casing adapter of rotary drilling rig casing tube pipe
THE CASING ADAPTER
The driver sinking casing relies on the rotary drilling rig itself to provide torque and pressure, and the pipe swinging device is connected with the power head on the upper part and driven with the flower tube on the lower part; Drive the flower tube to connect the casing. During the use, the driver will not interfere with the drilling tools and drill pipes, and the combined operation of sinking casing and fishing rock and soil can be realized. The advantages of the driver are simple equipment structure, low procurement cost, no additional hydraulic station or other large equipment is required for auxiliary construction, and it can effectively improve the construction efficiency and reduce the construction cost in the construction of short piles and small diameter piles. However, because the driver is limited by the torque and pressure of the drilling rig, the problem of insufficient torque and pressure will be encountered in the construction of deeper piles and large-diameter piles, and the verticality of the pile is general.
