摘　　要：目前,市政工程桥涵施工中采用较多的是碗扣满堂支架施工方法,具有施工简便、速度快、整体稳定性较好等特点。但随着市政工程施工进程的加快,施工中不间断交通、安全及高质量的要求,单纯的碗扣满堂支架施工方法已无法满足市政工程桥涵支架施工要求,而大管径钢管立柱施工方法恰好能满足交通复杂施工环境下桥涵支架的施工要求,且具有较好的效果。文章结合施工实践,本着安全高效的原则,进行了一系列的实践探索,采用钢管柱门洞式支架,进行预留门洞保持车辆安全通行,最终取得了令人满意的效果。At present,the bowl buckle full hall bracket construction method is widely used in the construction of municipal Bridges and culverts,which has the characteristics of simple construction,fast speed and good overall stability.However,with the acceleration of the construction process of municipal engineering,the requirements of uninterrupted trafic,safety and high quality in the construction,the simple bowl buckle full hall support construction method has been unable to meet the requirements of municipal engineering bridge and culvert support construction,while the construction method of large diameter steel pipe column can just meet the construction requirements of bridge and culvert support under the complex construction environment of traffic,and has a good effect.In this paper,combined with the construction practice,in line with the principle of safety and efficiency,a series of practical exploration,the use of steel pipe post door bracket,the door is reserved to keep the vehicle safe passage,and finally achieved satisfactory results.
