目前我国城市地铁建设不断发展,浅埋暗挖法在城市地铁建设中不断得到应用,城市地铁隧道及大跨度暗挖车站,多为拱弧型断面,而且断面变化频繁。模板台车、钢模板在地铁隧道二衬施工中得到了广泛的应用并不断的发展、完善。由定型平面钢模板发展到定型弧型、翼型钢模板。但衬砌工程模板加工成本一次性投入较大,工程竣工后模板再次利用率不高。可调圆弧钢模板可根据不同弧型断面进行调试,也可用于直墙式衬砌。它可适用于多种断面,是一种多功能钢模板。
At present, the continuous development of urban subway construction in our country, the continuous excavation method has been applied in the construction of urban subway. The urban subway tunnel and long-span uncovered station are mostly arc-arch sections with frequent changes in sections. Template trolley, steel template in the subway tunnel lining construction has been widely used and continuous development and improvement. From the stereotypes of flat steel template development to the stereotypes arc, wing steel template. However, one-time investment in the processing cost of lining engineering templates is large, and once the project is completed, the utilization of the templates is not high. Adjustable arc steel template can be commissioned according to different arc sections, can also be used for straight wall lining. It can be applied to a variety of sections, is a multi-functional steel template.
