PROBLEM TO BE SOLVED: To provide a civil engineering pile body low in cost, volume, and weight, easily transportable, providing no rust, and high in strength and safety. SOLUTION: In this synthetic resin pipe body for civil engineering, plate-like bodies 5a and 5b having lower edges 6a and 6b formed in inclined faces raising toward tips and upper edges 7a and 7b connected to the upper end 8 or a part slightly lower than the upper end 8 of a bar-like part 2 are arranged continuously with the upper part of the bar-like part 2 on both sides of the bar-like part 2 along the longitudinal direction of the bar-like part 2 to form wing-like parts 3a and 3b. A conical body having a width in cross section increasing toward an upper part is arranged continuously with a lower part to form an arrow-like part 4. COPYRIGHT: (C)2004,JPO
