SEDIMENT SAND REMOVING EQUIPMENT

摘要

PURPOSE:To fluidize off deposited fine sand, volcanic ash, etc., on water channel or side ditch of road by providing a rocking jet nozzle. CONSTITUTION:A water tube 7 connected with a pump equipment is set along the inside or outside of water channel or side ditch 2 and many rocking jet nozzles 15 are set on the way of the tube 7. Pressure water 10 from a pump is sent from the downstream side to the upstream side and discharged at the end of the tube 7 and also jetted from the nozzle 15. Deposited sand 4 on the bottom of the side ditch 2 is fluidized by jet water 16 from the nozzle 15 and flowed down toward the downstream side of the side ditch 2 by effluent water 12 from the end of the tube 7.
