Regarding cracks reserved in the ground surface
Thread Content
What is the main function of the cracks reserved during the ground construction process? Since I’m not majoring in civil engineering, I know relatively little about this area!
In my opinion, the cracks reserved during the ground construction process are intended to prevent the ground materials from breaking or deforming due to thermal stress (expansion and contraction caused by heat). In short, the cracks reserved during the construction process are intended to reduce the damage caused by thermal stress.
Bro, that crack is officially called a \"expansion joint,\" and the principle behind it was explained upstairs: \"thermal expansion and contraction.\"
The term \"reserved crack\" is incorrect; it should be a expansion joint
