VAN RUTH® GROUTING AND WATER CONTROL PACKER (GWC)

WATER CONTROL PACKER

The VAN RUTH® GROUTING AND WATER CONTROL PACKER (GWC) is designed for use mainly in underground drill holes yet it may also be used at the surface. The GWC is designed for grouting or controlled dewatering. The packer can be locked in the drill hole by hand or by utilizing the water pressure in the drill hole. Large GWC sizes can also be used as stem pipes or drill collars for drilling smaller size holes, for example the 76GWC packer can be used as a collar pipe for drilling 46mm holes.

The GWC has a standard BSP thread and is assembled onto a length or lengths of standard BSP water pipe and inserted into the drill hole to the required depth, the last length at the face will have an open valve (to alleviate back pressure while inserting). Pulling back on the pipe or closing the valve at the face, if pressure is present, will lock the packer in place. This packer needs pressure in the hole or tension from the face to maintain a tight seal. In dewatering or lower pressure situations, a grouting safety bracket is secured to the face to ensure tension is maintained.

Packers are available for all diamond drill, long hole, some large drill steel sizes and rotary percussion holes in a range of from 32mm to 152mm.

OPTIONAL:
GWC BL - Blanked off for sealing hole
GWC HDTY - Heavy duty solid urethane packing segment (more force will be required to set this packer and may need machinery to ensure proper sealing).

Construction: Smaller sizes are drillable aluminium and rubber - Please check with VAN RUTH staff for confirmation. Larger sizes are steel and rubber, again please check with VAN RUTH staff for confirmation.
