Abstract
A concrete wall body pile comprises a long-cylinder-shaped concrete pile body. A vertical central hole which penetrates through the concrete pile body up and down is formed in the center of the concrete pipe body. The shape of the outer portion of the cross section of the concrete pile body is rectangle. The length of each of four edges of the rectangle is 300-800mm. A pair of symmetrical lateral walls of the concrete pile body is respectively provided with a plurality of strip-shaped grooves vertically. A plurality of vertical through holes which are arranged around the vertical central hole are vertically formed in the concrete pile body. Main ribs which are made of deformed steel bars or pre-stress steel stranded wires are installed inside the vertical through holes. Concrete is filled in gaps between the main ribs and the vertical through holes. When two concrete wall body piles abut tightly against each other, the strip-shaped grooves of one wall body pile are in butt joint with the strip-shaped grooves of the other wall body pile one to one to form a plurality of holes, and concrete which bounds the two concrete wall body piles together is filled inside the holes, and therefore the connection between the pile bodies is quick and firm.
