Technical field
The utility model relates to a kind of pipe jacking tunnelling machine heads for being able to achieve overturning and correcting automatically, belong to excavation work Mechanical course
Technical field.
Background technique
Pipe jacking tunnelling machine is a kind of engineering machinery of not digging laying pipeline, solves and builds in piping laying construction to ground
The problems such as the destruction of object and the blocking of road traffic are built, are had many advantages, such as in terms of not removing, not influencing environment.China's push pipe driving
The application of machine engineering technology is started late, and by the development of many years, pipe-jacking technology has obtained Practical Project in large quantities in China and answered
With, and remain the growth of high speed.
The principle of construction by pipeline jacking method is development machine cutterhead by constantly squeezing cutting front soil layer, in working pit by means of
Jacking device top power overcomes the frictional force and frontal drag of pipeline and soil, and pipeline is headed into soil by the gradient of design, and will
The earthwork is transported.The completion of one section pipe heads into soil layer and then lower second section pipe continues jacking.
For development machine during subsurface jacking construction, cutterhead passes through continuous rotary cutting front soil layer, front soil layer
Have to cutterhead and applies a reaction.If strata division boundary line fluctuations along the line, when encountering hardpan or object, cutterhead
Increased suddenly by reaction force, the overturning opposite with cutterhead rotation direction may occur rapidly for development machine.
After development machine overturns, it will lead to construction and interrupt, the delay of push pipe progress.Due to development machine phreatic line with
Lower soil layer operation has ponding in cabin, and internal electrical installation can intake, such as distribution box, headlamp, motor.First is that
