Concrete file drawing public law and the drawing which are laid in

摘要

The present invention relates to a concrete pile drawing method embedded in the ground. That is, the present invention comprises the steps of arranging the ground around the head of the concrete pile (1) embedded in the ground; The center of the discharge pipe (2) having a hollow portion 201 having an inner diameter larger than the outer diameter of the concrete pile (1) coincides with the center of the concrete pile (1), the concrete pile (1) embedded in the ground discharge pipe ( Embedding the discharge pipe 2 in the ground by the entire length of the concrete pile 1 so as to be inserted into the hollow portion 201 of 2); Connecting a drawing hole (3) to the head of the concrete pile (1) exposed to the ground; By connecting the drawing port (3) with the crane to pull up the drawing port (3) to extract the concrete pile (1) from the ground, the concrete pile embedded in the ground quickly and easily without excavation of the surrounding ground As it can be extracted, not only can greatly reduce the air due to the concrete pile removal construction, there is an advantage that can significantly reduce the construction cost by minimizing the input of equipment and manpower according to the concrete pile removal.
