ABSTRACT:
An anti-twist rod section (10) is disclosed which adapts a survey monument (38) at once to resist rotation and to conveniently accept hardware designed to engage cylindrical rods. The method of using the anti-twist rod section (10) in placing a survey monument (38) is also disclosed. The anti-twist rod section includes an elongated body (12) which may have at least one surface channel (18). At least one fin (20) joined to the body (20) at a junction (22) preferably within the channel (18). The junction (22) is adapted to allow the anti-twist rod section (10) to be driven into the ground with the fins (20) in place such that a portion of the fin (20) resists rotation of the anti-twist section. The junction (22) is also adapted to allow the fins (20) to be severed from the body (12) as they are bent tangentially away from the body (12) such that the anti-twist rod section (10) is left unimpeded by fins. The body of the anti-twist rod section (10) may then accept hardware designed to engage cylindrical rods. The anti-twist rod section (10) is commonly employed as an upper section in a survey monument (38) where, after having been driven into the ground, it can resist tampering and can enhance the self-tightening of cylindrical rod sections (42) during driving of the rod series.
