跨巷挑顶风桥施工工艺及支护参数

Construction Technology and Supporting Parameters of Overhead Wind Bridge Crossing Roadway

为了提高风桥施工效率,减小施工对生产、通风系统的影响,结合23091措施巷跨2103巷风桥围岩地质情况,改进风桥施工工艺,合理设计风桥段支护参数,提高了施工效率,降低了风桥施工对生产和通风系统的影响。

In order to improve the efficiency of wind bridge construction and reduce the influence of construction on production and ventilation system,combined with the geological condition of surrounding rock of wind bridge across 2103 lane of 23091 measure roadway,the construction technology of wind bridge was improved,the supporting parameters of wind bridge section were designed rationally,the construction efficiency was improved,and the influence of wind bridge construction on production and ventilation system was reduced.
