METHOD AND EQUIPMENT FOR MOVING SILT AND WATER FROM AGRICULTURAL RESERVOIR TO PADDY FIELD

摘要

PROBLEM TO BE SOLVED: To provide an equipment for transporting excavated mud very quickly, efficiently and economically by fluidizing silt in an agricultural reservoir with high pressure jet water and mixing with water and then removing water with a pump. SOLUTION: When silt A is deposited in an agricultural reservoir, amount of water storage decreases and a water shortage occurs, then this silt A is fluidized in water by jetting a high pressure water from jetting pipe 1 having many small holes within an area surrounded by a curtain. This suspended water is sucked and removed by a pump 10, water is flowed to paddy fields, and silt A is dredged by an equipment placed on a raft guided by a guide rope 8 tensioned above a water level in a freely rising and descending manner thereby dredging the whole of silt A and fully utilizing water.
