随着科学技术的发展,工业设备安装工程中的安装精度要求越来越高,尤其是大跨度、长距离、高速运转的自动化生产线的设备安装,如造纸生产线设备的安装,其水平度及垂直度的允许偏差均仅为0.3mm。设备安装的精度取决于地脚螺栓的预埋精度,而在较大范围内地脚螺栓的预埋精度则由测量放线的精确度所决定。因此掌握整套的高精度测量放线技术是保证设备安装精度的基础。一、测量放线准备及流程
With the development of science and technology, the installation precision in industrial equipment installation projects is getting higher and higher, especially in the equipment installation of automated production lines with long-span, long-distance and high-speed operation, such as the installation of horizontal and vertical Degree of tolerance are only 0.3mm. The accuracy of equipment installation depends on the pre-buried bolt precision, and in a wide range of pre-embedded precision bolt anchored by the measurement of the accuracy of the decision. Therefore, to master the complete set of high-precision measurement of line technology is to ensure the accuracy of equipment installation basis. First, the measurement of the preparation and process
