城市化进程和城市生活节奏的加速,为城市对其道桥建设的扩张效率和质量提出了新的要求,而加快道桥建设效率要从规划、勘测、设计、施工等多方面共同进行。本文就单从道桥勘测和施工前准备阶段中,通过使用全站仪来提高测图、放样效率做以简要分析。 The accelerating pace of urbanization and the pace of urban life have set new demands for the city to expand the efficiency and quality of its construction of the Daoqiao. Accelerating the efficiency of the construction of the Daoqiao should be carried out in many aspects such as planning, surveying, design and construction. In this paper, just from the bridge survey and pre-construction phase, by using the total station to improve the mapping, lofting efficiency to do a brief analysis.
