Description
Technical field
This utility model is related to technical field of road construction, specially a kind of slurry-water balance type pipe jacking tunnelling machine.
Background technology
Jacking construction is a kind of construction method of the laying underground piping growing up after Shield Construction Technique, can be
Pass through river course, highway, building etc. in the case of not affecting ground installation to be constructed.Have efficiently, environmental protection the features such as, obtain
More and more it is widely applied.Jacking construction mainly by active well and accept well, main jacking device, foundation ditch guide rail, pipeline and development machine,
Defeated indigenous equipment etc. forms.First install foundation ditch guide rail and main jacking device in active well during construction, then pick is put well on guide rail
Enter machine and tool pipe, by means of the thrust of the thrust instruments such as main top oil cylinder, tool pipe or development machine etc. in active well, push pipe
Construction despite a very advanced technology, but in construction the technical ability of device operator the quality of construction quality is had very big
Impact.How to become technical ability into intelligence, improve the intelligence degree of equipment, reduce the impact to construction quality for the anthropic factor, be mesh
Front urgent problem.How to be set by keeping earth pressure balance to control surface subsidence to propose some improvement in therefore just constructing
Think, to improve the construction quality of engineering.
Utility model content
For problem above, this utility model provides a kind of slurry-water balance type pipe jacking tunnelling machine, is put down by keeping soil pressure
Weigh and to control surface subsidence, can be with the problem in effectively solving background technology.
For achieving the above object, this utility model provides following technical scheme：A kind of slurry-water balance type pipe jacking tunnelling machine, bag
Include main stand, inside described main stand, pipe jacking tunnelling machine be installed, described pipe jacking tunnelling machine by cutterhead oil cylinder, rotary shaft,
Cutterhead and blade row composition, described cutterhead is located at main stand side, and described cutterhead oil cylinder is located inside main stand, described turn
Moving axis passes through main stand, and one end is located in described cutterhead oil cylinder, is located at outside main stand near cutterhead one end, and pacifies above
Equipped with blade row, be provided with a mud discharging mouth above described cutterhead, described mud discharging mouth be provided with controlled valve, described main stand and
Pipe jacking tunnelling machine is integral type structure.
As a kind of preferred technical scheme of this utility model, model NPD2400 of described pipe jacking tunnelling machine.
As a kind of preferred technical scheme of this utility model, described blade row is done down from the high alloy tool steel of intensity
Mould.
As a kind of preferred technical scheme of this utility model, described main stand has guide rail, and on described guide rail
Pulley is installed.
Compared with prior art, the beneficial effects of the utility model are：When pipe jacking tunnelling machine works, main top oil cylinder is forward
Propulsion, with cutterhead oil cylinder in opportunity by cutterhead and the laminating of the soil body head-on, when cutterhead stress balance, cutterhead is in relative to fuselage
Resting state, the mud discharging mouth between cutterhead and blade row is certain value, and sludge volume is certain, earth pressure balance.When soil active force is big, knife
Disk retreats relative to fuselage, and the mud discharging mouth between cutterhead and blade row increases, and so that head-on soil pressure is reduced because of the increasing of sludge volume；Conversely,
When soil active force hour, cutterhead is pushed ahead relative to fuselage, and the mud discharging mouth between cutterhead and blade row reduces, because of the minimizing of sludge volume
And so that head-on soil pressure is raised, mechanically drive floating cutter head to automatically adjust the opening and closing amount of mud discharging mouth by oil cylinder, realize driving
When the automatically controlling of earth pressure balance.
Brief description
Fig. 1 is this utility model structural representation；
In figure：1- main stand, 2- pipe jacking tunnelling machine, 3- cutterhead oil cylinder, 4- rotary shaft, 5- cutterhead, 6- blade row, 7- spoil disposal

Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of this utility model protection.
Embodiment：
Refer to Fig. 1, a kind of slurry-water balance type pipe jacking tunnelling machine, including main stand 1, described main stand 1 is internal to pacify
Equipped with pipe jacking tunnelling machine 2, described pipe jacking tunnelling machine 2 is made up of cutterhead oil cylinder 3, rotary shaft 4, cutterhead 5 and blade row 6, described cutterhead 5
Positioned at main stand 1 side, described cutterhead oil cylinder 3 is located inside main stand 1, and described rotary shaft 4 passes through main stand 1, and one
End is located in described cutterhead oil cylinder 3, is located at outside main stand 1 near cutterhead 5 one end, and installed above has blade row 6, described knife
It is provided with a mud discharging mouth 7 above disk 5, described mud discharging mouth 7 is provided with controlled valve 8, described main stand 1 and pipe jacking tunnelling machine
