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.The mainly consuming time of comprehensive mechanized driving construction technology one circulation 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 creates a lot of technique and equipment.Wherein main technology point relates to two aspects, the temporary lining that namely Rapid Implementation is safe and reliable and the parallel operations of tunneling machine cutting and permanent support.
Temporary lining is hurted sb.'s feelings for country rock after preventing tunnel initating drops to cave in; establish for ensureing the safety of permanent support operating personnel; 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; temporary lining can not be done; 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., adds protect topping material temporary lining top board by front altering steel pipe (or track, shaped steel) etc.
2, development machine rack joist protects top mode.
4, front-back pull-push type or paired alternately step type hydraulic pressure automatic shifting stand.
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:
When altering before 1, traditional temporary lining need artificial lapping, on connect topping material; 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, anchoring integral development machine is dug.Be born from sixties first generation anchor driving machine and carried out twice change so far, 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, 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, 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 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.

Step 5: reach crane, to temporary support area front end, controls the jack on self extending hydraulic support, makes it land on the ground; Adjustment self extending hydraulic support height, receives button and hangs jack, releases clamp, retreat crane, and pack up expansion rail or folding rail;
Step 6: control self extending hydraulic support and make itself and back close contact, complete the temporary lining of back;
Step 7: unclamp the hydraulic pressure automatic fixer I on carriage, stretch hanging beam from moving jack, make hydraulic pressure automatic fixer I aim at lifting hole(eyelet) after arriving desired location, the piston of hydraulic pressure automatic fixer is buckled in lifting hole(eyelet), complete the fixing of hydraulic pressure automatic fixer I; Unclamp the hydraulic pressure automatic fixer II on draw beam, contracting hanging beam from moving jack, and drives hanging beam and hanger rail to move, and makes hydraulic pressure automatic fixer aim at lifting hole(eyelet) after arriving desired location, the piston of hydraulic pressure automatic fixer II is buckled in lifting hole(eyelet), completes the fixing of draw beam;
Step 8: development machine continues cut.
