System conversion construction method and system for open cut tunnel high-density lining steel bars
The invention provides a system conversion construction method for open-cut tunnel high-density lining steel bars. The system conversion construction method comprises the steps that S1, lining steel bars are bound on a steel bar trolley; s2, the type of an auxiliary support is judged according to the supporting force needed by the lining steel bars, and the lining steel bars are supported through the auxiliary support; the auxiliary support comprises a lateral supporting system and a lifting point system, the lateral supporting system is used for transversely supporting the two sides of the lining steel bar, and the lifting point system is used for vertically pulling the top of the lining steel bar; s3, the steel bar trolley moves to the next station, and the formwork trolley moves to the corresponding station of lining steel bars; s4, the auxiliary support is removed, and the self-weight load of the lining steel bars is converted to be borne by the formwork trolley; and S5, formwork erecting, concrete pouring and curing are conducted. The method is suitable for system conversion of open-cut tunnel high-density lining steel bars, the deformation amount of the high-density lining steel bars is guaranteed, movable factory type assembly line work of high-density lining steel bar tunnel lining is achieved, and the construction efficiency is improved.
本发明提供一种明挖隧道高密衬砌钢筋的体系转换施工方法，包括：S1、在钢筋台车上绑扎衬砌钢筋；S2、根据衬砌钢筋所需支撑力判断采用辅助支撑的类型，利用辅助支撑对衬砌钢筋进行支撑；辅助支撑包括侧向支撑系统和吊点系统，侧向支撑系统用于横向支撑衬砌钢筋的两侧，吊点系统用于竖向牵拉衬砌钢筋的顶部；S3、钢筋台车移动至下一工位，模板台车移动至衬砌钢筋对应工位；S4、撤除辅助支撑，将衬砌钢筋自重荷载转换由模板台车承担；S5、支模、浇筑混凝土并养护。本发明适用于明挖隧道高密衬砌钢筋的体系转换，保证高密衬砌钢筋的变形量，实现了高密衬砌钢筋隧道衬砌的移动工厂式流水线工作，提高了施工效率。
