纵向悬砌工艺是在横向悬砌工艺~*的实践基础上发展的,其目的是取消横向悬砌法基肋下的拱架,使预制块拱桥可以在完全没有拱架支承的情况下进行拼砌合攏,以进一步节约木材,增大经济效果,同时为狭谷深涧问建拱创造有利条件。这一工艺的实践成功,使圬工拱桥的预制装配施工技术又向前迈进一步。 Longitudinal suspension technology is based on the practice of horizontal suspension technology * *, whose purpose is to eliminate the lateral suspension under the arch ribs under the ribs, so that prefabricated arch bridge can be completed without arch support Masonry together to further save the timber, increase economic efficiency, at the same time as the narrow valley Jian Jian arch create favorable conditions. The successful practice of this process has taken the prefabricated assembly construction technology of the Gongqiao arch bridge another step forward.
