3) 4, transportation route outside transportation route and hole in hole, in described hole transportation route be monorail transit circuit and track 5 on described monorail transit circuit is provided with multiple can track 6, described meeting track 6 is understood track for simple turnout and is arranged on the same side of transportation route track 5, outside described hole, transportation route comprises the swinging room be communicated with transportation route in hole, and to be communicated with described swinging room unload slag area, material loading and emergent district and charge maintenance district and parking area, described swinging room comprises at least two tune paths 7 and stretches out hole fractional orbital 5 by track switch and transportation route in hole and is connected, described unload slag area comprise unload quarrel platform 8 and at least two unload be cut path 9, the described quarrel path 11 that unloads is communicated with swinging room with track by track switch, described material loading district of meeting an urgent need comprises feeding platform 10 and a material loading path 11 be connected with swinging room, the parking path 13 that described charging maintenance district and parking area comprise charging house 12 and be communicated with turning basin.
The first width in described hole in multiple meeting track 6 can be arranged on distance, 100 meters, tunnel face in track, arranges a meeting track afterwards every 400 meters.
The abutment wall 2 of described meeting track side digs 40cm.
The described meeting long 42m in track 6, required tunnel is wide is 546cm.
Described track comprises rail and sleeper, described rail is 43kg/m rail, and sleeper comprises sleeper and is arranged on the steel sleeper at track switch and bend place, and described sleeper adopts 15cm × 15cm × 150cm lumps of wood, described steel sleeper is the steel sleeper that 140B channel-section steel is made, and steel sleeper length is 150cm, gauge is 60cm.
See Fig. 5-Fig. 7, the using method of above-mentioned light section super long tunnel transportation system is as follows:
1), before muck removal, 7 effectively fill quarrel for 20m
3sK-25 rail storage battery shuttle car composition transport trainset enter in Tunnel, first row shuttle car 4 wherein in transport trainset rests in face 3 and digs installation below, secondary series shuttle car 4 to rest on first meeting track near face 6,3rd row shuttle car 4 rests on face second meeting track 6, the like, until the shuttle car 4 in transport trainset is all stopped;
2) first row shuttle car 4 fill quarrel the complete face that sails out of dig installation, and by the secondary series shuttle car 4 resting in forefront be supplemented to dig installation below dress quarrel, the like, until muck removal terminates;
3) after traction locomotive traction shuttle car 4 loaded vehicle is appeared, rest in swinging room, the decoupling device pushing tow shuttle car 4 that turns around unloads quarrel to unloading quarrel platform 8;
4) traction locomotive draws unload the shuttle car after quarrel 4 to swinging room, rests on the tune path 7 of swinging room, and decoupling device turns around pushing tow shuttle car to quarrels to be installed such as Tunnel inner orbit routes 5;
5) step 1) to 4 is repeated), until muck removal terminates.
The described quantity often circulated into the capable transport vehicle of rail in the capable transport trainset of hole rail effectively fills quarrel amount by a circulation muck removal amount and the capable transport vehicle of rail and determines.
Single time quarrel car flow chart Time Calculation
Use above-mentioned transportation system and transportation resources list to plow quarrel car flow chart and required time is: dress quarrel 1. → draw row muck removal to be transported to 2. in the hole outside → to change planes head 3. → carry out unloading quarrel 4. → change planes head 5. → carry out empty wagons to be back to face dress and to be cut 6.
Fill the quarrel time 1.:
25m
3shuttle ore deposit (effectively dress quarrel 20m
3)
T①=20/200*60=6min。
Row muck removal is drawn to be transported to outside hole the time 2.:
Heavy loading locomotive hauling speed 8km/h; Maximum haul distance 3.2km in secure tunnel import hole, haul distance 0.1km outside hole, total maximum haul distance 3.3km.
T②max=s/v=3.3/8=0.41h=25min。
Change planes head 3., change planes head 5.:
T③=T⑤=6min
4. implementation unloads quarrel:
T④=6min
Carry out empty wagons and be back to face dress quarrel 6.:
Unloaded locomotive traction speed 16km/h; Maximum haul distance 3.2km in secure tunnel import hole, haul distance 0.1km outside hole, total maximum haul distance 3.3km.
T⑥max=s/v=3.3/16=0.21h=12min。
In running, lane change and time of cars meeting are 7.:
T⑦=5min
Single time quarrel car flow chart circulation timei:
Tmax=T①＋T②max＋T③＋T④＋T⑤＋T⑥max＋T⑦=66min
Secure tunnel import goes into operation on September 10th, 2013, on March 26th, 2015 smoothly and 1# inclined shaft secure tunnel importer to through, always 562 days consuming time, complete tunnel piercing 3320m, day comprehensive average advance index 6.0m/ days, wherein III grade of per day progress indicator of country rock reaches 9m/ days, and the highest monthly driving progress is 325 meters, the highest daily progress 13.6 meters.
This example sufficient proof the utility model can well solve light section super long tunnel because of section little, in-cavity construction tissue difficulty; Tunnel is long, and face ventilation difficulty is large waits difficulty, can realize rapid construction driving, shorten project duration, especially concerning this working design EPC Project, meet structure function, the duration, prerequisite under, embodied huge economic benefit.
