富水砂卵石地层中大直径泥水盾构同步注浆技术

Synchronous grouting of large diameter slurry shield in water-rich sandy gravel stratum

通过统计分析盾构掘进相关技术资料,综合考虑富水砂卵石地层中泥水盾构掘进参数、泥浆参数、盾构姿态、地层变形机理等信息,确定泥水盾构在砂卵石地层中掘进时,同步注浆主要技术参数间的经验公式,指导类似工程施工。

Through the statistical analysis of the technical data which based on shield tunneling, comprehensively considering the information of water-rich sandy gravel stratum, such as the tunneling parameter of the slurry shield machine, slurry parameter, shield posture and stratum deformation mechanism information, the empirical formula of the main parameters of synchronized grouting technologies is determined while the slurry shield is tunneling in sandy gravel stratum. It can guide the similar project construction.
