| titleOfInvention | Fracture unilateral plugging method |
| abstract | The invention provides a fracture unilateral plugging method, which comprises the following steps: s1, putting expansion pipes with corresponding sizes into the cracks, and enabling the expansion pipes to be opened after the expansion pipes reach the preset depth of the cracks; s2, throwing screen cloth and/or fiber clusters into the cracks; s3, pouring expanded mortar in the cracks; s4, pouring quick-drying mortar into the cracks; through the steps, the fracture is blocked from one side. By adopting the scheme, the reliable plugging of cracks which are deeply developed, have larger coverage and are communicated with each other from a single side can be realized. The screen cloth and the fiber clusters can further block smaller gaps, and the slurry waste is further reduced. The adopted expanded mortar can rapidly expand 10-200 times within 3-6 hours after reaching the plugging position, the expansion multiple of the expanded mortar is controlled by adjusting the pH value of the mixing water, and the rest of the mortar is super delayed coagulation mortar, so that the initial setting can be completed after the water absorption gel in the expanded mortar is expanded, thereby forming the preliminary plugging. |
