Groove is placed in fixed plate, and and supporting plate on connection hole slot one_to_one corresponding, fastening bolt is placed in fixing slot.
During use, first by rig, country rock is carried out bore operation, then by hollow shaft and anchor head precession
In boring, the design of described protective cover, it is possible to prevent during hollow shaft is deeply holed, fluid hole
Blocked by mud, affect the injection of cement grout.Then use supporting plate to be fixed by hollow shaft, liquid will be gone out
Connector on the inner tube other end and outside slip casting machine connect, and cement grout can constantly enter into out in liquid
In pipe, along with being on the increase of the cement grout gone out in liquid inner tube, can from spout out, now cement grout
Being collected in the cavity between hollow piston and hollow shaft, now, workman only need to pull out liquid inner tube, will
Going out liquid inner tube to pull out from hollow shaft, along with going out liquid inner tube pulling in hollow shaft, hollow shaft leads to
Crossing fixed cover pulls stay column to move, and stay column stress pulls protective cover to pull open from fluid hole, and now fluid hole is i.e.
Can open, along with going out pulling of liquid inner tube, the hollow piston in going out liquid inner tube moves to first fluid hole
When, cement grout can enter in boring from the cavity between hollow piston and hollow shaft,
And then the tomography in country rock can be carried out slip casting operation, constantly pull out from hollow shaft along with going out liquid inner tube,
Successively the Paraclase in country rock can be carried out slip casting, in actual use, by constantly adjusting
The position of hollow shaft in liquid inner tube, it is possible to the Paraclase of country rock is carried out repeatedly slip casting, described in go out in liquid
Pipe and the Combination Design of hollow shaft, it is possible to be prevented effectively from the generation of the problems such as hollow grouting anchor slip casting is discontented,
Improve the effect of bolt grouting supporting.After slip casting, it is possible to use fastening bolt sequentially passes through fixing slot
With connection hole slot, fixed plate is fixed on supporting plate, uses stop grouting plug to block the other end of hollow shaft,
When needed, by fastening bolt, fixed plate and supporting plate can be separated easily, make stop grouting plug therefrom
Pull out in the middle part of empty shaft, it is simple to carry out mending slurry operation.
Beneficial effect
One, simple in construction, convenient use.
Two, with low cost, it is easy to promote.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of a kind of down-hole of the utility model country rock tomography grouted anchor bar
In accompanying drawing
Wherein part is: anchor head (1), spout (2), protective cover (3), stay column (4), fixed cover (5),
Fluid hole (6), goes out liquid inner tube (7), supporting plate (8), connector (9), fastening bolt (10), stop grouting plug

Detailed description of the invention:
When the utility model one down-hole country rock tomography grouted anchor bar is achieved in that use, first by
Rig carries out bore operation to country rock, in then hollow shaft (16) and anchor head (1) precession being holed, and institute
State the design of protective cover (3), it is possible to prevent during hollow shaft (16) deeply boring, fluid hole
(6) blocked by mud, affect the injection of cement grout.Then use supporting plate (8) by hollow shaft (16)
Fix, the connector (9) on liquid inner tube (7) other end will be gone out and outside slip casting machine connects, cement
Slurries can constantly enter into out in liquid inner tube (7), along with the cement grout gone out in liquid inner tube (7) not
Break and increase, can from spout (2) out, now cement grout is collected at hollow piston (17) and hollow shaft
(16) in the cavity between, now, workman only need to pull out liquid inner tube (7), will go out liquid inner tube (7) from
Pull-out in hollow shaft (16), along with going out liquid inner tube (7) pulling in hollow shaft (16), hollow
Shaft (16) pulls stay column (4) mobile by fixed cover (5), and stay column (4) stress pulls protective cover (3)
Pulling open from fluid hole (6), now fluid hole (6) can be opened, along with going out pulling of liquid inner tube (7),
When the hollow piston (17) gone out in liquid inner tube (7) moves to first fluid hole (6) when, cement
Slurries can enter in boring from the cavity between hollow piston (17) and hollow shaft (16),
And then the tomography in country rock can be carried out slip casting operation, along with going out liquid inner tube (7) constantly from hollow shaft (16)
Middle pull-out, can carry out slip casting, successively in actual use, by not to the Paraclase in country rock
Break and adjust the position of hollow shaft (16) in liquid inner tube (7), it is possible to the Paraclase of country rock is carried out many
Secondary slip casting, described in go out liquid inner tube (7) and the Combination Design of hollow shaft (16), it is possible to be prevented effectively from hollow
The generation of the problems such as grouted anchor bar slip casting is discontented, improves the effect of bolt grouting supporting.After slip casting, can
To use fastening bolt (10) sequentially pass through fixing slot (13) and connect hole slot (15), by fixed plate (12)
It is fixed on supporting plate (8), uses stop grouting plug (11) to block the other end of hollow shaft (16), when needing
The when of wanting, fastening bolt (10) can be passed through easily fixed plate (12) and supporting plate (8) are separated,
Make stop grouting plug (11) from the pull-out of hollow shaft (16) middle part, it is simple to carry out mending slurry operation.
