<p>PURPOSE:To simplify the magnetic body burying work by digging a groove as a magnetic body burying line on a fairway and burying a connected magnetic body, where magnetic bodies are stored in a band-shaped bag body made of anti-corrosion fibers, in this groove. CONSTITUTION:Rectangular parallelepiped-shaped permanent magnets 4 having prescribed dimensions are used as magnetic bodies, and a connected magnetic band where magnetic bodies 4 are placed in a polyethylene band-shaped bag body 3 at prescribed intervals is so constituted that a sensor mounted on a cart can surely detect the magnetism. At first, the layout of a magnetic body line 1 is set in consideration of the running range of the cart while avoiding obstacles, electric wirings, drain pipes, etc., of the fairway. After the start point of the line is determined in the fairway, a groove 6 having prescribed dimensions is digged on the line by a lead cutter, and the connected magnetic body 7 is so buried that the N pole is placed on the ground surface side. After the connected magnetic body 7 is completely set in the groove 6, digged-out soil is returned, and cut-out turf 5 is buried back to completely cover the trace of burying of the connected magnetic body 7.</p> |
