[Construction Case] Ground Support Strengthening Injection Work for a Pool at a Certain Embassy

Introduction of construction examples of pool ground support reinforcement injection work.

The RC pool has a length of 25m and a depth of 2m to 4m, with uneven loading. It is believed to have settled due to water leakage from the circulation piping. Additionally, the ground around the leakage area has loosened, causing the southeast corner to settle locally and deform. The plan was to perform overall support strength enhancement injection to stabilize the entire subsoil of the pool from an uneven state to a stable, uniform state, rather than partial repairs to stop further settlement. As a result, the entire structure was lifted by several millimeters, and at the same time, the deformation and inclination were repaired, allowing it to be restored to its original condition. [Case Overview] ■ Location: Tokyo ■ Building Name: 25m ■ Structure and Scale: 25m pool (H2000 to H4000) ■ Foundation Structure: Slab foundation ■ Total Restoration Weight: Approximately 650t *For more details, please refer to the PDF document or feel free to contact us.
