4.Either motor or diesel engine can be used for power supply to ensure high adaptability.
5.It is the first multi-purpose portable full-hydraulic drilling rig for engineering survey in the industry.
Hanfa operation method
Hanfa operation method is an engineering-geological drilling operation method developed by our company based on thin wall drilling rig with respect to characteristics of engineering reconnoitring, including the full-borehole wireline coring process and the not-lifting-the-drill-rod SPT casing drilling process.
Full-borehole thin-wall wireline coring process
* Reducing times of making a trip-Increasing the net drilling time and saving the energy consumption
* Declining the damage to borehole walls - Avoiding the damage to borehole walls caused by making repeated trips
* Increasing the coring recovery rate---A high coring recovery rate of shattering and unconsolidated formations
Not-lifting-the-drill-rod SPT casing drilling process
* Increase of efficiency-Not-lifting-the-drill-rod SPT test
* Enhancing safety in the borehole--Effectively avoiding the borehole wall from collapsing or chipping
* Increase of experimental accuracy-Avoiding the test rod from touching with borehole wall and having a high test progress
