Description

TECHNICAL FIELD

[0001] The application relates to the technical field of sign pole structures, in particular to a ground cantilever type sign pole structure. BACKGROUND

[0002] Traffic sign poles are also called road sign poles, highway sign poles, and posts used on both sides of highways to indicate traffic routes. The traffic sign poles are formed by processing steel pipes and the surfaces are subjected to hot galvanizing treatment. The traffic sign poles are classified into single-cantilever type sign poles, double-cantilever type sign poles, double-column type sign poles, single-column type sign poles, hot-galvanizing sign poles and various posts. The traffic sign poles are widely used in expressways, urban highways and various roads. The inner edge of the column type sign pole should not intrude into the road construction limit, and the distance from the outer edge of the vehicle lane or the pedestrian lane or the soil road shoulder should be not less than 25 cm. The height of the lower edge of the traffic sign plate from the road surface is not less than 5500 mm for expressways, not less than 5000 mm for national roads and provincial roads. When the traffic sign plate is arranged on a city road with a large proportion of small vehicles, the height of the lower edge from the ground can be adjusted according to the actual situation, but should be not less than 120 cm.
