Description
Technical field
This utility model patent is related to tunnels and underground engineering surrounding rock supporting, and more particularly to one kind is applied to tunnel and underground
The a kind of rotary of engineering surrounding rock supporting can quick anchoring installation binding type hollow bolt.
Background technology
Anchor pole is a kind of tension member structure that structure anchor or Rock And Soil are reinforced, and is divided into prestressed anchor and non-prestressed
Anchor pole.Prestressed anchor is a kind of active support pattern, and stretching force can be delivered in stable or suitable Rock And Soil, so as to
By structure is together with anchoring in rock and soil or reinforces Rock And Soil.Non-prestressed anchor pole is a kind of passive protecting pattern, by with rock
Soil body common eigenvector, so as to play a part of to reinforce Rock And Soil.Suspension roof support is widely used to tunnels and underground engineering, side
The engineerings such as slope, foundation ditch.Suspension roof support is the important component part of bolt-spary supports, improves the support efficiency of country rock, is optimized each
The carrying ratio of supporting is planted, engineering construction safety has been ensured, has been saved construction costs.
Total length binding type anchor pole is widely used in tunnels and underground engineering.Total length binding type anchor pole is that the body of rod is exhausted in bolthole
Largely or entirely wrapped up by Anchor Agent, the Main Function of Anchor Agent has at 2 points, the first plays cementation, by anchor rod body with
Rock And Soil is cemented together；Which two has been protective action, and anchor rod body total length parcel can be protected to anchor pole anti-corrosion.According to
The difference of Anchor Agent, total length binding type anchor pole are divided into resin anchor and anchor rod with cement mortar, and anchor rod body has the steel body of rod (real
The heart, hollow and anchor cable) and fiber reinforced plastics pole body (solid and hollow).
Resin anchor is mainly used in coal roadway support.Resin (volume) Anchor Agent is separated with firming agent two parts by resin-bonded mastic
Packaging scroll, after mixing anchor rod body can be bonded together with Rock And Soil.Supper-fast type resin anchoring agent has two types,
That is CKa types and CKb types.After resin-bonded mastic and firming agent mixing, the gel time of CKa type resin anchoring agents is 8～25 seconds, anchor pole
The set-up time is waited to be 10～30 seconds；The gel time of CKb type resin anchoring agents be 26～40 seconds, anchor pole wait the set-up time be
30～60 seconds.Coal entry anchor rod support, resin anchor typically completed the installation of backing plate and nut in 60 seconds, and can apply one
Fixed pretightning force.At present, resin anchor is the leading pattern of coal entry anchor rod support, mainly by following several respects factor：(1) coal
And ature of coal formation rock hardness is less, pneumatic roof bolter drilling is easier；(2) resin anchor aperture ratio (anchor hole internal diameter with
The ratio of anchor rod body external diameter) it is less, rock-bolt length is generally 1.6m～2.6m, and resin explosive roll usage amount is few, has cost excellent
Gesture；(3) the inherently good solid lubrication material of ature of coal breeze, has ensured that resin explosive roll and anchor rod body are smoothly inserted into little
The anchor hole of aperture ratio；(4) after in resin anchoring agent, resin-bonded mastic is mixed with firming agent, setting time is shorter, is adapted to Fast Installation work
Skill；(5) resin gel gel strength is higher, and resin anchor withdrawal resistance is higher.
Although resin anchor is the leading pattern of coal entry anchor rod support at present, in highway/railway tunnel, hydraulic tunnel
And using less in underground chamber, especially railway tunnel, main cause are as follows：(1) Railway Tunnel Surrounding Rock complex geologic conditions
It is changeable, it is difficult to form the anchor hole of small-bore ratio in weak, broken formation；(2) the general long 2.5m of railway tunnel system anchor bolt～
5.0m, resin explosive roll and anchor pole may not be smoothly inserted in the anchor hole of small-bore ratio；(3) anchor hole of large aperture ratio needs more
Many resin anchoring agents, resin anchor are relatively costly.
Anchor rod with cement mortar (body of rod is solid and hollow) is highway/railway tunnel and hydraulic tunnel and underground chamber anchor pole
The leading pattern of shield.The strength of cement mortar grade of railway tunnel rule gauged mortar anchor pole is not lower than M20.Total length binding type anchor
The backing plate of bar and nut are installed and should be carried out after the intensity of cement mortar reaches 10MPa, therefore, the final set of cement mortar slurry and
The growth of early strength generally determines that suspension roof support applies the cost time.M20 strengths of cement mortar reach 10Mpa, estimate
1～2 day is taken, that is, anchor nut is finally tightened and needs wait 1～2 day, therefore, solve Tunnel Engineering shortening system anchor bolt and apply
Make the time, improve anchor bolt construction quality, the key for optimizing constructing tunnel operation is that anchor pole quick anchoring is installed.
Utility model content
