Levee construction
专利汇可以提供Levee construction专利检索，专利查询，专利分析的服务。并且PURPOSE: To form the levee of ideal strength, by solidifying the crest face and the side face of an earth-filling section respectively with a keep plate for the crest face and a keep plate for the side face, after the earth-filling section is formed with cultivating ratchets.
CONSTITUTION: Earth on the paddy field surface is scraped with the respective cultivating ratchets 11 of the horizontal shaft section 12a of a rotary shaft 12, and the crest face side is filled with earth by means of the respective cultivating ratchets 11 of an inclined shaft section 12b to construct the earth-filled section Y1. After that, respective keep plates 13 are butted against the crest face and side face of the earth-filled section Y1 respectively from two directions, and the agricultural machine is towed by a tractor. After that, by the graded land surface section 13a of the respective keep plates 13, earth on the rugged sections of the earth-filled section Y1 is pushed out as much as possible in the direction of the traction, and at the same time, each surface of land is graded. Besides, the power of the agricultural machine is transmitted to the respective keep plates 13 via a combined rod 14 and a frame 15, and the respective pressed surface sections 13b of the earth-filled section Y1 are evenly solidified with elastic pressure.
