[Construction Case] Joban Expressway Nagareyama IC Restoration and Repair Work - Settlement Correction Work

Heisei 25 Fiscal Year Joban Expressway Nagareyama IC Restoration and Repair Work

The expressways that suffered tremendous damage due to the Great East Japan Earthquake. On the Tohoku Expressway, there were 347 km of damage, and on the Joban Expressway, 153 km, with collapses and uneven road surfaces occurring at four interchanges. Upcon is conducting corrections for the sinking of concrete slabs on roads and airport aprons. Full-scale restoration work began the year after the earthquake, and our technology, which allows for corrections without breaking existing slabs and within a short construction period, was adopted for the restoration work. This time, we will introduce a case of disaster recovery work for concrete pavement slabs at the Nagareyama tollgate, commissioned by East Nippon Expressway Company. Due to the sinking of the concrete pavement slabs, the water gradient could not be maintained, resulting in puddles forming in front of the ETC sensors. Every time a vehicle passed, water splashed, causing malfunctions in the sensors. We carried out sinking correction work using the Upcon method and restored the water gradient within a short construction period. 【Site Information】 Chiba Prefecture / Nagareyama IC Total construction area: 875 square meters Construction period: 8 nights

[Construction Case] Sugar Factory: Filling Work for the Void Under the Concrete Floor in the Turbine Room

We receive requests because it can be constructed in a short period of time! Using urethane for subsidence correction.

We would like to introduce a case of "filling the voids under the concrete floor in the turbine room" at a sugar factory in Hokkaido. During excavation work next to the external building of the turbine room for another project, a void with a depth of 380mm was discovered under the concrete floor. Since a turbine is installed above in the building, we implemented void filling work as a measure to prevent subsidence. We injected polyurethane resin under the concrete floor in the turbine room to fill the voids, and after the injection, we confirmed the filling using a CCD camera, ensuring that the polyurethane resin was densely filled, and completed the work. 【Case Summary】 ■ Construction Area: Approximately 70m2 ■ Maximum Void Depth: 380mm ■ Construction Period: 1 day ■ Area: Kamikawa District, Hokkaido *For more details, please refer to the PDF document or feel free to contact us.
