Description
Technical field
The utility model belongs to Geotechnical Engineering field, and in particular to a kind of external poured is segmented anchoring rod.
Background technology
The energy is as the indispensable material base of survival and development of mankind, especially coal in China's primary energy is constituted
Occupy an leading position.As China is to Coal Resource Development, current superficial part resource has been gradually decreased and exhausted, exploitation of coal resources
Constantly develop to deep, mine resource is exploited from the superficial to the deep, causes tunnel, the stress of chamber surrounding rock body to significantly increase,
And the situation of soft-rock slope may also occurs in the experience high-ground stress effect of superficial part country rock.Surrouding rock deformation is notable, broken serious,
This just buries many hidden danger for the safety problem of shaft production, therefore needs safer supporting facility.Colliery tunnel support is passed through
Go through wooden support, build warm and sunny supporting, the lengthy procedure of shaped steel supporting to suspension roof support.At present, bolt support technology is at home and abroad
It is widely used, is that colliery realizes that high-yield and high-efficiency produces one of essential key technology.Since 21 century, China
Coal mine roadway suspension roof support complete set technology, including anchor rod supporting theory, roadway surrounding rock geological mechanics test, anchor pole branch are formed
Protect design, support material, construction equipment and technique, support engineering quality testing, ore pressure monitor and special geologic condition supporting skill
All many-sides such as art.New anchor rod supporting theory is proposed, traditional anchor rod supporting theory has suspention, combination beam, reinforces the reason such as arch
By, played a positive role in production practices, but with certain limitation, in underground, actual measurement, numerical computations etc. are studied into
On the basis of fruit, for complicated complicated roadway condition, high pre-stress, strength support theory are proposed.The improvement of suspension roof support material,
The new support material suitable for high-ground stress tunnel has been developed, anchor rod strength has been increased substantially, develops Special anchor rod
Steel are formulated.High molecular material resin Anchor Agent is researched and developed, its intensity is big, and quick solidifying, security reliability is high, is widely used to coal
Lane suspension roof support.The utility model solves needs from engineering problem, for deep high pressure mine stress is big and superficial part
The surrouding rock deformation problem of soft rock, designs a kind of external poured segmentation anchoring rod, technical support is provided for Safety of Coal Mine Production.
Utility model content
The purpose of this utility model is to develop a kind of external poured segmentation anchoring rod, with simple to operate, anchor force is high, anchor
Gu the features such as section may move.
A kind of external poured segmentation anchoring rod of the utility model, including the body of rod, anchor head, mobile anchoring section, stop grouting plug, support
Disk, nut and filling system, filling system include hydraulic pump and fluid injection gun.The mobile anchoring section can be moved by body of rod screw thread
Dynamic, hydraulic pump can be contacted to mobile anchoring section and anchor head slip casting, slurries and drill hole inner wall by fluid injection gun and reach anchorage effect.
There is the passage flowed for Anchor Agent inside the mobile anchoring section and anchor head, in mobile anchoring section and anchor head outer surface
There is Anchor Agent tap hole.
The rubber hose passes through fluid injection gun by screw thread successively connection fluid injection gun, mobile anchoring section and anchor head, hydraulic pump
To mobile anchoring section and anchor head slip casting, Anchor Agent flows out to reach anchorage effect.
The mobile anchoring section can be moved by screw thread on the body of rod, and mobile anchoring section is adjusted according to the stressing conditions of anchor pole
Position to reach optimal anchoring effect.
The anchor pole is regular screw threads Steel material, can there is multiple mobile anchoring sections on the body of rod.
Compared with prior art, the utility model has following advantageous effects：(1) with traditional Inner anchor external poured anchors
Bar is different, and the utility model grouting mode is that hydraulic pump utilizes rubber hose to mobile anchoring section and anchor head slip casting, Anchor Agent stream
Go out to reach anchorage effect, it is to avoid intensity declines problem caused by the body of rod is hollow.(2) mobile anchoring section can be existed by screw thread
Moved on the body of rod, the position of the mobile anchoring section of rockbolt stress situation regulation can be analyzed to reach optimal anchoring effect, mobile anchoring
Section is settable multiple.(3) external poured anchor pole solve that the attachment of conventional anchor Anchor Agent is uneven and the problem of anchor force declines.
