Electronic Tachometer Eccentric Lofting New Method for Measuring and its Reliability |
| |
| Abstract: | Currently in engineering surveying, electronic tachometer has been widely used, based on electronic tachometer lofting applications in engineering requirements for lofting points with measurement site must pass visual, however, in the actual work of these two points are often impassability visual. Therefore, this paper presents a new electronic tachometer lofting method, and a detailed discussion on the lofting principle, accuracy and reliability. At the same time, this paper based on the Datang crown close mountain GongSiJi units on the big power limited pressure small project main workshop of pile foundation A standard engineering projects, demonstrates the method of lofting results within and outside precision. It has been found that, this paper expounds the lofting method in different accuracy requirements engineering is feasible and reliable. |
