Triple Tube Conventional Core Barrel

 

Triple Tube Conventional Core Barrels
 

Roschen Triple Tube Core Barrels are designed to maximize core recovery in site investigation and core exploratory drilling programs.
 

With these Core Barrels it is possible to obtain near 100% volumetric core recovery in the most undisturbed condition possible using rotary core drilling equipment. They have been used for exploration of dam, bridge and building sites as well as the development of mineral resources.
 

Triple Tube Core Barrels are normally supplied with stainless steel split inner tubes. Clear plastic tubing is available in NMLC size.
 

The plastic tubing is used when retaining the core exactly as it is recovered from the hole is desired. The core is left in the tube and the ends are sealed.
 

Visual examination is possible through the tubing on site or at the laboratory. The outer tubes are hard faced at each end to reduce wear and act as a stabilizer.

Triple Tube Conventional Core Barrel Set Up Instructions
 

· Unscrew the water end from the outer tube.

· Withdraw the water end and the holding tube assembly from outer tube.

· Remove the set screw from the bearing housing and insert the grease nipple.

· Apply grease.

· Remove grease nipple and replace the set screw.

· Dismantle the rest of the barrel and reassemble ensuring that all the threads are tight.

· Loose threads can result in water leaking through the inner tube and washing the core.

· It is generally not necessary to disassemble the bearing housing unless the barrel has been

stored for some time, in which case the bearings should be checked to ensure that they are fully greased.

· Check the distance between the core lifter adaptor case and the inner shoulder of the Bit.

· For medium to hard formations this clearance should be about 1.5m.

· For soft and friable formations this distance should be reduced to about 1.0m to prevent water from washing the core away.

· There should always be some clearance to prevent the core lifter adaptor case from rubbing on the Bit and allow cuttings to be washed from the inside gauge of the Bit.

· This clearance is adjusted with the spacer washers that are located between the bearing housing and the holding tube.
