Description
Technical field
This utility model belongs to Anchor Cable Technique field, concrete a kind of prestress anchorage cable.
Background technology
Cable bolting anchors the features such as radius is big, anchor force is strong, reinforcing scope is wide in deep excavation project with it
Slope retaining during play an important role.Cable bolting is by installing anchor cable formation anchoring in country rock
Body reinforces country rock, improves bearing capacity of the wall rock.The generally construction of anchor cable needs to carry out remote and super long distance
Deeper boring is set to install anchor cable from supporting, but at some incompact fractured surrounding rock, dead-soft rock stratum, height
When stress breaking surrounding rock and great burying coal road carry out anchor cable drilling construction, owing to country rock is loose, broken, should
The reasons such as power is big, easily occur jewel hole shut down after the phenomenon of collapse hole, cause anchor cable to install.For this kind
Situation, the most more common is bolting and grouting support, holes, anchors, the operation such as slip casting is separately carried out.But
It is that existing anchor cable easily bigger displacement and sedimentation occurs at excavation slope and Adjacent Buildings.
Utility model content
For solving the problem bigger displacement and sedimentation easily occur that existing prestress anchorage cable exists, this practicality is new
Type proposes a kind of prestress anchorage cable, and this prestress anchorage cable is flexible big, has good shock resistance and ductility, permissible
Deep-layer reinforcing, controls ground deformation simultaneously, adjusts the favourable rock stability of ground stress, be difficult to appearance
Bigger displacement and the problem of sedimentation.
The technical solution of the utility model is achieved in that
A kind of prestress anchorage cable, including anchoring section, free end and anchor afterbody, described free end by anchoring section with
Anchor afterbody couples together, and is embedded with the first steel strand wires in described free end, and described first steel strand wires scribble antirust
Described first steel strand wires are also wrapped up, the two ends rubber belt sealing of described plastic film capicitor by paint with plastic film capicitor,
Be embedded with the second steel strand wires in described anchoring section, to medium-height trestle and isolation mount, described medium-height trestle is positioned at institute
State the internal both sides of anchoring section, described isolation mount described to medium-height trestle between, described to medium-height trestle and institute
State isolation mount to be used to strut described second steel strand wires, the sheathed guiding cap in front end of described second steel strand wires,
After described guiding cap and be positioned at described anchoring section and be provided with Grouting Pipe, the front end of described Grouting Pipe offers two
To injected hole.
Further, described anchor afterbody is used for connecting waist rail, and described anchor afterbody includes stretch-draw section, anchorage and steel pad
Plate, described billet fits in described waist rail surface, and described stretch-draw section sequentially passes through described waist rail and described
Billet, is then connected with described anchorage.
Further, the front end of described Grouting Pipe is 500mm apart from the rear end distance of described guiding cap.
The beneficial effects of the utility model are,
1, anchoring section be positioned at stable Rock And Soil play provide anchor force effect, free segment be connect anchoring section
Part, not only play the effect of transmission anchor force, and anchor cable locking provided necessary elongation.Anchor
Afterbody is that pulling force is applied on waist rail or Guan Liang, makes them form a stable complex, and to pulling force
Lock, improve the globality of periphery Rock And Soil and inherent drag, increase its intensity, increase ground around
The stability of body.
2, prestress anchorage cable free segment is coated with antirust paint twice and wraps up with plastic film capicitor, two ends rubber belt sealing
In when preventing, cement grout penetrates into the plastic film capicitor of free segment, it is ensured that it will not in processing and installation process
Damage, have a water resisting property and chemical stability, and contact with cement mortar and preservative and have no adverse reaction, overlap
Cement mortar or cement paste should be filled between pipe and hole wall.
