The method is adopted to conduct release operation on a cutterhead and a shield of the TBM, operation is safe, and the jammed cutterhead and a jammed shield machine of the TBM can be released in an extremely short time, so that cost is reduced, and time is shortened.
Description
Technical field
The present invention relates to a kind of processing method, particularly a kind of TBM cutterheads and shield card machine processing method.
Background technology
At present, during big tunnel, for efficient, environmentally friendly and safe consideration, widely used TBM is dug
Pick.But, as geology affects, when tunneling construction passes through unfavorable geology section, Jing is often extremely broken due to country rock, causes TBM
Cutterhead and shield occur by card phenomenon.After some TBM card machines accidents occur, as TBM failures of getting rid of poverty yield TBM and are changed
Line process, causes greatly loss.
The content of the invention
It is an object of the invention to provide a kind of TBM cutterheads that the de- cutterheads of TBM and shield quick and convenient can be made to get rid of poverty and
Shield card machine processing method.
The purpose of the present invention realized by such technical scheme, a kind of TBM cutterheads and shield card machine processing method,
Methods described comprises the steps：
（1）, excavate the little pilot tunnel in longitudinal direction；
Hand excavation's longitudinally little pilot tunnel, synchronous vertical longitudinal little pilot tunnel gate are carried out from the metastable position of shield afterbody country rock
Steelframe, the little pilot tunnel in longitudinal direction pass through slump Cha Ti areas.
（2）, along some annular little pilot tunnels of the little pilot drive in longitudinal direction；
Will be shield and cutterhead little by some annular little pilot tunnels, subregion excavation section by section annular is divided into by the little pilot tunnel in the longitudinal direction excavated
Pilot tunnel, synchronous is found annular little pilot tunnel gate steelframe, and annular little pilot tunnel gate steel frame column bottom welding is on shield, until opening
Supporting is dug to requiring position.
（3）, supporting and reinforcing carried out by steel construction；
（4）, TBM slowly driving by shear-zone.
By the annular little pilot tunnel being excavated, outer annular steel arch is erected in annular little pilot tunnel gate steelframe below the crossbeam
Frame and internal layer annular steel arch-shelf, and the configuration reinforcement between outer annular steel arch-shelf and internal layer annular steel arch-shelf as needed；
In soldering and sealing steel plate on the inside of internal layer steel arch-shelf, outer annular steel arch-shelf and internal layer annular steel arch-shelf, concrete perfusion backfill is closely knit, treats
After concrete strength reaches design requirement, gate steel frame column is cut off, interim gate steelframe support system is completed to final annular
Steelframe support system is changed.
Wherein, in order to improve safety, forward grouting anchor pile slip casting is performed before the little pilot tunnel in longitudinal direction and annular little pilot drive,
Reinforce front country rock.
As a result of above-mentioned technical proposal, the present invention has the advantages that quick and convenient, construction procedure is few, safe and reliable,
Process of getting rid of poverty is carried out to the cutterhead and shield of TBM using the method, not only safe operation, but also can be within the extremely short time
To be got rid of poverty by the TBM cutterheads and shield of card, saved cost and time.
Description of the drawings
The description of the drawings of the present invention is as follows：
Fig. 1：The TBM cutterheads and shield of the present invention is got rid of poverty and excavates gib gate steelframe layout diagram；
Fig. 2：The TBM cutterheads and shield of the present invention is got rid of poverty steelframe elevational schematic view；
Fig. 3：The present invention TBM cutterheads and shield get rid of poverty after supporting schematic diagram.
Specific embodiment
Below in conjunction with the accompanying drawings the specific embodiment of the present invention is described in further detail, but the present invention does not limit to
In these embodiments, any improvement or replacement on the present embodiment essence spirit still falls within the claims in the present invention wanted
Seek the scope of protection.
Embodiment 1：As shown in Figure 1, 2, 3, a kind of TBM cutterheads and shield card machine processing method, methods described includes as follows
Step：
（1）, excavate the little pilot tunnel in longitudinal direction；
（2）, excavate some annular little pilot tunnels along the little pilot tunnel in longitudinal direction；
（3）, supporting and reinforcing carried out by steel construction；
（4）, TBM slowly driving by shear-zone.
Wherein, above-mentioned（1）In step, its concrete operations is as follows：Enter pedestrian from the metastable position of 1 afterbody country rock of shield
Work excavates the little pilot tunnel 2 in longitudinal direction, and synchronous is found the little pilot tunnel gate steelframe 3 in longitudinal direction, and the little pilot tunnel 1 in longitudinal direction passes through slump Cha Ti areas 11.
Wherein, above-mentioned（2）In step, its concrete operations is as follows：By the little pilot tunnel 2 in the longitudinal direction excavated by shield 1 and knife
Disk 4 founds annular little pilot tunnel gate steel by some annular little pilot tunnels 5, the little pilot tunnel 5 of subregion excavation section by section annular, synchronous propping up is divided longitudinally into
Frame 6, annular little 6 column bottom of pilot tunnel gate steelframe are welded on shield 1, until excavation supporting is to requiring position.
Wherein, above-mentioned（3）In step, its concrete operations is as follows：It is by the annular little pilot tunnel 5 being excavated, little in annular
Outer annular steel arch-shelf 8 and internal layer annular steel arch-shelf 9 are erected below pilot tunnel gate steelframe crossbeam 7, and as needed in outer layer ring
Configuration reinforcement between shape steel arch-shelf 8 and internal layer annular steel arch-shelf 9；In 9 inner side soldering and sealing steel plate of internal layer steel arch-shelf, outer annular steel arch
