The invention discloses a method for controlling the precision of a directly-buried bolt through a sleeve. The method comprises the steps that the sleeve is arranged on the upper portion of the directly-buried bolt when the directly-buried bolt is buried, and the length of the sleeve is 1/4-1/3 of the length of the directly-buried bolt; concrete is poured to the primary surface elevation, and the sleeve is not filled with concrete; the directly-buried bolt is rechecked before equipment is installed, if the directly-buried bolt is not rechecked to be qualified, the bolt is subjected to cold bending to the range meeting the requirement, then the equipment is installed, and primary grouting is conducted in the sleeve after the equipment is installed and preliminarily fixed; and secondary grouting is conducted after the equipment is finely adjusted. According to the method for controlling the precision of the directly-buried bolt, the process is simple, and the precision of the directly-buried bolt is directly controlled through the sleeve; compared with a traditional sleeve method, a steel plate is not needed, a large amount of labor and materials are saved, the measurement requirement is lowered, construction auxiliary materials are reduced, and the construction procedure is simplified; and the position of the bolt can be locally adjusted, the operability of the method is higher than that of a positioning frame method, and the method has great application prospects.
本发明公开了一种使用套筒对直埋螺栓进行精度控制的方法，步骤为：在埋设直埋螺栓时在其上部布置套筒，套筒的长度为直埋螺栓长度的1/4～1/3；浇筑混凝土至一次面标高且套筒内不灌混凝土；设备安装之前对直埋螺栓进行复核，如复核不合格则冷弯螺栓到符合要求范围内再安装设备，等设备安装完成并初步固定后向套筒内进行一次灌浆；设备精调之后进行二次灌浆。本发明的直埋螺栓精度控制方法，工艺简单，直接通过套筒对直埋螺栓进行精度控制；相比于传统套筒法，无需钢板，节省大量人工及材料，降低了测量要求，减少了施工辅材材料及简化了施工程序；能够对螺栓位置进行局部调整，其可操作性相比于定位架法更高，极具应用前景。
