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
To be connect with the spiral interface of segment type body of rod upper end or fixed core upper end.
The advantageous effect that technical solution provided in an embodiment of the present invention is brought is:The attached branch of segment type elasticity of the present invention can return
Half davit can increase or decrease the number of the segment type body of rod at any time according to field condition, adjust rock-bolt length, and then efficiently
Using anchor pole, it is more cost-effective that strong situation is changed to construction site soil thickness;Pass through the attached branch of elasticity and spring section
Increase resistance, can be with rapid construction without grouting, the process for reducing construction does not need consolidation time, reduces construction period;
Fixed core detachably reuses, and reduces production cost, and then greatly save metal steel, reduces production cost, increases
Income.

Specific implementation mode
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention
Formula is described in further detail.
Embodiment
As shown in Figs. 1-3, the attached branch recoverable anchor rod of segment type of the invention elasticity includes fixed core 1 and the segment type body of rod
2 two parts.
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
Connection, passes through the number for increasing and decreasing the segment type body of rod 2 at can be according to actual demand, the variation of ground body thickness in work situations such as
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 °.It is additionally provided with spring 6 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 elastic attached branch 5.
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.
Further include anchor point 10 in the present embodiment, 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 using the anchor pole, as shown in figure 4, along the direction of elastic attached branch 5, by the segment type bullet of the present invention
Property the attached branch recoverable anchor rod implantation soil body among, during the body of rod is gradually implanted into the soil body, the top of the attached branch of elasticity 5 can because
The squeezing action of the soil body is received, and is tightly touched 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 by under outer force effect, open by the attached branch 5 of elasticity,
Tightly melt together with the soil body of surrounding, the respective action of spring 6 can also be such that it securely fixes.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 present invention can increase or decrease the number of the segment type body of rod 2 at any time according to field condition, adjust rock-bolt length, high
Effect ground utilizes anchor pole, and it is more cost-effective to change strong situation to construction site soil thickness.1 part of fixed core is detachable
Recycling, recycling, and then metal steel are greatly saved, production cost is reduced, income is increased.The anchor pole, can without grouting
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 be exceedingly fast
Ground displays.
The embodiments of the present invention are for illustration only, can not represent the quality of embodiment.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
