It in aforementioned self-test anchor pole, is distributed along its length on the outside of anchor head and is provided with multiple sets of teeth block, every group of tooth block includes
Multiple tooth blocks along the distribution setting of anchor head circumferencial direction；
In aforementioned self-test anchor pole, totally three groups of the tooth block, every group of tooth block includes four and is set along the distribution of anchor head circumferencial direction
The tooth block set；
In aforementioned self-test anchor pole, one end of the anchor head is provided with alloy cone cap, and the both ends of anchor head are both provided with interior
The bottom of the link slot of screw thread, alloy cone cap is provided with externally threaded connecting pin, and alloy cone cap and anchor head one end pass through company
It connects end and link slot is threadedly coupled, the front end of anchor pole is connected and fixed also by the link slot of external screw thread and the anchor head other end；
In aforementioned self-test anchor pole, the backing plate is arc billet, and backing plate is by screwing the nut being set on the outside of backing plate
Hold out against the outside for being set to stop grouting plug.
Its application method is as follows：
Using drill hole of drilling machine mode, drill on spacious exposed rock mass, hole is longer than the length of anchor pole, aperture more than at
Type bolt diameter；
Molding anchor pole is squeezed into anchor hole again, reserved 15 to 30 centimeters of anchor pole, then passes through high pressure outside anchor hole
The concrete mortar being stirred is pressed into anchor road gap by pneumatic mortar machine, while blocking anchor hole with stop grouting plug, and pays attention to that duct is discharged
Interior gas, last tightening nut wait for concrete mortar solidification；
After concrete mortar reaches intensity, wave detection analysis instrument is installed in anchor pole tail portion, by being sent out in anchor pole tail portion
Longitudinal wave makes it be propagated in anchor pole, and after wave is by potsherd and sheet rubber, wavelength and velocity of wave can change and carry out anti-
It penetrates, the back wave received is analyzed by wave detection analysis instrument, you can determine the effective length of anchor pole and whether occur
It destroys.
Compared with prior art, sheet rubber and potsherd is arranged in the utility model in anchor head, in use, only need to by
Anchor pole tail portion excites longitudinal wave, and the longitudinal wave of transmission is generated in anchor pole, can generation rate when longitudinal wave encounters potsherd and sheet rubber
And the variation of wavelength, and reflected, while longitudinal wave monitor being installed in anchor pole tail portion, the variation of longitudinal wave is analyzed, from
And judge that anchor pole gos deep into effective length and whether there is or not destructions such as fracture, torsions, the drawbacks of capable of effectively avoiding conventional anchor, and use
Convenient, cost is relatively low, suitable for promoting and applying.
Description of the drawings
Fig. 1 is the structural schematic diagram (anchor head of front end is divided into sectional view) of the utility model.
Specific implementation mode
It, below will be by attached drawing to utility model to keep the purpose of this utility model, technical solution and advantage clearer
It is described in further detail.
Embodiment：
Referring to Fig.1, the present embodiment provides a kind of self-test anchor pole, including anchor head 1, anchor pole 2 and stop grouting plug 3, anchor head 1 is alloy
