Structural Cracks And Seepage

① Drill holes at an angle of 45 degrees to the left or right 2-5 cm from the lower part of the crack to the depth of half the thickness of the structure. Drill holes in sequence from low to high, with an appropriate hole spac- ing of 20-30 cm. After drilling to a high place, bury the water stop needle.Since the cracks in the general structure are irregular, special attention should be paid to the fact that the grouting needs to cross the crack surface when drilling, and the grouting will be effective.

② After the grouting water stop needle is placed, it is poured with chemical grouting material until the grout seeps out of the surface of the structure.

③ 48 hours after the grouting is completed, the grout- ing water stop needle can be removed.

Honeycomb Leaking

① At the range of the honeycomb, drill a hole every25-30 cm, the depth is generally suitable for the thickness of the structure, and then place the grouting water stop needle and rotate it to fix it.

② After the water-stop needle is placed, inject the chemical grouting material with a high-pressure grouting machine until it is found that the grouting material seeps out of the surface of the structure.

③ 48 hours after the grouting is completed, the grout. ing water stop needle can be removed.
