摘要
为保障G72泉南高速公路行车安全,减少永新枢纽互通立交施工过程中对其的干扰,故提出搭设2跨宽15 m、净空大于5.5 m的墩梁式防护棚的方案。通过对防护棚的简算,验证了防护棚设计的安全、可靠。同时制定了防护棚的施工方案,并经实际验证,安全可行,为类似需提供防护的工程提供参考依据。
In order to ensure the traffic safety of G72Quannan Expressway and reduce the interference during the interchange construction of Yongxin Hub,this paper proposes to build two pier-girder protective sheds with a span of 15 m and a headroom greater than 5.5 m.Through the simple calculation of the protective shed,the safety and reliability of the protective shed design are verified.At the same time,the construction scheme of the protective shed is formulated,which is proved to be safe and feasible in practice,providing a reference for similar projects that need to provide protection.
