Description
Technical field
The utility model relates to subsurface excavation engineering equipment field, specifically, relates to a kind of sectional shelf-unit and self-advancing Device thereof of laneway temporary support.
Background technology
It is that the strengthening supporting temporary lining of setting and driving face meet head on to cave in as country rock inbreak after preventing tunnel initating to hurt sb.'s feelings that the temporary lining of mine down-hole tunnel comprises face outlet tunnel, and the temporary lining of establishing.The common feature of this two classes temporary lining will move forward along with the propelling of getting working face.
Traditional face temporary lining withdraws carrying and installation and manually carries out, and worker's labour intensity is large, and employment is many, efficiency is low, supporting intensity is low, and safety is unreliable.In recent years, along with the development of mining equipment technology, have part fully-mechanized mining work plane to export lame advanced supporting use pull in front and others push behind or replace walking type hydraulic supports, this hydraulic support is move towards supported laneway top board along tunnel mostly, although bracket support intensity is large, hydraulic pressure is from moving, solve labour intensity and the safety problem of worker, but support rolls anchor shaft anchor cable repeatedly, the original roadway support of heavy damage, owing to pulling in front and others push behind or alternately taking a step to there is repeatedly the destruction of support unloading to back, application is difficult to when the large roof cracking of Tunnel Pressure.
Digging laneway temporary support is the main security facility of driving face.More shallow and Surrounding Rock Strength is high, self-supporting is reliable and stable after excavation, geological structure is simple etc. the applicable condition for mining depth, mechanical system is adopted to carry out permanent support, operating personnel does not need to enter empty top zone, can not do temporary lining, directly carries out permanent support.But generally, want first near boring head, to implement temporary lining after roadway excavation, under the protection of temporary lining, implement the permanent support in tunnel.Existing digging laneway temporary support and adopt mechanical system to carry out permanent support and mainly contain 6 types, these temporary lining modes are all at existing defects in varying degrees.
1, traditional temporary lining mode has suspension ring to add steel pipe (or track, shaped steel) etc., adds protect topping material temporary lining top board by front altering steel pipe (or track, shaped steel) etc.Need artificial lapping when altering before temporary lining, manually topping material be installed; labour intensity is large, and the lower operation in empty top is dangerous, does not almost have roof timbering power; limited protective effect can only be played to operating personnel, often occur that field operation personnel follow the line of least resistance, dislike trouble, do not use phenomenon.
2, development machine frame joist type temporary lining, lapping operation is still under sky top, and supporting area does not reach tunneling boring, frame strength and limited with development machine bonding strength, and supporting power is very little, and when implementing temporary lining and permanent support, development machine just cannot parallel operations.
3, dig anchoring integral development machine and carry out twice change so far from sixties first generation anchor driving machine birth, third generation pick anchoring integral, although achieve the parallel operations of pick anchor, but anchor pole unsupported back span is large, and generally more than 1.2-1.5 rice, supporting can not immediately following meeting head on, so, be only applicable to that Bian is dark little, ore deposit pressure is little, wall rock condition good big cross section rectangle or trapezoidal tunnel, therefore, never applied widely.The Bian degree of depth is opened darker as China overwhelming majority mining area and the country such as Germany, Poland, ore deposit pressure is large, the conditions such as country rock soft broken, anchor pole is intensive, even also need linked network and cable bolting, support work amount is large, and not only unsupported back span is from can not meet requirement, support time, much larger than the cut time, is also difficult to synchronous with cut.
4, front-back pull-push type or paired alternately step type hydraulic pressure automatic shifting stand, each circulation supports once repeatedly to top board, destructible top board; be unfavorable for the supporting to top board; when roof condition is bad, must supporting be shut down, tunneling machine cutting and permanent support parallel operations can not be realized.
5, the monorail crane timbering machine of Germany's development.The mechanized operation of permanent support can be realized, avoid personnel to enter the operation of non-support district, but this device structure is too complicated, appearance and size is large, can only be applicable to large section roadway construction, and supporting and driving cut are at the same area, mutually dryly to scratch, affect parallel operations efficiency.
6, TBM rock ripper has worn-out open type, two shield, single shield etc., and tunnel construction temporary lining form is the support pattern integrated with tunneling boring cut development machine.The supporting of this support pattern boring head to top side is to integrated support, contraction, the reach of country rock, support by shield total length again, repeatedly support destructible country rock, being only applicable to turn round, radius of curvature is large, the good tunnel construction of big cross section, wall rock condition, meets tomography, zone of fracture is easily stuck.
Therefore, how designing a kind of brand-new device, realize the temporary lining in tunnel, is the problem that those skilled in the art urgently need solve.
