Description
Technical field
The utility model relates to the construction fields of girder formula TBM, particularly relate to a kind of girder formula TBM support boots adjustment control machine
Structure.
Background technique
TBM is at home and abroad widely used in long-distance hard rock constructing tunnel at present.It is quick-fried relative to traditional brill
Method construction, it is much higher using TBM construction efficiency, and the excavation and support in tunnel is assisted completing by TBM.
Girder formula TBM in the construction process, after the completion of each driving stroke, is needed by changing step for propelling cylinder
It resets, is ready work for the driving of next stroke.The work progress of girder formula TBM is broadly divided into three steps: driving, branch
It protects, change step.It wherein supporting and changes step and belongs to non-driving state, the length of time will influence whether the utilization rate of TBM, i.e. TBM
Construction efficiency.The time of supporting is affected by country rock situation, however changes step process speed then mainly by equipment itself institute
It determines.
Changing step is to reset propelling cylinder after the completion of each driving stroke, carries out standard for the driving of next stroke
Standby work.It completely changes step process and is divided into five steps: the first step, girder formula TBM rear support is stretched out, stretching ground；Second step,
Support boots recycling of the stretching on the wall of hole；Third step, support boots are moved along under the pulling force effect of propelling cylinder with saddletree, until pushing away
Oil inlet cylinder resets completely；4th step, support boots stretch out, and high pressure stretching is on the wall of hole；5th step, rear support recycling, until leaving
Ground.
Girder formula TBM change step during first, second and third, five steps, during changing step, the speed of speed completely by
The design parameter of girder formula TBM itself is determined that the influence of the factor of external environment is relatively small.But girder formula TBM changes step
The 4th step in the process, then will receive the influence of assembled steel arch-shelf.Under normal circumstances, assembled steel arch-shelf it
Between the spacing stayed, space needed for being just met for support boots.But in practice of construction, assembled steel arch-shelf spacing is had
Biggish error, or even can yet generate certain inclination.In this case, the stretching for supportting boots can be often less smooth,
Interference is generated with steel arch-shelf when i.e. support boots stretch out.Because it is larger to support boots quality itself, and is connected with propelling cylinder, so logical
External force is crossed to change support boots and the relative position of steel arch-shelf is highly difficult.
