The present invention relates to a fixed pile. More specifically, a greenhouse film fixing rod is formed at both end portions of a film and installed in a longitudinal direction at both sides of the bottom of a greenhouse to prevent the greenhouse film from being flown by wind, and a fixing string for fixing an outer peripheral surface of the film is hung to secure the film to prevent the film from being flown by a strong wind and to prevent the film from being uprooted from ground. The invention comprises: a body (100); a tip end unit (110) formed to have a sharp cutting edge at a lower part of the body (100) to be easily embedded underground; an insertion fixing groove (120) for inserting a greenhouse film fixing rod (180) for supporting a film at one upper part of the body (110); a fixing hanging hole (130) protruding a tip end unit formed in a curved line; a string fixing hanging hole (140) formed in an elbow shape for securing the string by inserting a fixing string (190), which supports the film on an opposite side of the fixing hanging hole (130), into a string insertion hole (140a); and a circular striking plate (150) formed at an upper end of the body (100) so as to be easily struck by a hammer.
