The Research Of Yuan Liang Shan Tunnel Grouting Water Plugging Plan And Construction Technology

In specialty long tunnel construction process will inevitably meet high pressure, rich water, karst etc. bad geological condition. During the construction often occur high pressure water gushing and axon happened mud phenomenon. For construction and environmental protection can bring the huge difficulties and safe hidden trouble. Build long tunnel is a challenging world problems in high pressure , rich water. From the following aspects carry out the research of long tunnel grouting water plugging plan and construction technology in high pressure , rich water, karst.Analysis of the choice of the ways of the grouting standards through the grouting scheme design research of yuan liang shan tunnel.Determine the thickness of the grouting reinforcement ring according to mechanical simulation force requirements.Choice of reasonable grouting design parameters through the mechanics calculation and engineering analogy means. During the grouting process effectively prevents high pressure water gushing and axon happened mud phenomenon.Analysis and research the grouting material of yuan liang shan tunnel.Compared with the cement grouting material grouting and chemical grout grouting draw:Using superfine cement, TGRM superfine type slurry grouting are much better than using chemical grout water The former have lthe ow cost, convenient field configurable, the technology of construction is simple, high strength, not pollute the environment features.Analysis and research the Grouting construction technology of yuan liang shan tunnel. For construction process optimization provides the basis and raising the working efficiencythrough comparing the three grouting construction technical solution applicable condition. Ensuring the tunnel on schedule, safely and successfully completed. Raise the working efficiency.Analysis and research fore geological forecast of yuan liang shan tunnel. More accurately the proven influence geologic condition. For the dynamic design and construction provides accurate reliable geologic information and achieved good geological forecast conclusion.
