Description
Technical field
The invention belongs to Geotechnical Engineering field, is related to the anchor pole that a kind of anchoring slight slope is used, particularly for weak soil
Building slope engineering support, 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
Meaning weak soil, refers to natural void ratio more than or equal to 1.0 and natural moisture content is more than the fine grained soil of liquid limit.It is this kind of soil point be
Internal friction angle and cohesive strength all very littles of the soil body, are easily deformed, liquefy, and to engineering support design and construction very big difficulty is brought,
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, is increased reliability, and is not increased substantially engineering and make
Valency is very urgent demand.What the anchor pole for being used at present, generally reinforcing bar or steel wire strand were constituted, by Grouting Pipe and anchor
Muscle is combined, in putting the hole being drilled into, 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 it is just very poor to the effect of weak soil.
The content of the invention
It is an object of the present invention to design a kind of anchor pole used in soft clay foundation, to increase frictional force, anchor pole is increased
Breakout capacity.Realize that the purpose of the present invention is adopted the technical scheme that：A kind of software rhizoma nelumbinis shape anchor pole, include dowel and
Grout pipe, it is characterised in that：The end of dowel is fixed with end fixed body, and geotechnological cloth bag loads dowel and grout pipe set,
The diameter of geotechnological cloth bag is gradually increased by head end to end, and the end of geotechnological cloth bag is with end larynx hoop banding in end fixed body
On, 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 by dowel
It is fixed with grout pipe, using head end larynx hoop banding on head end fixed body, geotechnological cloth bag is by head end for the head end of geotechnological cloth bag
Fastening straps are fixed on geotechnological cloth bag according to the ascending order of diameter to end direction, the spacing of fastening straps is according to calculating
Anchor force determines.
The present invention can significantly improve anchor force of the anchor pole in bury, because anchoring body regular shape so that reliable
Property is increased substantially.

Specific 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 on end fixed body 1, the grout outlet 9 of grout pipe 6 sets the end of geotechnological cloth bag 3 banding of end larynx hoop 2
In the end of geotechnological cloth bag 3, the head end of dowel 5 and grout pipe 6 is provided with head end fixed body 8 carries out dowel 5 and grout pipe 6 admittedly
Fixed, using the banding of head end larynx hoop 7 on head end fixed body 8, geotechnological cloth bag 3 is by head end to end direction for the head end of geotechnological cloth bag 3
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.
The structure design of the present invention is such：The sufficiently large geotextiles of use intensity make the geotechnological cloth bag 3 of cylindrical shape,
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 determines, geotextiles
Intensity is sufficiently large, permeable, but impermeable slurry.In the longitudinal direction, keep at a certain distance away setting fastening straps 4, the material of fastening straps 4 and
Geotextiles are identical, and thickening becomes band.Fastening straps 4 are processed circlewise, is pasted onto on geotechnological cloth bag 3 with seccotine, or by beam
Taut band 4 and geotechnological cloth bag 3 are sewed in one.The diameter of fastening straps 4 is gradually increased from head end to end, geotechnological cloth bag is fixed on
On.Dowel 5 is together with the colligation of Grouting Pipe 6.At the two ends of dowel 5, end fixed body 1 and head end fixed body 8 are set with fixation
Geotechnological cloth bag 3, end fixed body 1 and head end fixed body 8 it is cylindrical, centre is respectively provided with groove, is easy to make larynx hoop snap in wherein,
Fixed body diameter is put anchor hole into and is defined less than the diameter of geotechnological cloth bag to facilitate.By geotechnological cloth bag 3 end larynx hoop 2 and 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, by slip casting
Pipe slip casting, under the effect of slip casting pump pressure, enters into cloth bag from end grout outlet, and slurries progressively fill geotechnological cloth bag side by side
Water, due to pressure field bag full of when be to be close to uniform, so slurries will form the cylinder of almost symmetry, wrap anchor
Muscle.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, thus increase
Anchor force.Because foundation soil is weak soil, easily by compression, so this anchor pole is adapted to soft clay foundation.
When using, geotechnological cloth bag 3 is processed 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 in proper order on geotechnological cloth bag 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 end of close dowel 5 in geotechnological cloth bag 3.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, installs and is in the milk by grout pipe 6 behind block section, in the case where slip casting pump pressure is acted on, slurries from
Grout outlet 9 is entered into geotechnological cloth bag, starts to fill geotechnological cloth bag from end in the presence of grouting pressure, and extruding weak soil is side by side
Moisture removal, under the constraint of geotechnological cloth bag, gradually forms taper anchoring body.Then according to normal dowel construction method installs anchor
Head.
