Abstract
The utility model patent is a kind of expansion antiskid anchor pole, is made up of expansion sleeve, Grouting Pipe, shell fragment, pallet, nut, stop grouting plug, sleeve pipe pad, sleeve pipe pallet.Body of rod center is provided with elongated Grouting Pipe, and Grouting Pipe is provided with injected hole.Described jacket exterior shape is cylinder, and sleeve pipe is provided with two elongated cover pipe seams, and sleeve pipe is divided into two parts.Grouting Pipe is provided with injected hole, the Grouting Pipe between injected hole is provided with hook hole, the elastic hook on shell fragment extend in hook hole, and shell fragment and steel tube body are connected firmly; Shell fragment is provided with crimp seam and injected hole, and slurry enters anchor hole by the crimp seam on shell fragment and injected hole, makes shell fragment be placed between slurry, makes anchor pole fully fixing.This device can reach antiskid anchoring requirement, solves the problem of anchor pole anchor pole slippage in unfavorable geology.
Description
Technical field
The utility model relates to a kind of anchoring means, is specifically applied to the soil bolt of soil level sideslope or base pit engineering reinforcing.
Background technology
More and more important to the supporting of underground construction, anchor pole because of its supporting effect good, economic and practical, and by as commonly use support apparatus.In order to increase the contact force of anchor pole and country rock, improving supporting effect, having occurred various dilatancy anchor pole, but most dilatancy anchor pole, be only by the extruding country rock that expands, increase the pressure of the body of rod and country rock and play the effect increasing support anchoring power.But once anchor pole is subject to longitudinally outside pressure, and when pressure is greater than the frictional force that anchor pole provides, anchor pole will produce friction, and produce and slide, anchor pole just loses effect completely.
Summary of the invention
The utility model patent provides a kind of expansion antiskid anchor pole, and this device can reach antiskid anchoring requirement, solves the problem of anchor pole anchor pole slippage in unfavorable geology.
The utility model is a kind of inflatable antiskid anchor pole, and by expansion sleeve, steel tube body, nut, pallet, truncated cone-shaped shell fragment, stop grouting plug, sleeve pipe pad, sleeve pipe pallet forms.Described jacket exterior shape is cylinder, and interior shape matches with the antiskid shell fragment of the body of rod, and sleeve pipe is provided with two elongated cover pipe seams, and sleeve pipe is divided into two parts.Described Grouting Pipe, is characterized in that, pipe is just provided with injected hole at interval of certain distance, the steel pipe walls between injected hole is provided with truncated cone-shaped extrusion elastic, and shell fragment is provided with four slurry outlets and four crimp seams.During use, first two parts of sleeve pipe are closed up around the body of rod, then at the utility model head successively mounting sleeve pad, pallet, shim tray and nut, after installing, the utility model entirety is sent in rock body drilled, then by Grouting Pipe slip casting.After slurry reaches some strength, fastening nut, the body of rod can relative to sleeve pipe outwards movement, and in moving process, shell fragment opens, and causes casing expandable, and sleeve outer wall and rock mass produce and extrude and rub, thus reach anchoring effect.
As improvement, Grouting Pipe is provided with truncated cone-shaped shell fragment between injected hole, the angle of truncated cone-shaped shell fragment and Grouting Pipe is 5-10 degree.
As improvement, bullet is provided with crimp seam, and quantity is 4, and angle is 90 degree each other, and slurries also can flow out from deformation joint, and pulp is satisfactory for result.
As improvement, when the diameter of shell fragment is the 4-5 times of Grouting Pipe top diameter, the diameter of expansion sleeve tube wall is 5-6 times of Grouting Pipe diameter simultaneously, and expansion sleeve is provided with 2 elongated pipe seams, and angle is 180 degree each other.
The invention has the beneficial effects as follows: it is simple that this design has structure, and easy for installation, high construction efficiency rate is improved; Slip casting is carried out to anchor pole, shell fragment by slurries effect and opening, shell fragment, expansion sleeve can with solidify after slurries combine, ensure that anchor pole has good anchoring effect.

Detailed description of the invention
In Fig. 1, a kind of expansion antiskid anchor pole, by expansion sleeve 1, Grouting Pipe 11, shell fragment 2, stop grouting plug 6, pallet 7, nut 8, sleeve pipe pallet 12, shim tray 13 forms.Described sleeve pipe 1 outer shape is cylinder, interior shape matches with steel tube body 11, it is Grouting Pipe that sleeve pipe 1 is provided with two elongated cover pipe seam 14 steel tube body, in Grouting Pipe 11, each certain distance is provided with injected hole 3, Grouting Pipe 11 between injected hole 3 is provided with hook hole 10, and the elastic hook 5 on shell fragment 2 extend in hook hole 10, and shell fragment 2 and steel tube body 11 are connected firmly; Shell fragment 2 is provided with crimp seam 9 and injected hole 3, and slurry enters anchor hole by the crimp seam 9 on shell fragment 2 with injected hole 3, makes shell fragment 2 be placed between slurry, makes anchor pole fully fixing.When reinforcing use, first hole with rig, with rig, multistage shell fragment antiskid anchor pole is pushed in anchor hole, stop grouting plug 6 is installed in aperture, and slurries are injected in anchor pole, slurries flow out and are full of the hole around anchor pole from the injected hole 4 steel pipe, then slurries flow out from the crimp seam 9 shell fragment 2 with injected hole 3 again, slurries are made to be full of whole anchor hole gap, after slurry reaches some strength, fastening nut 7, Grouting Pipe 11 can relative to sleeve pipe 1 outwards movement, moving process middle sleeve 1 is squeezed and expands, sleeve pipe 1 outer wall and rock mass produce and extrude and rub, simultaneously thus reach anchoring effect.
As improvement, Grouting Pipe 11 is provided with truncated cone-shaped shell fragment 2 between injected hole 4, truncated cone-shaped shell fragment 2 is 5-10 degree with the angle of steel pipe 11.
As improvement, shell fragment 2 is provided with crimp seam 9, and quantity is 4, and angle is 90 degree each other, and slurries also can flow out from deformation joint 9, and pulp is satisfactory for result.
As improvement, when the diameter of shell fragment 2 is the 4-5 times of Grouting Pipe 11 top diameter, the diameter of expansion sleeve 1 is 5-6 times of Grouting Pipe 11 diameter simultaneously, and expansion sleeve 1 is provided with 2 elongated pipe seams 14, and angle is 180 degree each other.
