Description
Technical field
The utility model is related to a kind of work transmission line ground auger, particularly one kind can continue ground auger.
Background technology
Ground auger is the instrument commonly used in work transmission line construction, and conventional ground auger structure is as shown in figure 1, by drilling rod 1, draw
Ring 2, helical blade 3 are welded, and pierce underground vertically during use, draw ring bassets for anchoring wire.However, according to rule
Model requirement, the bracing wire for acting on draw ring are generally no greater than 45 ° to ditch, therefore during bracing wire is tightened up, ground auger is born simultaneously
Bracing wire moisture component and vertical stress component, ground auger can be offset to stress side, because drill pipe diameter is smaller, drilling rod top often by stretch bending,
Cause to screw out difficulty, need to align after use, reduce drilling rod intensity, add potential safety hazard.Simultaneously as ground auger withdrawal resistance by
Geology influence is very big, and conventional ground auger length is fixed, and withdrawal resistance difference is huge under different geology, and versatility is poor.
The content of the invention
The purpose of this utility model is to provide one kind according to the deficiencies in the prior art part and avoid stretch bending drilling rod, ensure
Drilling rod intensity, the ground auger that continues for improving security, being applicable a variety of different geology.
The purpose of this utility model is realized by following approach：
One kind can continue ground auger, include drilling rod and the helical blade installed in drilling rod tail end, and its structural feature is,
Also include junction structure, the drilling rod includes that ground auger buries section and ground auger continues section, and ground auger buries the upper end and ground of section
The lower end for boring the section that continues respectively is welded with a butt joint, and two butt joint cross-sectional configurations are identical；The junction structure includes biography
Moving sleeve and joint coupling, the butt joint of the lower end of drive socket socket ground auger buries the upper end of section and ground auger continues section,
Now two butt joints connect in drive socket to contacting；Drive socket is embedded in joint coupling, the section of joint coupling and brill
Bar is consistent.
In use, selection is adapted to the ground auger of length to bury section, then ground auger section and the ground auger section that continues that buries is respectively connected to
Cover in the junction structure connected, complete to be fastenedly connected, then can bore ground.The utility model employs the special knot that continues of double sets
Structure, it can be ensured that the intensity of drilling rod, at the same time it can also the different choice different length according to geological conditions ground auger bury section and
The ground auger section that continues is continued, so as to meet the needs of a variety of geology.In addition, the ground auger bending strength height that continues, has
Drilling is quick, it is reliable to continue, and is convenient to mount and dismount, the advantages that uplift force is big, strong applicability.
The utility model is specially further：
Also include anchoring sleeve, include sleeve body and hangers, sleeve body is a kind of hollow steel pipe, can be socketed
In drilling rod upper end, hangers is steel plate composition of two block weldings on sleeve body outer peripheral face, and a through hole is provided with the steel plate.
Anchoring sleeve is used to connect anchoring wire, and now the pulling force of anchoring wire acts on and anchoring sleeve first, Ran Houcai
It is drilling rod, can so effectively improves the bending strength of drilling rod, avoid stretch bending drilling rod, improves security performance, while can be no longer
Draw ring is set, and reserves the joint for being easy to bore ground.
A joint is welded with the continue upper end of section of ground auger, and the joint and ground auger bury the upper end of section and ground auger continues
The butt joint of the lower end of section uses the cylindrical configuration of regular hexagonal section.
Ground auger continue section upper end set regular hexagon joint, be to be able to preferably by ground auger pierce ground, need
Coordinate special ground auger spanner, i.e., the middle spanner for inscribed regular hexagon through hole, brill ground speed can be improved.
In summary, the utility model provides one kind and can continued ground auger, and drilling rod bending strength is high, through field test, 7t
Uplift force is not also bent, and using the special ground auger spanner of configuration, is screwed in, is screwed out conveniently；Using the junction structure of particular design, ground
Brill can be flexibly continued according to different geology to meet that bracing wire anchoring requires, suitable for various geology.The utility model is applied successfully
In Huainan-Nanjing-bid section of Shanghai AC extra high voltage engineering circuit engineering the 8th, through verifying on the spot, withdrawal resistance reaches more than 5t, has
Drilling is quick, it is reliable to continue, and is convenient to mount and dismount, the advantages that uplift force is big, strong applicability.
