摘要
在上海市白龙港南线输送干线完善工程中,邻近顶管出洞口位置有1条600mm上水管线,顶管施工期间必须进行保护。首先介绍了工程遇到的问题,然后介绍了采取的树根桩保护技术措施。监测数据表明,顶管出洞施工过程中,树根桩对该上水管有很好的保护作用,沉降数据均在允许范围内,取得良好的经济效益和社会效益。
During construction of Bailonggang pipe jacking in Shanghai,root pile technology was adopted to protect 600mm water pipeline nearby.Firstly,the engineering difficulties were introduced in detail.The protecting technology was also discussed.The monitoring data shows that the root pile is very effective to restrict the deformation of water pipeline nearby.The settlement is controlled in allowable range.Good social and economic benefits are achieved.
