ABSTRACT:
A pile forming system and method for forming a pile. The pile forming system comprises a top pile forming member, a bottom pile forming member, and an end plate assembled together to provide a complete pile form which can then be filled with concrete to form the pile. Additionally, the pile forming system incorporates a tip forming member which can be secured to one end of the pile form to form a sharp tip at one end of the pile facilitating driving the pile into a subsurface. Additional pairs of top and bottom pile forming members may be joined end to end to form longer piles. After the desired pile form is assembled, concrete is poured or pumped into the pile form through openings on the top surface of the pile form. Preferably, reinforcement bars or rebars which are coated with a non-permeable coating to prevent rust are placed in the pile form before the pouring of the concrete. Pipes or tube inserts are also preferably inserted through opposite side openings on the pile forming members to serves as blockouts for various attachments. After the concrete cures, the forms are disassembled and the resulting pile released from the forming members.
