Existing river-crossing bridge and newly-built dike connecting structure and construction method thereof
The invention discloses an existing river-crossing bridge and newly-built dike connecting structure and a construction method thereof. The existing river-crossing bridge and newly-built dike connecting structure comprises an existing road, a connecting structure section and an existing river-crossing bridge, wherein the connection structure section comprises a sand gravel roadbed layer, a graded broken stone base layer is laid on the sand gravel roadbed layer, and a cement concrete pavement layer is poured on the graded broken stone base layer; the cement concrete pavement layer is composed of a slope starting section, a straight section and a slope descending section, a starting point of the slope starting section is connected with an existing river-crossing bridge, and an end point of the slope descending section is connected with an existing road; and retaining walls are further arranged on the two sides of the connecting structure section. Compared with the prior art, an existing river-crossing bridge for reconstructing water blocking is prevented from being dismantled, and engineering investment is reduced; a roadbed layer is filled with sand gravel excavated from a river channel so that investment is saved; the structure is simple, construction is convenient, materials are easy to obtain, manufacturing cost is low, and road passing requirements are met.
本发明为一种现有跨河桥梁与新建堤防衔接结构及其施工方法，包括现有道路、衔接结构段及现有跨河桥梁；所述衔接结构段包括砂砾石料路基层，在所述砂砾石料路基层上铺设级配碎石基层，在所述级配碎石基层上浇筑水泥混凝土路面层；水泥混凝土路面层由起坡段、平直段及降坡段构成，所述起坡段的起点与现有跨河桥梁相连接，所述降坡段的终点与现有道路相连接；在所述衔接结构段的两侧还设置有挡墙。与现有技术相比较，本发明避免拆除重建阻水的现有跨河桥梁，降低工程投资；采用河道开挖的砂砾石料填筑路基层，节省投资；结构简单，施工方便，材料易得，造价低廉，满足道路通行要求。
