Top and guilder two-in-one tunnel boring machine
Technical field
The present invention relates to a kind of tunnel machine, particularly a kind of top and guilder two-in-one tunnel boring machine.
Background technology
Usually adopt Mine Method, shield method and construction by pipeline jacking method for underground large tunnel tunneling construction in the world at present, Mine Method generally is used for the geological conditions of stone matter, becomes cavern with Blasting Excavation, builds interior wall then and build up the tunnel in cavern.Shield method or pipe jacking method relatively are suitable for the tunneling construction of the city subterranean tunnel of weak soil geological conditions, shield construction is exactly that the front is with having the driving head driving that cuts cutterhead, with assembling machine the piecemeal lining cutting is assembled into ring-type lining cutting circle at the development machine back of head, and tunnel lining is no longer mobile after installing.The construction by pipeline jacking method front is also with having the driving head driving that cuts cutterhead, all tunnel tube couplings of back are along with the driving of development machine moves ahead, be exactly that tunneling construction begins to finish until jacking, tube coupling constantly adds in the back and constantly pushes ahead with tunneling construction always.The diameter in general tunnel adopts the shield method operation in that the length more than 4 meters is most in apart from constructing tunnel, adopts the pipe jacking method operation and the short-distance and medium-distance tunnel of diameter below 4 meters is most.Because the main cost of production of tunnel machine is in the development machine head part, push pipe tunnel machine and shield tunnel development machine are basic identical in the part of driving head, only are to tunnel the structure function difference of head rear end part.And now general constructing tunnel unit is in order to finish the work, need to prepare or order two kinds of different tunnel machines, the cost of set of tunneling construction will be increased, and produce tunnel machine with top shield unification, will be reduced in the cost of production of constructing tunnel unit in accepting constructing tunnel greatly.
Summary of the invention
The objective of the invention is to solve constructing tunnel unit in the prior art increases the constructing tunnel equipment cost in order to accept construction of tunnel need prepare two kinds of different tunnel machines in urban construction problem, a kind of top and guilder two-in-one tunnel boring machine is provided.The present invention designs a kind of top and guilder two-in-one tunnel boring machine, comprises the tunnel piercing head, it is characterized in that: in tunnel piercing head rear end the connection end face is arranged, with union end is joining push pipe tube coupling socket joint device or shield structure assembly unit device arranged.Push pipe tube coupling socket joint device is a tube coupling socket joint ring.Shield structure assembly unit device is made up of oil cylinder jacking mechanism, assembly unit mechanism and shield tail sealing mechanism, above-mentioned three mechanisms are installed in the housing, the jacking oil cylinder is positioned at the front portion of housing, and assembly unit mechanism is positioned at the middle part of housing, and shield endnote slurry sealing mechanism is positioned at the rear portion of housing.The front end of this housing connects with the driving back-end of machine head, and the rear end and the tunnel lining of this housing are joined.Advantage of the present invention is to realize the dual-use of tunnel piercing equipment, reduces the cost of constructing tunnel unit's procuring equipment greatly.

The specific embodiment
Comprise tunnel piercing head 1 among the figure, it is characterized in that: at tunnel piercing head 1 rear end face union end 2 is arranged, push pipe tube coupling socket joint device 3 or shield structure assembly unit device 4 arranged with union end 2 is joining.Push pipe tube coupling socket joint device 3 is a tube coupling socket joint ring 5.Shield structure assembly unit device 4 is made up of oil cylinder jacking mechanism 10, assembly unit mechanism 6 and shield tail sealing mechanism 7, above-mentioned three mechanisms are installed in the housing 8, the jacking oil cylinder 9 of oil cylinder jacking mechanism 10 is positioned at the front portion of housing 8, assembly unit mechanism 6 is positioned at the middle part of housing 8, shield endnote slurry sealing mechanism 7 is positioned at the rear portion of housing 8, the front end of this housing 8 connects with the union end 2 of tunnel piercing head 1 rear end, and the rear end and the tunnel lining of this housing 8 are joined.
In the practice of construction, the tunnel piercing head 1 of tunnel machine is the main equipment of whole tunnel machine, it takies more than manufacturing cost more than half, it is important component parts of whole tunnel machine that cutting cutterhead, drive unit, dregs conveying, deviation correction mechanism etc. are arranged in tunnel piercing head 1, therefore the push pipe tunnel machine of original single effect, the driving of shield tunnel development machine are partly formed and can compatibility be tunneled head, the tube coupling socket joint ring 5 of changing-over push-bench or shield structure assembly unit device 4.Can reduce the acquisition cost of main equipment greatly, lay the first stone for unit in charge of construction reduces construction cost.
Specifically be if carry out constructing tunnel with the jacking construction method, the union end 2 of tunnel piercing head 1 rear end can be connected tube coupling socket joint ring 5 to form the push pipe tunnel machine, the push pipe tunnel machine is placed in the tunneling well, tube coupling socket joint ring 5 parts at the push pipe tunnel machine are carried out the assembly unit of tube coupling, then along with the driving of push pipe tunnel machine, constantly repeat in active well, to carry out the tube coupling assembly unit and pursue the joint jacking, up to whole jacking constructions of finishing the push pipe tunnel.
When needing shield construction, the union end 2 at tunnel piercing head 1 rear portion can be connected shield structure assembly unit device 4 and form the shield tunnel development machine, the shield tunnel development machine is placed in the tunneling well, cutting stratum dregs in the shield tunnel driving, by conveying device dregs is sent the tunnel, and by jacking oil cylinder 9 tunnel piercing head 1 is advanced and to move ahead, whenever the distance that the lining papers that moves ahead is built, shield tunnel development machine assembly unit mechanism 6 will finish a ring-type lining cutting assembly unit, finish once interval driving up to the shield tunnel development machine.
