Analysis of the characteristics of steel pipe piles
Update time:2021-12-11

1. There are many specifications and a variety of options. At this stage, the finalized production of steel pipe piles on the market has a variety of specifications. Choose suitable applications from a variety of specifications, so that the advantages of steel pipe piles can be fully utilized to meet the safety of the project , Economic requirements.

2. Strong bearing capacity, the steel pipe piles used in project construction at this stage are mostly low-carbon steel. The material is strong in strength, tension, compression and other aspects, and after being processed into steel pipes, it has a higher level of bending resistance, and it is suitable for application in geological environments with strong bearing layers. , So that its force characteristics can be fully utilized.

3. It is easy to adjust the pile length and improve economic efficiency. The conventional length of each section of steel pipe pile is 6 m, which is connected by welding. If the buried depth of the bearing layer changes, the steel pipe pile can be combined with the pile sinking Welding or cutting treatment. In addition, the cut out part of 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 soil squeezing situation is slight. Most of the steel pipe piles are of open type, and the pipe wall of the steel pipe piles is thin, which reduces the uplift of the topsoil and the squeezed soil, and reduces the interference of the pressed piles on the soil and surrounding facilities. In addition, steel pipe piles can also be intensively constructed in a small area.
