[Construction Example] Elementary School (Classroom): Floor Sunken Correction Work and Deflection Correction Work
Due to ground subsidence, the classroom floor has sagged! The floor subsidence was corrected in a short construction period of one day.
We would like to introduce a case of "sunken floor correction work and deflection correction work" conducted in an elementary school classroom in Tokyo. Due to ground subsidence, a maximum of 80mm of sinking occurred in the center of the floor, causing deflection. Concerns for safety and health rendered the classroom unusable. The areas of the classroom floor that had sunk were corrected to -10mm, moving from the outer edges toward the center. The deflection of the classroom floor was resolved, and the work was completed. 【Case Overview】 ■ Construction Area: 63m2 ■ Maximum Subsidence: 80mm ■ Construction Period: 1 day ■ Area: Tokyo *For more detailed information about the case, please refer to the related links.
