Abstract:Based on the main pipe project of Chengdu Maojiawan sewage treatment plant, the long-distance large-diameter mud-water balance mechanical-jacking construction under water rich geology is studied, and a linetype control method for long-distance large-diameter mud-water balance pipe jacking construction is put forward. Through the research on the jacking force calculation, measurement control and jacking attitude of large diameter mechanical pipe jacking,an intelligent deviation correction control method for long-distance large-diameter mud-water balance pipe jacking construction under water rich geology is proposed. The successful implementation of the project has confirmed the feasibility of the above mechanical pipe jacking control measures,which can provide reference for similar projects.
