Functionally gradient crash barrier and construction method thereof
The invention discloses a functionally gradient crash barrier, and the crash barrier comprises a base, an energy dissipation layer and a UHPC panel, wherein the energy dissipation layer is arranged between the base and the UHPC panel. The invention further provides a construction method of the functionally gradient crash barrier. The construction method comprises the following steps: S1, prefabricating the reinforced concrete base, the UHPC panel and the energy dissipation layer, when the reinforced concrete base, the UHPC panel and the energy dissipation layer are prefabricated, pipelines forinstalling the energy dissipation connecting pieces are synchronously reserved; S2, installing the base on a bridge or a road; S3, installing an energy dissipation layer and a UHPC panel on the base,inserting the energy dissipation connecting pieces, and completing the construction of the functionally gradient crash barrier. The functionally gradient anti-collision guardrail has the advantages of being good in guidance quality, capable of reducing accident consequences, good in durability, low in manufacturing cost, short in construction period, easy and convenient to maintain and replace and the like, has a great use value and good economic benefits, and has wide application prospects.
本发明公开了一种功能梯度防撞护栏，包括基座、消能层和UHPC面板，所述消能层设于所述基座和UHPC面板之间。本发明还提供一种上述的功能梯度防撞护栏的施工方法，包括以下步骤：S1：预制钢筋混凝土基座、UHPC面板和消能层；预制钢筋混凝土基座、UHPC面板和消能层时同步预留安装消能连接件的管道；S2：将基座安装在桥梁或道路上；S3：在基座上安装消能层和UHPC面板，再插入消能连接件，即完成功能梯度防撞护栏的施工。本发明的采用功能梯度防撞护栏具有导向性好、减小事故后果、耐久性好、造价低、施工周期短、维修更换简便等优点，具有极大的使用价值和良好的经济效益，具有广阔的应用前景。
