Description

Technical Field

[0001] This invention relates to the field of crack repair technology, specifically a crack repair instrument for reinforced concrete eaves structures. Background Technology

[0002] A reinforced concrete eaves is a small cantilever structure, typically composed of an eaves gutter beam, an eaves gutter base slab, and side slabs. The eaves gutter base slab is a cantilever slab, and its stress characteristics are similar to those of a canopy slab, primarily bearing bending moments. When the eaves gutter side slabs are high, the influence of wind loads on the internal forces of the base slab must also be considered.

[0003] When existing reinforced concrete eaves develop cracks, cement grouting can be used for cracks wider than 0.5mm; for cracks narrower than 0.5mm, chemical grouting is recommended. However, when performing chemical grouting, it is difficult for workers to approach cracks at a distance. Workers need to use tools to repair the cracks from outside the wall, making the repair process more complicated and time-consuming. Summary of the Invention
