Construction method for concrete anti-collision guardrail on outer side of bridge
The invention discloses a bridge outer side concrete anti-collision guardrail construction method which comprises the following construction steps that S1, after a guardrail inner side steel formwork is fixed, a guardrail outer side steel formwork is installed; s2, the top end of a finish-rolled threaded steel bar on the outer side steel formwork penetrates through a reserved hole of the second channel steel, and a finish-rolled threaded steel nut and a gasket are installed on the exposed part; s3, counter-drawing lead screws are arranged at the bottom and the top of the guardrail steel formwork for connection; and S4, after all the guardrail steel formworks of one construction section are installed, steel pipes penetrate through the semicircular steel bars welded to the second channel steel, and the adjacent guardrail steel formworks are connected into a whole. The device is practical and convenient, the height of the outer side steel formwork can be adjusted, and the safety during disassembly can be guaranteed.
本发明公开了一种桥梁外侧混凝土防撞护栏施工方法，包括以下施工步骤：S1:护栏内侧钢模板固定后，安装护栏外侧钢模板；S2:外侧钢模板上精轧螺纹钢筋顶端穿过槽钢二的预留孔洞，外露部分安装精轧螺纹钢螺母和垫片；S3:护栏钢模板底部、顶部设置对拉丝杆连接；S4:安装完成一个施工段所有的护栏钢模板后，使用钢管穿过槽钢二上焊接的半圆形钢筋，将相邻的护栏钢模板相连为一个整体。实用方便，能够对外侧钢模板高度进行调节，且能保证拆卸时的安全性。
