[0031] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0032] The present application will now be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0033] like Figure 1 As shown, the first exemplary embodiment of this application provides a basement repair structure, which includes a basement slab structure 1, an exterior wall 2, a corner groove 3, and a corner waterproofing structure 4. The exterior wall 2 is connected to the top of the base slab structure 1, and the junction of the inner wall at the base of the exterior wall 2 and the inner wall at the top of the base slab structure 1 is a corner. The corner groove 3 is formed in the corner and connects to the junction crack 5 between the base of the exterior wall 2 and the top of the base slab structure 1. The junction crack 5 extends at least from the interior of the exterior wall 2 to the corner. The corner waterproofing structure 4 fills the corner groove 3 and the junction crack 5, thereby sealing the corner groove 3 and the junction crack 5.

[0034] Therefore, the basement repair structure of this exemplary embodiment provides a corner groove 3 at the corner where the inner wall of the base of the exterior wall 2 meets the base slab structure 1, and fills the corner waterproof structure 4 in the corner groove 3, so that the junction crack 5 between the exterior wall 2 and the base slab structure 1 can be filled, thereby achieving the effect of repairing the wall base and effectively preventing groundwater from seeping into the room from the wall base.

[0035] In this embodiment, the groove width of the internal corner groove 3 can be 190mm to 210mm. If there is an integral surface layer such as a pad or leveling layer above the base plate structure 1, the base plate water-stop groove can be chiseled out at the position of the inner wall near the root of the outer wall 2, so that the base plate structure 1 is exposed. Then, the internal corner groove 3 is chiseled out between the root of the outer wall 2 and the base plate structure 1, so that the internal corner groove 3 effectively connects the junction crack 5 and improves the leak-stopping effect.

[0036] In an alternative and preferred embodiment, the corner waterproof structure 4 comprises a first grouting nozzle and a first filling grout, for example, a water-based polyurethane grouting material, which is arranged against the groove bottom of the corner groove 3 so that the grouting nozzle of the first grouting nozzle can be aligned with the interface crack 5 in the root of the outer wall 2 to communicate with the interface crack 5. By using the first grouting nozzle, the first filling grout can be injected into the interface crack 5, and after the interface crack 5 is filled, the first filling grout can continue to be filled in the first grouting nozzle.

[0037] In this embodiment, the corner groove 3 can be formed as a V-shaped groove so that the groove bottom can be effectively aligned and communicated with the interface crack 5. Accordingly, the first grouting nozzle is formed as a V-shaped grouting nozzle. The V-shaped grouting nozzle can be integrally nested in the V-shaped groove, and in particular during the grouting process, it can effectively guide the first filling grout into the interface crack 5.

[0038] If the depth of the corner groove 3 is large, after the first filling grout is filled in the first grouting nozzle, a leak stopper can be used to cover the first grouting nozzle, and then the entire corner groove 3 is filled to form a leak stop layer, so that the corner waterproof structure 4 can completely block the interface crack 5 and the corner groove 3, effectively preventing leakage at the root of the outer wall 2.

[0039] In Figure 1 In the embodiment shown, the outer side of the corner waterproof structure 4 is formed as a chamfered portion. In other words, when filling the corner groove 3 with materials such as leak stoppers, the leak stop layer can be shaped as a chamfer so that the leak stop layer smoothly transitions with the inner wall surface of the outer wall 2 and the top surface of the floor structure 1, respectively, to facilitate subsequent brushing of waterproof paint on the inner wall surface of the outer wall 2 and the top surface of the floor structure 1, so that the waterproof paint layer can be flat.

[0040] In an alternative and preferred embodiment, referring to Figure 1 , the basement repair structure further comprises a wall water stop groove 6 and a wall waterproof structure 7, wherein the wall water stop groove 6 is formed at the cold joint position of the inner wall of the outer wall 2 and communicates with the wall body crack 8 in the outer wall 2, and the wall waterproof structure 7 is filled in the wall water stop groove 6 and the wall body crack 8. Specifically, the groove width of the wall water stop groove 6 can be 18mm to 22mm, and is arranged along the extension direction of the cold joint of the inner wall. The wall waterproof structure 7 can comprise a second grouting nozzle and second and third filling grouts of different materials, wherein the second grouting nozzle is arranged at the groove bottom of the wall water stop groove 6, and its grouting nozzle is aligned and communicated with the wall body crack 8, and the second and third filling grouts are both filled in the second grouting nozzle and the wall body crack 8, so that the wall waterproof structure 7 can effectively block the wall body crack 8.

[0041] In the present embodiment, the second and third filling grouts are water-based and modified filling grouts respectively, and the second filling grout is injected first and then the third filling grout is injected. The water-based filling grout can be a water-based polyurethane grout, which can react and solidify instantly with water as a cross-linking agent after being injected into the wall cracks 8, and its volume expands rapidly during the process, thereby achieving the effect of closing and plugging the wall cracks 8. The modified filling grout can be a modified epoxy grout, which has good fluidity and can flow into various gaps of the injected part, and then solidify at room temperature. The solidification process involves the reaction of epoxy groups with hardening agents to form a three-dimensional cross-linked network, thereby further sealing the wall cracks 8 and improving the overall structural strength of the wall waterproof structure 7.

[0042] Further, the wall waterproof structure 7 further comprises a water stop rod and a sealing layer. The water stop rod can be a rubber water stop rod, which has good elasticity, wear resistance, aging resistance and tear resistance. By filling the water stop rod in the wall water stop groove 6 and covering the second grouting nozzle, the wall water stop groove 6 can be prevented from deforming. The sealing layer can be a sealant layer, which covers the water stop rod and fills the entire wall water stop groove 6, so that the water stop rod can be fixed in the wall water stop groove 6, thereby strengthening the overall structure of the wall waterproof structure 7, improving the waterproof performance, and making the outer side of the high wall waterproof structure 7 flush with the inner wall of the outer wall 2.

[0043] In an alternative and preferred embodiment, with reference to Figure 1 The basement repair structure further comprises a waterproof coating layer 9, which at least covers the outer side of the inside corner waterproof structure 4, thereby further enhancing the waterproof and anti-seepage effect of the intersection crack 5 and the overall inside corner part.

[0044] Further, the waterproof coating layer 9 covering the inside corner waterproof structure 4 can also extend to cover the entire inner wall of the outer wall 2, so that the waterproof coating layer 9 can cover the wall waterproof structure 7 on the inner wall of the outer wall 2, thereby further improving the waterproof and anti-seepage effect of the wall.

[0045] In some embodiments, the floor structure 1 comprises a floor body 101 and a floor repair layer 102 covering the inside corner waterproof structure 4. The floor repair layer 102 is a repair layer for filling the floor water stop groove drilled in the floor body 101, and the floor repair layer 102 can be a micro-expansion concrete layer. Thus, in the present embodiment, the waterproof coating layer 9 covering the inside corner waterproof structure 4 can also be filled in the gap between the floor body 101 and the floor repair layer 102, effectively preventing the floor repair layer 102 from leaking.

[0046] In the embodiment, the layer of the bottom plate repairing layer 102 is arranged flush with the top surface of the bottom plate body 101, so as to ensure the appearance of the basement floor.
