Steel pipe pile is a common component in the construction of bridge pile foundations. It has the advantages of high bearing capacity, flexible pile driving, and fast construction speed. For complex terrain, steel pipe pile is more suitable for this environment.

1. Type of steel pile

At present, there are three types of steel piles commonly used in engineering construction, which are steel pipe piles, shaped steel piles, and steel sheet piles.

1. Compared with other steel piles, steel pipe pile has its unique advantages in many aspects. For example, bending stiffness, single pile bearing capacity, and many other aspects.

2. Type I and type H steel piles belong to the more common section shapes of type I steel piles, which can be applied in the bearing capacity of horizontal and vertical loads.

3. Steel sheet pile has a variety of forms, and the shapes of the parent and child interface slots on both sides are different. After the first sheet pile is in place, the side notch of the previous sheet pile is taken as the driving position, so that multiple sheet piles can form a relatively complete sheet pile wall along the coast (or bank). In addition, a group of steel sheet piles can also be used as a perimeter survey, or as temporary retaining protection in the excavation of the foundation pit.

2. the characteristics of steel pipe pile analysis

1, various specifications, with a variety of choices, at the present stage in the market of steel pipe pile, typecast production has a variety of specifications, from a variety of specifications to select the most suitable application, so that the advantages of steel pipe pile can be given full play to meet the safety and economic requirements of the project.

2, the bearing capacity is strong, and the steel pipe pile used in the present stage of engineering construction is mostly low-carbon steel. The material in the strength, tensile, compressive, and other aspects of the ability is strong, and after processing the formation of steel pipe, its bending level is high, suitable for the bearing layer is strong in the geological environment, so that its mechanical characteristics can be fully played.

3. Easy to adjust the pile length and improve economic benefits. The conventional length of each steel pipe pile is 6 m, which is lengthened by welding. If the buried depth of the bearing layer changes, the steel pipe pile can be welded or cut according to the situation of pile driving. In addition, the excised part of the steel pipe pile can also be used in welding other steel pipe piles to avoid the waste of resources, and the design elevation of the pile top can be accurately controlled, which is conducive to the construction.

4, the situation of soil extrusion is slight, most of the steel pipe pile is an open type, and the pipe wall of the steel pipe pile is thin, reducing the uplift of the topsoil and soil extrusion, reducing the interference of the pile on the soil and surrounding facilities, and the steel pipe pile can also take intensive construction in a small area of the site.

Therefore, the classification of steel piles and the characteristics of steel pipe piles explained above can make everyone better understand and use reason, so as to improve the quality of construction.
