Problems solved by technology

Most of the existing crack plugging methods are directly opening grouting holes on the cracks, pouring slurry into the cracks through the grouting holes, and sealing the cracks after the slurry is solidified. There will also be secondary leakage, and the plugging effect is not ideal, so it needs to be plugged again, which increases the maintenance cost

Embodiment 1

[0029] Embodiment 1: In this embodiment, the width of the crack is 3 mm, the length of the crack is 20 cm, and the depth is about 4 cm. According to the width, length and depth of the slit of the present embodiment, the length of the slit 2 is determined to be 22cm, the width of the slit 2 is 1.5cm, and the depth of the slit 2 is 1cm; each of the two sides of the slit needs to drill 3 obliques. Hole 5, the diameter of inclined hole 5 is 10mm.

[0030] S1: Clean the surface of the structural crack 1 of the structure, use a cutting machine to create a slot 2 on the surface of the structural crack 1, after the slotting is completed, remove the impurities in the slot 2, and place the pipe dragging mold in the slot 2 , and then pour the sealing material into the slot 2, and before the sealing material is completely solidified, the drag tube mold is pulled out, so that a grouting channel 4 is reserved in the leak-stopping layer 3, and the grouting channel 4 is connected with the St...

Embodiment 2

[0035] Embodiment 2: In this embodiment, the width of the crack is 5 mm, the length of the crack is 15 cm, and the depth is about 8 cm. According to the width, length and depth of the crack of this embodiment, the length of the groove 2 is determined to be 28cm, the width of the groove 2 is 3cm, and the depth of the groove 2 is 1cm; 2 oblique holes need to be drilled on both sides of the crack 5. The diameter of the inclined hole 5 is 8mm.

[0036] S1: Clean the surface of the structural crack 1 of the structure, use a cutting machine to create a slot 2 on the surface of the structural crack 1, after the slotting is completed, remove the impurities in the slot 2, and place the pipe dragging mold in the slot 2 , and then pour the sealing material into the slot 2, and before the sealing material is completely solidified, the drag tube mold is pulled out, so that a grouting channel 4 is reserved in the leak-stopping layer 3, and the grouting channel 4 is connected with the Struc...

Abstract

The invention discloses a method for plugging and reinforcing structural cracks in structures, which comprises the following steps: S1: cleaning the surface of the structural cracks, opening a slot on the surface of the structural cracks, placing a drag pipe mold in the slots, Pouring the sealing grout in the groove to form a sealing layer, and before the sealing layer is solidified, the drag pipe mold is pulled out, so that a grouting channel is reserved in the cutting groove, and the grouting channel communicates with the structural crack ; S2: drill a plurality of inclined holes on at least one side of the structural crack length direction, at least one of the inclined holes runs through the structural crack; S3: install a grouting nozzle in the inclined hole, and pass the grouting nozzle to the inclined hole Pour epoxy resin grout into the center; S4: After the grouting is completed, after the epoxy resin grout is solidified, the surface of the structural crack is repaired and smoothed.

Description

technical field [0001] The invention belongs to the technical field of waterproof and plugging, and in particular relates to a method for plugging and reinforcing cracks in structures. Background technique [0002] After cracks appear in the structure, it is necessary to repair the cracks in time to prevent water leakage. Most of the existing crack plugging methods are directly opening grouting holes on the cracks, pouring slurry into the cracks through the grouting holes, and sealing the cracks after the slurry is solidified. There will also be secondary leakage, the plugging effect is not ideal, and the plugging process needs to be carried out again, which increases the maintenance cost. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned deficiencies in the prior art and provide a method for plugging and reinforcing structure cracks. The present invention drills oblique holes on both sides of the crack and opens a gro...
