Description

Sinking-preventing foundation pile Technical Field The invention relates to the technical field of foundation piles, in particular to an anti-sinking foundation pile. Background When large or high-rise buildings are built, foundation piles driven into the ground are often required to be used when the stratum strength is insufficient or a soft soil layer is encountered, so-called piling is commonly used, and the load of the upper-layer building is transferred to a soil bearing layer or a harder land so as to increase the safety and stability of the building structure. The traditional pile driving is that six quincuncial piles are driven together, then take this as the main body post, have many epitaxial branches around the main body post, after driving into earth with the main body post, form the stake hole, thereby utilize the friction of stake hole and main body post to fix the effect to the main body post, but because the pile of main body post, the earth is received the extrusion of main body post and is followed the outside removal of main body post, and earth is contacted with the main body post all the time, thereby make the friction of pile gradually increase along with the depth of driving of main body post, thereby be unfavorable for the pile driving.
