Milling Mall Method Construction Case: Supply Work for the Nishishinbashi 1-Chome Project
All-rounder for construction work! Cutting 8 pieces of obstacle H300 at 4 locations!
This is an introduction to the achievements of the new construction work for the Hibiya Route tunnel as part of the Nishishinbashi 1-chome project supply work. After starting, we cut the first obstacle H300 at about 10 meters, and then continued to cut the second and third H300 obstacles at intervals of about 2 meters. We planned to cut the remaining three H300 obstacles before reaching the destination. However, in reality, we only cut up to the third obstacle from the beginning, and we did not encounter the remaining three obstacles (H300). 【Construction Case】 ■ Project Name: New construction work for the Hibiya Route tunnel as part of the Nishishinbashi 1-chome project supply work (Part 1) ■ Client: Marunouchi Thermal Supply Co., Ltd. ■ Contractor: Takeuchi Civil Engineering Co., Ltd. ■ Pipe Diameter: 2000 ■ Pushed Length: 78.30 m ■ Soil Type: Sandy Silt ■ N Value/Gravel Rate/Maximum Gravel Diameter: N=2 G=0% φmax=0mm ■ Construction Period: 2011.12.11 to 2012.2.8 (2 months) ■ Type of Obstacles: H-300, 4 locations, 8 pieces * For more details, please refer to the PDF document or feel free to contact us.
