新型植绿生态混凝土挡墙设计及应用

Design and Application of New Green Planting Ecological Concrete Retaining Wall

近年来国内外掀起了生态混凝土研究热潮,主要有两方面,骨料配比和表面覆盖绿植,本次选择的新型植绿生态挡墙是混凝土表面覆盖绿植的应用方式之一。结合柏塘河治理工程开展了新型植绿生态混凝土挡墙设计,将重力式混凝土挡墙迎水面设置成台阶状,临水侧综合坡比1:0.5,花槽宽0.4 m,槽深0.3 m。通过对新型植绿生态混凝土挡墙与传统挡墙在结构安全、生态性、造价等多方面对比分析,得出了新型植绿生态混凝土挡墙具有传统挡墙不具备的生态性、景观性等优势,同时又保留了传统挡墙的抗冲能力、可靠性等优点,可供河道治理工程参考。

In recent years,there has been an upsurge of ecological concrete research at home and abroad,mainly in two aspects:aggregate ratio and surface covering green plants.The new green planting ecological retaining wall selected this time is one of the application methods of concrete surface covering green plants.Combined with the Baitang river treatment project,a new green planting ecological concrete retaining wall design is proposed.The upstream surface of the gravity concrete retaining wall is set into a step shape,the comprehensive slope ratio of the waterfront side is 1∶0.5,the width of the flower trough is 0.4m and the depth of the trough is 0.3m.Through the comparative analysis of the structural safety,ecology and cost between the new green planting ecological concrete retaining wall and the traditional retaining wall,it is concluded that the green planting ecological concrete retaining wall has the advantages of ecology and landscape that the traditional retaining wall does not have,while retaining the advantages of impact resistance and reliability of the traditional retaining wall,which can be used as a reference for river regulation engineering.
