Processing technology of screw pile

　　Generally, the spiral ground pile can produce qualified spiral ground pile through cutting, deformation, welding, pickling, hot plating and other technological processes. Among them, pickling and hot galvanizing are important anti-corrosion treatment processes, which directly affect the service life of spiral ground pile.

　　The processing level of the spiral ground pile directly determines the service life of the metal ground pile, such as the quality of the selected welded pipe, the quality level of welding, whether there are sand holes, false welding, and the width of welding, all of which affect the future service life and the quality of subsequent processing of the spiral ground pile. Acid pickling is an important basic anti-corrosion process, while the quality of hot plating, such as the time of hot plating, and the quality of surface treatment, All of them affect the quality of anti-corrosion treatment of screw pile.

　　In general, the spiral pile can be used for 40-80 years. The environment and use method of the use process also affect the service life of the spiral ground pile, such as the acid-base degree of the soil, whether the operation process is proper, and improper use, which will lead to the damage of the metal ground pile surface, the damage of the metal protective layer, the acceleration of the corrosion of the metal ground pile, and the reduction of the service life.
