Relation.Additionally, the various specific technique that provides of this utility model and the example of material, but ordinary skill
Personnel are it can be appreciated that the property of can be applicable to of other techniques and/or the use of other materials.
Below with reference to Fig. 1-Fig. 3, the shaft excavation machine according to this utility model embodiment is described.
Specifically, the shaft excavation machine of this utility model embodiment be particularly well-suited to major diameter vertical shaft tunnel excavation driving execute
Work industry, has the advantages such as excavation efficiency is high, safety is high.Specifically, according to the shaft sinking of this utility model embodiment
Machine may include that cutter head assembly and mud system 4, but also may include that support system, aid system etc..
Below, with reference to Fig. 1-Fig. 3, the cutter head assembly according to this utility model embodiment is introduced.
Specifically, cutter head assembly can include that cutterhead 2, guide bore 1 and driving means 3.Specifically, guide bores 1
Be located at the lower section of cutterhead 2, guide bore 1 and the work surface of cutterhead 2 arrange the most down, thus when cutter head assembly is overall to moving down
Time dynamic, guide bores the soil layer physical features soil layer physical features less than cutterhead 2 excavation of 1 excavation, and guide bores the borehole diameter of 1 less than cutter
The borehole diameter of dish 2, thus guide bore 1 excavation hole footpath, final hole less than thus hole final of cutterhead 2 excavation
Footpath, hole.Further, driving means 3 can fixedly mount in the shield body 5 being described below, driving means 3 and cutterhead 2
Bore 1 to be connected to drive cutterhead 2 and guide to bore 1 and carry out borehole construction operation with guide, say, that cutterhead 2 and guide bore
1 all provides moment of torsion to rotate to implement borehole excavation operation by driving means 3.
So, cutter head assembly, as the excavation part of shaft excavation machine, can use excavation section by section to synchronize during work
Carrying out, say, that at synchronization, guide bores the excavating sequences of 1 pilot hole 10 carrying out next perpendicular borehole section, cutterhead
2 excavating sequences carrying out the upper one cutterhead reaming erecting borehole section, thus, it is possible to the synchronization realizing continuous two sections of perpendicular borehole sections is opened
Dig, drastically increase excavation efficiency.In other words, for same perpendicular borehole section, first bored 1 by guide and the soil body is carried out one
Secondary excavation, formation circle pilot hole 10, then carried out secondary excavation by cutterhead 2, formed and be looped around pilot hole 10 soil body
Outer annular counterbores so that each perpendicular borehole section all by guide bore 1 and the priority of cutterhead 2 excavate continuously and obtain, from
And improve excavation efficiency and borehole effect.
Thus, according to the cutter head assembly of this utility model embodiment, the progress of construction can be effectively improved, reduce cutterhead 2
Bore 1 moment of torsion born with guide, improve the functional reliability of cutter head assembly.It is additionally, since guide and bores 1 all the time prior to cutterhead
2 thereunder excavate pilot hole 10, thus the dregs of cutterhead 2 excavation can bore 1 excavation in pilot hole 10 with guide
Dregs is sufficiently mixed, and is effectively discharged by mud system 4 hereinafter described, thus conveniently slags tap and slag discharge efficiency height.Separately
Outward, owing to cutter head assembly is during excavating, owing to pilot hole 10 is always located in bottom, big when mining process occurs
During the emergencies such as retention of excessive fluid, pilot hole 10 may be used for storing retention of excessive fluid and and being gushed in time by mud system 4 hereinafter described
Water is discharged, and reserves the more time for emergency processing, improves the safety coefficient excavated.
In a specific embodiment of the present utility model, guide bores the 1 multiple drill bits including arranging the most successively (i.e.
