How to make screw pile

　　The processing level of the 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 the welding, whether there are sand holes, faulty welding, and the width of the welding, which all affect the future service life of the ground pile and the quality of the subsequent processing. Acid pickling is an important anti-corrosion root technology process, while the quality of the hot plating, such as the time of hot plating, the quality of the surface treatment, all affect the quality of the hot plating Quality of anti-corrosion treatment of ground piles. In general, spiral piles can be used for 40-80 years. The environment and application methods of the application process also affect the service life of the ground pile, such as the acid-base degree of the soil, whether the operation process is appropriate, and improper application, which will cause damage to the surface of the metal ground pile, damage to the metal protective layer, accelerate the corrosion of the metal ground pile, and reduce the service life. The environment and application method of the application process of the processing technology of the spiral ground pile also affect the service life of the ground pile, such as the acid-base degree of the soil, whether the operation process is appropriate or not, improper application will cause damage to the surface of the metal ground pile, damage to the metal protective layer, and accelerate the corrosion of the metal ground pile, In order to reduce the service life of the spiral ground pile, the qualified ground pile can be produced by blocking, deformation, welding, pickling, hot plating and other technical processes. Pickling and hot galvanizing are important anti-corrosion treatment processes, which directly affect the service life of the spiral ground pile.
