生态U形板桩在城镇中小河流综合整治中的应用

Application of Ecological U-shaped Sheet-pile in Comprehensive Governance of Small and Medium Urban Rivers

近年来,全国各地逐步开展中小河流综合整治工作,统筹水安全、水生态、水景观同步建设,但城镇中小河流综合整治往往由于现状基础较差、生态景观要求高、沿岸建筑多征地困难、地质条件差、资金不足、工期不足等原因而推行困难,进展缓慢。该文通过广州市某河涌整治实例,对生态砖护岸、浆砌石护岸和生态U形板桩护岸在安全可靠性、生态景观效果、经济性、可实施性等方面进行比选论证,得出生态U形板桩在城镇中小河流综合整治中更具优势的结论,可供类似工程借鉴。

In recent years,the comprehensive governance of small and medium urban rivers is being carried out all over the country,and it is stipulated that Water Safety,Water Ecology and Water Landscape should be constructed simultaneously.However,it is difficult and slow to carry out for many reasons,such as the poor foundation,high requirements for ecological landscape,many buildings along the banks,difficult land acquisition,poor geological conditions,lack of funds,insufficient construction period and so on.Based on the example of a river governance in Guangzhou,the paper compares three kinds of revetment,including Ecological-brick,masonry and Ecological U-shaped Sheet-pile,and comes to the conclusion that Ecological U-shaped Sheet-pile have more advantages through the comparison in safety and reliability,ecological landscape effect,economy,feasibility and other aspects.
