On the one hand, traditional pile foundation construction techniques are inconvenient and ineffective in polar environments, affecting the use of prefabricated buildings. On the other hand, in polar environments, geological structures such as ice and snow and ice sheets are widely distributed, and how to effectively connect them with pile foundations has become a key technical challenge in pile foundation construction in polar environments.

[0021] Example 1:

[0022] Please see Figures 1-4 As shown, this utility model provides a prefabricated building pile foundation for polar environments, including pile bodies 1, the number of which is four. A pile platform 7 is movably connected between the tops of the four pile bodies 1. A stabilizing frame 2 is fixedly connected to the outer surface of the pile body 1. A heat-conducting pipe 15 is fixedly connected to the inner cavity of the pile body 1. A protective plug 10 is movably connected between the middle end of the top of the pile body 1 and the upper end of the inner cavity of the heat-conducting pipe 15. A liquid extraction pipe 11 is fixedly connected to the middle end of the protective plug 10. A heating strip 12 is wrapped around the surface of the liquid extraction pipe 11. An installation stud 8 is fixedly connected to the top of the pile body 1. The surface of the pile platform 7 is movably connected to the surface of the installation stud 8. An installation nut 9 is threadedly connected to the upper end of the installation stud 8.

[0023] In this technical solution, the heating belt 12 and heat-conducting pipe 15 can heat and melt the ice or ice cap around the pile body 1 during the overall installation process. During the subsequent refreezing of the melted ice or ice cap, the spiral stabilizing frame 2 can be redistributed and combined with the ice and snow geological structure around the pile body 1, thereby greatly improving the stability of the pile body 1. The installation studs 8 and installation nuts 9 facilitate the locking and fixing of the pile platform 7 and the pile body 1, so as to realize the rapid assembly of the pile platform 7 and the pile body 1.

[0024] Example 2:

[0025] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, a delivery pump 6 is fixedly installed at the upper end of the extraction pipe 11, a support base 5 is fixedly installed at the bottom of the delivery pump 6, the bottom of the support base 5 is placed on the top of the pile platform 7, an output pipe 3 is fixedly installed at the output end of the delivery pump 6, a flange 4 is fixedly connected to the back of the output pipe 3, a sealing gasket is fixedly connected to the back of the flange 4, a limit clamp 14 is fixedly installed between the outer surface of the extraction pipe 11 and the surface of the heating belt 12, there are five limit clamps 14, and the distance between two adjacent limit clamps 14 is equal, a rubber sleeve 13 is sleeved on the upper end of the heating belt 12, the surface of the rubber sleeve 13 is fixedly connected to the left end of the protective plug 10, and the shape of the stabilizing frame 2 is spiral.

[0026] In this technical solution, the installation of the delivery pump 6 and the output pipe 3 facilitates the extraction of the heat-conducting liquid inside the heat-conducting pipe 15 through the extraction pipe 11 after the pile body 1 reaches the elevation, and then transports it to the recovery pipeline through the output pipe 3, thereby achieving the effect of recycling the heat-conducting liquid.

[0027] The working principle of this utility model is as follows: After the pile hole is drilled and shaped, a horizontal force is applied to the pile body 1 using a pile driver, so that the pile body 1 can rotate downward along the surface of the pile hole to the designed elevation. At this time, under the action of the heating belt 12, the heat-conducting liquid added inside the heat-conducting pipe 15 can be heated, so that the temperature of the heat-conducting liquid rises rapidly and is conducted to the surrounding area of ​​the pile body 1 through the heat-conducting pipe 15, so that the ice and snow or ice cap around the pile body 1 melts. During the subsequent process of stopping heating, the melted ice and snow or ice cap can be re-frozen, and the spiral stable frame 2 can be redistributed and combined with the ice and snow geological structure around the pile body 1, thereby greatly improving the stability of the pile body 1. Then, personnel can lock and fix the pile platform 7 and the pile body 1 by installing studs 8 and nuts 9, thereby completing the installation of the prefabricated building.
