Embodiment 1
[0073] See Figure 2 to Figure 4 Shown, a kind of concrete crack repair and anti-seepage processing method, this method comprises the following steps:
[0074] (1) Clean up: use tools such as spatulas, chisels to clean up the base surface of the concrete structure 1 in the area where the crack 31 (i.e. the gap in the concrete structure) is located, find out the leaking crack 31, and check the leaking situation of the crack 31 in detail, Determine and mark the grouting location;
[0075] (2) Grooving: use a cutting machine to grooving with the crack 31 as the center, and drill a "U"-shaped groove (large inside and small outside) with a width of 3 cm to 4 cm and a depth of 5 cm to 6 cm at the crack 31 ;
[0076] (3) Sealing the slots and burying the grouting nozzle 4: use micro-expansion quick-setting plugging material and water to mix into cement at a weight ratio of 1:0.3, and fix the grouting nozzle 4 at the preset crack 31 in the groove And seal and compact the rest of th...
Embodiment 2
[0081] See Figure 5 to Figure 7 Shown, a kind of concrete structure cold seam repair and anti-seepage treatment method, this method comprises the following steps:
[0082] (1) Cleaning: Clean up the base surface of the concrete structure 1 in the area where the structural cold joint 32 (that is, the gap in the concrete structure) is located with a spatula, chisel, etc., find out the leaking cold joint 32, and check the seepage of the cold joint 32 in detail. In case of leakage, determine and mark the grouting position;
[0083] (2) Grooving: With the cold seam 32 as the center, use a cutting machine to perform groove processing, and the cold seam 32 of the structure will be drilled into a "U"-shaped groove with a width of 3cm to 4cm and a depth of 5cm to 6cm (inner large foreign small);
[0084] (3) Sealing the slots and burying the grouting nozzle 4: use the micro-expansion quick-setting plugging material and water at a weight ratio of 1:0.3 to mix it into a cement shape, ...
