Description
Technical field
The present invention relates to a kind of processing method, especially a kind of TBM cutterheads and shield card machine processing method.
Background technology
Currently, during big tunnel, for efficient, environmentally friendly and safe consideration, widely used TBM is dug
Pick.But since geology influences, when tunneling construction is by unfavorable geology section, often since country rock is extremely broken, lead to TBM
Cutterhead and shield occur by card phenomenon.After some TBM card machine accidents occur, since TBM failures of getting rid of poverty yield TBM and are changed
Line processing, causes great loss.
Invention content
It is an object of the invention to provide it is a kind of quick and convenient can make TBM take off TBM cutterheads that cutterhead and shield are got rid of poverty and
Shield card machine processing method.
It is realized the purpose of the present invention is technical solution in this way, a kind of TBM cutterheads and shield card machine processing method,
Described method includes following steps：
（1）, excavate longitudinal small pilot tunnel；
Hand excavation's longitudinally small pilot tunnel, the synchronous vertical longitudinal small pilot tunnel of branch are carried out from the metastable position of shield tail portion country rock
Gate steelframe, longitudinal small pilot tunnel pass through the areas slump Cha Ti.
（2）, several small pilot tunnels of annular of small pilot drive along longitudinal direction；
By the small pilot tunnel in the longitudinal direction excavated by shield and cutterhead by being divided into several small pilot tunnels of annular, subregion excavation section by section ring
The small pilot tunnel of shape, the synchronous vertical small pilot tunnel gate steelframe of annular of branch, the small pilot tunnel gate steel frame column bottom of annular are welded on shield, directly
To excavation supporting to requiring position.
（3）, pass through steel construction and carry out supporting and reinforcing；
（4）, TBM slowly driving pass through shear-zone.
By the small pilot tunnel of annular being excavated, outer annular steel arch is erected in the small pilot tunnel gate steelframe below the crossbeam of annular
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；
Soldering and sealing steel plate on the inside of internal layer annular steel arch-shelf, concrete perfusion backfill is close in outer annular steel arch-shelf and internal layer annular steel arch-shelf
It is real, after concrete strength reaches design requirement, gate steel frame column is cut off, completes interim gate steelframe support system to finally
Annular steelframe support system conversion.
Wherein, in order to improve safety, forward grouting anchor pile slip casting is performed before longitudinal small pilot tunnel and the small pilot drive of annular,
Reinforce front country rock.
By adopting the above-described technical solution, the present invention has the advantages that quick and convenient, construction procedure is few, safe and reliable,
Processing of getting rid of poverty is carried out to the cutterhead and shield of TBM using this method, not only safe operation, but also can be within the extremely short time
It will 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, which is got rid of poverty, 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：Supporting schematic diagram after the TBM cutterheads and shield of the present invention is got rid of poverty.
Specific implementation mode
Specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings, 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 and is wanted
Seek the range of protection.
Embodiment 1：As shown in Figure 1, 2, 3, a kind of TBM cutterheads and shield card machine processing method, the method includes as follows
Step：
（1）, excavate longitudinal small pilot tunnel；
（2）, several small pilot tunnels of annular are excavated in small pilot tunnel along longitudinal direction；
（3）, pass through steel construction and carry out supporting and reinforcing；
（4）, TBM slowly driving pass through shear-zone.
Wherein, above-mentioned（1）In step, concrete operations are as follows：From the 1 metastable position of tail portion country rock of shield into pedestrian
Work excavates longitudinal small pilot tunnel 2, the synchronous vertical longitudinal small pilot tunnel gate steelframe 3 of branch, and longitudinal small pilot tunnel 2 passes through the areas slump Cha Ti 11.
Wherein, above-mentioned（2）In step, concrete operations are as follows：By the small pilot tunnel 2 in the longitudinal direction excavated by shield 1 and knife
Disk 4 founds the small pilot tunnel gate steel of annular by the small pilot tunnel 5 of several annulars, the small pilot tunnel 5 of subregion excavation section by section annular, synchronous branch is divided longitudinally into
Frame 6, small 6 column bottom of pilot tunnel gate steelframe of annular are welded on shield 1, until excavation supporting is to requiring position.
Wherein, above-mentioned（3）In step, concrete operations are as follows：It is small in annular by the small pilot tunnel 5 of annular being excavated
7 lower section of pilot tunnel gate steelframe crossbeam erects outer annular steel arch-shelf 8 and internal layer annular steel arch-shelf 9, 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 inside soldering and sealing steel plate of internal layer annular steel arch-shelf, outer annular
