Large-section open cut arch-shaped tunnel construction method
The invention relates to a tunnel construction method, in particular to a large-section open cut arch-shaped tunnel construction method. The large-section open cut arch-shaped tunnel construction method comprises the following steps that a steel reinforcement trolley is utilized to bind steel reinforcements, so that an arch-shaped steel reinforcement cage is formed; an external formwork trolley ismoved to the outer side of the arch-shaped steel reinforcement cage, and the steel reinforcement trolley is separated from the arch-shaped steel reinforcement cage; the steel reinforcement trolley ismoved out of the inner side region of the arch-shaped steel reinforcement cage; an internal formwork trolley is moved to the inner side of the arch-shaped steel reinforcement cage, and stabilizing devices are separated from the arch-shaped steel reinforcement cage; and the internal formwork trolley and the external formwork trolley conduct formwork closing construction, and a tunnel body structure in the corresponding region is formed. According to the large-section open cut arch-shaped tunnel construction method, the steel reinforcement trolley is utilized to bind the tunnel structure steelreinforcements, the binding operation of the arch-shaped steel reinforcement cage in the next zone of a tunnel, the pouring operation of concrete in the previous zone of the tunnel and the forming construction of the tunnel body structure can be simultaneously conducted, and therefore the construction progress is greatly quickened, the construction period is shortened, and the time cost of construction, the labor cost of construction and the total construction cost are reduced.
本发明涉及一种隧道施工方法，特别是一种大断面明挖拱形隧道施工方法，包含以下步骤：利用钢筋台车绑扎钢筋，形成拱形钢筋笼；将外模台车移动至拱形钢筋笼外侧，钢筋台车与拱形钢筋笼相脱离；将钢筋台车移出拱形钢筋笼内侧区域；将内模台车移动至拱形钢筋笼内侧，将稳定装置与拱形钢筋笼相脱离；内模台车和外模台车进行关模施工，形成对应区域的隧道主体结构。本发明的一种大断面明挖拱形隧道施工方法，利用钢筋台车来绑扎隧道结构钢筋，使得隧道下一区段绑扎拱形钢筋笼与上一区段浇筑混凝土，成型隧道主体结构施工可以同时进行，从而大大加快施工进度，缩短了施工工期，降低了施工的时间成本、人工成本及总施工成本。
