Description

PILE CONSTRUCTION METHOD

The present invention relates to a file construction method, and more particularly, to a file construction method capable of ensuring a horizontal support force.

Generally, in the civil engineering foundation stage, construction is carried out to support a structure by inserting several files on the ground.

Concrete files represented by PHC, steel pipe files, and H beams are mainly used as the files used for such foundation work.
