9. A construction method for a rapid leak-stopping grouting device for bored piles on a riprap dike in a sea area, characterized in that: The rapid leak-stopping grouting device for bored piles on riprap dikes in marine areas, as described in any one of claims 1-8, further includes the following steps: Step 1: Move the mobile vehicle (1) to a suitable location near the construction site of the bored pile, ensuring that the site is flat and the vehicle is parked securely to avoid displacement during subsequent operations; Step 2: Start the first motor (203) and adjust the height of the grouting mechanism (3) to a suitable height that is slightly higher than the opening of the grouting pile; Step 3: Using the self-moving function of the mobile vehicle (1), move the device to the top of the borehole of the bored pile to be processed, so that the grout stop bucket (305) is aligned with the bored pile hole; Step 4: Adjust the height of the lifting plate (205), start the second motor (301), and slowly lower the grout stopping mechanism (3). The rotation of the screw rod (304) makes it easier for the grout stopping mechanism (3) to descend. The detector (303) monitors the depth and diameter changes in the grouting pile hole below and whether there are obvious grout leakage points in real time, and transmits the data to the control system. Step 5: When the detector (303) detects the leak location and approaches the wall of the grouting pile hole, control the grout stop bucket (305) to be lowered to the leak location, inflate the air bag (309) with air, and the air bag (309) expands and opens the adjustable sealing sleeve (310) to seal the leak location; Step 6: After sealing is completed, the pre-prepared grouting material is delivered into the grouting tank (305) through the delivery pipe (311), and the nozzle (307) sprays the grouting material onto the grout leakage part of the grouting pile hole wall to achieve precise sealing of the grout leakage point; Step 7: When the leakage of grout is detected to be under effective control, stop the operation of the second motor (301), stop the material being fed into the grout stop bucket (305), slowly lift the lifting plate (205), drive the grout stop mechanism (3) to move upward, and remove it from the grouting pile hole.
