Description
Technical field
The present invention relates to a kind of anchor rod device for being used to fix adjoining rock stability, more particularly to a kind of segmentation of energy automatic clamping
Archoring slip casting archoring-balt device and its anchoring process.
Background technology
Anchor pole is to be anchored between coal or rock mass and the rod-like structure thing stable for safeguarding Surrounding Rock Masses of Roadway, suspension roof support
It is a kind of active support form, Bolted Rock Masses is produced compression area and play reinforced action to reinforcing rock stratum, greatly strengthen
The intensity of country rock, improves the overall mechanical properties of country rock rock stratum.Due to anchor pole have higher bearing capacity, and cost it is relatively low,
Into lane speed is fast, labor intensity is low and is obviously improved many merits such as operating environment and safety in production, coal mining enterprise is had become
A kind of main support pattern of shaft and drift supporting, represents the main development direction of roadway support form.But, according to live tunnel
Support conditions, and combine knowable to the force structure of anchor pole in itself, when anchor pole is that supporting is extremely crushed, with uneven casing lane
During road country rock, suspension roof support stress is just extremely uneven, the shearing force that is subject to of position or pulling force close to anchor pole free end compared with
Greatly, the rockbolt stress of the deep part of anchor pole is smaller, meanwhile, it is deeper to add rock crusher scope, using common bolt due to it
Anchorage length is not enough difficult to anchor to the stable rock stratum in deep, which results in bearing capacity during single branch suspension roof support is extremely limited, often
Occur that anchor pole is integrally drawn out, pallet is slipped, or even middle part occur the failure phenomenon such as being pulled off, in turn result in wall rock destabilization
Destruction, has had a strong impact on the normal safety in production of mine.In order to improve such supporting roadway surrounding rock problem, confined pressure entirety is improved
Bearing capacity, often increases bolt diameter, increase rock-bolt length or segmentation anchoring and reduces the modes such as the distribution spacing of anchoring
Improve the stressing conditions of anchor pole, but so not only increase overall support cost, and support issues also do not obtain root
Solution in sheet.
