全站仪在系杆拱桥拱架拼装时的应用

Application of Total Station Instrument in the Assembly of Arch Bridge and Arch Centering

近年来系杆拱桥越来越多地出现在人们的视野率,现在的系杆拱桥多采用钢管混凝土系杆拱,由于系杆拱桥跨径较大,难以一次性制作成型,一般采用岸上拼装整体吊装或部分吊装的形式施工,系钢拱的拱架拼装就成了系杆拱桥施工中重要的一环,全站仪的应用提高了拱架拼装工作效率。

In recent years, the arch bridge appears more and more frequently in people's eyes, the present arch bridgemostly uses concrete-filled steel tube arch centering, due to the large span of arch bridge, it is difficult to achieveone-time molding, the shore assembly of integral hoisting or part of hoisting is generally adopted for construction,steel arch centering assembling becomes an important link of arch bridge construction, the application of total stationinstrument improves the assembly working efficiency of arch bridge.
