Description
Technical field
The present invention relates to a kind of tunnel of coal mine, tunnel and underground engineering field/tunnel breaking surrounding rock reinforcement technique, tools
Body designs a kind of positioning slip casting anchoring prestress anchor tube rope.
Background technique
The undergrounds field such as coal mine, tunnel country rock situation is complicated, and geological conditions is severe, opens especially in recent years into deeps mines
Adopt, wall rock geology situation is increasingly complex, the surrouding rock stresses such as crustal stress situation also with Subsurface country rock there are a great difference,
There is extremely broken situation in deep tunnel/tunnel surrounding, for regions such as these crushed zones, karst collapse col umns, using anchor pole, anchor cable branch
It when shield, is often not enough to play the role of stabilizing surrounding rock, therefore, the prior art also mostly uses composite support mode, such as anchor net branch
Shield, bolt-spary supports, the collaboration supporting of shotcrete pylon etc., but for the supporting inside country rock, be not further improved, ground
When getting off to press, it tends to be difficult to safeguard adjoining rock stability.
In order to improve, there are the country rock in the increasingly complex geology area such as crushed zone or karst collapse col umn is steady inside the country rock of underground
It is fixed, it is necessary to while anchor pole or cable bolting, grouting and reinforcing can be carried out to broken region, meanwhile, it also to integrate pre-
Stress overlaps supporting, and prestressing force support technology can be preferably used for underground complex surrounding rock body supporting in this way.And such as
Fruit first improves whole country rock wall-like condition using punching slip casting, then carries out the structural supports such as anchor pole or anchor cable, can bring so more
More project amounts, waste of manpower, material resources, and trivial operations, and delay the duration.
Summary of the invention
For above-mentioned technical problem of the existing technology, the present invention provides a kind of positioning slip casting anchoring prestress anchor tubes
Rope can be realized to underground engineering breaking surrounding rock band high efficiency, quick, simple supporting, and can be fine by prestressing force supporting
Supporting to complex surrounding rock on, improve inside country rock existing for complex surrounding rock state, and realize prestressing force combined supporting.
In order to solve the above technical problems, a kind of positioning slip casting anchoring prestress anchor tube Cable Structure of the invention is as follows:
Anchor tube rope includes anchor tube and anchor cable, and anchor tube is provided with supporting plate close to country rock outer end, and anchor tube end is provided with strength
Steel loop circle is arranged grouting port on the anchor tube between strong steel ring and supporting plate, the drilling inner end of anchor tube is provided with level pressure and stops
Slurry plug, anchor cable pass through strong steel ring and level pressure stop grouting plug, and foot of hole is goed deep into inner end, and anchorage head is arranged in anchor cable inner end；
Multiple through-holes are set on the anchor tube wall, setting grouting bag are surrounded outside through-hole, the grouting bag is close at the wall of a borehole
Geotextiles, the suture connection elastic capsule skin around geotextiles, and the capsule skin be fixed on around multiple through-holes it is solid with anchor tube
It is fixed to be tightly connected；Anchor cable outer end is provided with nut and carries out prestressd anchor cable anchoring；
It needs to be arranged many places through-hole in anchor tube outer wall foundation and is correspondingly arranged multiple grouting bags；
Prestressing force load is carried out using prestressd anchor cable machine；
Anchor tube rope grouting support is carried out after prestressing force load using slip casting machine.
The present invention solves the prior art and there is construction complexity, and slip casting and prestressing force load process are many and diverse, and cannot be very
Carry out positioning slip casting prestressing force loading problem well, realize quickly, facilitate construction, positioning slip casting is to progress at the zone of fracture or crack
Positioning grouting and reinforcing improves drilling country rock, and realizes prestressing force and load firm anchor tube, comes while prestressing force load real
Now position grouting and reinforcing, ensure that the firm implementation of subsequent prestressed permanent supporting and slip casting, realize it is quick, simple,
And the technical effect of grouting support country rock can be positioned very well.
Detailed description of the invention
Fig. 1 is anchor tube Cable Structure main view of the present invention.
Specific embodiment
Fig. 1 shows a kind of positioning slip casting anchoring prestress anchor tube rope, which includes anchor tube 1 and anchor cable 3, anchor cable 3
Inside anchor tube 1, anchorage head 6 is arranged in end, and through-hole 4 is arranged in the outer wall of anchor tube 1, setting slip casting is surrounded outside through-hole 4
Pouch 2, the grouting bag 2 is close to being geotextiles at the wall of a borehole, suture connection elastic capsule skin, the capsule around geotextiles
Skin be fixed on around multiple through-holes 4 and with anchor tube fixed seal connection, multiple grouting bags 2 are set on anchor tube 1, corresponding slip casting
It is country rock rupture or cranny development position at the wall of a borehole of pouch 2, when slip casting, slurries will be from the geotextiles of grouting bag 2
Locate vectored injection at crack, when grout cures, in the borehole by 1 positioning and anchoring of anchor tube, plays positioning anchor tube rope and propped up
Protect the effect of tunnel or tunnel surrounding.
The anchor tube rope stream line 3 passes through anchor tube 1 and is fixed on foot of hole by anchorage head 6, when anchor tube rope deeply drills
When middle, anchorage head 6 is rolled up the resin that foot of hole is pre-placed is stirred, and after resin volume stirs and dissipates solidification, anchor cable 3 is fixedly secured
In the borehole；The one end of anchor cable 1 outside country rock passes through the elastic strong steel ring 9 of 1 outside end of anchor tube setting, and passes through spiral shell
Mother 10 carries out preload fixation, and anchor cable 3 is carried out drawing preload by pretightening machine in tunnel or tunnel, applies prestressing force, is anchor
Rope 1 plays prestressing force support action, and passes through the prestress application of anchor cable 3, and the more strong fix of anchor tube 1 is being bored
Supporting is carried out in hole, and provides stable supporting and the fixed effect of anchor tube 1 for 1 slip casting process of anchor tube.
Anchor tube 1 still has supporting plate 7 close to country rock wall outer end, and sets on the anchor tube 1 between strong steel ring 9 and supporting plate 7
Grouting port 8 is set, the drilling inner end of anchor tube 1 is provided with level pressure stop grouting plug 5, anchor cable 3 passes through the level pressure stop grouting plug 5, when anchor cable 3 is pre-
After stress has applied, grouting equipment injects slurries in anchor tube 3 by grouting port 8, and slurries enter grouting bag 2, and are split
Gap band positioning slurries are reinforced and positioning and anchoring anchor tube 1 can choose slurries slip casting and add according to field geology conditions and supporting needs
Solid overflow degree and whether forced shock stop grouting plug 5, with decide whether further to reinforce anchor tube rope bottom hole reinforce.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
