摘要
某特大桥主墩承台体量大、埋深大、水位变化复杂,河床承台施工范围内多为砂砾层,围堰结构设计复杂,工期紧等特点。采用超深钢围堰进行施工,圆满完成施工任务。
The main pier cap of a certain super large bridge has a large volume,deep burial depth,and complex water level changes.The construction scope of the riverbed cap is mostly composed of gravel layers,and the design of the cofferdam structure is complex and tight.Construction was carried out using ultra deep steel cofferdams,and the construction task was successfully completed.
