激光接力投点导向控制方法的研究与应用

Application and research for Laser relay point of the orientation control

宝泉抽水蓄能电站引水系统斜井施工中,由于多种因素的影响,反导井无法实现测量控制。施工单位引进国产的新工艺激光,利用国产激光安装方便的特点,在斜井上下安装了两套激光系统,达到了控制反导井的目的。反导井贯通精度远远小于规范规定,且工期提前。该方法的研究与应用完善了斜井施工测量工法,彻底解决了斜井反导井测量控制的难题。

During the construction of the inclined shaft in the water diversion system of Baoquan Pumped Storage Power Station, for a variety of factors, the measurement control can not be achieved in the reverse well. The contractor introduced homemade latest technique laser which posses easy to install, and two sets of laser system are installed from top to bottom in the inclined shaft to realized back well control. Its perforation precision is far smaller than standard, and the construction period short. The method of study and application has improved construction measurement of the inclined shaft, and resolved the difficult problems of the reverse measurement control in inclined shaft.
