Description
Technical field
The present invention relates to building foundation pit and slope retaining technical field, especially a kind of tensioning umbrella anchored end.
Background technology
In subway open-cut foundation ditch, highway and Along Railway slope protection works and China Democratic National Construction Association's foundation ditch, it is often necessary to which free face is carried on the back
The unstable soil body carries out supporting afterwards, to prevent foundation ditch and slope deforming, unstability, landslide.Anchoring support system is foundation ditch and side
One of new technique not only economic but also practical, is made up of Retaining Structures and anchor cable system two parts in the engineering of slope.Anchoring support
System utilizes anchor cable（Bar）The soil pressure that soil-baffling structure at free face is born in the form of pulling force to be delivered in the stable soil body in deep
Anchoring section, then the pulling force is delivered to by the stable soil body in anchor hole periphery by the interaction between anchoring section and the stable soil body.
Anchor cable（Bar）Pattern is various, divides main according to the mode of action between anchoring section pattern and anchoring section and the stable soil body
Including three kinds of cylindrical type, continuous ball-shape and anchored end expansion type.Wherein anchored end expansion type anchor cable（Bar）Anchoring section with it is steady
Determine adhesion strength of the effect between soil layer between anchoring body and the soil body and expand the end of soil layer at body to hold intensity two parts and constitute, because
The anchor cable of this type（Bar）Higher withdrawal resistance can be provided, the quality of anchoring support system is significantly improved, with preferable
Economic benefit.
The research to anchored end expansion type anchor pole is goed deep into constantly both at home and abroad, and blasting procedure and water jet method are occurred in that in succession
For the non-mechanical reaming method that represents and pressure formula mechanical hole reaming method and mechanical reaming method that PCBA reamings earth anchor is representative.
Above reaming engineering method is noteworthy characterized by：Reaming forms later anchoring section slurries and bonds the anchored end to form expansion with dowel, carries
For anchor force.But these methods need to apply special broaching equipment or material, equipment price and operating expenses are expensive, construction technology
Complexity, large volume reaming is very difficult, and the raising of anchor force is limited.Therefore need badly and study new anchored end expansion type anchor pole,
Ensure that anchoring support system can provide larger withdrawal resistance, while should also take into account the convenience and operability of construction.
The content of the invention
The purpose of the present invention is there is provided a kind of tensioning umbrella anchored end, in drilling according to above-mentioned the deficiencies in the prior art
When can with drilling rod to soil layer deep move, in place after can be by pulling anchor cable the anchor plate in anchored end is expanded to periphery
The stable soil body in inlay bur hole depth portion is opened, so as to improve the withdrawal resistance and stability of support system.
The object of the invention is realized and completed by following technical scheme：
A kind of anchoring system based on tensioning umbrella anchored end, for carrying out supporting to soil-slope, it is characterised in that：The anchor

Before, anchor cable 15 is tensed, the stress destruction of pad 3 between guide plate 4 and anchor plate 6, the removable upward sliding of ring flange 10 draws
Pin joint of the anchor plate 6 at fixing pin 9 is played progressively to rotate and along the outer rim of guide plate 4 to peripheral expansion inlay bur hole depth
The stable soil body in portion, so as to improve the withdrawal resistance and stability of support system.The expansion action of anchor plate 6 is until removable ring flange
10 stop when being moved to limiting plate 7.
4）Drilling rod is disengaged with tensioning umbrella anchored end 16 by back-drilling, and extracts drilling rod.
5）To the slip casting of anchoring section 21, middle grout cures hole to be drilled are reached after design strength, at anchor cable 15 and anchor head 13
Tensioning equipment is connected, and applies pretightning force, after pretightning force reaches design load, and the He of waist rail 22 is installed in the outside of soil-baffling structure 19
Cushion block 14, then anchor head 13 is locked into anchor cable 15 form reliable and stable anchoring system.
6）1 is repeated to each anchor cable system in anchoring system）-5）The step of complete the construction of whole anchoring system.
The present embodiment is in the specific implementation：Anchor cable 15 can be steel wire, the steel for connecting anchor head 13 and removable ring flange 10
Twisted wire or glass fiber-reinforced polymer.
In order to ensure being smoothed out for drilling, it is to avoid anchor plate 6 has been inserted into the periphery soil body, anchor plate 6 in drilling process
Initial expanded diameter should be less than aerofoil profile creep into piece 12 expanded diameter.
The quantity of anchor plate 6 is chosen as 4-8 pieces, but its distribution should be in equally center centered on the center of circle of thin-wall circular tube 8
It is arranged symmetrically；Similarly, the quantity of anchor cable 15 is 2-4 beams, and anchor cable hole 5 and anchor cable hole 11 for connecting anchor cable 15 also should be with thin-walleds
It is centrosymmetric and is opened on guide plate 4 and removable ring flange 10 centered on the center of circle of pipe 8.
Although above example is elaborated referring to the drawings the design to the object of the invention and embodiment, this
Field those of ordinary skill will recognize, limited without departing from claim under the precondition of scope, still can be right
The present invention makes various modifications and variations, therefore does not repeat one by one herein.
