ABSTRACT:
A cast-in-place concrete pile essentially consists of a lower concrete layer having fibers intermixed therein and an upper concrete layer having reinforcing elements. The lower portions of the reinforcing elements are embedded in the lower concrete layer to increase the bonding strength between the lower and upper concrete layers. The cast-in-place concrete pile of the present invention is constructed according to the following method. That is, an excavated hole is firstly formed in the ground. The reinforcing elements are placed at the upper side of the excavated hole, and then concrete including the fibers is cast into the excavated hole until the lower portions of the reinforcing elements are embedded in thus cast concrete, so that the lower concrete layer is formed. Continuously, concrete is cast onto the lower concrete layer in the excavated hole to form the upper concrete layer. Since thus constructed cast-in-place concrete pile is integrated in one-piece, it is expected that the concrete pile has high confidence and safety.
