the adjusting rod (53), the end of the expansion joint (22) is rotatably provided with the adjusting rod (53), the bottom of the adjusting rod (53) extends into the lifting pipe (52), and the adjusting rod (53) is in threaded connection with the lifting pipe (52).
10. A pile core positioning method is characterized in that: the method is suitable for the pile core positioning device as set forth in claim 9, and includes the following steps:
a1: carrying the pile core positioning device to the end part of the engineering pile, and then manually snapping the telescopic arm (2) until the telescopic arm (2) is attached to the limiting plate (4), wherein the telescopic arm (2) horizontally extends along the radial direction of the positioning ring (1);
a2: the pull ring (33) is manually pulled, the telescopic arm (2) is unfolded under the cooperation of the traction rope (32) and the pull rope (24), then the position of the pile core is manually judged, and the pile core positioning device is placed in the position range;
a3: the pull ring (33) is loosened, the telescopic arm (2) automatically contracts under the action of the connecting spring (23) to realize preliminary positioning, and the corresponding adjusting rod (53) is rotated to adjust the levelness of the pile core positioning device under the deviation indication of the visible light emitted by the positioning cone (11) and the centering hole (42);
a4: the scales on the telescopic arms (2) are read, the positions of the positioning rings (1) are adjusted, so that the lengths of the two telescopic arms (2) on the same straight line are the same, accurate adjustment of pile core positioning is achieved, at the moment, the positions irradiated by visible light after passing through the centering holes (42) are marked, and the pile core positions are determined.
