简述金属波纹管在危桥加固中的应用简述金属波纹管在危桥加固中的应用 摘要：本文就以古塘桥加固工程为例介绍金属波纹管在危桥加固的一种应用方法，它还可以采纳定制管片内衬方法（非整管）用于多种跨径拱桥加固，以及用于新、改建公路的桥涵、通道修筑，相对于钢筋混凝土涵洞，金属波纹管涵洞的应用，一方面节约了大量的石材、水泥，有利于环保，另一方面建设工期可以大幅度缩短，不仅加快了建设步伐，充分体现了建设工期缩短相对运营时间增加的经济效应，在抢险、保通工程中应用金属波纹管更能体现其明显的社会效应和经济效益，金属波纹管必将具有宽阔的应用前景。 关键词：金属波纹管;危桥;加固;应用 Abstract: In this paper, the ancient Tangqiao reinforcement project as an example to introduce metal corrugated pipe application method of reinforcement in the bridge, it can also be used to customize the segment lining method ( non-integral tube ) for multiple span arch bridge reinforcement, as well as for the new, rebuilt highway bridge, channel construction, compared with reinforced concrete culvert, application of metal bellows culvert, on one hand, saving a lot of stone, cement, is conducive to environmental protection, on the other hand, the construction period can be shortened greatly, not only accelerated the pace of construction, fully embodies the construction time shorten the economic effects of increased relative operation time, application of metal bellows in emergency, traffic engineering tube which can reflect more obvious social effects and economic benefits, metal corrugated pipe will have broad application prospects.
