Description

Pile cutting device and basic pile cutting method accordingly

The present invention relates to a pile cutting apparatus and a basic pile cutting method according thereto.

Concrete pile construction is a construction method that secures the bearing capacity of the ground and structure by penetrating the concrete foundation pile manufactured using centrifugal force into the ground through the buried or type construction method, then crushing the upper part of the pile to a certain height and arranging the head.

The work process of the concrete foundation pile as described above can be divided into three types: the ground penetration of the pile using the buried/type method, the head cleaning of the upper part of the concrete pile, and the securing of the bearing capacity through the connection of the ground and the upper structure.

Here, the head cleaning of the upper part of the concrete pile is performed by cutting the upper part of the concrete pile to match the level of the foundation in the pile foundation construction after the concrete pile penetrates the ground.

When cutting the upper part of the concrete pile as described above, it is crushed using a crusher mounted on construction equipment (excavator, etc.), or a worker cuts directly with a cutter.

However, the conventional cutting method as described above has a problem in that the cut surface is not smooth when cutting using a crusher mounted on construction equipment (excavator, etc.), and safety accidents (cuts, etc.) There were problems such as safety accidents such as tripping and electric shock due to the rise of groundwater on the foundation surface of concrete piles, and poor leveling of the cut surface according to the work skill of the workers.
