Large Canal Liner
The G&Z Canal Liner is available in both two- and four-track configurations, with self-moving options for maximum efficiency. It can even be converted in the future for use as a highway or airport paver, extending the value of your investment. Each machine is tailored to your project: jacking columns, crawler tracks, truss main frame, power unit, and conveyor widths are selected to match your maximum future canal periphery, target concrete or base/filter production rates, and the delivery system used to meter material to the Liner and your intended hauling truck.
​
To ensure material stays on the slopes, off the front of the Liner is included a liquification hopper positioned ahead of the slipform pan. Divided into compartments approximately 36 in. (1 m) wide, the hopper uses individual high-frequency poker vibrators to liquefy the concrete (or wet base/filter) and ensure uniform placement across the front of the Liner. Off the back of the Liner frame, a rear walkway with stairs provides safe access for checking lining thickness, finishing, and forming joints. Optional equipment includes:
​
-
Hydraulic joint cutter (“Guillotine”) – Vibrates and forms transverse contraction joints. The system automatically cycles and pauses the Liner during cutting and vibrating; hand finishing is required.
-
Keel bars – Integrated into the slipform pan for forming longitudinal contraction joints at specified locations.
-
PVC joint installation systems – Available for both preformed PVC transverse and longitudinal joint materials, ideal for high-production lining operations.
​
Drawing on decades of experience, G&Z has found that its concrete wiper conveyor system is the most flexible and efficient method for distributing concrete, base, or filter material into the Liner liquification hopper — especially on long slopes. These conveyors can be scaled to achieve production rates from 60 to 600 cy/h (45 to 470 m³/h). Output is typically limited only by:
​
-
The practical production of the concrete plant
-
Type and number of delivery trucks
-
Material transfer method used to meter concrete to the wiper conveyor
-
Joint forming and finishing operations
