Flexible attached branch is set on the section formula body of rod, and upper and lower ends are provided with spiral interface, and multiple segment type bodies of rod can pass through upper and lower two
The spiral interface at end is connected with each other；Spiral interface is provided on fixed core, it can be with the spiral interface of segment type body of rod lower end
Connection.
Further, it is provided with spring between the attached branch of elasticity and the segment type body of rod.
Further, the angle between the attached branch of elasticity and the segment type body of rod is 10-80 °.
Further, pallet is installed on fixed core.
Further, it is also equipped with nut on fixed core.
Further, the 2-4 attached branch of elasticity is provided on the segment type body of rod.
Further, the attached branch recoverable anchor rod of segment type elasticity further includes anchor point, and anchor point lower end is provided with spiral interface, can
It is connect with the spiral interface with segment type body of rod upper end or fixed core upper end.
The advantageous effect brought of technical solution that the utility model embodiment provides is：The segment type elasticity of the utility model
Attached branch recoverable anchor rod can increase or decrease the number of the segment type body of rod at any time according to field condition, adjust rock-bolt length, into
And efficiently using anchor pole, it is more cost-effective that strong situation is changed to construction site soil thickness；By the attached branch of elasticity and
Spring section increases resistance, can be with rapid construction without grouting, and the process that reduces construction does not need to consolidation time, reduction is applied
The work period；Fixed core detachably reuses, and reduces production cost, and then greatly save metal steel, reduction is produced into
This, increases income.

Specific embodiment
It is new to this practicality below in conjunction with attached drawing to make the purpose of this utility model, technical solution and advantage clearer
Type embodiment is described in further detail.
Embodiment
As shown in Figs. 1-3, the attached branch recoverable anchor rod of segment type elasticity of the utility model includes fixed core 1 and segment type
2 two parts of the body of rod.
2 upper end of the segment type body of rod is provided with upper end spiral interface 3, and lower end is provided with lower end spiral interface 4.In the present embodiment
In, multiple segment type bodies of rod 2 are provided with, each segment type body of rod 2 is mutual by upper end spiral interface 3 and lower end spiral interface 4
It connects, it can be according to situations such as actual demand, the variation of ground body thickness, by the number for increasing and decreasing the segment type body of rod 2 in work
It measures to change rock-bolt length.2-4 elasticity attached branch 5 is installed, the attached branch 5 of elasticity and the segment type body of rod 2 are certainly on the segment type body of rod 2
Under conditions of so, angulation is 10 ° to 80 °.Spring 6 is additionally provided between the attached branch 5 of elasticity and the segment type body of rod 2, it can
Play the role of the preferably connection segment type body of rod 2 and the attached branch 5 of elasticity.
Spiral interface 7 is provided on fixed core 1, it can be tight by spiral with the lower end spiral interface 4 of the segment type body of rod 2
Tight to twist jail, pallet 8 is sleeved among spiral interface 7, and nut 9 is mounted at the screw thread of spiral interface 7.For by spiral interface 7,
1 part of fixed core that pallet 8 and nut 9 form, can rotate and disassemble, be recycled, and then greatly reduce
The cost of production.
Anchor point 10 is further included in the present embodiment, and 10 lower ends of anchor point are provided with spiral interface (being not drawn into figure), Ke Yiyu
The upper end spiral interface 3 of the segment type body of rod 2 connects.
During the anchor pole is used, as shown in figure 4, along the direction of the attached branch 5 of elasticity, by the merogenesis of the utility model
Among the attached branch recoverable anchor rod implantation soil body of formula elasticity, during the body of rod is gradually implanted into the soil body, the top meeting of the attached branch 5 of elasticity
Because receiving the squeezing action of the soil body, and tightly touch on the segment type body of rod 2.
As shown in figure 5, after the body of rod has fully entered the soil body, the body of rod is acted on down by external force, and the attached branch 5 of elasticity is opened,
Tightly melt together with the soil body of surrounding, the respective action of spring 6 can also securely fix it.At this point, the segment type body of rod 2, bullet
Property attached branch 5 and spring 6 also have around the soil body will be anchored together, play good anchorage effect, prevent well
The downslide of foundation pit, protuberance and the side slope downslide of the substrate soil body and mine cave in.
The utility model can increase or decrease the number of the segment type body of rod 2 at any time according to field condition, and it is long to adjust anchor pole
Efficiently using anchor pole, it is more cost-effective to change strong situation to construction site soil thickness for degree.1 part of fixed core
Detachable recycling, recycling, and then metal steel are greatly saved, production cost is reduced, increases income.The anchor pole is without filling
Slurry, can be with rapid construction；Unlike being in the milk, formula anchor pole needs certain time to consolidate, and reduces construction period；And the effect anchored can
To display as quick as thought.
Above-mentioned the utility model embodiment serial number is for illustration only, does not represent the quality of embodiment.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
