摘要
北京朝阳北路热力暗挖隧道紧临白家楼桥基础,针对下穿东五环路主路、白家楼桥加筋土、浆砌块石挡墙和地铁因司等风险源,采取深孔注浆止水帷幕、双排水导管超前支护等技术措施,确保隧道在非降水条件下的无水作业,既保证了市政基础设施的安全运行,又保证了施工安全。
Covered excavation heating tunnel located on Chaoyang North Road is adjacent to the foundation of Baijialou Bridge. This project passed through the eastern 5th-ring road, reinforced earth of Baijialou Bridge, masonry retaining wail and subway tunnel, so some technical measures were adopted, such as deep hole grouting water-stop curtain and double drainage pipeline advance support, etc., to guarantee water-flee construction without dewatering. Safe operation of municipal infrastructure and safe construction were realized.
