Upgrading the design of PVC lawn guardrail cross beam, the author uses the method of adding cross beam to compensate for the lack of wave beam thickness, improve the barrier capacity of PVC lawn fence, and avoid vehicle riding across PVC lawn guardrail during the collision process.
The self compacting concrete is poured into the column and longitudinal reinforcement is installed to improve the overall bending resistance of the column. On the basis of the original column, the diaphragm is added to make up for the insufficient thickness of the corrugated beam and enhance the tensile and shear performance of the PVC lawn guardrail.
从3 个方面对旧路波形梁pvc草坪护栏立柱进行安全性提升: 增加立柱的埋置深度，以保障pvc草坪护栏在碰撞过程中pvc草坪护栏立柱土基与立柱固结点的稳定性。
The safety of old wave beam PVC lawn guardrail column is improved from 3 aspects: increasing the embedment depth of the column to ensure the stability of the PVC lawn guardrail during the collision process, and the stability of PVC lawn guardrail column foundation and column.
The upgrading and transformation scheme maximizes the utilization of the wave beam PVC lawn guardrail in the 94 specification, which saves the cost. By increasing the reinforcement and increasing the buried depth, the PVC lawn guardrail meets the standard requirements.
By increasing the transmission way through the connection of the cross beam and the column, it is beneficial for the collision force to transfer to the multi span wave beam and reduce the force concentration of the wave Liang Lizhu.
