肯尼亚公路涵洞常用施工方法及创新技术

Common Construction Methods and Innovative Technologies of Highway Culverts in Kenya

近年来,随着肯尼亚经济的发展,肯尼亚公路涵洞基本上都是以钢筋混凝土箱涵与圆管涵为主,简要介绍了箱涵及圆管涵常用施工方法,以及混凝土的配合比设计过程,并结合肯尼亚当地实际,在原有施工方法的基础上,创新采用橡胶气囊作为涵洞内膜,使用现浇混凝土的施工技术,减少了施工工序,缩短了施工时间,可供同行参考。

With the development of Kenyan economy in recent years,Kenyan highway culverts are basically reinforced concrete box culverts and circular pipe culverts.The common construction methods of box culverts and circular pipe culverts,and the design process of mix ratio of concrete are briefly introduced,combined with the local practical condition in Kenya,based on the original construction method,rubber airbags are innovatively used as the inner membrane of the culvert,the site construction technology of pouring concrete is adopted,which reduces the construction process,shortens the construction time and provides reference for road construction colleagues.
