摘要： A guardrail safety system includes a guardrail beam operable to contain and redirect an errant vehicle to prevent the vehicle from leaving a roadway. At least a portion of the guardrail beam includes a thrie beam. A support post is coupled to the guardrail beam and includes a lower portion, a mid portion, and an upper portion. The lower portion is installed below grade adjacent the roadway. The mid portion lies substantially adjacent the grade and is weakened about a first axis without being substantially weakened about a second axis that is generally perpendicular to the first axis. An upper portion is releasably coupled to the guardrail beam such that the upper portion is uncoupled from the guardrail beam when the mid portion yields about the first axis.

摘要： The present invention provides a system, method and apparatus for supporting guardrail posts. The system includes a foundation tube, a guardrail post partially disposed within the foundation tube, and a spacer disposed between the guardrail post and the foundation tube. The spacer has overall dimensions of approximately (a) a first dimension that is smaller than a first interior dimension of the foundation tube, (b) a second dimension that is equal to or less than a second interior dimension of the foundation tube less an exterior dimension of the guardrail post and (c) a third dimension greater than or equal to one half of the first dimension.

摘要： In accordance with a particular embodiment of the present invention, a guardrail safety system includes a guardrail beam having a length-of-need (LON) portion spanning between two terminal portions. The guardrail safety system also includes a plurality of guardrail support posts in spaced apart relation to one another. At least a portion of the plurality of support posts include a lower portion for installing below grade adjacent the roadway, a mid portion that lies substantially adjacent the grade, and an upper portion releasably coupled to the LON portion of the guardrail beam. The mid portion includes a weakened section operable to weaken the support post about a first axis without substantially changing the behavior of the support post about a second axis that is generally perpendicular to the first axis.

摘要： A heavy duty ground retractable automobile barrier for a railroad crossing. Concrete bunkers are placed at each side of a roadway. An upstanding concrete-filled steel pipe fixed in each bunker has a sleeve for rotational and axial movement. Shock absorbers are mounted on each sleeve. A net extends across the road and is attached to the opposite ends of the shock absorbers. Collision of an automobile with the net creates tensile forces in the net. The shock absorbers expand while rotating about the pipe's axis in response to tensile forces from the net that meet or exceed a minimum threshold. Forces from the net pass through the axis of the steel pipe. The net is stored in a pit transverse the roadway parallel to the railroad tracks and is raised and lowered as appropriate. The net includes a cable that extends across the road in a wave pattern, having peaks, valleys and midpoints, wherein tangents of the wave midpoints are at least 90 degrees from tangents of the peaks and valleys.
