Proportioning Test of Grouting Material for Seabed Shield Tunnel
Aiming at the complex and changeful engineering geological conditions of the intake tunnel of Taishan nuclear power station, such as large diameter, large water pressure and long tunnel length, the proportion of slurry material is studied to ensure the grouting effect of shield. The controlling factors of grouting material, such as process performance, water dispersibility, preventing floatation and durability of segments, are analyzed. The performance indexes of high performance synchronous materials are discussed, and reasonable grouting materials and proportioning experimental instruments and equipment are selected and determined. Through the proportioning test of grouting material, the synchronous grouting material formulation, slurry configuration method and suitable grouting process are studied to improve the synchronous grouting effect and achieve the purpose of tunnel reinforcement and water stop. The engineering application shows that through the proportioning test, the mixture ratio of 1 and the mixture ratio of 9 grouting material can meet the needs of on- site construction, and the filling effect is good, so it has wide application value.
