Embodiment 1
[0047] Such as figure 1 Shown, is a kind of pile foundation structure that reduces side frictional resistance, and it comprises pile body main body and outer sleeve 2, and lubricant 4, wherein,
[0048] The main body of the pile body adopts a preformed prefabricated pile 3, the top of the main body of the pile body is connected with the supporting platform, and the bottom of the main body of the pile body extends into the bearing layer to play a supporting role;
[0049] The outer sleeve 2 is sleeved on the periphery of the main body of the pile, and the soil layer on the side is separated from the main body of the pile, and the bottom ends of the outer sleeve 2 are extended into the bearing layer and fixed;
[0050] The gap between the main body of the pile body and the outer sleeve 2 is filled with a lubricant 4 for reducing the friction between the outer sleeve and the main body of the pile body,
[0051] The outer sleeve 2 and the prefabricated pile 3 are made of glass fi...
Embodiment 2
