微型顶管技术在复杂环境条件下排水管道工程中的应用

Application of Micro-pipe Jacking Technique in Drainage Pipeline Engineering under Complex Environment

微型顶管技术是一种小口径管道非开挖施工的顶管施工工艺,技术成熟于德国和日本。因其施工占地小、施工周期短、实施精度高等特点,近几年在复杂环境条件下的市政排水管道工程中广泛应用。现详细阐述微型顶管技术的工艺原理,并结合实际工程案例,介绍微型顶管技术在市政排水管道工程中的施工工艺。

The micro-pipe jacking technique is a pipe jacking construction technology for the trenchless construction of small-diameter pipes, which matures in Germany and Japan. Because of its characteristics of small construction area, short construction period and high implementing precision,the technique has been widely applied in the municipal drainage pipeline projects under the complex environmental conditions in recent years. The technological principle of the micro-pipe jacking technique is expounded in detail. And combined with the practical engineering cases, the construction technology of micro-pipe jacking technique in municipal drainage pipeline engineering is introduced.
