s2, after the circular truncated cone (3) is adjusted to be horizontal, the anchor rod frame (7) is pressed into a working surface of a working place through the circular block (30), the anchor rod frame (7) stops being pressed down after the fixed block (1) is contacted with the ground, the rotating block (11) is driven to rotate, the rotating block (11) drives the vertical screw rod (10) to rotate, the vertical screw rod (10) rotates to drive the multilateral driving block (8) to move downwards relative to the anchor rod frame (7), the multilateral driving block (8) moves downwards to push the telescopic positioning rod (9) out of the anchor rod frame (7) through the pushing block (12) against the elastic force of the spring (13), the telescopic positioning rod (9) is inserted into the working surface, and the municipal engineering positioning rod device is fixed relative to a piling working surface;

s3, after the fixing is completed, any one hand wheel (34) of the three hand wheels (34) is rotated, any one hand wheel (34) of the three hand wheels (34) rotates to drive the threaded rod (15) matched with the hand wheel (34) to rotate, the rotation of any one threaded rod (15) of the three threaded rods (15) is matched with the toothed ring (20) through the rotating gear (19), the synchronous rotation of the three threaded rods (15) is achieved, therefore, the three fixing plates (2) are quickly adjusted, in the process of adjusting the fixing plates (2), the pile driving column (17) is arranged among the three fixing plates (2), and the guiding adjustment of the pile driving column (17) is completed;

s4, after guiding adjustment of the piling column (17) is completed, starting a driving motor (27), enabling the driving motor (27) to work to drive a driving gear (25) to rotate, enabling the driving gear (25) to rotate to drive a double-sided rack (28) to rise, enabling the driving gear (25) to be a half gear, enabling the driving gear (25) to lose lifting effect on the double-sided rack (28) after the driving gear (25) rotates for half a circle, enabling the double-sided rack (28) to freely fall under the action of gravity of a collision disc (26), and achieving piling operation of the piling column (17);

s5, after the piling operation is finished, the driving motor (27) is turned off, any one hand wheel (34) of the three hand wheels (34) is rotated reversely, the fixing plate (2) is far away from the piling column (17), then the vertical screw rod (10) is rotated reversely through the rotating block (11), the pushing action of the multi-edge driving block (8) on the telescopic positioning rod (9) is disabled, the telescopic positioning rod (9) is retracted into the anchor rod frame (7) under the action of the elastic force of the spring (13), the anchor rod frame (7) is pulled out from the operation surface, the municipal engineering device is moved to the next operation site, and the piling operation of the next round is started from new adjustment and installation.
