Description

Technical Field

[0001] The utility model belongs to the field of road engineering construction, and particularly relates to a blocking structure for a non-excavation grouting hole in a road. Background Art

[0002] After a period of use, roads will develop cracks, subsidence, slurry, mud pumping and other road diseases, which need to be repaired. At present, non-excavation grouting reinforcement technology is usually used to repair roads. During the repair, several grouting holes are first drilled on the road surface, and then specific materials are injected into the grouting holes to fill the gaps, strengthen the roadbed, and improve the bearing capacity of the road surface. Drilling grouting holes on the road surface requires a certain construction period. The construction team often injects specific materials into the grouting holes on the second or even third working day. At this time, the grouting holes need to be blocked to prevent rainwater or debris from entering the grouting holes, so as to avoid affecting the road environment and the quality and effect of grouting construction.

[0003] In the prior art, there is a waterproof plugging structure for a through-wall screw, and its patent application number is: 202022322470.3; application date: 2020.10.19; its structure includes a concrete wall and a through-wall screw, the end of the through-wall screw is cut flat with the wall surface of the concrete wall, the end of the through-wall screw is cut deeply into the concrete wall and forms a hole on the wall surface of the concrete wall outside the screw head of the through-wall screw, and the screw head is evenly coated with an anti-rust paint layer. This structure can waterproof and plug the screw of the wall, but its disadvantage is that it cannot be used to plug the road grouting hole, which will cause rainwater or debris to enter the road grouting hole, affecting the quality of the grouting construction.

[0006] The utility model is used to quickly and effectively block the grouting holes of roads. When in use, the isolation membrane is first embedded in the grouting hole, and the outer periphery of the isolation membrane is fixed on the road layer at the outer periphery of the grouting hole. Then the waterproof foam filling material is injected into the grouting hole. The waterproof foam filling material makes the isolation membrane fit on the hole wall of the corresponding grouting hole, completing the rapid blocking of the grouting hole. When the grouting hole needs to be grouted, the isolation membrane and the waterproof foam filling material are taken out of the grouting hole, and the removal is also very convenient.
