Description
Technical field
The present invention relates to a kind of constructing tunnel servicing unit, more particularly, to a kind of tunnel of the simple automatic exhaust device of band
Hollow grouting anchor.
Background technology
During constructing tunnel, the bolt grouting quality of advance support and preliminary bracing directly influences anchor pole in tunnel
The effect for rock crusher is prevented during construction, caving in, hollow grouting anchor can fully be anchored in anchor pole total length, and can be stood after excavation
Certain supporting drag is provided, suppresses the loosening and deformation of country rock, it is to avoid or extenuate engineering construction and landslide during use emits
Useful event or the generation of other diseases, have enough and uniform protective layer thickness particularly around the body of rod, greatly strengthen anchor
The durability of bar, and using common hollow bolt when slip casting is carried out because slurries from head enter the body of rod when anchor pole end
Inside rock mass, air in the body of rod is caused to discharge, inner air increases by compression pressure, causes slurries to fill
The body of rod possibly even has the danger for pressing quick-fried Grouting Pipe so that anchor bolt construction cannot play due effect.
Prior art is that two sections of anchor poles are connected by coupling sleeve device, and cost is higher, waste of material is more and bar
Body is insecure.And the angle of in constructing at the scene squeezing into rock mass due to anchor pole is different, the application requirement of anchor pole has flexibility, together
Shi Yaoqiu can faster be machined with the change for squeezing into rock mass angle using general anchor pole material.
The content of the invention
Deficiency for existing product of the invention, and the hollow slip casting anchor in tunnel that a kind of simple automatic exhaust device of band is provided
Bar.
A kind of tunnel hollow grouting anchor of the simple automatic exhaust device of band of the invention, including hollow bolt, body of rod hole
Eye, grouting port, exhaust outlet, venting conduit inlet, the hollow bolt inside middle offer body of rod eyelet, and body of rod eyelet is passed through
Hollow bolt is worn, blast pipe is installed in body of rod eyelet；The front end of hollow bolt is provided with venting conduit inlet, the tail of hollow bolt
End is provided with exhaust outlet, and the end of the exhaust outlet of hollow bolt and grouting port are communicated.
Further, the front end of the hollow bolt is installed with and is provided with protection drill bit, and the protection drill bit internal sets
Cavity is equipped with, cavity and venting conduit inlet are connected.
The beneficial effects of the invention are as follows：1st, it is rational in infrastructure, it is easy to manufacture, low cost；2nd, it is practical, it is safe and reliable；
Simple to operate in site operation, material is general and does not produce waste, at the construction field (site) using solving hollow grouting anchor slip casting
Full practical problem.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
In figure：Hollow bolt 1, body of rod eyelet 2, grouting port 3, exhaust outlet 4, venting conduit inlet 5.
Specific embodiment
With reference to embodiment, the invention will be further described.
A kind of tunnel hollow grouting anchor of the simple automatic exhaust device of band of the invention is main by the hollow bolt 1, body of rod
Eyelet 2, grouting port 3, exhaust outlet 4, venting conduit inlet 5 are constituted.
A kind of tunnel hollow grouting anchor of the simple automatic exhaust device of band, including hollow bolt 1, body of rod eyelet 2, slip casting
Mouth 3, exhaust outlet 4, venting conduit inlet 5, the inside middle of the hollow bolt 1 offer body of rod eyelet 2, and body of rod eyelet 2 is passed through
Wear in hollow bolt 1, body of rod eyelet 2 and blast pipe is installed；The front end of hollow bolt 1 is provided with venting conduit inlet 5, hollow bolt
1 tail end is provided with exhaust outlet 4, and the end of the exhaust outlet 4 of hollow bolt 1 and grouting port 3 are communicated.
The front end of the hollow bolt 1 is installed with and is provided with protection drill bit, and the protection drill bit internal sets free
Chamber, cavity and venting conduit inlet 5 are connected.
When using, hollow grouting anchor 1 is processed by drawing and arrives appropriate length；
Body of rod eyelet 2 is processed in body of rod one end, a plastics blast pipe to anchor pole bottom blast pipe is inserted from the position of body of rod eyelet 2
Entrance 5, the exhaust outlet 4 that the other end is stayed in outside bar；
When slip casting is carried out, air in the body of rod is set to enter into blast pipe to slurries, pressure effect is injected in the body of rod by grouting port 3
Mouth 5, from outside the discharge bar of exhaust outlet 4；This process lasts up to fill slurries in anchor pole.
A kind of tunnel hollow grouting anchor of the simple automatic exhaust device of band of the invention, it is practical, it is safe and reliable；
Simple to operate in site operation, material is general and does not produce waste, at the construction field (site) using solving hollow grouting anchor slip casting
Full practical problem, detachable recycling, reduces construction cost.
Embodiments of the invention are the foregoing is only, the scope of the claims of the invention is not thereby limited, it is every to utilize this hair
Equivalent structure or equivalent flow conversion that bright description is made, or directly or indirectly it is used in other related technology necks
Domain, is included within the scope of the present invention.
