When frictional resistance, pressure-raising oil cylinder is primarily subjected to the gravity from section of jurisdiction, drives section of jurisdiction slow by the decompression of oil cylinder rodless cavity
Slow uniform descent.When section of jurisdiction weight is less than the frictional resistance of the borehole wall, the pressurization of pressure-raising cylinder rod chamber, rodless cavity needs to keep at this time
It is centainly pressed, ensures that section of jurisdiction smoothly sinks under collective effect.It can discern whether to adopt by detection oil cylinder working-pressure during sinking
Antifriction processing is carried out with the mode of wall thickness slip casting, to ensure that pit shaft can smoothly sink.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
