跨国道连续梁施工安全管理

Safety Management of Transnational Continuous Beam Construction

连续梁施工环境复杂,常遇到跨国道施工环境,其承台、门洞、连续梁模板等各环节的施工容易对原有公路的稳定运行造成影响。基于此,本文围绕新建京雄城际铁路,跨G112国道连续梁施工工程展开探讨,通过确定连续梁与跨越国道的线位关系,提出可行的连续梁跨路施工安全技术管理措施,包括桥梁主跨桩基、承台、墩身施工防护、公路范围外施工防护、安全警示标志布置等内容,以不影响原有公路车辆通行为基本前提,确保新建工程的整体质量。

The construction environment of continuous beams is complex,and the construction environment of cross-border roads is often encountered.The construction of various links such as the cap,the gate,and the continuous beam formwork are likely to affect the stable operation of the original highway.Based on this,this paper discusses the construction of a continuous beam on the new Gongxiong Intercity Railway across the G112 national highway.By determining the line position relationship between the continuous beam and the national highway,it proposes feasible technical management measures for the construction of continuous beams across the road,including bridge main Cross-piled foundations,caps,pier construction protection,construction protection outside the highway,layout of safety warning signs,etc.,so as not to affect the basic premise of the original highway vehicle traffic behavior,to ensure the overall quality of new construction projects.
