The utility model relates to a kind of layering soil compaction drilling rod, comprise polish drill rod, described polish drill rod (1) top is provided with the flange (2) be connected with unit head, there is Reducing screw drilling rod (4) polish drill rod (1) bottom by Flange joint, there is augers (3) described Reducing screw drilling rod (4) bottom by Flange joint, described Reducing screw drilling rod (4) is made up of the cone spiral vane one (5) of symmetry and cone spiral vane two (6), the diameter of described cone spiral vane one (5) becomes large clockwise gradually bottom Reducing screw drilling rod (4) body to middle part, the diameter of described cone spiral vane two (6) oppositely diminishes gradually to top in the middle part of Reducing screw drilling rod (4) body.This drilling rod neither needs outwards to fetch earth, and turn improves the collateral resistance of pile body and the bearing capacity of inter-pile soil, significantly improves speed of application and benefit and environmental protection, therefore has wide market prospects.

Description

A kind of layering soil compaction drilling rod
Technical field
The utility model relates to pile driving equipment, especially a kind of layering soil compaction drilling rod.
Background technology
In current pile foundation industry construction, long screw drill rod used is generally provided with isometrical helical blade, when drilling rod creeps into downwards, earth in stake brings to outside stake by helical-blade sector-meeting, thus formation stake holes, but need grain bin to put place and outward transport due to earth in a large amount of stakes, affect construction speed, collateral resistance is reduced to unsaturated soil simultaneously.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of rational in infrastructure, novel in design, without the need to the layering soil compaction drilling rod fetched earth.
The technical solution of the utility model is: a kind of layering soil compaction drilling rod, comprise polish drill rod, it is characterized in that: described polish drill rod top is provided with the flange be connected with unit head, there is Reducing screw drilling rod polish drill rod bottom by Flange joint, and there is augers described Reducing screw drilling rod bottom by Flange joint.
Described Reducing screw drilling rod is made up of the cone spiral vane one of symmetry and cone spiral vane two, the diameter of described cone spiral vane one becomes large clockwise gradually bottom Reducing screw drilling rod body to middle part, the diameter of described cone spiral vane two oppositely diminishes gradually to top in the middle part of Reducing screw drilling rod body, the helical blade diameter in the middle part of described Reducing screw drilling rod body and the helical blade equal diameters of augers.
The section of the helical blade on described Reducing screw drilling rod and the helical blade on augers is hollow rectangular structure.
The thickness of described Reducing screw blade is 6-10cm.
The helical blade in described Reducing screw drilling rod stage casing is provided with semilune projection.
The utility model improves current long screw drill rod, by arranging symmetrical cone spiral vane on drilling rod, both ensure that the normal construction of a machine, do not need again outwards to fetch earth, improve the collateral resistance of pile body and the bearing capacity of inter-pile soil, significantly improve speed of application and benefit and environmental protection, therefore this layering soil compaction drilling rod has the wide market space.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model layering soil compaction drilling rod;
Fig. 2 is the cross-sectional view in the utility model layering soil compaction drilling rod stage casing.
Detailed description of the invention
A kind of layering soil compaction drilling rod, as Fig. 1, shown in 2, comprise polish drill rod, described polish drill rod 1 top is welded with the flange 2 be connected with unit head, polish drill rod 1 bottom is by Flange joint Reducing screw drilling rod 4, described Reducing screw drilling rod 4 bottom is by Flange joint augers 3, described Reducing screw drilling rod 4 is made up of the cone spiral vane 1 of symmetry and cone spiral vane 26, the diameter of described cone spiral vane 1 becomes large clockwise gradually bottom Reducing screw drilling rod 4 body to middle part, the diameter of described cone spiral vane 26 oppositely diminishes gradually to top in the middle part of Reducing screw drilling rod 4 body, the helical blade equal diameters of cone spiral vane diameter and augers 3 in the middle part of described Reducing screw drilling rod 4 body.
The section of the helical blade on described Reducing screw drilling rod 4 and the helical blade on augers 3 is hollow rectangular structure.
The thickness of described Reducing screw blade is 8cm.
Described Reducing screw drilling rod 4 stage casing is provided with semilune projection 7.
The operating principle of the utility model layering soil compaction drilling rod is: the unit head flange 2 at polish drill rod 1 top being arranged on a machine carries out turning clockwise drilling construction, after drilling rod enters soil layer, augers 3 bottom it carries out portion extrusion and creeps in stake, the remaining soil formed in its drilling process upwards transfers to the bottom of cone spiral vane 1 along with helical blade, the remaining soil of a part is attached to bottom helical blade being delivered to cone spiral vane 26 after cone spiral vane 1 clockwise layering extruding, cone spiral vane 26 is the raw downward squeezing action of local products more than reverse thread upwards transmits cone spiral vane 1, then extruded remaining soil is expressed in hole wall by the semilune projection 7 of Reducing screw drilling rod 4 stage casing welding, more than another part, soil is deposited on the bottom of cone spiral vane 1, when drilling rod turn clockwise pull up time, carrying out layering by augers 3 to it is expressed in hole wall, the remaining soil on cone spiral vane 26 pairs of drilling rod tops carries out layering back-pressure simultaneously, be delivered to Reducing screw drilling rod 4 stage casing downwards, finally realize zero to fetch earth pile.
The above; be only the utility model preferably detailed description of the invention; but the utility model protection domain is not limited thereto, is equal to according to the technical solution of the utility model and inventive concept thereof and replaces or change, all should be encompassed within protection domain of the present utility model.
