Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is elaborated:
In conjunction with Fig. 1 to Fig. 4, a kind of self-drilling type is tested oneself prestressing force by pressure grouting anchor pole, comprises the first outer tube 1, adapter sleeve 2, the second outer tube 3, inner tube 4, stop grouting plug 5, the first pallet 6, allows pressure pad 7, the second pallet 8 and prestressing force monitor ball 9. The first outer tube 1 front end sleeve is connected to drill bit 11, and drill bit 11 is convenient in the country rock of the first outer tube 1 precession tunnel outer wall. The first outer tube 1 rear end connects the second outer tube 3 by adapter sleeve 2. On described the first outer tube 1 and the second outer tube 3 outer faces, be all provided with and the suitable screw thread being connected of adapter sleeve 2, the first outer tube 1 and the second outer tube 3 are threaded connection the two ends at adapter sleeve 2. Described inner tube 4 is positioned at the first outer tube 1 and the second outer tube 3, and when combination is installed, inner tube 4 is by crossing successively the second outer tube 3 and the first outer tube 1 before backward, and inner tube 4 outer walls are connected with the second outer tube 3 inwalls. In described inner tube 4, have injected hole 41, on injected hole 41, be connected with Grouting Pipe 42. When Grouting Pipe 42 is installed in combination, Grouting Pipe 42 one end are through in adapter sleeve 2 and the rear precession injected hole 41 of the second outer tube 3. Described injected hole 41 is provided with multiple, and Grouting Pipe 42 is provided with multiple.
Described stop grouting plug 5, the first pallet 6, allow pressure pad 7, the second pallet 8 and prestressing force monitoring ball 9 be nested with in turn on the second outer tube. Stop grouting plug 5 is positioned at the first pallet 6 front ends, and stop grouting plug 5 rear end faces and the first pallet 6 front end faces join, and allows pressure pad 7 between the first pallet 6 and the second pallet 8, makes pressure pad logical 7 fastening by the first pallet 6 and the second pallet 8. The rear end face of described prestressing force monitoring ball 9 front end faces and the second pallet 8 joins, and ellipse thick in the middle of prestressing force monitoring ball 9 is is spherical. The rear end cover of described the second outer tube 3 has nut 21, and described nut 21 joins by packing ring 22 and prestressing force monitoring ball 9. Described packing ring 22 comprises steel ring and rubber ring, and described steel ring and prestressing force monitoring ball 9 join, and described rubber ring and nut 21 join, and the design of steel ring and rubber ring is to be convenient to nut 21 to fasten prestressing force monitoring ball 9. Described stop grouting plug 5 is round table-like, on described stop grouting plug 5 end faces, has stop grouting plug through hole 51.
By pressure grouting anchor pole in use, the first outer tube 1 is by drill bit 11 precession mine laneway outer walls for the utility model, and because the radius value of drill bit 11 is greater than the radius value of outer tube, the radius value of the boring that drill bit 11 gets out can be greater than the radius value of the first outer tube 1. The first outer tube 1 rear end connects the second outer tube 3 by adapter sleeve 2, and adapter sleeve 2 is positioned at boring, and inner tube 4 is positioned at the first outer tube 1 and the second outer tube 3, and stop grouting plug 5 fits tightly with the port of boring. Use mining slip casting machine, slip casting machine is connected on the inner tube slip casting port of inner tube 4 rear ends, by slip casting machine, cement mortar is injected in inner tube 4, cement mortar fills up rapidly inner tube 4 after entering into inner tube 4, because inner tube 4 is connected with Grouting Pipe 42, cement mortar gets out from Grouting Pipe 42, and the cement mortar getting out fills up boring. In the time that cement mortar fills up boring, the air in boring is discharged by the stop grouting plug through hole 51 on stop grouting plug 5, realizes slip casting fastening. In the time that STRESS VARIATION appears in tunnel, can realize the situation of change of stress by allowing pressure pad 7 realizations allow pressure, prestressing force monitor ball 9. Because this grouted anchor bar can not be extracted after using, can prevent that the grit that the boring of special soft geology structure is scattered from filling out again, greatly shorten the engineering time simultaneously.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art make in essential scope of the present utility model, also should belong to protection domain of the present utility model.
