[Construction Case] Middle School (Gymnasium Floor): Settlement Correction and Void Filling Work
Due to the impact of the earthquake, the gymnasium floor has significantly sunk in a bowl shape! A case where the Upcon method was used to solve the problem.
We would like to introduce a case of "settlement correction and void filling work" carried out on the gymnasium floor of a junior high school in Fukushima Prefecture. Due to the effects of an earthquake, the floor had significantly sunk in a bowl shape from the outer edges towards the center, causing issues with the use of the gymnasium. The area that had sunk by a maximum of 108mm was corrected to within the planned value of -15mm, and it was confirmed using a CCD camera that the polyurethane resin was filled without any gaps, completing the work. [Case Overview] ■ Construction Area: 1,036m2 ■ Construction Period: 8 days ■ Maximum Settlement: 108mm ■ Area: Fukushima Prefecture *For more detailed information about the case, please refer to the related links.
