某地铁隧道联络通道注浆加固及开挖施工

Grouting Reinforcement and Excavation of a Connecting Passage in Metro Tunnel

介绍某地铁隧道正线联络通道砂层断面暗挖法施工过程中,在"连续墙+搅拌桩"地面加固方案实施后,采取隧道内水平注浆方式对含水砂层进行二次加固,效果良好,保证了联络通道开挖施工的安全。

This paper introducese of a subway tunnel are lines connecting passage in sand layer section tunneling method of construction process,the continuous wall and mixing pile on the ground after the implementation of reinforcement,grouting way to the tunnel level of a second water-bearing sand layer reinforced with good results to ensure the safety of contact channel excavation.
