Description
Technical Field
The application relates to the field of tubular piles, in particular to a prefabricated tubular pile convenient to reuse.
Background
At present, when a building is built beside a soft soil foundation, the soft soil foundation needs to be reinforced, the pipe pile is driven into the soft soil foundation in a common reinforcing mode, and when another building needs to be built on the soft soil foundation later, the influence on the building foundation due to the existence of the pipe pile is avoided, so that the pipe pile needs to be pulled out from the soil layer.
In the related art, the tubular pile is pulled out mainly by a vibration pile pulling method, wherein the vibration pile pulling method mainly utilizes an excitation force generated by a vibrator to enable a pile body to generate high-frequency vibration, so that the connecting force between the pile body and soil is reduced, and the soil is pulled out under the action of a lifting force.
In view of the above-mentioned related technologies, the inventor believes that, on one hand, pile pulling by the vibration method has a relatively high noise and is affected by the surrounding environment to a certain extent, and on the other hand, the vibration pile pulling method requires additional vibration pile pulling equipment, which has certain requirements on the construction space around the pile body.
