four groups of vertical jacking oil cylinders (4) of the clamping mechanism (100) are symmetrically arranged at four corners between the lower end surface of an upper underframe (13) of the upper rack (1) and the upper end surface of the fine adjustment rack (523); the cylinder ends of the vertical jacking oil cylinders (4) are fixedly arranged on the lower end surface of the upper underframe (13) respectively, and the piston rod ends of the vertical jacking oil cylinders (4) are connected to the upper end surface of the fine adjustment rack (523) in a spherical hinge mode respectively, so that the upper rack (1) can move downwards when the four groups of vertical jacking oil cylinders (4) contract simultaneously;

the hydraulic system (6) is positioned at one side of the lower rack (8) and respectively conveys hydraulic oil to each working hydraulic oil cylinder through a hydraulic pump station, a collecting valve, a hydraulic lock, a safety valve and a hydraulic pipeline so as to meet each operation procedure of the crawler travelling mechanism (110), the hoisting mechanism (120) and the clamping mechanism (100);

the electric welding machine bin (7) is positioned on the other side of the lower rack (8), is provided with a gas storage bottle, a wire feeding device and a carbon dioxide gas protection automatic welding machine, and is used for welding and lengthening various implanted steel pipe pile bodies to meet the length requirement of the implanted piles;

a plurality of strain gauges (1901) of stake body monitoring system (190) set up on its stake body outer peripheral face along precast pile body axial direction at a certain distance interval, through pencil (1902) parallel connection to monitor (1903), can monitor the precast hole overall process of precast pile body implantation, guarantee the straightness requirement that hangs down of planting a stake.

2. The pile-planting machine with monitoring function according to claim 1, wherein the bevel angle of the back of the clamping wedge (15) and the bevel angle of the dovetail groove (121) are both α -5-10 °.

3. The pile-planting machine with monitoring function according to claim 1, characterized in that the dovetail grooves (121) on the inner wall of the clamping ring (12) are arranged into 3, 4 or 6, and the clamping wedge blocks (15) are also arranged into 3, 4 or 6 corresponding to the clamping wedge blocks.

4. The pile-planting machine with monitoring function as claimed in claim 1, wherein the cushion block (153) can adapt to pile-planting construction of various pile diameters.

5. The pile planting machine with the monitoring function according to claim 1, wherein the fine adjustment frame (523) of the fine adjustment mechanism (52) has fine adjustment strokes of 0-150 mm in the longitudinal and transverse directions and the center of the inner circular hole (524).
