Closed-cell foamed aluminum sandwich ultra-high-performance lightweight concrete road guardrail
The invention discloses a closed-cell foamed aluminum sandwich ultra-high-performance lightweight concrete road guardrail, belongs to the technical field of road guardrails, and aims to solve the problems of poor durability, large dead weight and low anti-collision deformation capability of a current concrete guardrail. Comprising a guardrail foundation and a plurality of guardrail walls, the guardrail foundation is in a long-strip plate shape, the guardrail walls are detachably connected with the guardrail foundation, and the guardrail walls are sequentially matched in an inserted mode in the length direction of the guardrail foundation; the guardrail wall body comprises a closed-cell foamed aluminum plate and a second lightweight concrete skin, the closed-cell foamed aluminum plate is vertically arranged, second reinforcing meshes parallel to the closed-cell foamed aluminum plate are arranged on the two sides of the closed-cell foamed aluminum plate, and the closed-cell foamed aluminum plate and the two second reinforcing meshes are poured into the second lightweight concrete skin. Vehicle impact is resisted through the second lightweight concrete skin, the closed-cell foamed aluminum plate is used for deforming and absorbing impact energy, the strength of a rigid guardrail is achieved, and the advantages of buffering and energy absorption of a flexible guardrail are achieved.
一种闭孔泡沫铝夹芯超高性能轻质混凝土公路护栏，属于公路护栏技术领域，本发明为了解决当前混凝土护栏耐久性差、自重大、防撞变形能力低的问题。包括护栏基础和若干护栏墙体，护栏基础呈长条板状，护栏墙体与护栏基础可拆卸连接，若干护栏墙体沿护栏基础的长度方向依次插接配合；护栏墙体包括闭孔泡沫铝板和第二轻质混凝土外皮，闭孔泡沫铝板竖向设置，闭孔泡沫铝板的两侧均设有与闭孔泡沫铝板平行的第二钢筋网片，第二轻质混凝土外皮将闭孔泡沫铝板和两个第二钢筋网片浇筑在内。本发明通过第二轻质混凝土外皮抵抗车辆撞击，闭孔泡沫铝板用于变形吸收冲击能量，既具有刚性护栏的强度，又具有柔性护栏的缓冲吸能的优点。
