摘要
介绍涵洞快速施工方法——预制装配式涵洞施工法。研究涵洞构件搭接部位的受力特性,对涵洞台帽和涵台连接处、涵台嵌入基础部分2个薄弱面进行强度分析。建议台帽和涵台结合面采用C25混凝土或M30水泥砂浆粘结,涵台嵌入基础顶面深度不小于5cm。
In order to promote the rapid construction technique of culvert,prefabricated culvert con-struction method,a rapid culvert construction method,is introduced.In this paper,the mechanical properties at the bonding area of the components are mainly studied,while the strength of two weak surfaces is also analyzed.The results suggest that the bonding surface of abutment cap and side wall of culvert should be bonded with C25 concrete or M30 cement mortar,and the depth that the side wall embedded into the base top surface,should not below 5 cm.
