It includes and the hydraulic device of tunneling direction propulsive force is provided.
Wherein, the push-bench in the present invention, shield machine can use existing principle of propeller and shell, cutterhead, cutter, liquid
Press jack, casting structure, cutterhead driving device, stirring structure, error-correction structure, dynamic structure, hydraulic station, shield body and shield tail close
Based on the existing apparatus such as envelope.
Slurry transportation 51 and casting stir can be realized by screw conveying structure, more specifically, stirring structure 7 can be with
Including stirring rod, water inlet pipe, drainpipe and Grouting Pipe etc., the soil slag for getting off to knife disc tool cutting is stirred.Liquid
Pressure station 10 can be used for generating required hydraulic when push pipe and shield operation.
Pipe jacking construction method is used in engineering early period, starting well can be saved and excavate workload, accelerate construction speed, and energy
Save construction cost.When tunnel, build needs to turn or when unsuitable jacking construction, then can be converted shield-tunneling construction.Shield
Driving speed of constructing is fast, and curve may be implemented, adaptable, is suitble to construct under different geological conditions.
When construction starts, push pipe shield all-in-one machine is now hung in into starting well, luggage of going forward side by side is matched.Then according to jacking construction side
Method is tunneled forward by the front knife disc tool of propelling hydraulic cylinder driving push pipe shield all-in-one machine.
In the construction incipient stage, tunneled using pipe jacking construction method.In starting well, it will first be pushed up by propelling hydraulic cylinder
Pipe shield all-in-one machine promotes soil layer, and hydraulic cylinder jack is placed in the pithead position of starting well, and subsequent hydraulic cylinder jack retracts, puts
Enter a length of tubing, propelling hydraulic cylinder, which pushes pipeline, tunnels push-bench continuation forward, until being put into next length of tubing.So circulation
Back and forth, propelling hydraulic cylinder, which pushes pipeline push pipe, makes push pipe shield all-in-one machine constantly advance.When push pipe shield all-in-one machine Excavation Length
When reaching a tube coupling length or when reaching the critical distance of push pipe operation, then it is changed to shield operation.
In order to reserve enough spaces to shield-tunneling construction, first have to carry out reaming construction to the tunnel that push pipe generates.First
It is exactly that the lock piston rod of tight hydraulic cylinder of reaming cutterhead is first allowed to move out, drives hook to extrapolate by front rod and back link
Movement, hook is when closing up, and the interior exterior feature of several hooks is combined into a full circle, on the shoulder for hanging over the disc slide rod of broad,
The cutterhead for lockking broad securely, does not allow it to glide, and bears the axial reaming pull of cutterhead by several hooks, and promotes
Hydraulic cylinder is not subjected to reaming pull, realizes tunnel reaming in knife disc tool rotation.When linking up with opening, several hooks are simultaneously
It is detached from the shoulder of disc slide rod, cutterhead is in outside unfolded state, and cutterhead can come downwards to cutterhead under the action of propelling hydraulic cylinder
Lower end, the shoulder for touching disc slide rod lower end stop, and the axial force of cutterhead are born by the shoulder, propelling hydraulic cylinder does not stress.
Thus achievable driving reaming.
The section of jurisdiction used when shield operation is transported out of paved before good pipeline.At this point, according to construction needs, two
The transfer point of kind operational method adds a crossover sub.When shield operation starts, the propulsion cylinder of shield machine, which is withstood on, have been laid
Tube wall on, ensure that shield machine has enough counter-forces that can travel forward in this way.
Construction method later, as common shield method: shield head pushes ahead a distance, by pipe sheet assembling
Machine grasping pipe piece splices in tunnel.Then, the propelling hydraulic cylinder of shield machine, which is withstood on the section of jurisdiction newly spread, continues to tunnel forward, directly
To received well is reached, shield machine dismantling is hung out by worker.
Wherein, broad is used to expand tunnel diameter when push pipe operation becomes shield operation, is shield machine assembly pipe
Piece, pipe tail seal slot milling；Jacking uses the jack of more large-tonnages, and jack stroke is conventional top away from very heavy
It pushes power to be provided by oil pump, jack rear end sleeper and potential dividing ring are by counter-force stepless action in active well, front end jacking partial pressure
Ring, top iron will push up power and reaches tube coupling, and potential dividing ring production has enough rigidity, no deformation opposed flattened with pipe end face contact；Shield
Structure promotes the central part for being located at shield machine, is provided with the circular hole of installation propulsion cylinder thereon, is used to provide shield machine forward when shield
Driving power.
The above examples only illustrate the technical idea of the present invention, and this does not limit the scope of protection of the present invention, all
According to the technical idea provided by the invention, any changes made on the basis of the technical scheme each falls within the scope of the present invention
Within the technology that is not directed to of the present invention can be realized by the prior art.
