w beam guardrail design in china character

w beam guardrail design in china refers to three or more consecutive circular curves that are less than or equal to the minimum radius values listed in Table A, and the distance between the circular curves listed in Table A is less than the minimum distance between the circular curves listed in Table A.

or there are two or more turning curves whose radius is less than or equal to the minimum radius value of the circular curve listed in Table B, and from the end of one turning curve to the starting point of the next return curve.

In the normal operation of the highway, the guardrail can be easily inserted into the pre-arranged Jack at the opening by using the plug-out steel column, which can play the role of isolation and protection. At the same time,w beam guardrail design in china echoes the guardrail belt on the outer side of the highway, is uniform and beautiful.

Construction scheme construction sequence: construction sequence of entry column waveform guardrail: fixed point, release line, pile driving, pile adjustment, line installation, adjustment linear data, delivery acceptance construction scheme.
