跨南水北调干渠工程交通桥施工技术

The construction technique of South-North water transfer canal traffic bridge

交通桥施工在跨南水北调干渠工程中是难度较大的项目。由于南水北调工程规模大,工期紧迫,交通桥的施工质量和安全直接制约调水工程的施工进展。为保证南水北调蒲阳河东阳各庄公路桥施工,结合该工程特点,采用人工挖孔桩技术,预制梁采用后张拉法施工技术,有效地解决了东阳各庄交通桥施工难题。

Traffic bridge in highway construction in the middle and is a common construction project, but in the trunk cross-South-North Water Diversion Project is a project more difficult. First, the construction of water conservancy professional team of construction industry, there are many technical difficulties; the second is how to channel in the South- North Water Diversion turnk traffic bridge construction to ensure construction quality and safety. Mid-route of South-North Water Transfer of emergency water supply project Dongyang River channel inverted Coal Highway bridge project is investigated Zhang Shi highway bridge construction, combined with the engineering characteristics of the use of hand-dug pile technology, the use of precast post-tensioned beams Rafah construction techniques to effectively solve the Dongyang Coal Bridge traffic problems, traffic trunk for cross-bridge-north water diversion project has provided technical support.
