Initially, steel piles were used as the foundations for the pier columns and piers of iron bridges that were built over rivers. Then, the steel pile has been used as both a foundation pile of an iron bridge and a pillar of a pier of the iron bridge. Since then, steel piles have been adopted as the foundation for high-rise buildings. Needless to say, a high-rise building needs a strong foundation, and various foundation piles have been used, but recently, steel piles have been adopted as the foundation piles of high-rise buildings to achieve results. Also, in order to make the shallow sea that spreads along the coast into land by reclamation work and build facilities on the land of the soft ground, it is necessary to improve and strengthen the soft ground. Therefore, a large number of sand piles are driven to drain water, and although it takes some time, it has achieved some results. There is a need for improvement and reinforcement of such soft ground and the use of concrete piles is widespread. However, the strength of concrete piles is lower than that of steel piles, and is particularly weak against bending and pulling. From this point, steel piles are expected to become more popular than concrete piles except in special fields. Therefore, the steel pipe pile was technologically developed. Therefore, we succeeded in filling the concrete material into the steel pipe pile rather than making it into a tubular shape and increasing the strength of the concrete pile for use as a foundation pile. And in the tubular part of the steel pipe pile,
First, the H-section steel is inserted, and after that, when the concrete material is filled and used as a foundation pile, its strength is
Further strengthened. As such, in foundation work, the steel pile construction method is superior to other construction methods. The types of steel piles used in the steel pile construction method are generally steel pipe piles and H piles. The tubular portion of the steel pipe pile has a circular cross section and a square cross section. Equipment with a square cross-section is easy to manufacture during manufacturing, but it is not always easy to efficiently manufacture products with different dimensions. Although it is complicated, it is easy to efficiently manufacture products having different sizes, and flat steel plates are often rounded and the abutting portion or overlapping portion thereof is welded. And
It is easy to appropriately satisfy the required strength by considering not only the diameter but also the thickness of the steel sheet.
