MOLE DRAINAGE INVESTIGATION 1946-1947. DRAFT OF REPORT
Abstract
Mole drainage as used in agriculture consists of towing a specially constructed plow through the earth to make a hole three or four inches in diameter, parallel and approximately two to three feet below the ground surface with a narrow slot to the ground surface cut by the vertical blade of the plow. The purpose of this investigation is to develop a method of placing a strengthening liner on the walls of a mole hole and to determine the feasibility of adapting this type of drainage to airfield subgrades and shoulders, both as an aid during construction and as a method of installing permanent subsurface drainage systems.
