Definitions

  • An excavator is provided with a box type casing including a pair of rotary cutters mounted on the bottom portion of the casing; blades provided at the outer periphery of the cutters provide excavating action with soil so excavated being discharged through a discharging tube having a sucking port around the retary cutters; further provision being made for slide cutters on the periphery of the casing. in operation the inter action of the rotary cutters provides discrete and alternate ditch bores whereafter the areas between the ditch bores are excavated to form a ditch of desired length and width.
  • the present invention relates to a rotary cutter type excavator, and more particularly to such an excavator wherein rotary cutters rotatable in opposite directions at the same speed are provided at the tip ends of a box type casing having its bottom side opened and so constructed that excavated soil is discharged on the ground with muddy water, and to an excavation method using such an excavating a rectangular, deep ditch or bore with high efficiency and stability.

  • the stabilizing liquid functions effectively to stabilize the ditch walls.
  • the second feature of the present invention is a construction in which an excavator mechanism with rotary cutters and a soil discharging mechanism for discharging excavated soil including muddy water by means of fluid carrier system are completely separated and independent to fully accomplish the first object of the present invention and to double the excavating capability.
  • the third feature of the present invention is that the excavation mechanism employs a rotary cutting mechanism in which a pair of rotary cutters are rotated in opposite directions, thereby excavating torques are balanced and deflection of the excavator is eliminated and excavation accuracy is increased, permitting stable, noiseless and vibration-free excavation.
  • the soil discharging mechanism is characterized in that an upward nozzle is provided just below the opening of the soil discharging tube formed in bell mouth shape, high speed jet from the nozzle to transport the mudy water including the excavated soil to an area in the opening of the soil discharging tube where it canbe sucked, and in that by the addition of the energy of the jet the suckable area of the soil discharging mechanism may be expanded to provide a sufficiently large soil discharging capability.
  • the other feather is that the penetration force of the excavator (especially frictional resistance and excavating force) is reduced by the use of slide cutter, and excavation of the ditch is effected such that a rectangular ditch having a geometry substantially equal to the lon-v are how we should" efficiently excavate the ground of different types of soil, how we should discharge the excavated soil on the ground rapidly and how should maintain the stability of the excavated ditch until the drive of the concrete.
  • One of the solutions is a muddy water excavation method using ground stabilizing solution such as bentnite solution.
