Summary of the invention
The object of the invention is to solve above-mentioned the deficiencies in the prior art, providing a kind of to remove being embedded in the drilling rod of underground, drill bit or other obstruction fast, economically, ensureing the sleeve type helical stake machine drill head of foundation pile smooth construction and the construction method of rid.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of sleeve type helical stake machine drill head, it is characterized in that the upper end of sleeve is provided with flange, the lower end of sleeve is inlaid with cutter, and the outer wall of sleeve bottom is gone into battle and shown carbide alloy reaming tooth, the inwall of sleeve lower end is at least provided with two barbs tilted to sleeve axis direction.
Reaming tooth of the present invention is located at lower cartridge 1/3rd place; reaming tooth is at least provided with three rows in the axial direction, and often drain into and be provided with six reaming teeth less, reaming tooth is generally embedded on sleeve outer wall; reaming tooth can be welded in sleeve wall, plays the effect of reaming and protection sleeve wearing and tearing.
A construction method for rid,
Step one, bore stake holes, selected pile foundation position, adopt screw pile machine and tapered twist drill is fixed on the core pipe of screw pile machine through flange, augers cutter tooth is utilized to cut soil layer, after the soil body in stake holes is cut by augers, rotate outside rising tap along the core pipe with helical blade, when being drilled into obstruction, more bit change, sleeve type helical stake machine drill head is fixed on the core pipe of screw pile machine through flange, the cutter tooth of telescopic chisel edge is utilized to cut stratum or obstruction, sleeve has two aspect functions, the moment of torsion provided by top drive on the one hand and pressing-in force pass to cutter tooth, in the process of creeping into, also play supporting hole wall simultaneously, prevent the effect of hole wall collapse,
Step 3, perfusion mud, retaining wall deslagging, mud is watered by high plastic clay or swell soil and forms, and the proportion of mud is 1.1-1.3, and mud is delivered in core pipe by grout pump, part mud hangs on hole wall, reduce hole wall frictional resistance, prevent hole wall collapse, most of mud carries the soil body or the obstruction slag under cutting by outside sleeve or the space between core tube wall and hole wall upwards tap, note mud pressure is not less than 10MPa
The obstruction such as broken pile, drilling rod or drill bit in step 4, cleaning sleeve, enters in telescopic drill bit when being embedded in the broken pile of underground, drilling rod or drill bit etc. obstruction being cut,
Step 5, extract obstruction, stop perfusion mud, upwards lift lug cylindrical spiral stake machine drill head, the obstruction in sleeve is stopped by the hook of sleeve lining when sleeve type helical stake machine drill head rises, and hook blocks outside obstruction proposition hole,
The present invention have structure simple, change convenient, operating efficiency advantages of higher, be specially adapted to clear up the drilling rod, drill bit or other obstruction that are embedded in underground and remove, ensure foundation pile smooth construction.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described:
As shown in drawings, a kind of sleeve type helical stake machine drill head, it is characterized in that the upper end of sleeve 1 is provided with flange 2, the lower end of sleeve 1 is inlaid with cutter 3, the outer wall of sleeve 1 bottom is gone into battle and is shown carbide alloy reaming tooth 4, the inwall of sleeve 1 lower end is at least provided with two barbs 5 tilted to sleeve axis direction, described reaming tooth 4 is located at lower cartridge 1/3rd place, reaming tooth 4 is at least provided with three rows in the axial direction, often drain into and be provided with six reaming teeth 4 less, reaming tooth 4 is generally embedded on sleeve 1 outer wall, can be welded in sleeve wall, play the effect of reaming and protection sleeve wearing and tearing, cutter 3 and reaming tooth 4 adopt carbide alloy to make, particularly cutter 3 can cut iron and steel, rock etc.
