The Casagrande FD hydromills are designed by Casagrande to match today's demands of diaphragm wall construction. Whenever the challenge of diffi -cult soil condition, high productivity and shear accuracy are made in diaphragm walling, the Hydromills can cope.Versatility whether in hard or soft soils, a choice of cut-ters is available to match every condition and demands of different wall width scan be easily met, simply by changing the cutter wheels and the interchangeable guides. All models of the hydromills are designed to work on the prin-ciple of reverse circulation. Cutting chains are used enable the equipment to cut through hard strata, to guarantee the cut throughout the wall width and to provide better joints and excellent interlocking.PerformanceThe hydromills utilizes a wealth of engineer-ing expertise gained by Casagrande in many years of geotechnical available for the appli-cation of electronics to record depth, verticality and cutting force and to provide with instant information to control performance and maxi-mize on production. The all-round ruggedness of hydromills are complemented by attention to details. The suspension of the hose reels by automatic winches and the fi tting of a power-ful fl ushing pump to remove cuttings.
