Description
Technical field
The utility model belongs to Geotechnical Engineering field, is related to the anchor pole that a kind of anchoring slight slope is used, is particularly used for
Soft soil foundation slope project supporting, can increase anchor force, increase the safety coefficient of Stability of Earth Slopes.
Background technology
In slope support engineering in recent years, soft soil foundation is more and more, and soft soil slope support engineering is also just continuously increased.Institute
Weak soil is called, refers to that natural void ratio is more than or equal to 1.0 and natural moisture content is more than the fine grained soil of liquid limit.This kind of native point is
Internal friction angle and cohesive strength all very littles of the soil body, are easily deformed, liquefy, and very big difficulty is brought to engineering support design and construction,
The difficulty and cost of supporting are increased considerably.Cause the Engineering Projects of bury Engineering anchor rod supporting failure a lot, mainly
Bury anchor force is not enough caused.The anchor force of anchor pole how is improved, increases reliability, and does not increase substantially engineering and make
Valency is very urgent demand.What anchor pole used at present, generally reinforcing bar or steel wire strand were constituted, by Grouting Pipe and anchor
Muscle is combined, and is put into the hole being drilled, then slip casting.Also what is had is designed as hollow steel pipe form, from steel pipe
Middle slip casting, clay soils big to rock or internal friction angle, that cohesive strength is big are preferable.But the effect to weak soil is just very poor.
The content of the invention
The purpose of the utility model is a kind of anchor pole used in soft clay foundation of design, to increase frictional force, is increased
The breakout capacity of anchor pole.Realize that the purpose of this utility model is adopted the technical scheme that：A kind of software rhizoma nelumbinis shape anchor pole, including
There are dowel and grout pipe, it is characterised in that：The end of dowel is fixed with end fixed body, and geotechnological cloth bag is by dowel and grouting pipe sleeve
Load, the diameter of geotechnological cloth bag is gradually increased by head end to end, the end of geotechnological cloth bag is with end larynx hoop banding in end
On fixed body, the grout outlet of grout pipe is located in the end of geotechnological cloth bag, and the head end of dowel and grout pipe is provided with head end fixed body
Dowel and grout pipe are fixed, the head end of geotechnological cloth bag utilizes head end larynx hoop banding on head end fixed body, geotechnological cloth bag
The fastening straps order ascending according to diameter is fixed on geotechnological cloth bag by head end to end direction, the spacing root of fastening straps
Determined according to anchor force is calculated.
The utility model can significantly improve anchor force of the anchor pole in bury, because anchoring body regular shape so that
Reliability is increased substantially.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, 1, end fixed body；2nd, end larynx hoop, 3, geotechnological cloth bag；4th, fastening straps；5th, dowel；6th, grout pipe；7th, it is first
Hold larynx hoop；8th, head end fixed body；9th, grout outlet.
Embodiment
Referring to the drawings, a kind of software rhizoma nelumbinis shape anchor pole, includes dowel 5 and grout pipe 6, it is characterised in that：The end of dowel 5
End is fixed with end fixed body 1, and geotechnological cloth bag 3 loads 6 sets of dowel 5 and grout pipe, the diameter of geotechnological cloth bag 3 by head end to
End gradually increases, and the end of geotechnological cloth bag 3 is with the banding of end larynx hoop 2 on end fixed body 1, and the grout outlet 9 of grout pipe 6 is set
In the end of geotechnological cloth bag 3, the head end of dowel 5 and grout pipe 6 is consolidated dowel 5 and grout pipe 6 provided with head end fixed body 8
Fixed, the head end of geotechnological cloth bag 3 is using the banding of head end larynx hoop 7 on head end fixed body 8, and geotechnological cloth bag 3 is by head end to end direction
Fastening straps 4 are fixed on geotechnological cloth bag 3 according to the ascending order of diameter, the spacing of fastening straps 4 is according to calculating anchor force
It is determined that.
Structure design of the present utility model is such：The geotextiles of cylindrical shape are made in the sufficiently large geotextiles of use intensity
Bag 3, the diameter of geotechnological cloth bag 3 is gradually increased by head end to end, and the property of diameter anchor force as needed and soil is determined, soil
Work cloth intensity is sufficiently large, permeable, but impermeable slurry.In the longitudinal direction, setting fastening straps 4 spaced apart, the material of fastening straps 4
Material is identical with geotextiles, and thickening becomes band.Fastening straps 4 are processed circlewise, are pasted onto with seccotine on geotechnological cloth bag 3, or
Fastening straps 4 and geotechnological cloth bag 3 are sewed in one.The diameter of fastening straps 4 is gradually increased from head end to end, geotechnique is fixed on
On cloth bag.Dowel 5 is together with the colligation of Grouting Pipe 6.At the two ends of dowel 5, set end fixed body 1 and head end fixed body 8 with
Fixed geotechnique's cloth bag 3, end fixed body 1 and head end fixed body 8 are cylindrical, and centre is respectively provided with groove, is easy to be caught in larynx hoop
Wherein, fixed body diameter is less than the diameter of geotechnological cloth bag, puts anchor hole into facilitate and is defined.Geotechnological cloth bag 3 is used into the He of end larynx hoop 2
Head end larynx hoop 7 is fixed on head end fixed body 8 and end fixed body 1.The anchor pole made is put into hole, in place after, pass through
Grouting Pipe slip casting, under the effect of slip casting pump pressure, from end grout outlet enters cloth bag, slurries progressively fill geotechnological cloth bag simultaneously
Draining, because pressure field is, close to uniform, so slurries will form the cylinder of almost symmetry, to wrap when bag is full of
Dowel.In the presence of bunching ring, the anchoring body diameter near fastening straps diminishes, and so allows for anchoring body and uniformly wraps anchor
Muscle, and rhizoma nelumbinis shape structure is formed, because the diameter of fastening straps is become larger by head end to end, taper is formed, is thus increased
Anchor force.Because foundation soil is weak soil, easily by compression, so this anchor pole is adapted to soft clay foundation.
In use, process geotechnological cloth bag 3 first, require to determine the straight of the length of anchoring section and anchoring body according to anchor force
Footpath, the length and anchoring section of geotechnological cloth bag 3 is essentially identical, and diameter is gradually increased by head end to end.By head end to end direction
Fastening straps 4 are fixed on geotechnological cloth bag in proper order according to diameter is ascending, the spacing of fastening straps 4 is true according to anchor force is calculated
It is fixed.End fixed body 1 and head end fixed body 8 are fixed on dowel 5, the geotechnological cloth bag two ends end larynx of fastening straps is installed
Hoop 2 and head end larynx hoop 7 are fixed on end fixed body 1 and head end fixed body 8.Grout pipe 6 is solid through head end fixed body 8 and dowel
It is scheduled on together, grout outlet is in geotechnological cloth bag 3 close to the end of dowel 5.Anchor hole is bored according to design requirement on soft soil foundation, will be added
The good dowel 5 of work is sent into anchor hole, is in the milk after installing block section by grout pipe 6, in the case where slip casting pump pressure is acted on, slurries from
Grout outlet 9 is entered in geotechnological cloth bag, fills geotechnological cloth bag since end in the presence of grouting pressure, extruding weak soil is side by side
Moisture removal, under the constraint of geotechnological cloth bag, gradually forms taper anchoring body.Then anchor is installed according to normal dowel construction method
Head.
