Embodiment
For the technical characterstic for illustrating this programme can be understood, below by an embodiment, and its accompanying drawing is combined, it is right
This programme is illustrated.
Name involved by the application is done explained below：
Supporting：Empty top tunnel after tunneler construction is complete, the permanent support of progress.
Two fortune：Two belt conveyers supporting with development machine.
The two anti-sides of fortune：After development machine is turned to certain position, two belt conveyers, along right side 16, make against 1511 skins
Development machine can not be further continued for constructing forward.
Cutting arm：On development machine, what is be connected between cutterhead and body cranks arm.
Cut scope：When development machine swings cutterhead, the boundary of works area that can reach.
The amplitude of oscillation：When development machine swings cutterhead, the full-size that can reach.
Pendulum machine：Development machine drives development machine not by crawler travel, but by cutterhead branch by operating cutting arm
It is mobile.
The construction method that EBZ160 development machines acute angle is turned, including following construction procedure,
Step 1：Determine min. turning radius,
When designing tunnel turning, fuselage is longer, and required radius of turn is bigger, and fuselage is wider, and required enabling tunnel is wider, and
Machine body of boring machine height is on turning to without influence.Learnt according to development machine related data, EBZ160 development machine min. turning radius is
6.5m.Because 1511 skins along 15 with to cut eye to lead the angle of cave 14 be 72 °, arrangement at an acute angle, to reduce roof span when turning round, it is determined that
Turned using min. turning radius (6.5m), now roof span is minimum.
Step 2：Theoretical Design simulation is turned,
Before construction, modeling is first made according to tunnel and development machine parameter on CAD and turned, determine that tunnel turns by demonstrating
Curved related data, in analog demenstration, surplus coefficiert is reserved apart from lane side, to ensure that development machine rear molding does not scratch lane side；
When selecting min. turning radius (6.5m), activity space is narrow and small when easily causing development machine turning, advances, retreats difficulty.
But turning length is short, and construction volume is relatively small, as long as development machine activity space can meet operational requirements, now maximum supporting size
18 minimum 11m (select by maximum supporting size：Interior curved center during digging laneway is to tunnel profile most ledge).Work as selection
During more than 6.5m radius of turn, easily cause that area of suspension roof is excessive, cause the unsafe factor of setting, while later stage supporting is stranded
It is difficult.
Step 3,1511 skins split side construction along meeting head on 11 from the construction of 1 straight lane of side opening position is split after permanent support,
（1）1511 skins are first just being met head on along meeting head on 11 from starting to split side opening position 1 by normal cyclic drilling depth 1511 skins of constructing along 15,
After top plate and skin are along 12 permanent supports of left side, then side construction is split by the way of the direct cut of cutterhead.Every meter of circulation when splitting side
Drilling depth is split side cut face and tiltedly faced directly into one from starting point to side end is split；
（2）Split side position：From 1511 cut eye lead cave it is right side 20 and 1511 skins along it is right help 16 point of intersection step back 21m（One whole two fortune
The length of belt conveyer）Opening position, side construction is split by 3 ° of angles 2.For ease of execute-in-place, it need in advance provide and split side size,
That is every meter of cyclic advance extends out 0.05m to 1511 skins along right side 16, and second meter of opening position extends out 0.1m to 1511 skins along right side 16,
It is incremented by successively, split side width 1.05m to 21m opening position maximums.
Step 4, when 1511 skins along 15 construction to 1511 cut eye lead cave it is left side 21 when, development machine steps back 10m, reserve 1511
Cut eye and lead cave enabling mouth 9, and the floor level clicked here plays bottom, horizontal sliding, it is ensured that the bottom plate mark in the range of the 10m of development machine turning
A height of same absolute altitude platform.
Step 5,1511, which cut eye, leads cave self-opening door position, and construction of being turned round in the form of splitting side, it is 1m to split side cyclic advance.
By currently normal connection, it is supporting in a manner of, 1511, which cut eye, leads cave can turn round construction 3m into obtuse angle, and 1511 cut eye and lead cave bottom right side
The construction of 13 corners is less than needing step 10 to construct.
Step 6, when development machine band two, which transports belt construction, reaches the maximum amplitude of oscillation, machine is moved back, makes shovel board of development machine front end extremely
1511, which cut eye, leads at cave enabling mouth 9, and adjusts development machine again, makes on the left of development machine to carry out pick along left side 12 against 1511 skins
The preparation entered before machine turn construction.
Step 7, because working space is limited, field condition limitation, when development machine is advanced into 1511 along 1511 skins along left side 12
After skin is just met head on along 15, advance, retrogressing, left crawler travel, the right-hand track chiain walking of crawler belt are manipulated by, to reach levelling pick
Enter that the construction direction of machine is more difficult, now need to take the mode of driving head effectively to realize flipper turn.That is development machine
Cut crown reality bottom, side angle（Underworkings is the coffin excavated in entity coal petrography, is above top plate, and lower is bottom plate, two
Side is side.Two help and push up, angle in 90 ° between bottom plate, and cutterhead prevents it from again against bottom plate and the angle in portion of side
Continue to portion of side to be moved below inner, bottom plate）, by controlling cutting arm to extend, lower sleeping, shovel board of development machine and crawler belt front end are supportted
Rise,（Now the quality of whole development machine is entirely fallen within cutterhead and two crawler belt rear end fulcrums）, then by controlling cut
Arm turns left to move joystick, its is produced the power to turn left, and because cut crown reality bottom, side junction can not be moved
Dynamic, tail is moved to the left against 1511 skins along left side 12, limitation tail, and the dynamic reaction that now cutting arm turns left is in pick
Enter machine, shovel board of development machine is elapsed to the right to about 20cm finally by reaction force to the right, at this moment development machine slightly bends to right
Afterwards, can continue to construct forward along first rectilinear direction after pendulum machine that turns around.Eye, which is cut, when cutterhead cut to 1511 leads the left side 21 of cave
After design attitude, continue to turn around using above-mentioned identical operating method, pendulum machine is constructed.
Step 8, when development machine repeatedly turns around, pendulum machine to the maximum amplitude of oscillation when, remove development machine and company at belt tails transported with two
Pin axle.After removing bearing pin, development machine separates with two fortune belts.Constructed for ease of turning round, need to be with 2 5T chain block by two
Fortune belt machine end is sling to lap position, then by using special suspension chain of 2 40T, by two fortune tail hangings to driving
Machine one is transported on the hanging nose slipped under head, it is ensured that is flexible coupling firm, effective.
Step 9, when development machine and two fortune belt machine ends be changed to be flexible coupling after, development machine can big swing angle continue to construct.Work as pick
Enter mechanical shovel plate in the 3rd step " construct less than 1511 cut eye and lead cave bottom right help 13 corners " when, shovel board of development machine movement by
Limit, it is impossible to be further continued for cutting eye to 1511 and lead the right side of cave and 20 move down, now crouched under cutting head of roadheader to bottom plate, at the side of shovel board top
For fulcrum, it is set to produce a power to the right by operating cutting arm right turn, as a same reason, because cutterhead, shovel board have been pushed up
Real 1511, which cut eye, which leads the right side 20 of cave, to move right again, and a reaction force to the left is so just generated to development machine, is led to
Operation pendulum machine by force is crossed, reaches the purpose that development machine is wagged the tail, so as to ajust the purpose that development machine reaches turn.
Step 10, continuously put machine to the right because of development machine and turn round, and walk forward so that development machine rear have it is certain
The safe space constructed, at this moment the development machine after ajusting is retreated to 1511 skins along left side 12, now shovel board of development machine is no longer
It is mobile restricted, turn direction can be adjusted again, and 1511 not constructed by the original step 5 of cutterhead cut construction are cut eye and led
13 corners are helped in cave bottom right, cut eye by 1511 and lead cave and meet head on that brush is neat, centering.
Step 11, development machine centering continue to construct forward after meeting head on, until the two anti-sides of fortune belt holder（Because of development machine and two
Belt or connection mode are transported, when development machine turn construction flushes to two fortune tails with 1511 skins along right side 16, two fortune belts
Frame by 1511 skins along it is right side 16 entity coal stop, cause development machine can not band two fortune continue construct forward）, now 1511 cut eye
Lead cave turned round construction about 10.9m（Split the side long 0.6m of deep 1m+ driving captain's 9.3m+ telescoping cylinders）.
Step 12, when development machine can not continue to construct forward, mark 1511 cut eye lead cave construction center line 19, development machine
Band two is transported along center line 19 and moves back machine to 1511 skins along left side 12, now removes being flexible coupling for two fortune belt tails, and transport belt tail by two
Place, and be fixed on roadway floor along left side 12 by 1511 skins, development machine is then reached 1511 cut eye and lead cave construction
Meet head on 11, a 40T scraper-trough conveyer transshipment is laid between development machine and two fortune belt tails.
Step 13, continue to construct forward by way of development machine rides 40T scraper-trough conveyer transshipments and 1511 cut eye and lead cave 40m
Afterwards, the 40T that dismantles slips head, two sections, removes two fortune belts and is transported to 1511 and cut eye to lead cave standby, then by 1511 skins along 15
Interior contracting belt tail draws to move on to 1511 and cut eye and lead and fixed at cave enabling mouth, lays 40T again and slips head, two sections, it is ensured that overlap joint closes
