本发明公开了大体积砼循环冷却水管快速定位施工方法及定位装置，包括水管定位板和钢筋定位板，所述水管定位板的一端设有水管吊钩，所述水管定位板的另一端设有定位块，所述定位块上贯穿开设有凸形槽，所述凸形槽的内部铰接有自锁卡片的一端，所述凸形槽的内部对称固定连接有U形弹片的一端，本发明不仅固定方便快捷，还能使定位点可任意调节，同时在使用中不会对受力钢筋的受力性能以及观感质量造成影响，从而克服现有技术的不足，具有制作安装方便、可任意调节定位点、并且使用便捷方便的优点；此外还具有节能环保、感观大方、能满足定型化周转使用的要求等优点。经试验使用证明，本发明具有很好的推广意义。

The invention discloses a quick positioning construction method and positioning device for a large-volume concrete circulating cooling water pipe. A water pipe positioning plate and a steel bar positioning plate are included, a water pipe lifting hook is arranged at one end of the water pipe positioning plate, a positioning block is arranged at the other end of the water pipe positioning plate, aconvex groove is formed in the positioning block in a penetrating mode, one end of a self-locking card is hinged to the inner part of the convex groove, and one ends of U-shaped spring pieces are symmetrically and fixedly connected to the inner part of the convex groove. According to the quick positioning construction method and the positioning device, fixation is convenient and fast, a positioning point can be adjusted arbitrarily, meanwhile the mechanical performance and the appearance quality of a stressed steel bar cannot be affected in use, thus the shortcomings of the prior art are overcome, and the advantages that manufacturing and installing are convenient, the positioning point can be adjusted arbitrarily, and use is convenient and fast are achieved; in addition, the advantages ofenergy saving and environmental protection, generous sense, meeting the requirements of stereotyped turnover use and the like are further achieved; and it is proved by test and application that the quick positioning construction method and the positioning device have good popularization significance.
