南方多雨山区地质复杂,具有柔性的钢波纹管在不均匀沉降地基涵洞施工中有着明显的优势。结合麻武高速公路中钢波纹管涵工程实例,从施工的主要环节介绍了南方多雨山区大直径钢波纹管涵的施工工艺及施工技术,并给出了钢波纹管涵背回填和端头施工中所采取的有效措施,为大直径钢波纹管涵在类似地基中的推广应用提供了借鉴。
The geology of the rainy mountain area in the south is complex, and the flexible steel bellows has obvious advantages in the construction of the foundation culverts with uneven settlement. Combined with the example of the steel corrugated culvert culvert in Mawu Expressway, the construction process and construction technology of large diameter steel corrugated culvert in southern rainy mountain area are introduced from the main links of the construction. And the backfilling and end construction of steel corrugated pipe culverts are given In the effective measures taken for the large diameter steel corrugated pipe culvert in the similar ground to promote the use of provided a reference.
