| Abstract: | For a small curvature radius and a large curvature pipe jacking construction，the relative measurement is difficult.Traditional one step measurement and laser guided measurement has been unable to meet the construction requirements，therefore，this paper proposes an advanced automatic guidance pipe jacking system.Take jianxian Xinnong，Fuzhou city 220kv transmission line’s three curved pipe jacking engineering for example，through algorithm optimization and actual pipe jacking project analysis，this paper solves the automatic guidance problems of automatic guidance pipe jacking system in such works.At the same time，it elaborates methods of automatic guidance and analyzes accuracy of pipe jacking guide，thus indicate the superiority and reliability of this system in pipe jacking project.Finally，through the application of the automatic guidance system it solves the encountered measuring problems in the process of guidance，ensuring accurate conduction of jacked pipe. |
