穿越钱塘江大堤的顶管工程施工技术

Pipe Jacking Construction Technology of Traversing Qiantang River Embankment

顶管施工穿越江河大堤具有一定的技术风险和难度。结合杭州市七格污水处理厂污水排江工程,介绍了顶管穿越钱塘江大堤的成功实践,分析了顶管施工可能引起的大堤沉降量,并据此采取了一系列施工技术措施,以减小对大堤的影响。结果表明,各项措施的实施有效保证了工程的顺利施工。

It is very difficult to traverse river embankment by pipe jacking construction. Combined with the river discharge project of wastewater from Hangzhou Qige WWTP, the successful experience of traversing the Qiantang River embankment by pipe jacking construction is introduced. The embankment settlement possibly caused by pipe jacking construction was analyzed, and a series of technical measures were taken to reduce the influence on the embankment. The results show that the implementation of the measures effectively ensures the successful completion of the project
