Description
Technical field
The utility model relates to civil construction equipment technical fields, only starch more particularly, to a kind of non-bonding prestress tendon
The protective device of ring.
Background technique
In the engineering constructions such as water conservancy and hydropower, highway, railway, municipal administration, to ensure adjoining rock stability and construction safety, in geology
When the engineering excavations supporting constructions such as the underground chamber (workshop) of complicated condition, High Slope Protection, prestress anchorage cable skill can be used
Art, by anchor cable apply prestressing force, active control Rock And Soil deformation, adjust Rock And Soil stress state, it is ensured that Rock And Soil it is steady
It is qualitative.In the similar engineering of the engineering excavations supporting constructions such as previous underground chamber (workshop), High Slope Protection, especially without viscous
When tying construction prestressed cable, Anchoring part slurry stop easily ruptures in prestress anchorage cable installation process due to rubbing, colliding,
Common slurry stop is not due to having safeguard measure, easily rupture gas leakage, additionally, due to inflated rubber capsule is used merely, with hole
Friction is small between wall contact surface, is influenced by grouting pressure, is easy to spillage, anchor cable grouting quality cannot be guaranteed, and then lead
Design requirement cannot be reached by causing the effect of prestress anchorage cable, be unfavorable for the engineerings such as current water conservancy and hydropower, highway, railway, municipal administration and built
Demand of the facility work to quality and economic benefit.
Utility model content
The purpose of this utility model is intended to overcome the shortcomings of the prior art, provides a kind of non-bonding prestress tendon
The protective device of grout stop.To improve shock resistance, frictional behaviour, increase itself and duct inner wall contact area, further improves and stop
Starch effect.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions:
A kind of protective device of non-bonding prestress tendon grout stop, tube body when including using in anchor cable hole, two
The annulus for being respectively arranged at tube body both ends, extending radially out is set on tube body, the rubber tyre with air inflation nozzle, is connected to
Inflated hose on air inflation nozzle is filled in the intracorporal filled layer of pipe, and is set on rubber tyre outer wall, is elastic fabric by elastic force
At elastic ring；The outer diameter of the annulus is less than the aperture of anchor cable hole.
Preferably, the outer diameter of the annulus is less than the aperture 6cm of anchor cable hole.
Preferably, the filled layer uses Anchor Agent or cement slurry.
Preferably, the length of the tube body is 11cm, wall thickness 2mm.
Preferably, the elastic ring with a thickness of 2mm, width 8cm, Zhou Changwei 52cm.
Compared with prior art, the utility model has the advantages that
1, the utility model can shift to an earlier date processing factory's production or external processing, simple process are quickly and expediently installed.
2, the utility model crocking resistance is good, larger with hole wall contact surface frictional force, and only slurry effect is good, can effectively improve
Grouting quality.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it can also be obtained according to these attached drawings other attached drawings.
Fig. 1 is that the utility model is installed on the structural schematic diagram in anchor cable hole.
Fig. 2 is the schematic cross-sectional view of Fig. 1.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are under that premise of not paying creative labor
Every other embodiment obtained, fall within the protection scope of the utility model.In the following description, in order to clearly demonstrate originally
The structure and working method of utility model will be described on the basis of attached drawing by many Directional words, but should be incited somebody to action
The Word Understandings such as "front", "rear", "left", "right", "upper", "lower" are not construed as word of limitation for convenience of term.
The protective device of non-bonding prestress tendon grout stop shown in Fig. 1-2, it is characterised in that: be located at anchor when including using
Tube body in rope hole 1, two are respectively arranged at tube body both ends, the annulus extended radially out 4, are set on tube body, have inflation
The rubber tyre 3(of mouth 5 bears maximum gas pressure 260Kpa), the inflated hose 6 being connected on air inflation nozzle 5 is filled in that pipe is intracorporal to be filled out
Layer 7 is filled, and is set on 3 outer wall of rubber tyre, the elastic ring 2 made of elastic force elastic cloth；The outer diameter of the annulus 4 is less than anchor
The aperture in rope hole 1.
Particularly, the inner ring of the annulus 4 and the same diameter of steel pipe, outer diameter is less than the aperture 6cm of anchor cable hole 1, using welding
It is connect with tube body, it is clear that bonding or threaded connection etc. can also be used.
Particularly, the filled layer 7 uses Anchor Agent or cement slurry.
Particularly, the length of the tube body is 11cm, wall thickness 2mm.
Particularly, the elastic ring 2 with a thickness of 2mm, width 8cm, Zhou Changwei 52cm；, the specific ginseng of elastic ring
Number must be determined according to grout stop size and the test of the slackness of elastic force elastic cloth, it is ensured that it is elastic moderate, if being sewn into ring size mistake
It is small, then heaving for inflated rubber capsule is limited, makes slurry stop that can not play a role；If it is excessive to be sewn into ring size, air bag fills
After gas, elastic force elastic cloth can not all stretch, can not gap between pressure bladder and hole wall there are buckling phenomena.
In the establishment of non-bonding prestress tendon cable body, protective device is through between cable body Anchoring part and tensioning section, is protected
Protection unit is fixed on anchor cable using Anchor Agent (or cement slurry) plus cotton yarn, after cable body is installed in place and fixes, by prolonging
The inflated hose extended to outside anchor cable hole is inflated to inflated rubber capsule, and the blowing pressure is not more than 260Kpa, so that air bag is heaved completely,
Elastic force elastic cloth and anchor cable hole wall completely attach to, and then tighten inflated hose, are finally in the milk using grouting equipment by anchoring section
Pipe fills the water (water injection pressure is not more than 200 Kpa) to verify the sealing effect of protective device, effectively to solve tradition to anchoring section
The problems such as easily rupturable gas leakage of slurry stop, spillage.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
