lamp selected:

1, field Kan test, no obstructions around the lamp. There's some room for lifting installation ( Around the presence of high voltage cable, etc. ) 。

2, according to street lamp installation specification requirements set lamp roads, using three kinds of cloth lamp ( Cloth lamp unilateral, cross cloth lamp, bilateral symmetric cloth lamp) ； High light, and road width and cloth lamp way relationship; Lamp spacing, and high light and irradiation Angle relationships ( General is three times as high light or so) 。

basic prefabricated:

1, the determination of embedded parts size, according to provide data and actual installation I need light pole factory, light is high and embedded parts size relations in the following table:

2, digging holes, dimensions according to the foundation pit size, type battery set is buried at the same time; Specific see the foundation drawing for

3, prefabricated foundation and prefabricated foundation, concrete grade according to C20 to perform, at the same time to vibration compaction of foundation with vibration mechanism, to ensure the quality, when pouring concrete, pay attention not to the concrete casting on wire rod, lest affect installation speed. When threading pipe pressure, pressure, according to the drawing and make sure not to concrete injection tube. The nozzle position from the base plane distance is 250 mm. For underlying surface leveling, with the level test, to ensure accurate level four feet.
