Rapid construction method for open-cut tunnel lining ring-forming steel bars
The invention discloses a rapid construction method for open-cut tunnel lining ring-forming steel bars. The rapid construction method comprises the steps that S1, the ring-forming steel bars are machined and manufactured; the ring-forming steel bars are divided into lower embedded steel bars and upper ring-forming steel bars, and the upper ring-forming steel bars are divided into upper arc steel bars and arc-shaped steel bars on the two sides; s2, lower embedded steel bars are installed; s3, a plurality of arc-shaped steel bars are sequentially hoisted to an arc-shaped steel bar jig frame, placed at fixed intervals according to the design requirement and fixed through a fixing clamp to form a whole, then the whole is hoisted to the position above the formwork trolley, the fixing clamp is taken down, and the arc-shaped steel bars directly fall into positioning clamping grooves of a formwork of the formwork trolley in sequence; s4, ring-forming steel bars are connected; and the embedded steel bars, the arc-shaped steel bars on the two sides and the arc-shaped steel bars are connected, and connection construction of the ring-forming steel bars is completed. The technical means that traditional ring-forming steel bars must be positioned, installed and constructed in situ is changed, the construction efficiency of the ring-forming steel bars is improved, and the construction cost is reduced.
本发明公开了一种明挖隧道衬砌成环钢筋快速施工方法，包括步骤S1、成环钢筋加工制作；将成环钢筋分为下部预埋钢筋及上部成环钢筋，将上部成环钢筋划分为上部的圆弧钢筋和两侧的弧形钢筋；步骤S2、安装下部预埋钢筋；步骤S3、将多根圆弧钢筋依次吊装至弧形钢筋胎架上，按照设计要求的固定间距摆放，并通过固定夹具固定，使其形成为整体，然后整体吊装至模板台车上方后，取下固定夹具，多根圆弧钢筋依次直接落至模板台车模板的定位卡槽内；步骤S4、成环钢筋连接；将预埋钢筋、两侧的弧形钢筋以及圆弧钢筋连接，完成成环钢筋的连接施工。本发明改变了传统成环钢筋必须在原位定位安装施工的技术手段，提升了成环钢筋施工效率、降低施工成本。
