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;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。
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 Ycdcbj.com structure of metal corrugated pipe culverts can make the road surface of the culvert stress reasonable, load distribution uniform, Cqjngd.com,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); Make the road surface without expansion joints to improve driving comfort; Cqkfrf.com,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, Cqlnjx.cn,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.
钢波纹管涵在高速公路中有广泛的应用,其优势体现在多个方面。今天就由江能管道与大家一起来分享一下吧!
首先,钢波纹管涵洞主要由钢板和波纹管组装而成,具有结构合理、重量轻、施工方便等特点。在高速公路建设中,它常被用于涵洞、方桥、排水井等地下结构和简易桥梁的建造。这种结构轻便,建造速度快,可以大大缩短公路施工的时间和成本。

其次,钢波纹管涵洞具有优良的经济性。与钢筋混凝土板涵相比,金属波纹圆管涵的道路建设直接成本可以降低10%~20%。这主要是因为金属波纹管是一种柔性结构,允许涵洞纵向沉降和变形,对基础的承载能力要求不高,不需要重新填充基础。

再者,钢波纹管涵洞适应性和可靠性高。它适用于各种地质和环境条件,特别适合于软土、膨胀土、湿陷性黄土等地基承载力较低地区和地震多发地区。其结构具有可靠的质量保证体系,可以省去大量频繁的维修工作,从而降低维护成本。

此外,钢波纹管涵洞还具有良好的环保性。它基本不用水泥、石材、木材等常规建筑材料,减少了高速公路沿线的环境污染,对环境保护意义深远。
最后,钢波纹管涵洞的施工技术和工艺要求相对简单。在施工过程中,无需在现场安装大型设备,这有助于进一步减少对环境的影响。同时,其施工流程包括材料设备就位、测量放样、基坑开挖、基底及砂垫层、管身安装、密封及防腐处理、回填、进出口处理等阶段,每一步都有明确的工艺要求,保证了施工的质量和效率。

综上所述,钢波纹管涵在高速公路中的应用广泛,其优势主要体现在施工方便、经济性好、适应性和可靠性高、环保以及施工技术和工艺要求简单等方面。这些优势使得钢波纹管涵在高速公路建设中具有广阔的应用前景。
