屏山岷江大桥主墩钢围堰封底混凝土施工质量控制

摘要

The cloth point catheter, end mouth dangling and gradient height change model is adopted in the bottoming concrete casting of steel cofferdam of Minjiang Bridge in Pingshan. Single point feed and order are also applied to take its casting speed and construction quality under effective control.%屏山岷江大桥钢围堰封底混凝土浇筑采用布料点导管底口悬空高度呈梯度变化的方式布设，单点供料单点顺序进行封底混凝土浇筑，使钢围堰封底混凝土的浇筑速度及施工质量得到有效控制。
