Self reliance pile and Self reliance retaining wall construction method using the same

摘要

The present invention relates to a self-sustaining thumb pile and a method for building a self-sustaining earth retaining wall by using the self-sustaining thumb pile for allowing a thumb pile to be self-sustained by tension of a tensile material, in which it is possible to improve buildability as the settling end on the upper side of the tensile material can be adjusted in height even when there is a difference in insertion depth of the thumb pile. The self-sustaining thumb pile according to a preferred embodiment of the present invention includes a lower pile made of H-shaped steel; an upper pile made of an H-shaped steel and rigidly connected to the upper end of the lower pile and having an elongated through-hole and a fastening guide slot formed in the upper part; a tensile material cradle mounted on the upper pile to be slidable up and down along a cradle guide slot; a threaded steel bar for cradle positioning adjustment supported on the upper pile and screwed to the tie rod so as to adjust the height of the tie rod on the rotating operation direction; at least one locking nut screwed into the threaded steel rod for fixing the cradle to fix a height-adjusted position of the cradle-fixing member; and a tension member for self-standing of the pile which is fixed at the lower end side of the lower pile at one end with the other end tied to the tie rod through the tie rod through hole and then settled by tensioning on the tie rod side through the guide long hole of the tied rod of the tensile material.
