ICE CONSTRUCTION-PROTOTYPE SUBMERSIBLE ELECTRIC PUMP AND EXTENSION TUBE
Sea ice has been used extensively in polar regions for roads, runways, camp sites and other operational purposes. It has been found, through field experiments, that free flooding ice at subfreezing temperatures is an effective method of improving the surface and load bearing capacity of natural ice...
