Description
Technical field
The present invention relates to mooring rod technique field, more particularly to a kind of anti-rock burst and large deformation wing formula splitting type energy-absorption anchor rod and
Structure.
Background technology
Bolt support technology has the history of more than 100 years so far, have become the ground surface works such as geotechnical slope, foundation ditch and
One of wide variety of support pattern of the underground engineerings such as tunnel, stope, especially in underground engineering wall rock stability control more
Significantly.Conventional anchor pole is used for underground shallow part, can be divided into mechanical rock bolt, sticking failure and friction according to its force way difference
Formula anchor pole.Mechanical rock bolt i.e. expansion sleeve bolt, sticking failure rigidity is big, intensity is high, but ductility is small, deformability
Difference；Frictional rock bolt, pipe seam formula, the deformability of hydraulic expansion type anchor stock are big, but bearing capacity is low.
China greatly develops the field such as infrastructure construction, water conservancy and hydropower, traffic, civil engineering, the energy, nuke rubbish storage at present
Intensive expansion is built, the trend of Deep-buried Long And Big is presented in related underground engineering.Deep high stress, High-geotemperature, hyperosmosis and strong
The factors such as disturbance drastically influence the stability of underground engineering wall rock, and various engineering project disasters are increasing, are embodied in soft rock
Large deformation, hard rock rock burst etc., huge difficulty is brought to deep Underground Engineering Excavation and supporting.Traditional suspension roof support is in depth
Serious challenge is faced with portion's underground engineering, common sticking failure is in the case of rock mass large deformation often because itself becomes
Shape amount is insufficient and causes anchor pole failure damage, and frictional rock bolt once reaches Breaking load and will result in body of rod fracture and lose branch
Shield is acted on, and intensity decreases and deep rock is not adapted to the features such as be unable to shock resistance after common bolt elongation percentage deficiency, extension
The deformation-failure character of body.But in practical engineering application, many conventional anchors are still widely used in the underground engineering of deep, no
But support cost is improved, and has buried huge potential safety hazard.
Therefore, underground engineering wall rock suspension roof support in deep not only has high bearing capacity, more to have moderate finite deformation ability
Energy caused by transfer and absorption surrouding rock deformation, referred to as energy-absorption anchor rod or pressure-relieving achor bar, surrender anchor pole etc..Energy-absorption anchor rod presses it
Energy-absorbing principle can be divided into anchor head energy absorbing type and body of rod energy absorbing type two types, and anchor head energy absorbing type anchor pole is in grouted part or outer anchor
The energy absorption device (spring washer after sliding sleeve, backing plate on the body of rod etc.) of sustainable deformation, body of rod energy-absorbing are additionally arranged at head
Type anchor pole is then to realize energy-absorbing using body of rod elongation, and rod body material has high intensity, the feature of large deformation ability, or the body of rod
It is designed as F-SP (such as corrugated).
What domestic various types of energy-absorption anchor rods also emerged in an endless stream emerges in large numbers, but existing anchor pole still has many defects：
Such as patent publication No. CN201981537U " water expansion type elastic anchor rod for resisting rock burst ", publication number CN204691804U, " one kind is applicable deep
The anti-impact energy-absorption anchor rod pallet of portion's underground engineering ", publication number CN205743946U " a kind of erosion control energy-absorption anchor rod pallet " etc., mainly
Be by increasing energy-absorbing by pressure device (spring washer, deformation cylinder etc.) in outer anchored end, it is simple in construction, cost is cheap, installation side
Just, energy-absorbing and stress spread effect are preferable；But its overall deformation energy-absorbing makes pressure limited in one's ability, and exposed face of energy absorption device is occupied
Section headroom, need antirust, anti-corrosive, influence the problems such as construction.A kind of publication number CN101929347A " applicable high stress large deformation rocks
Body mining compatible deformation energy-absorption anchor rod ", publication number CN201857612U " one kind prolongs-elastic reactance rock burst anchor pole ", publication number
CN106640161A " a kind of high intensity energy-absorption anchor rod with good elongation " etc., a body of rod free segment part is designed as wave
Shape is deformed to absorb energy, simple structure, making and easy for construction；But the body of rod is often directly and air contact, its anti-corrosion
And poor durability.Publication number CN102286975A " a kind of constant-resistance energy-absorption anchor rod for reinforcing large deformation rock mass ", publication number
CN104265339A " one kind extruding, friction type energy absorbing bolt ", publication number CN101858225A " constant resistance and large deformation anchor rod " etc., it is main
To reach energy-absorbing by allowing pressure device (sleeve pipe) deformation or sliding etc. to realize the compatible deformation of anchor pole and country rock on the body of rod and allow
The purpose of pressure；But making is complicated, difficulty of construction is big, cost is high, is unfavorable for the popularization and application in Practical Project.It is in addition, big at present
Part energy-absorption anchor rod is 2 anchor structures, i.e. grouted part and outer anchoring segment unit, once an element failure will cause it is whole
Individual anchor pole destroys.
