工程施工中通常用经纬仪来进行水平角和竖直角测量。我单位在某国防工程的施工中,利用经纬仪的功能、特点进行水平测量,取得到了比较满意的结果。该工程为综合火炮试验阵地,土建施工要求在3米厚的钢筋混凝土基础上预埋4个螺栓群。每个螺栓群由18个(?)42螺栓组成。工程要求每个螺栓的空间位置与真坐标允许偏差1毫米。由于大体积钢筋混凝土浇捣时螺栓的空间位置难以
Theodolites are often used for surveying horizontal and vertical angles during construction. In the course of construction of a national defense project, our company made use of the functions and characteristics of theodolites to measure the level and achieved satisfactory results. This project is an integrated artillery test site. The civil construction requires that four bolt groups be embedded on a 3-meter thick reinforced concrete foundation. Each bolt group consists of 18 (?) 42 bolts. The project requires a tolerance of 1 mm between the spatial position of each bolt and the true coordinates. Due to the difficult position of bolts when pouring large volumes of reinforced concrete
