Characteristics of steel pipe piles

Compared with other steel piles, steel pipe piles have their own unique advantages in many aspects such as extension welding, single pile bearing capacity, bending stiffness, and penetration ability.
Steel pipe piles come in many forms, and the shapes of the interface grooves on both sides of the steel pipe pile are different. With the second board in place, use the notch on the side of the previous board as a driving location. In this way, multiple sheet piles can form a relatively complete sheet pile wall along the coast (or river bank). In addition, a set of steel pipe piles can also be used for enclosure or as temporary support protection during foundation pit excavation. Let me introduce to you the characteristics of steel pipe piles.

(1) There are many specifications and multiple options. At this stage, there are many specifications for the final production of steel pipe piles on the market. In terms of diameter, the maximum is 2500 mm and the minimum is 316 mm. In terms of wall thickness, the maximum is 25 mm and the minimum is 6.5 mm. During construction, the most appropriate application can be selected from various specifications based on actual stress conditions, so that the strength of the steel pipe pile can be fully utilized to meet the safety and economic requirements of the project.
(2) Strong carrying capacity. At this stage, most of the steel pipe piles used in project construction are low carbon steel. The material has strong shear strength, tensile strength and compressive strength. After being processed into a steel pipe, it has a high level of bending strength and is suitable for geological environments with strong load-bearing layers, so that its stress characteristics can be fully utilized. , to optimize the bearing capacity of a single pile, reduce the size of foundation piles, and reduce the total number of piles.

(3) It is easy to adjust the pile length and improve economic benefits. The conventional length of each section of the steel pipe pile is 6m and is connected by welding. In addition, the cut-out part of the steel pipe pile can also be used for the welding of other steel pipe piles, which avoids waste of resources and can accurately control the design elevation of the pile top, which is beneficial to construction operations.
(4) The soil squeezing situation is slight, most steel pipe piles are open, and the pipe walls of steel pipe piles are thin. During the pile pressing process, soil can enter the pile body, forming a soil plugging effect, reducing the surface soil, and the uplift of the squeezed soil reduces the interference of the pile pressing on the soil and surrounding facilities. In addition, steel pipe piles can also be used for more intensive construction in smaller areas.
