穿越京杭运河输水管道顶管施工质量控制

摘要

杭州市余杭仁和水厂供水工程穿越京杭运河顶管施工中,根据地质情况采取技术措施,在淤泥质粉质粘土中进行180m长钢管顶进,不设中继间且不采用注浆减阻措施,取得了一次顶进成功,质量控制达到预期目标.%During pipe jacking construction of Yuhang Renhe Water Plant project of Hangzhou passing through Beijing-Hangzhou Grand Canal, technical measures are adopted according to geological conditions. 180m-long steel pipe is jacked in silty clay stratum without relay chamber and fraction-reducing measure. Successful one-off jacking is realized and expected quality control aims are reached.
