Attitude Measurement for Underground Self-walking Tunneling

Self-walking tunneling is at present the most advanced technology to underground pipeline construction. One of the difficulties is orientation measuring technology, that involves if tunneling can keep along with designed line. There is no mature method for self-walking tunnelling. This paper, based on the eleventh five-year plan national science and technology subject, comprehensive utilization of total station and rangefinder and combination with the characteristics of the tunneller, researches a set of practical and low cost measurement method. The application shows that the method meets with the need of orientation measurement to curve tunneling.
