In the anchor cable stabilization works, anchor cable hole pore-forming characteristics can simplified summary be: the difficulty height, require sternly, and diameter is big, and the degree of depth is dark.Because soft stratum and slide plane pore-creating location is with a varied topography, often need pass through as boulder zone, zone, crack, severely-weathered district, major rupture band, solution cavity etc., very easily causes the phenomenon that the drilling tool drilling rod is blocked by stone in the hole.Because the bit freezing degree of depth is dark, factor such as can't look at straight, lock of tool drilling is extremely difficult to be got rid of, and especially the pore-forming position is had the engineering of high requirement, and lock of tool drilling is the main cause of duration of occasioning a delay.
According to long-term field condition experimental data as can be known, as strata condition in the hole just often, the revolution oil pressure in 4MPa, advances oil pressure 1MPa～4MPa (being subjected to combined influences such as hole depth, wind pressure of work, deslagging situation) substantially.When boring proceeded to broken formation, steering resistance increased, and when the revolution oil pressure was elevated to the high workload oil pressure of setting, main overflow valve was opened, and main skimmer circuit activates, and rotary motor stops operating, and is regarded as bit freezing this moment.As deal with improperly or the untimely just stuck easily useless hole of causing.And propelling pressure is too high or can not follow formation variations and respective change also is the main cause that causes stuck brill.
In the anchoring class rig of China, use the power source of single oil pump usually as anchoring drilling machine, for advancing oil cylinder and rotary fluid motor fuel feeding, use the anchoring drilling machine manufacturing cost of single oil pump lower simultaneously, technology is simple relatively.Because oil pressure changes with the stratum situation during rotary motor work, the execution unit of two different operating pressure can't directly collaborate or shunt, the hydraulic motor and the propelling oil cylinder that cause single pump to drive are wanted earlier before shunting through a damping unit, make oil pressure boost to main overflow valve overflow in off working state, the maximum working pressure that reaches the hydraulic system setting is supplied rotary motor, and the hydraulic oil after the overflow is connected in series to the forward operation valve again and drives the oil cylinder work that advances.Adopt this structure, motor and oil pump are worked under full load condition all the time, have not only strengthened energy consumption, and have shortened the application life of motor and oil pump, also increase because of the hydraulic oil heating causes interior the leakage easily, reduce operating efficiency.Boulder in the stratum, the irregular appearance in crack very easily cause lock of tool drilling in addition.
