[0030] Working mode: First, the reinforcement cage 6 and the sleeve 7 have been set on the ground, at this time, the two monitoring assemblies of the monitoring unit 2 are assembled on the outer circumferential side of the guide pipe 5 on the ground, then they are lowered for a distance, then the two guiding assemblies of the guiding unit 1 are assembled on the ground, the cable 4 is wound around the capstan 14 in the manner as shown in the figure, and then is installed to the double-drum hoist 3, the specific installation manner is not described herein, and the conventional hoist cable installation manner can be used.

[0032] During the monitoring, the monitor 28 can move along the arc direction of a circular arc through the arc-shaped guide rail 25, and the orientation of the monitor 28 can be deflected along the radial direction of the circle drawn with any point on the guide pipe axis through the first rotating motor 26, and the monitor 28 can be moved to the joint of the two second semicircular arc plates 21 through the second rotating motor 27, so that the monitoring direction is directed to the area which is not covered by the projection of the arc-shaped guide rail 25 on the pouring surface of the concrete.

[0033] After the monitoring of the concrete of one pile foundation is completed, the monitoring unit 2 has also been lifted to the ground, and the guiding unit 1 and the monitoring unit 2 are disassembled.
