Description
Technical field
The utility model is related to building field, more particularly to a kind of churning reaming type sub warhead recoverable anchor rod stake.
Background technology
Recently as the maturation of bolt anchorage technology, range of application is increasingly in foundation ditch construction, slope protection works for anchor pole
Extensively, the extensive application of anchor pole has played important function for the national economic development, but with the further development of engineering construction, it is many
The once pre-buried place for crossing anchor pole will face secondary development.Those anchor poles for once playing important function but turn into be developed again
Obstacle, cause the increase of the difficult and construction cost of exploitation.Then the construction technology of recoverable anchor rod is generated, it is this to return
Half davit has both saved cost its essence is the material of the steel strand rope of anchor pole is extracted into recovery completely, avoids stretching into periphery again
Steel wire rope causes the obstacle of others' land development.
Current recoverable anchor rod form probably has three classes：（1）Combined type；（2）Expansion shell type；（3）It is spiral etc..Its skill
Art main points are：Former anchor pole is divided into two parts (body of rod section and anchoring section), an attaching nut, attaching nut are added between the two sections
Welded with body of rod section, be threadedly coupled with anchoring section.The body of rod section other end welds a nut, is easy to be enclosed within the nut using specialized barrel
Upper bridle catcher body section.Recoverable anchor rod is compared with original technology, solves the body of rod expendable problem of section, not only can be with barre
Body section is reclaimed, and need to only re-work anchoring section, and the body of rod section for reclaiming is reconfigured, and is reused, and can save fee of material,
Reduces cost.
（1）Combined type recoverable anchor rod（Part resin anchoring）
Combined anchor original be to be constructed in short tunnel designed by anchor pole long, can be in short lane by this structure
Injection rock-bolt length is more than the anchor pole of head-room in road, and the combined anchor can also be used instead of short anchor cable, constructs
Process is simple, construction reliability is high, recyclable simple and reliable process.If the anchor pole substitutes anchor cable and uses, construction is simple, economical
There is good feasibility in upper and technique.
（2）Expansion shell type recoverable anchor rod（Mechanical anchor）
Expansion type rock bolt（Mechanical anchor）As recoverable anchor rod, from technique with feasibility, but practical application
It is higher to construction process requirement.
（3）Spiral recyclable anchor rod（Friction anchoring）
Spiral anchoring-bolt is designed as recoverable anchor rod, but in actual application, mainly as breaking surrounding rock lane
Road anchors to use, and is not used as recoverable anchor rod.If deformation of the surrounding rock in tunnel is larger, the anchor pole can be with deformation, this
When anchor recovering difficulty it is big, the rate of recovery is low.
Be present shortcomings in anchor pole form and other current anchor pole forms described above, be summarized as follows：
Fixing end cost is expensive；
, used as the new product for just producing in recent years, technology is extremely immature, less stable for fixing end, and the body of rod rate of recovery is relatively low,
Often do not reach 50%.
How recuperable anchor pole is developed, it is desirable to which the anchor pole not only has on the premise of with bearing capacity higher
There is good recovery performance, and recovery process is simply easily operated.For this, I develops a kind of new recoverable anchor pole patent
Technology.
