An apparatus measures a supporting force of ferroconcrete piles by means
of a bi-directional front end oil pressure loading apparatus using a high
pressure loading system capable of measuring a supporting force, a
sinking amount and an axis load distribution on the ferroconcrete piles.
The apparatus comprises: a steel plate having a predetermined thickness
and diameter and including upper and lower discs having penetration holes
through which concrete passes; a fixing member for separating the discs
from each other by a predetermined distance; a high oil pressure cylinder
for producing an oil pressure force; an oil cylinder inflation
displacement measuring sensor for measuring a displacement; an upper
displacement measuring rod coupled to the upper disc for measuring a
displacement of the upper disc; a lower displacement measuring rod
coupled to the upper disc for measuring a displacement of the lower disc;
an axis load transition measuring instrument including a tremie induction
tube coupled to the upper disc for guiding concrete to the penetration
holes; iron elements coupled to the upper disc; a load sensor for
measuring ground abrasion; and a sensor line for transferring a signal
and current to the load sensor. A corresponding method is disclosed.
