Specific embodiment
Technical solution of the present invention is described further below in conjunction with attached drawing.
As shown in Figure 1, Figure 2 and Figure 4, the Counterboring apparatus of a kind of pile body of the invention and the disposable pile of pile cover, including stake
Machine 1, stake machine crossbeam 2, attachment base 3, revolution case 4, hydraulic motor 5, pivoting support 6, reaming bit 7, pressurization oil cylinder 8, articulated slab
9, drilling rod 10, power head 11, reaming bit 7 are hollow, i.e., are cavity inside it.Stake machine crossbeam 2 is arranged on stake machine 1, and 2
Attachment base 3 is connect with stake machine crossbeam 2 using flange bolt respectively, and setting pressurization 8,2 attachment bases 3 of oil cylinder can divide on attachment base 3
Not She Zhi a pressurization oil cylinder 8, the two sides of revolution case 4 are welded with articulated slab 9, and pressurization oil cylinder 8 and articulated slab 9 are with wearing pin connection；
The side of revolution case 4 is equipped with hydraulic motor 5, and pivoting support 6 is arranged in the lower end of revolution case 4, and pivoting support 6 passes through flange reaming
Drill bit 7 with connect.Drilling rod 10 passes through the cavity of reaming bit 7, and reaming bit 7 and drilling rod 10 are coaxial, and drilling rod 10 can be band spiral shell
Line casting blade, it is also possible to solid soil shape of threads, drilling rod 10 is connect with power head 11.
Further scheme the most of the invention, reaming bit 7 is that helical blade is welded and fixed with central tube, inside central tube
For cavity, helical blade can be 3 helical structures, as shown in Figure 2 and Figure 4.
When work of the invention, passes through pressurization oil cylinder 8 and hydraulic motor 5 is driven to rotate, hydraulic motor 5 drives revolution 4 He of case
Pivoting support 6 works, so that reaming bit 7 be made to be rotated down, forms pile cover 13；Drilling rod 10 is driven to rotate by power head 11.
Reaming bit 7 of the invention and drilling rod 10 can simultaneously rotary work can also independent rotary work, the soil body is either in tap
The soil body in compacted hole forms up big and down small variable cross-section pile cover open-hole.After reaching the stake depth of design, in the mistake for promoting drilling rod 10
Cheng Zhong, the concrete perfusion in time under the promotion state in revolution, and concrete filling is carried out to open-hole, form 13 He of pile cover
Screw thread pile body 12, as shown in figure 3,12 primary concreting pile of pile cover 13 and screw thread pile body in this way, pile cover 13 and screw thread pile body 12
Seamless connection, globality are more preferable.
The invention also discloses a kind of methods of pile body and the disposable pile of pile cover, comprising the following steps: drilling rod 10 is located at
