Selection and excavation size of embedded parts

1. Generally, the diameter of the depression part of the high rod lamp is selected as the bottom diameter+ 100-150; if the bottom diameter of the lamp column is 500, the diameter of the depression part should be 600-650.

2. The height is one -tenth of the light rod, for example, the height of the depression part of the 25M light rod is 2.5m.

3. Digging depth is one -seventh of the high rod lamp rod. For 25 meters of lamp rods, the depth depth is about 3.5 meters (for a light rod less than 15 meters, the usual approach is usually one -eighth to nineths. one).

4. The excavation width is usually 3-4 times that of the standard built-in parts. For example, the excavation width of the built-in components with diameter 700 should be 2100 (depending on the weight and height setting of the light rod), usually 15 meters or less 2-3 times.

5. Generally, the concave part of more than 15 meters should be equipped with decorative flanges to avoid deformation of the concave part. Usually, the thickness of 6-8 cm is enough. The center has a 150-200 faucet that can pass the pipeline. The standard of high rod lamp flange is the same as the standard of the chassis.
