BIM技术在超深超大竖井施工中的应用

Application of BIM Technology in Super Deep and Super Large Shaft Construction

关山隧道中超大断面超深通风竖井具有施工技术复杂、安全风险高、施工管理难度大等特点。根据超深超大竖井施工组织特点,针对性地应用BIM技术,实现了在狭小作业区域内施工场地的合理布置,特别是在场地布置、天轮平台系统合理布局中应用效果显著。通过应用BIM技术优化了竖井二衬及十字隔墙同步浇筑施工方案,在施工过程中实现了三维技术交底、工程机具的创新设计等,大大加快了现场施工进度,降低了施工成本,保障了现场施工安全及施工质量。这对于采用正井法开挖施工超大超深隧道通风竖井具有重要的借鉴意义。

The super large cross-section and super deep ventilation shaft in Guanshan Tunnel is characterized by complex construction technology,high safety risk and difficailt construction management.According to the construction organization characteristics of super deep and super large shaft,BIM technology is applied to realize the reasonable layout of construction site in the nairow operation area,especially in the site layout and the reasonable layout of the platform system.Through the application of BIM technology,the synchronous pouring construction scheme of shaft second lining and cross partition wall is optimized.In the construction process,the three-dimensional technical disclosure and innovative design of engineering machineiy are realized,which greatly speeds up the construction progress,reduces the construction cost,and ensures the construction safety and construction quality.It has an important referential significance for the construction of ventilation shaft of super large and super deep tunnel by the main shaft method.
