Abstract:For a small curvatureradius and a large curvature pipejacking construction,the relative measurement is difficult.Traditional onestep measurement and laserguided measurement has been unable to meet the construction requirements,therefore,this paper proposes an advanced automatic guidance pipejacking system.Take jianxianXinnong,Fuzhou city 220kv transmission line’s three curved pipejacking engineering for example,through algorithm optimization and actual pipejacking project analysis,this paper solves the automatic guidance problems of automatic guidance pipejacking system in such works.At the same time,it elaborates methods of automatic guidance and analyzes accuracy of pipejacking guide,thus indicate the superiority and reliability of this system in pipejacking 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.
