泥水盾构施工中同步注浆浆液的试验控制

Test control on synchronous grouting slurry used in slurry shield construction

广深港客运专线狮子洋隧道泥水盾构施工采用了同步注浆技术,有效控制了地表沉降,通过对注浆浆液配合比和施工的试验控制,注浆效果理想。

Slurry shield construction on Shiziyang Tunnel of Guangzhou-Shenzhen-Hong Kong passenger dedicated line controls the ground surface settlement effectively.Through the grouting slurry ratio and construction of test control, grouting effect is satisfactory.
