摘　　要：文中以渝万项目站前五标一分部珍溪河双线大桥的2处筑堤围堰施工为工程背景,综合考量周围地质水文状况,根据河水长时间处于低水位的实际情况,通过采用筑堤围堰、帷幕注浆、钢板桩围堰等方法,其中帷幕注浆为重点控制项目,确定注浆材料、注浆工艺与注浆孔的布置。此次施工速度快、效率高、成本低、阻水效果好。研究对水中筑堤围堰帷幕注浆施工技术进行总结,对类似工程具有一定的参考意义。In the Bid 5 of Chongqing—Wanzhou Project,the embankment cofferdam construction is at two locations of the Zhenxi river double-track bridge in section 1.Considering the surrounding geological and hydrological conditions and the long-term low water level of the river,a construction technology consisting of embankment cofferdams,curtain grouting,and steel sheet pile cofferdams is proposed,with curtain grouting as the key control measure.The grouting materials,grouting process,and grout hole layout were determined accordingly.This construction demonstrated high speed,efficiency,low cost,and effective water blockage.The summary of the embankment cofferdam curtain grouting technique in this project provides a valuable reference for similar engineering projects.
