At present, there are three types of steel piles commonly used in engineering construction, namely steel pipe piles, section steel piles, and steel sheet piles. Compared with other steel piles, steel pipe piles have their unique advantages in many aspects. Such as bending stiffness, single pile bearing capacity and many other aspects.
Analysis of the characteristics of steel pipe piles
1. Various specifications and options. At this stage, steel pipe piles are produced in a variety of specifications, and the most suitable application is selected from a variety of specifications, so that the advantages of steel pipe piles can be fully utilized to meet the safety and economic requirements of the project.
2. Strong bearing capacity. Most of the steel pipe piles used in the current construction are low-carbon steel. The material has strong strength, tensile, and compressive properties, and after being processed into a steel pipe, it has a high level of bending resistance. It is suitable for application in the geological environment with strong bearing layer, so that its mechanical characteristics can be fully exerted.
3. It is easy to adjust the pile length and improve economic benefits. The conventional length of each steel pipe pile is 6 m, which is extended by welding. If the buried depth of the bearing layer changes, the steel pipe pile can be welded or cut according to the pile sinking situation. In addition, the part cut out from the steel pipe pile can also be used in welding other steel pipe piles, which avoids the waste of resources, and can also accurately control the design elevation of the pile top, which is beneficial to the construction.
4. The compaction of the soil is slight. Most of the steel pipe piles are of the open type, and the pipe wall of the steel pipe pile is thinner, which reduces the uplift of the surface soil and the compacted soil, and reduces the interference of the pile on the soil and surrounding facilities. In addition, steel pipe piles can also be used for intensive construction in small-area sites.
In conclusion
Steel pipe piles are commonly used components in bridge pile foundation construction. It has the advantages of high bearing capacity, flexible piling and fast construction speed. For complex terrain, steel pipe piles are more suitable for this environment.
