Example 1

Referring to fig. 1 and 2, the present embodiment provides a spiral ground pile 100, which includes a ground pile body coated with a fused epoxy powder coating, the ground pile body includes a pile body 101 and a spiral blade 102 disposed on the pile body 101, and one end of the pile body 101 is conical.

In this embodiment, the pile 101 is a cylinder with a diameter of

Of course, in actual production, the pile body 101 can also be adopted

180mm，

And the like of different diameters. One end of the pile body 101 is conical, so that the spiral ground pile 100 can be conveniently screwed into the soil. 5 helical blades 102 are welded on the pile body 101, and the 5 helical blades 102 are sequentially arranged along the axial direction of the pile body 101; the distance between every two adjacent helical blades 102 gradually increases from the tip end to the tail end. If the distance between the first helical blade 102 and the second helical blade 102 is 30cm, the distance between the second helical blade 102 and the third helical blade 102 is 40cm, and the distance between the third helical blade 102 and the fourth helical blade 102 is 30cmThe distance is 50cm, and the distance between the fourth helical blade 102 and the fifth helical blade 102 is 60 cm. This arrangement may improve the ground drilling ability and pile sinking efficiency of the screw pile 100. Of course, the number of the helical blades 102 may be increased or decreased appropriately according to the geological soil layer.

The outer side wall of the pile body 101 is coated with a fused bonding epoxy powder coating with the thickness of 300um, and certainly, for some soils with good geological conditions, the coating thickness can be adjusted to 200um, so that the manufacturing cost is reduced. For some soils with very harsh geological conditions, such as soils with relatively high ph, the coating thickness can be adjusted to 500um, which, although increasing the manufacturing cost, can meet the expected service life. The fusion bonding of the epoxy powder coating enables the whole spiral ground pile 100 to have good wear resistance and corrosion resistance, and the service life of the spiral ground pile 100 is prolonged.

In some other embodiments, the helical blade 102 and the pile body 101 may be integrally formed by casting, which not only reduces the production processes and improves the production efficiency. More importantly, when the pile is drilled into the soil layer, the spiral pile 100 can be prevented from being broken due to welding seams generated by welding.

Example 2

This example provides a process for producing a screw pile 100 with a fusion bonded epoxy powder coating:

the method comprises the following steps:

first, galvanizing treatment: pickling the spiral ground pile 100, and then carrying out hot-dip galvanizing treatment;

secondly, sand blasting: the spiral ground pile 100 is subjected to sand blasting treatment by using a sand blasting furnace, so that the surface of the spiral ground pile is free of oil, water, rust and dirt, and has certain smoothness, roughness and activation degree. After sand blasting, the sand dust attached to the surface of the spiral ground pile 100 is blown off by purified air, the cleanliness reaches Sa2.5 grade, and the roughness reaches 80um to 100um, so that the adhesive force of epoxy powder can be improved.

Thirdly, preheating treatment: the spiral ground pile 100 is sent into a heating furnace, the temperature of the spiral ground pile 100 reaches 215-270 ℃, and the preheating time is 20-30 min;

fourthly, spraying epoxy powder: spraying, melting and combining epoxy powder on the surface of the preheated spiral ground pile 100 by using an electrostatic gun;

fifthly, curing the coating: the ground pile body after being sprayed is sent into a heating furnace for curing treatment, and if the curing temperature is too high, energy is wasted; if the curing temperature is too low, the leveling property and heat resistance of the coating layer are poor. Therefore, when the temperature of the spiral ground pile 100 reaches 230-260 ℃ and the preheating time is 20-30 min, the coating is more uniform and complete and does not have pinholes.
