Description
Technical field
This utility model patent relates to tunnels and underground engineering surrounding rock supporting, is applied to tunnel and underground particularly to one
A kind of push-press type of engineering surrounding rock supporting can install binding type hollow bolt by quick anchoring.
Background technology
Anchor pole is a kind of tension member architecture 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, can be delivered in stable or suitable Rock And Soil by stretching force, thus
Structure or is reinforced Rock And Soil together with anchoring in rock and soil.Non-prestressed anchor pole is a kind of passive protecting pattern, by with rock
Soil body common eigenvector, thus play the effect reinforcing Rock And Soil.Suspension roof support is widely used to tunnels and underground engineering, limit
The engineering such as slope, foundation ditch.Suspension roof support is the important component part of bolt-spary supports, improves the support efficiency of country rock, optimizes each
Plant the carrying ratio of supporting, ensured engineering construction safety, 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 being wrapped up by Anchor Agent, the Main Function of Anchor Agent has 2 points, and the first plays cementation, by anchor rod body with
Rock And Soil is cemented together；It two has been protective action, can be protected anchor pole anticorrosion by anchor rod body total length parcel.According to
The difference of Anchor Agent, total length binding type anchor pole is 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
It is packaged into scroll, anchor rod body after mixing, can be made to be bonded together with Rock And Soil.Supper-fast type resin anchoring agent has two types,
I.e. CKa type and CKb type.After resin-bonded mastic and firming agent mixing, the gel time of CKa type resin anchoring agent is 8～25 seconds, anchor pole
Wait that the set-up time is 10～30 seconds；The gel time of CKb type resin anchoring agent is 26～40 seconds, and anchor pole waits that the set-up time is
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 boring is easier；(2) resin anchor aperture ratio (anchor hole internal diameter with
The ratio of anchor rod body external diameter) less, rock-bolt length is generally 1.6m～2.6m, and resin explosive roll usage amount is few, has cost excellent
Gesture；(3) ature of coal breeze inherently good solid lubrication material, 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 mixes with firming agent, setting time is shorter, is suitable for 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, but at highway/railway tunnel, hydraulic tunnel
And underground chamber is applied less, especially railway tunnel, main cause is as follows: (1) Railway Tunnel Surrounding Rock complex geologic conditions
Changeable, weakness, broken formation are difficult to be formed the anchor hole of small-bore ratio；(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 is relatively costly.
Anchor rod with cement mortar (body of rod solid and hollow) is highway/railway tunnel and hydraulic tunnel and underground chamber anchor pole props up
The leading pattern protected.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 determines suspension roof support generally and applies the cost time.M20 strength of cement mortar reaches 10Mpa, estimates
Taking 1～2 day, namely anchor nut is finally tightened needs to wait 1～2 day, therefore, solves Tunnel Engineering shortening system anchor bolt and executes
Make the time, improve anchor bolt construction quality, optimize constructing tunnel operation it is crucial that anchor pole quick anchoring is installed.
Utility model content
This utility model patent technical problem to be solved is to provide a kind of push-press type can install binding type by quick anchoring
Hollow bolt, to realize country rock quickly or passive protecting, improves anchor bolt construction efficiency and construction quality, effectively controls supporting
Engineering cost.
It is as follows that this utility model patent solves the technical scheme that its technical problem used:
Push-press type of the present utility model can install binding type hollow bolt, including the hollow bolt body of rod and connection by quick anchoring
In the anchor head being made up of backing plate, nut of its rear end, it is characterized in that: the front end of the described hollow bolt body of rod is provided with pressure and pushes away spiral shell
Bar, converter assembly, packed Anchor Agent is arranged on pressure and pushes away on screw rod；Described pressure pushes away screw rod and has non-self-lock-ing external screw thread, with conversion
Device matches formation leading screw and nut mechanism；The front end of described transducer is the fluted disc with some cone teeth.
This utility model patent provides the benefit that, packed Anchor Agent is arranged on pressure and pushes away on screw rod, it is simple to packed Anchor Agent
Sending to top in anchor hole, firmly push the tail end of the hollow bolt body of rod, pressure pushes away screw rod and progresses into the mesopore of the hollow bolt body of rod
In, packed Anchor Agent is formed extruding, drives transducer to rotate simultaneously, the fluted disc of its front end blend the outsourcing of packed Anchor Agent
Dress, makes Anchor Agent serosity mix, thus anchoring section quick anchoring before anchor pole, after the anchor pole less than 60 seconds waits the set-up time
Backing plate and nut can be installed, and certain prestressing force can be applied in advance, subsequently by hollow bolt body of rod slip casting, it is achieved anchor pole
Rear anchoring section total length bonds, and quickly completes whole anchor rod anchored installation, it is achieved country rock quickly or passive protecting, improves anchor
Bar efficiency of construction and construction quality；Stratum can be suitable for wide as lower-prestressed anchor pole and the system anchor bolt of non-prestressed anchor pole, can
It is greatly shortened system anchor bolt and applies the time, improve anchor bolt construction quality, give full play to intensity and the self-bearing ability of country rock, for tunnel
And underground engineering construction provides safety guarantee, also can optimized construction procedure；Before anchor pole, anchoring section is anchored by Anchor Agent, rear anchoring section
Employing slip casting anchors, and can effectively control support engineering cost.
