Detailed description of the invention
With detailed description of the invention, this utility model is further illustrated below in conjunction with the accompanying drawings.
As shown in Figures 1 and 2, a kind of shearing resistance anchor cable described in the utility model, including cable body 1, cable body 1 includes freedom
Duan Suoti 11 and anchoring section cable body 12, also include shearing resistance steel pipe 2, and described shearing resistance steel pipe 2 is enclosed within cable body 1, and shearing resistance steel
A part for pipe 2 is enclosed within part free segment cable body 11, and the remaining part of shearing resistance steel pipe 2 is enclosed within part anchoring section cable body 12.
Wherein, so-called shearing resistance steel pipe 2, it can be common steel pipe, as long as having certain shear resistance, the most typically requires steel
The material of pipe has certain rigidity and steel pipe has certain wall thickness.Such as can be selected for the hot rolling that wall thickness is 4mm seamless
Steel pipe is as shearing resistance steel pipe 2.
When practice of construction, needing the side slope of anchoring, it includes the soft stratum being positioned at slope surface layer and is positioned at below soft stratum
Competent bed, the divisional plane between its soft stratum and competent bed is referred to as sliding surface or sliding surface.Resisting in this utility model
Shear-steel pipe 2 needs to be deep in competent bed one part just, and is placed in soft stratum by remaining part, anti-to play
Shearing action when soft stratum slides；Simultaneously as when construction, anchoring section cable body 12 is usually corresponding to competent bed,
Free segment cable body 11 is then corresponding to soft stratum, therefore when being set on cable body 1 by shearing resistance steel pipe 2, it is only necessary to by shearing resistance
A part for steel pipe 2 is enclosed within part free segment cable body 11, is enclosed within by remaining part on part anchoring section cable body 12.When
So, in theory, if working as anchoring section cable body 12 and the corresponding relation of competent bed and free segment cable body 11 and soft stratum
When corresponding relation deviation is excessive, it should using the sliding surface of actual soft stratum and competent bed as separation, and make shearing resistance steel
A part for pipe 2 is deep in competent bed, and is placed in soft stratum by remaining part.
It addition, preferably contact to ensure that shearing resistance steel pipe 2 is respectively provided with soft stratum and competent bed so that it is have preferably
Shearing resistance effect, this utility model arranges length that shearing resistance steel pipe 2 is enclosed within free segment cable body 11 further and is enclosed within anchoring section cable body
Length on 12 is all not less than 3 meters；Length that requirement shearing resistance steel pipe 2 is deep in competent bed that concrete is is the lowest 3 meters,
And the length being deep in soft stratum is also not less than 3 meters；Certainly, in shearing resistance steel pipe 2 is deep into competent bed and soft stratum
Length can equal also can not wait: such as, a length of 6 meters of shearing resistance steel pipe 2, be deep in competent bed and soft stratum
Length is 3 meters；Or a length of 8 meters of shearing resistance steel pipe 2, a length of 3 meters be deep in competent bed, and it is deep into soft
Length in incompetent beds is 5 meters.
It addition, also can be provided for returning at the bottom of hole the Grouting Pipe 3 of slurry processes grouting, and Grouting Pipe 3 is coaxial with shearing resistance steel pipe 2；
Return slurry processes slip casting at the bottom of its mesopore, referring to the bottom by Grouting Pipe 3 being deep into boring, then starting slip casting from bottom, inject
Concrete be upwards gradually increasing from foot of hole and pour.General, Grouting Pipe 3 uses common Grouting Pipe, as usedPipe is made, and i.e. can reserve slurry outlet near the one end at the bottom of hole at the end of Grouting Pipe 3, and slurry outlet can set
Put on the tube wall of Grouting Pipe 3.Grouting Pipe 3 is pulled out, to guarantee good slip casting effect on forbidding during slip casting.
It addition, on the basis of the shearing resistance anchor cable of said structure, this utility model also can farther include steelframe ring 4, steelframe ring 4
It is arranged on shearing resistance steel pipe 2 interior and coaxial with shearing resistance steel pipe 2, the circumference of steelframe ring 4 is provided with many radial directions uniformly and divides
The dowel 5 of cloth, one end of dowel 5 is connected with steelframe ring 4, and its other end is connected with shearing resistance steel pipe 2, and cable body 1 is positioned at
Between steelframe ring 4 and shearing resistance steel pipe 2, and cable body 1 is fixed with steelframe ring 4 and is connected.Steelframe ring 4 is set and connects accordingly
On the one hand the effect connecing muscle 5 can improve the shear resistance of shearing resistance steel pipe 2, on the other hand can pass through dowel 5 and steelframe ring 4 will
Shearing resistance steel pipe 2 and cable body 1 are fixedly connected with；So first shearing resistance steel pipe 2 can be fixed on appropriate location on cable body 1 in advance,
The most again cable body 1 is placed in the boring of side slope.It addition, when being provided with Grouting Pipe 3, Grouting Pipe 3 can be from steelframe ring 4
Center pass.
Concrete, above-mentioned when being provided with dowel 5 with steelframe ring 4, dowel 5 and steelframe ring 4 and with shearing resistance steel pipe 2 it
Between welding manner all can be used to be attached.
More specifically, in shearing resistance steel pipe 2, its axial direction can be provided with multiple steelframe ring 4, multiple steelframe rings 4 are to each other
Every setting, as shown in fig. 1, three steelframe rings 4 it are provided with.It addition, in the case of for arranging multiple steelframe ring 4, one
As be spaced setting uniformly along the length direction of shearing resistance steel pipe 2, and the distance typically arranging adjacent steelframe ring 4 is more than or equal to
0.5 meter.
Furthermore, it is contemplated that generally, cable body 1 is made up of many steel strand wires 6, owing to above-mentioned analysis is learnt, works as setting
When having steelframe ring 4, cable body 1 should be provided in the annular region between shearing resistance steel pipe 2 and steelframe ring 4, therefore, works as rope
When body 1 is made up of many steel strand wires 6, many steel strand wires 6 can be uniformly distributed along the circumference of steelframe ring 4, and by every
Steel strand wires 6 are all fixing with steelframe ring 4 to be connected.Fixed form as steel strand wires 6 with steelframe ring 4 can use thin wire to tie
Prick.Certainly, the quantity that steel strand wires 6 be may further be provided is identical with the quantity of the dowel 5 arranged on each steelframe ring 4,
Steel strand wires 6 are only distributed between two dowels 5 that so can be adjacent on same steelframe ring 4；Such as in Fig. 2 institute
Showing, being provided with five steel strand wires 6, be provided with five dowels 5 accordingly on each steelframe ring 4, five dowels 5 are uniform
The circumference being distributed in steelframe ring 4 on, five steel strand wires 6 are respectively placed between adjacent two dowels 5 simultaneously.
It addition, for the ease of being placed to by shearing resistance steel pipe 2 in boring, typically require that the external diameter diameter of shearing resistance steel pipe 2 is less than boring
Diameter, and typically require that distance between the outer wall of shearing resistance steel pipe 2 and the hole wall 7 of boring is not less than 3mm；It it is requirement
Boring diameter more than shearing resistance steel pipe 2 external diameter diameter 6mm and more than.Such as, use as a diameter of 146mm of boring
The hot rolled seamless steel tube of a diameter of 140mm of external diameter makes shearing resistance steel pipe 2, holes as using external diameter diameter during a diameter of 127mm
Hot rolled seamless steel tube for 121mm makes shearing resistance steel pipe 2.
The above, preferred embodiment the most of the present utility model, not in order to limit this utility model, all do not paying creation
Property work in the case of, any modification, equivalent substitution and improvement etc. done in spirit of the present utility model and principle, all should
Within being included in protection domain of the present utility model.
