.Bore gradually when dark, form the hole of design aperture 600mm by taper gradually.The cylindrical drilling rod of on-bladed is twisted with the fingers light with the hole and is twisted with the fingers in fact, finishes boring work.
