依托郑卢高速公路大铁沟特大桥主墩施工,开发了主墩墩身、0号块托架同时施工,0号块施工在0号块托架施工完成前进行的施工方法。阐述了工程背景、技术介绍、具体施工方法及施工注意事项。该技术实现了现场快速施工,避免雨季对施工的影响,同时保证了施工质量和施工进度,大大节省了工程成本。通过该技术在此工程中的成功应用,很好地说明了此方法的科学性和可行性,为以后同类工程施工类似情况的解决奠定了良好的基础。
Relying on the construction of the main pier of the Dazetou Bridge on Zhenglu Expressway, the construction method of main pier pier body and No. 0 block carrier at the same time was developed. Construction method of No. 0 block construction was completed before the construction of No. 0 block carrier was completed. Described the project background, technical introduction, specific construction methods and construction precautions. The technology to achieve the rapid construction site to avoid the impact of the rainy season on the construction, while ensuring the construction quality and progress of construction, which greatly saves engineering costs. Through the successful application of this technology in this project, it shows the scientificity and feasibility of this method well and lays a good foundation for the solution of the similar situation of similar projects in the future.
