钢波纹涵管也叫波纹管涵,是指铺埋在公路、铁路路下的涵洞用的螺纹波纹管,它是由波形钢板卷制成或用波形钢片组拼成的圆形钢结构管。金属波纹管涵的波纹结构可使涵洞路面受力合理,荷载分布均匀,并具有一定的抗变形能力,能解决北方寒冷地区(霜冻)对桥梁和管涵砼结构的破坏问题;

Steel corrugated culvert pipe, also known as corrugated pipe culvert, refers to the threaded corrugated pipe used for culverts buried under highways and railways. It is a circular steel structural pipe made of corrugated steel plates or assembled with corrugated steel sheets. The corrugated structure of metal corrugated pipe culverts can make the road surface of the culvert stress reasonable, load distribution uniform, and have a certain degree of deformation resistance, which can solve the problem of damage to the concrete structure of bridges and pipe culverts in cold northern regions (frost);

使路表面没有伸缩缝,提高行车舒适性;有利于改善软土地基结构与路堤交界处的“错台”现象,提高行车安全性。波纹管涵的工后营运、养护成本低,工程实际造价也低于同类跨径的桥梁、涵洞。钢波纹涵管进出口也可按照边坡比例做成斜口,加工波纹管管径范围0.5~8 m,管壁厚度为3 mm~7 mm,能够满足填土0.5 ~40 m厚的需要。

Make the road surface without expansion joints to improve driving comfort; Beneficial for improving the "staggered platform" phenomenon at the junction of soft soil foundation structure and embankment, and enhancing driving safety. The post construction operation and maintenance costs of corrugated pipe culverts are low, and the actual engineering cost is also lower than that of bridges and culverts with similar spans. The inlet and outlet of steel corrugated culvert pipes can also be made into inclined openings according to the slope ratio. The diameter range of processed corrugated pipes is 0.5-8m, and the wall thickness is 3-7mm, which can meet the needs of filling soil with a thickness of 0.5-40m.

钢波纹管涵在城市地下布局中的应用具有一系列显著优势,这些优势主要体现在以下几个方面:

施工便捷性:钢波纹管涵的生产、管体拼装与土建工作可以分开同时实施,这大大缩短了施工期。相比传统的施工方法,如钢筋砼拱涵的施工,钢波纹管涵的施工周期更短,所需的人力和物力资源也更少。此外,由于其重量轻,现场吊、拼装通常只需要2~3周,且参与的人员和机械较少。这种快速的施工方式有助于减少因施工而引发的民怨,同时使工程更早地交付使用。

经济性:钢波纹管涵的造价相比同等规格的拱涵要低。通过测算比较,钢波纹管涵平均每延米的造价能够节约一定成本。考虑到其施工便利以及地基处理等方面可能节约的成本,其经济性更为可观。

环保性:钢波纹管涵在制造和使用过程中减少了常规建材如水泥、砂石等的使用,这有助于减少环境污染,体现了其环保低碳的特性。在当前环保意识日益增强的背景下,这种环保优势显得尤为突出。

结构优势:钢波纹管涵具有刚性和柔性,结构受力合理,荷载分布均匀,具有一定的抗变形能力。这种结构特性使其能够适应不同的地质条件和变形要求,特别适用于地基承载力低的地区和特殊地质环境,如软土、膨胀土、湿陷性黄土等地震多发地区。此外,其变形性能优越、抗变形和沉降能力强,能够有效避免因地基不均匀沉降对涵洞的破坏。

维修便利性:在一些特殊区域和路段,钢波纹管涵的维修相对方便。其连接处无缝隙,可以通过在管侧上钻孔,填充碎石并喷射砂浆,以增加管涵和原始涵洞的完整性。这种维修方式简单易行,能够有效解决不均匀沉降对涵洞造成的损坏问题。

综上所述,钢波纹管涵在城市地下布局中的应用具有施工便捷、经济性好、环保低碳、结构优势以及维修便利等诸多优势。这些优势使得钢波纹管涵成为城市地下布局中一种理想的选择,有助于提升城市基础设施的质量和效率。
