Description
Technical field
The present invention relates to technical field of civil engineering, the in particular to control of soft soil foundation pit slope deforming and deep pit support nurse
The umbrella-type that can be recycled used in journey anchors piled anchor of putting more energy into.
Background technique
Currently, in the side slope and Deep Foundation Pit Supporting Project on rock and pan soil stratum, prestress anchorage cable anchor with higher
Gu power, anchored pile supporting is widely applied.But the anchoring of soft soil layer is still the bottleneck of anchorage technology.Soft soil layer
Frictional resistance is low, and the deformation such as rheology is also easy to produce after stress, limits the application of anchorage technology.In addition, in civil engineering frequently with
Steel strand wires often stay after side slope and foundation pit enclosure structure complete mission as prestressing force dowel and form barrier in underground,
Which also limits the popularizations and application of this kind of support form.Therefore, higher anchor force can be generated in soft soil layer, control it
The deflection of weak soil, and after the completion of supporting construction mission, dowel can be recycled from the soil body, be that there is an urgent need to solve for engineering circles
Problem certainly.
In soft clay area, since water level is generally higher, the water content of weak soil is big.Meanwhile traditional anchoring body diameter only has
100~150mm, smaller with the bond area of weak soil, the frictional resistance of weak soil is lower in addition, and obtained anchor force is lower.In addition, soft
Soil has rheological property, and when the prestressing force of application is higher, the Rheological Deformation characteristic on stratum will be highlighted, and deformation is difficult to control
System.
In soft soil layer anchoring support, to the anchoring body of removable anchorage (patent No. ZL2015203006781) formation
Intensity is relatively low, when applying more high-prestressed, frequently results in anchoring bulk damage.If applying smaller prestressing force, the control effect of deformation
Fruit is often poor.Therefore, also there is an urgent need to research and develop anchor pole (rope) technology with higher anchor force to meet wanting for soft oil support
It asks.
In order to solve how to obtain biggish anchor force, effectively control deformation, the recycling of raising anchor cable in soft soil layer
Rate and guarantee anchoring security problems, there is an urgent need to develop a kind of novel pre-stressed umbrella-type anchoring piece.
Summary of the invention
Present invention solves the technical problem that be, overcome that the anchor force of existing Recyclable anchor rope is small, Support Deformation is big and returns
The disadvantages such as yield is low, provide a kind of umbrella-type anchoring piece of Recyclable anchor rope for pattern foundation pit supporting structure, umbrella-type skeleton end bearing
It is squeezed with borehole wall and generates anchor force, umbrella-type skeleton is also extruded with soil body borehole wall, generates anchor force.Slurries and umbrella-type
Skeleton sufficiently combines, and further improves anchor force.After support action completion, dowel can be recycled out from anchoring body
Come, be detached from anchoring body and dowel, realize the recycling of dowel, achievees the purpose that reduce project cost.Meanwhile removing stays in
Barrier in stratum.
To solve the above-mentioned problems, the technical scheme is that it is such:
A kind of dowel recoverable umbrella-type anchoring piece, anchoring piece include screw lock formula anchorage, low bottom-disc, support rod, the umbrella wing, on
Chassis, upper sleeve, tension flexible net help expansion to justify, lower sleeve portion, dowel；In anchoring body setting by top bottom-disc, support rod,
Umbrella-type skeleton composed by the umbrella wing, low bottom-disc, tension flexible net are connected to umbrella-type skeleton and help between expansion circle；Low bottom-disc front end is set
Screw lock formula anchorage is set, dowel passes through top bottom-disc, upper sleeve, lower sleeve portion, low bottom-disc and is connected with screw lock formula anchorage, each spiral shell
Locking-type anchorage locks a dowel；Screw lock formula anchorage is the position by control lock muscle clamping plate in taper anchor tube, to adjust lock
The degree of engagement of muscle clamping plate and dowel is realized and locks or unlock to dowel.
The dowel is provided with casing.
The umbrella-type skeleton that umbrella-type anchoring piece is formed, after applying external force, umbrella-type skeleton is strutted, and the soil body generates certain resistance to it
Power, when top bottom-disc is close to expansion bowlder is helped, the umbrella wing struts maximum value, to improve larger anchor force.
Tension flexible net can be strutted and be trailed with the umbrella wing, expand the interaction area of anchor head and the soil body, and with
The umbrella wing generates biggish withdrawal resistance together.
The working mechanism of this umbrella-type anchoring piece is similar to common umbrella, packs up it is characterized in that being put into its umbrella wing in injected hole,
It takes up space small；When work, anchor head voluntarily opens, and the space occupied is big, comes into full contact with the soil body, and anchor cable can reuse.
The utility model has the advantages that a kind of dowel recoverable umbrella-type for controlling side slope and foundation pit deformation of the present invention anchors
Part, the locking and unlock recycling and reusing of dowel are realized by screw lock formula anchorage, and artificial i.e. recyclable dowel improves dowel
Recovery efficiency and reuse ratio；By setting umbrella-type anchoring piece (umbrella chord is short to be adjusted according to soil layer), anchor force is increased, from
And solve the problems, such as that anchor force is small in recycling anchor pole (rope) technology.
