CGM waterproof type grouting material how to governance the tunnel disease

CGM waterproof type grouting material running online tunnel along with the extension of the period of service, geological structure, the construction quality is bad, the shrinkage and creep of concrete, groundwater activity, and the function of the damage to the surface of the human activities, the arch tunnel wall crack, metal shed, leaking, formation of the mud pumping line. Line how much a fusion, is not easy to insist on. Health branch pipe line, YangAnXian tunnel crack damage in different degrees. Although past eruptions concrete and steel fiber concrete methods for reinforcement, but some of the tunnel disease is increasingly developed, and the safety of operating line formed great blackmail. In recent years, with the further research on tunnel diseases, the new-style waterproof material research and development, to business line inductive control tunnel disease found a feasible path. The author is my section on tunnel construction practice of crack damage over the years, in line tunnels K472 + 351 ebony beam crack damage regulation, for example, to clarify the role of CGM waterproof type grouting material in use.
