Construction process and main points of highway sign post

The construction process and main points of highway signposts often appear in the construction of highway signposts. The installation angle and foundation must be consistent, especially the highway signposts with double columns and gate frames are prominent. A slight deviation in the center will lead to serious consequences such as the inability to install the door frame sign beam and the partial differentiation of the two-post installation sign point.

　　For these key measures that affect the overall quality, we should deal with: the center of gravity of the two-column highway sign post controlled at the two basic centerlines, especially the two base heights are inconsistent. Use a vertical cross ruler to ensure that the centerline coincidence accuracy deviation The foundation should not exceed 2mm; the center of gravity for the production of road sign poles on the door frame foundation should be placed on the control central axis from the base, and the door frame beams should be accurately measured for actual size data. Based on the data to determine the basic distance, you must sign based on the control of the distance deviation of less than 5mm, and the two basic control center deviations of 4mm; the contract is in accordance with the construction drawings and installation requirements. Install road traffic sign posts at right angles to the traffic flow. On curved roads, determine the direction of traffic flow from the perspective of traffic signals. The cantilever and door frame signs are tilted 2 degrees along the vertical axis. Highway signposts on the side of the road. The price of the signpost from the edge of the roadside must not be less than 250mm.
