Ground screw anchor are generally cut, deformed, welded, pickled, hot-dipped, and other processes to produce qualified piles. Among them, pickling and hot-dip galvanizing are important treatment processes that directly affect the service life of the screw piles.
The processing level of the pile directly determines the service life of the metal pile, such as the quality of the selected welded pipe, the quality level of welding, whether there are blisters, virtual welding, and the width of the welding. These all affect the future service life of the pile and the quality of subsequent processing. Pickling is an important foundation process, and the quality of hot-dip coating, such as the time of hot-dip coating, and the appearance of surface treatment, all affect the quality of pile treatment. Under normal circumstances, spiral piles can be used for 40-80 years. The environment and application method of the application process also affect the service life of the pile. For example, the acidity of the soil, whether the operation process is proper, or improper use will cause damage to the surface of the metal pile and damage the metal protective layer. Corrosion of metal piles is accelerated, reducing service life.
How to use spiral piles in messy terrain?
For the terrain, there should be many different terrains. How to deal with the messy terrain?
If it is a severe situation that the drilling tool cannot be lifted and released, and the impactor does not sound, now as long as the rated torque is added or auxiliary tools are used to assist in the improvement, the drilling tool is reversed, and then it is required to increase the drilling tool while air is being supplied. , Until the problem processing stops. During heavy drilling, first apply a little pressure, and then gradually increase the propulsion force until the normal working pressure is reached.
