The Application of Automatic Lubrication Grouting System in Long-distance Pipe-jacking Tunnel Construction

Abstract

In the pipe jacking tunnel construction process, smooth grouting was a very important work, and was also a key technique of pipe jacking construction, especially in a long distance pipe jacking tunnel construction. Application of grouting technology in lubrication has played a very important role. In order to ensure the quality of grouting, effective lubrication of the drag reduction effect, reducing the pipe jacking resistance, improving the efficiency of pipe jacking construction need to develop detailed lubrication grouting plans and measures. This paper introduces the application of automatic lubrication grouting system in the construction of long distance pipe jacking tunnel from the aspects of grouting purpose, selection of grouting materials and grouting technology.
