装配式生态挡墙施工技术研究

Analysis of Construction Technology for Prefabricated Ecological Retaining Wall

近年来,随着环保意识的提高,生态挡墙逐渐成为城市规划、景观建筑的主流选择,相较于传统混凝土挡墙,生态挡墙的生态性和美观性在城市绿化、垂直绿化、建筑节能等方面都得到了广泛的应用。结合重庆两江新区人高路二期的挡墙工程,介绍了一种预制装配式生态挡墙,由现浇基础十预制装配式PC构件十现浇肋柱十现浇压顶梁组成,可在大部分情况下替代传统挡墙,具备施工方便快捷、造价低、占地面积小等优点。其中PC构件的植生板能为绿色景观植物提供良好的生长环境,在迅速恢复原始生态的同时打造立体生态景观,符合国家绿色发展政策。

In recent years,with the increasing awareness of environmental protection,ecological retaining walls have gradually become the mainstream choice for urban planning and landscape architecture.Compared with traditional concrete retaining walls,the ecological and aesthetic properties of ecological retaining walls have been widely applied in urban greening,vertical greening,building energy conservation,and other aspects.In combination with the retaining wall project of Rengao Road Phase II in Liangjiang New Area,Chongqing,this article introduces a prefabricated ecological retaining wall,which is composed of cast-in-place foundation,prefabricated PC components,cast-in-place rib columns,and cast-in-place pressure top beams.It can replace traditional retaining walls in most cases,and has the advantages of convenient and fast construction,low cost,and small footprint.The planting board of PC components can provide a good growth environment for green landscape plants,while quickly restoring the original ecology and creating a three-dimensional ecological landscape,which well responds to the national green road policy.
