摘要
针对当前河道直立式硬质挡墙生态化改造技术研究方案,提出了安全性、生态性、景观性、可行性4个改造原则。结合现有改造技术优点,提出了锚固支承式和手动升降式城市河道直立挡墙改造技术、锚固模块式及自动升降式改造技术,其中锚固模块式结构更加简单,扩充了植物生长空间及所需基质容量,自动升降式的种植槽不仅可以随水位升降,还具有免浇灌、易维护的特点。在实际应用中,可根据挡墙的情况,进行组合选用,以期达到最佳改造效果。
According to the current research scheme of ecological reconstruction technology of river erect rigid retaining wall,four reconstruction principles of safety,ecology,landscape and feasibility were put forward.Combined with the advantages of existing reconstruction technology,anchoring support type and manual lifting type urban river erect retaining wall reconstruction technology,anchoring module type and automatic lifting type reconstruction technology were put forward,in which the structure of anchoring module was more simple.it expand the plant growth space and the required substrate capacity,and the automatic rising and falling planting trough can not only rise and fall with the water level,but also has the characteristics of no watering and easy maintenance.In practical application,the combination and selection can be carried out according to the situation of the retaining wall,in order to achieve the best transformation effect.
