[0037] Working principle:

[0038] The first step is that when the municipal sewage well grouting device is used, the manhole cover of the sewage well body 1 that needs to be repaired is opened, and then the bearing column 11 is placed in the sewage well body 1, and then the bearing column 11 is rotated. The bearing column 11 rotates to drive the bearing block 15, and the bearing block 15 is forced to drive the sleeve 2, and the sleeve 2 is forced to drive the threaded sleeve rod 21, and the threaded sleeve rod 21 is forced to drive the rubber sleeve 34. When the rubber sleeve 34 is facing the damaged position, the bearing column 11 is stopped from rotating, and then the servo motor 13 is started. The output shaft of the servo motor 13 drives the threaded rod 14 to rotate, and the threaded rod 14 is forced to rotate in the bearing block 15. The threaded rotation of the threaded rod 14 adjusts the height of the bearing block 15 downward. When the bearing block 15 drives the rubber sleeve 34 to reach the damaged point, the servo motor 13 is turned off. While the servo motor 13 is started, the two rockers 19 are rotated respectively to keep the rubber sleeve 34 and the rubber support block 36 from contacting the inner wall of the sewage well body 1. When the rubber sleeve 34 reaches one side of the damaged position, it continues to rotate. The two rocking arms 19 are moved, and the rocking arms 19 are forced to drive the gear 18 to rotate, and the gear 18 rotates to drive the rack 17, and the rack 17 is forced to drive the internal threaded gear 22 to rotate, and the internal threaded gear 22 rotates to drive the threaded sleeve rod 21, and the threaded sleeve rod 21 is forced to rotate by thread, and the threaded rotation of the threaded sleeve rod 21 drives the rubber support block 36, and the rubber support block 36 is forced to contact the inner wall of the sewage well body 1 and support and fix the bearing block 15, and the threaded rotation of the threaded sleeve rod 21 drives the rubber sleeve 34, and the rubber sleeve 34 is forced to contact the damaged point, and the repair cavity 35 covers the damaged point, and then the mud pump 3 is started, and the mud pump 3 pumps the filling concrete slurry into the repair cavity 35 to fill the damaged point. By designing the municipal sewage well grouting device as a sealed filling, when the inner wall of the sewage well is damaged, the damaged point of the inner wall of the sewage well covered with sewage can be repaired without affecting the use of the sewage well, thereby effectively improving the practicality of the municipal sewage well grouting device.

[0039] In the second step, when the municipal sewage well grouting device is used, when the rubber sleeve 34 is forced to contact the damaged point and the repair cavity 35 covers the damaged point, the mud pump 3 is started, and the mud pump 3 pumps the filling concrete into the delivery pipe 31, and the delivery pipe 31 guides the concrete into the delivery hose 33, and the delivery hose 33 guides the concrete into the repair cavity 35. Then, because the density of concrete is greater than the density of sewage, the residual sewage in the repair cavity 35 is discharged by the exhaust hose 32. By adding the exhaust hose 32 to the municipal sewage well grouting device, the sewage or air in the repair cavity 35 can be discharged during the maintenance work, thereby improving the applicability of the municipal sewage well grouting device for inspection and maintenance work.
