Information
At present, the application of steel corrugated pipes is gradually extended from the original highway culvert to highways, municipal highways, railways, bridges, agriculture, ports, airports, municipal pipelines, industrial, commercial buildings, civil residences, mines, old infrastructure restoration, New energy and military. According to surveys by relevant US agencies, in recent years, steel corrugated pipes accounted for more than 30% of the large-caliber pipeline market in the United States, and the annual sales of corrugated steel pipes in the United States reached 15 billion US dollars. In addition, East Asian countries such as Japan and South Korea have also used corrugated pipe culverts since the end of the 20th century.
Steel corrugated pipes have many advantages in engineering applications, such as high structural strength, which is 1 to 3 times the strength of reinforced concrete; long service life, up to more than 100 years; light weight, convenient construction, and only 10 times the weight of cement products % ~ 20%, and the civil construction and pipe assembly can be implemented simultaneously and separately. The construction period is short and the construction period can be shortened by half. The axial flexibility is applicable to areas with complex geological conditions and severe settlement; in areas with severe construction conditions Or under special geological conditions, the actual cost of the project is lower than that of reinforced concrete bridges and culverts of similar spans; almost no maintenance and low operation and maintenance costs; centralized factory production can be carried out without being affected by the environment, which is conducive to reducing costs and quality control; Easy installation on site, no need to use large equipment; environmental protection and low carbon, reducing or completely abandoning the use of conventional building materials, such as cement, yellow sand, stone, wood, is conducive to environmental protection.
