Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail:
Referring to Fig. 1 to Fig. 3, a kind of TBM supporting operation packaged type protection shield, this device includes canopy body 1, support column 2, column sleeve 3, hydraulic jack 4, workbench 5, road wheel 6, protection wheel 7, track 8, horizontal power system 9.Canopy body 1 is made up of curved plate 10 and steel pipe 11, and curved plate 10 radius of curvature is identical with tunnel excavation face, and is provided with the preformed hole of steel pipe 11 coupling, and steel pipe 11 inserts in curved plate 10 preformed hole and carries out weldering junction formation canopy body 1.The weight of canopy body 1 reaches the track 8 on ground by support column 2 and hydraulic jack 4, the top of hydraulic jack 4 is against on canopy body 1, bottom is connected to the ear mount being fixed on column sleeve 3, crossbeam is had to couple between column sleeve 3, ear mount is welded on described crossbeam, the hole pin shaft joint of the earhole of hydraulic jack 4 and ear mount, ear mount is positioned at the top of workbench 5.Under hydraulic jack 4 acts on, support column 2 in column sleeve 3 slidably, can promote or reduce canopy body 1.To be locked out when support column 2 is down to workbench 5, it is prevented that canopy body 1 continues to glide and guarantees the safety of personnel and equipment on workbench 5.Workbench 5 bottom is provided with road wheel 6 and protection wheel 7, and top weight is transferred to track 8 by road wheel 6, and protection wheel 7 is positioned at track 8 bottom, is mainly used to prevent protection shield from derailing in the process of walking.Plate Welding is adopted to prevent track deformation between two tracks 8.Protection shield horizontal power system 9 is made up of motor 12, worm-gear speed reducer 13, driving wheel 14.The rotating speed of motor 12 is decelerated to rotating speed of target by worm-gear speed reducer 13, drives protection shield advance or retreat under the effect of driving wheel 14.
In TBM work progress, first, protection shield rests in tunnel supporting region, carries out mesh sheet splicing operation on canopy body 1 top；After protection shield rear country rock discloses, protection shield is pushed into country rock and discloses district, carry out mesh sheet installation；Under the protection of protection shield, carry out anchor bolt construction by jumbolter hole 15；After anchor bolt construction completes, protection shield is retracted again tunnel supporting district.
Adopting this protection shield, when the once supporting operation of TBM, canopy body 1 top can carry out mesh sheet connection work in advance, after excavation face releases protection shield, once completes the connection of mesh sheet within the scope of canopy body, it is possible to significantly improve once supporting efficiency.Meanwhile, in anchor bolt construction process, protection shield can prevent country rock face bulk falling rocks, can effectively protect the safety of workmen and equipment.
Below operating process of the present utility model is described in detail:
Packaged type of the present utility model protection shield includes canopy body 1, support column 2, column sleeve 3, hydraulic jack 4, workbench 5, road wheel 6, protection wheel 7, track 8, horizontal power system 9.Canopy body 1 is made up of curved plate 10 and steel pipe 11, curved plate 10 has steel pipe preformed hole, steel pipe 11 insert in steel pipe preformed hole, carries out weldering knot in insertion point.Support column 2 is limited in column sleeve 3 in horizontal plane, can move up and down under hydraulic jack 4 acts in column sleeve 3.Column sleeve 3 bottom is fixed on workbench 5.Road wheel 6 bottom contacts with track 8, mainly undertakes top weight.Protection wheel 7 is in order to prevent derailing in protection shield walking process.
During use, according to the following steps:
1. mesh sheet is assembled in advance: in TBM tunneling process, and when protecting shield rear country rock excavation face not yet to disclose, protection shield is positioned at below supporting region.The radius of curvature of curved plate 10 is identical with tunnel excavation face, determines curved plate 10 and the interval of steel pipe 11 according to mesh sheet specification, can carry out mesh sheet assembled in advance, be attached between mesh sheet on the upside of canopy body 1.
2. mesh sheet is installed: after protection shield rear country rock excavation face discloses, opens the motor 12 in horizontal power system 9, worm-gear speed reducer 13 motor 12 rotating speed is down to desired value, and power passes to driving wheel 14.Protection shield level is pushed into below exposure scar by driving wheel 14.Then, liquefaction oil cylinder 4 being pressurizeed, by support column 2 by canopy body 1 vertical lifting until pressing close to excavate scar, carrying out mesh sheet installation.
3. anchor bolt construction: after mesh sheet installation, keeps protection shield motionless, adopts jumbolter to carry out bolthole construction by the jumbolter hole 15 in canopy body, and bolthole carries out rockbolt installation after having constructed.After one rockbolt installation completes, carry out the construction of other position anchor pole by adjusting canopy body position.
4. protection shield resets: after canopy body region mesh sheet and anchor bolt construction complete, for convenience of the carrying out of follow-up supporting operation, it is necessary to protection shield is retracted supporting position.First, shrink hydraulic jack 4 and reduce canopy body 1, make canopy body 1 depart from country rock；Then by startup horizontal power system 9, canopy body 1 is pulled out supporting position.
5., along with TBM constantly tunnels forward, complexity carries out above-mentioned steps and constantly carries out initial support operation.
Protected the utilization of shield by this TBM supporting operation packaged type, unsupported area mesh sheet and anchor bolt construction can carry out under the protection of canopy body, can effectively prevent unsupported area landslide and falling rocks, effectively protection supporting construction personnel and plant equipment.Meanwhile, within the scope of canopy body, the pre-splicing work of mesh sheet can carry out with TBM driving simultaneously, it is possible to increase once supporting efficiency.
