WHAT'S NEW

Bridgestone Museum of Art Renovation Report: No. 3

2016.10.17
Construction of the new Bridgestone Museum of Art began in June of 2016.
The work is now in the retaining wall construction phase, which means, in excavating the site and foundations, reinforcing the sides of the excavated area to prevent the material around the site from collapsing into the excavation site and to prevent outflows of earth and rock. An SMW (soil-mixing-wall) pile driver is used to mix cement, soil, water, and other components while drilling 35-meter-deep boreholes. Then H-beams (H-shaped steel beams) of a maximum length of 28.5 meters are inserted in the boreholes, to build the retaining wall. The process appears to be dynamic and forceful, but is based on very rigorous calculations. In total, 371 steel beams will be precisely inserted into the ground! The retaining wall work began in September and will continue until mid November.

These triple augers play a major role in drilling the boreholes. “Cement milk,” a slurry made of cement and water, is squirted out of their tips.

Steel beams 14.5 and 13.5 meters in length are connected to create 28 meter long beams. They are joined with millimeter-scale precision and weigh 5.5 tons!

The resulting steel beam is hoist by a crane and moved towards the borehole.
