Abstract
The invention particularly relates to a temporary support method of a tunneling working face, and equipment thereof. The tunneling working face is divided into a temporary support area and a permanent support area; the temporary support area consists of a tunneling machine and a working area of the tunneling machine, and the area behind the temporary support area is the permanent support area; the temporary support area adopts self-telescopic tunnel hydraulic brackets and bracket moving auxiliary devices in match to achieve firstly support and secondly return; the permanent support and cutting of the tunneling machine can be performed simultaneously. As the tunneling working face is divided into the temporary support area and the permanent support area, simultaneous working of temporary support and permanent support and permanent support and cutting of the tunneling machine is achieved. As the temporary support area is supported and protected by using the temporary support area and a permanent support area; the problem that the surrounding rock is damaged by repeated support is effectively solved.
Description
Technical field
The present invention relates to laneway support method and the equipment thereof of the safe and efficient rapid construction of a kind of underground construction.
Background technology
Underground construction comprehensive mechanized driving construction technology, because it is safe and reliable, singly enter efficiency far above traditional big gun tunneling process, at present by wide popularization and application.A circulation of comprehensive mechanized driving construction technology main consuming time is tunneling machine cutting and roadway support.How to realize tunneling machine cutting and roadway support parallel operations, from eighties of last century the fifties so far, Mining At Home And Abroad circle has carried out a large amount of explorations, and has produced a lot of technology and equipment.Wherein main technology point relates to two aspects, i.e. the safe and reliable temporary lining of Rapid Implementation and the parallel operations of tunneling machine cutting and permanent support.
Temporary lining is to hurt sb.'s feelings for preventing after tunnel initating that country rock drops to cave in; for guaranteeing what permanent support operating personnel's safety was established; 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; can not do temporary lining; directly carry out permanent support; roadway construction is generally wanted first near boring head, to implement temporary lining after roadway excavation, implements the permanent support in tunnel under the protection of temporary lining.
Existing digging laneway temporary support mode mainly contains 6 types:
1, traditional temporary lining mode has suspension ring to add steel pipe (or track, shaped steel) etc., by front altering steel pipe (or track, shaped steel) etc., adds and protects topping material temporary lining top board.
2, development machine rack joist protects top mode.
3, pick anchoring integral development machine.
4, front-back pull-push type or in pairs step type hydraulic pressure automatic shifting stand alternately.
5, the monorail crane timbering machine of Germany's development.
6, TBM tunnel construction development machine temporary lining form.
The subject matter that existing temporary lining exists:
While 1, altering before traditional temporary lining need artificial lapping, on connect topping material; labour intensity is large, and the lower operation in empty top is dangerous, and roof timbering power is not almost had; can only play limited protective effect 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 full section, frame strength and limited with development machine bonding strength, supporting power is very little, and while implementing temporary lining and permanent support, development machine just cannot parallel operations.
3, pick anchoring integral development machine.From sixties first generation anchor driving machine, be born and carried out so far twice change, third generation pick anchoring integral, although realized the parallel operations of pick anchor, but anchor pole unsupported back span is large, generally, more than 1.2-1.5 rice, supporting can not be immediately following meeting head on, so, be only applicable to that Bian is dark little, little, the preferably large Cross-Section Rectangular of wall rock condition is pressed in ore deposit or trapezoidal tunnel, therefore, never applied widely.As countries such as China overwhelming majority mining areas and Germany, Poland, open the Bian degree of depth darker, ore deposit is pressed large, the conditions such as country rock soft broken, anchor pole is intensive, even also need linked network, 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 synchronize with cut.
4, front-back pull-push type or in pairs step type hydraulic pressure automatic shifting stand alternately, each circulation is supported once repeatedly to top board, destructible top board; be unfavorable for the supporting to top board; when roof condition is bad, supporting must 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.Can realize the mechanized operation of permanent support, 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, phase mutual interference, affects parallel operations efficiency.
6, TBM rock ripper has worn-out open type, two shield, single shield etc., and tunnel construction temporary lining form is and the integrated support pattern of full section cut development machine.This support pattern boring head is the integrated support to country rock, contraction, reach by shield total length, supports the supporting of top side, repeatedly support destructible country rock, large, the large section of the radius of curvature that is only applicable to turn round, the good tunnel construction of wall rock condition, chance tomography, zone of fracture are easily stuck.
