京杭运河航道新型护岸造型技术

New revetment molding technology for Beijing-Hangzhou Canal Channel

为解决京杭运河传统护岸造型单一和结构不稳定的问题,结合京杭运河某航道整治工程,在混凝土重力式护岸结构的护面应用造型模板和劈离砌块两种新型材料。通过对两种护岸造型的应用研究,归纳总结其主要施工要点,并对比分析两种护岸造型的外观效果、经济效益,发现两者均能很好地展示造型效果,与运河文化相得益彰。而造型模板观感更优、单次造价高,但造型模板可循环利用,长远角度更经济;而劈离砌块更环保、经济。两种新型护岸造型在沿江沿河的城市河道整治、人文景观设计等领域均有较大的推广前景。

To solve the problems, including single molding and unstable structure, of the traditional revetment of the Beijing-Hangzhou Canal, this paper focuses on a channel regulation project on the Beijing-Hangzhou Canal and applies two new materials, i.e.,molding templates and split blocks, to the armor of the concrete gravity revetment. By investigating the application of the two types of revetment molding, this paper summarizes their main construction points and comparatively analyzes their exterior effects and economic benefits. The results show that the two types of revetment molding both display the molding effect well and share a mutually reinforcing relationship with the canal culture. Specifically, molding templates have a better appearance and higher cost per use. Nevertheless, it can be recycled and is thus more economical in the long term. In contrast, split blocks are more environmentally friendly and economical. The two new types of revetment molding both have broad promotion prospects in river regulation and human landscape design in cities along rivers.
