Description
Technical field
The utility model is related to anchor cable fastening hole sealing technology fields, more particularly to one kind is in mine, tunnel, underground engineering branch
The matched hollow grouting cable anchor hole sealing device of grouting cable anchor of shield.
Background technology
The engineering reinforcement of the underground engineering that is related in geotechnical engineering field, mining engineering etc., needs to use slip casting anchor
Rope supporting.Grouting cable anchor supporting is by the injecting cement paste around grouting cable anchor cable body and cable body and being intimately associated between stratum
Mode gets up stratum consolidation, for improving the globality on stratum, plays the mechanical functions such as shearing resistance, tension, resistance to compression, so as to
The deformation on effective control stratum and stability.
In fender nude grouting and reinforcing, slurries are easy to leak out from coalmass crevasse and drilling.Sealing of hole is mainly adopted at present
With hose-rigid pipe sealing of hole, hose is arranged on anchor cable, and hose swells under the promotion of hard tube, to be blocked to drilling.But
It is not tight using hose-rigid pipe sealing of hole in the place that crack is more developed so that clearance flow between slurries are easy between cable body and hole wall
Go out, to influence the effect of grouting cable anchor supporting.
Invention content
To overcome above-mentioned technical problem, the utility model is provided and a kind of space between anchor cable and drilling can be blocked
Sternly, and the crack for the surrounding that anchor cable can be drilled blocks tight hollow grouting cable anchor hole sealing device.
To achieve the above object, the utility model is realized using following technical scheme：
A kind of hollow grouting cable anchor hole sealing device, including sealing of hole iron ring, hole packer, sealing hard tube, the sealing of hole iron ring, envelope
Hole device, sealing hard tube are sequentially arranged on anchor cable, and the sealing of hole iron ring is welded on anchor cable, and the hole packer is to be stained with cement mortar
The cloth of liquid, the hole packer can under the inhibition of the sealing of hole iron ring and it is described sealing hard tube external force push
Lower closure anchor cable drilling.
Distance of the sealing of hole iron ring apart from anchor cable drilling orifice is 400mm or more.
The utility model has the positive effect that：
The utility model is simple in structure, can block the space between anchor cable and drilling and block splitting around drilling
Gap, to improve the effect of grouting cable anchor supporting.

Fig. 2 is the structural schematic diagram of the use state of the utility model front view.
1, sealing of hole iron ring, 2, hole packer, 3, sealing hard tube, 4, anchor cable, 5, tunnel, 6, pallet,
7, lockset, 8, Anchor Agent.
Specific implementation mode
Referring to attached drawing 1,2, a kind of hollow grouting cable anchor hole sealing device, including sealing of hole iron ring 1, hole packer 2, sealing hard tube 3,
The sealing of hole iron ring 1, hole packer 2, sealing hard tube 3 are sequentially arranged on anchor cable 4, and sealing of hole iron ring 1 is welded on anchor cable 4, is played
Stop the effect of hole packer 2, hole packer 2 is the cloth for being stained with cement grout, and hole packer 2 can be made in the obstruction of sealing of hole iron ring 1
Under, and the external force of sealing hard tube 3 pushes the lower anchor cable that blocks to drill.Hole packer 2 is under the promotion of sealing of hole hard tube 3, hole packer 2
It is compressed in 1 outside of sealing of hole iron ring, what hole packer 2 was extruded is close to anchor cable drilling, and the cement grout being stained on hole packer 2 flows to anchor
Inside the crack in cable drilling hole.Hole packer 2 not only blocks the space between anchor cable 4 and anchor cable drilling sternly, but also anchor cable is drilled
The crack of surrounding blocks sternly, is not in spillage phenomenon
To improve sealing of hole effect, by the setting of hole packer 2 apart from lane side remote position, to avoid lane side detrition
Surface, by test of many times, the final distance for determining sealing of hole iron ring 1 apart from anchor cable drilling orifice is 400mm or more.
The operation principle of the utility model is as follows：
When the utility model is used, sealing of hole iron ring 1 is welded on anchor cable 4 according to the position to be sealed, Anchor Agent 8 is sent
Enter into the drilling on tunnel 5, and Anchor Agent is waited for while Anchor Agent 8 is sent to foot of hole with 4 side of anchor cable stirring Anchor Agent 8
After 8 consolidations, hole packer 2, sealing hard tube 3, pallet 6 are sleeved on anchor cable 4 successively, pallet 6, sealing are then pushed by lockset 7
Hard tube 3, hole packer 2 are moved to sealing of hole iron ring 1, and hole packer 2 is extruded in 1 outside of sealing of hole iron ring, 2 quilt of hole packer by sealing hard tube 3
What is squeezed is close to anchor cable drilling, and the cement grout being stained on 2 cloth of hole packer flows to inside the crack of anchor cable drilling.When waiting for one section
Between, carry out hollow slip casting after the crack in tunnel 5 reaches full growth.
