Anti-collision wall is a kind of safety protection facility for bridges. Because the anti-collision wall is located in the bridge deck system and in the most intuitive position of the bridge, it requires high quality indicators such as geometric size, surface finish, smoothness and so on.
但防撞墙下部蹄形部位呈特殊的反弧形,在施工浇筑过程中蹄部前侧面气泡极难排出,拆模后往往出现较为密集的大小气泡,同时因在安装后的悬空板上现浇,给立模带来很大的难度,模板的接缝部位和底部常常由于漏浆出现蜂窝麻面等表面缺陷

After demolition of the mould, more dense bubbles often appear. At the same time, the cast-in-situ suspension plate after installation brings great difficulty to the vertical mould. The joint and bottom of the formwork are often due to leakage of slurry. Honeycomb hemp surface and other surface defects
