General feeling? Coil laying scheme
First of all, a groove should be cut on the road with a road cutter to bury the coil. Cut 45 degrees at four corners to prevent sharp corners from damaging the coil cable. The width of the notch is usually 4 to 8 mm and the depth is 30 to 50 mm. At the same time, cut a groove for the coil lead to the side of the road. However, it should be noted that the cutting groove must be clean and free of water or other liquids. When winding the coil, the coil must be straightened, but not too tight and close to the bottom of the slot. After winding the coil, the twisted output lead is led out through the lead-out slot.
Secondly, in the winding process of the coil, the inductance value of the grounding circuit should be actually tested by an inductance tester to ensure that the inductance value of the coil is between 100 uh-300 uh. Otherwise, the number of turns of the coil should be adjusted.
Three, after the coil is buried, in order to strengthen the protection, a circle of nylon rope can be wound around the coil. Finally, seal the groove with asphalt or soft resin.
If beauty is needed, you can use the coiled material with the thickness of 1.5 or 2.0 to cut the groove when paving the first pavement. Now go up to the second floor. That's effective and beautiful.
