采用波纹状管材料或者波纹状弧形板链接拼装而成的一种涵洞形式称之为波纹管涵洞。波纹管的受力特征表现明显,原因在于存在轴向波纹,减少荷载应力集中,特别适用于较差的地质区。钢波纹管涵洞造价低于钢筋混凝土结构,而且工时少,不用洒水养护,施工不受气温影响。本文将对高速公路中的大孔径钢波纹管涵洞施工技术进行研究,旨在为钢波纹管涵洞的施工范围、施工条件、施工要求提供借鉴。
The use of corrugated pipe material or corrugated curved plate assembled from a form of culvert called corrugated pipe culverts. Corrugated pipe force characteristics of the obvious performance, because there is the existence of axial ripple, reduce the load stress concentration, especially for the worse geological areas. Steel corrugated pipe culverts cost less than reinforced concrete structures, and less man-hours, no water conservation, construction from the impact of temperature. In this paper, the construction technology of large aperture steel corrugated pipe culvert in highway will be studied in order to provide reference for the construction scope, construction conditions and construction requirements of steel corrugated pipe culvert.
