自动润滑注浆系统在长距离顶管隧道施工中的应用

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

摘要: 润滑注浆在顶管隧道施工中是一项非常重要的工作，也是一项关键的技术，尤其是在长距离顶管隧道施工中。为了保证注浆质量，有效起到润滑减阻的作用，降低顶管顶进阻力，提高顶管施工效率，需要制定详细的润滑注浆方案和措施。从注浆目的、注浆材料的选择、注浆工艺等方面介绍长距离顶管隧道施工中自动润滑注浆系统的应用。

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.
