一种新型高精度施工测量接收标靶的设计与应用

Design and Application of a New Type of High-precision Receiving Target for Construction Survey

随着超高层建筑不断往高耸方向发展,参建各方对超高层建筑的施工测量精度提出了更高的要求。目前超高层建筑测量仍存在作业粗糙、误差较大等问题,因此,开发了一款用于超高层建筑高精度施工测量的超高层建筑测量接收标靶。接收标靶由固定装置、位移调节装置、水平调平装置、棱镜装置几大部分组成。在施工测量中,可通过该接收标靶快速高效完成高层建筑轴线竖向投测、垂直度测量、施工测量放线和高程传递等工作;该接收标靶改进了目前常用全站仪天顶距法中存在的低效操作反光片、玻璃板不水平、测量精度低等问题,建议在超高层建筑施工测量工作中推广使用。

With the development of super high-rise buildings,all parties involved in the construction put forward higher requirements for the construction survey accuracy of super high-rise buildings.At present,there are still some problems in the survey of super high-rise build‐ings,such as rough operation and large error.Therefore,develops a survey receiving target for high-precision construction survey of super high-rise buildings.The receiving target consists of fixing device,displacement adjusting device,leveling device and prism device.In the con‐struction survey,the receiving target can be used to quickly and efficiently complete the vertical survey of the axis of high-rise building,verticality survey,construction survey setting-out and elevation transmission,etc.This receiving target improves the problems of inefficient op‐eration of reflector,non-level glass plate and low measurement accuracy existing in the zenith distance method of total station at present,and it is suggested to be popularized and used in the construction survey of super high-rise buildings.
