An application of an innovative rock-fracturing excavation method to in-service tunnels

Fujita Corporation has applied an innovative rock-fracturing method to create an escape tunnel connecting two major Japanese road tunnels (the Hinosan-tunnel on the Hokuriku Highway and the Kanechika-tunnel on the Chugoku Highway). The innovative FON drilling method uses conventional machines to drill continuous holes in the tunnel face and removes rock using fracturing machines.  The connecting tunnel built in the project had a tunnel with a cross-section of 10 - 20 m2, and due to use of the FON drilling method we were able to excavate the tunnel in extremely hard rock without blasting methods near in-service tunnels for the first time in Japan.

An application of Fujita’s “Robo-Q” robot to construction sites

Fujita’s remotely-controlled “Robo-Q” robot system was originally developed for use in disaster recovery operations, but is now being successfully applied to more everyday tasks, such as chipping concrete surfaces of a tunnel.  As a result, the operator is not exposed to working environments that are very poor due to noise and dust.  Based on this success Fujita will apply the robot system to common construction sites in order to improve other kinds of poor working environments and safety matters for operators in addition to disaster restoration applications.

Fujita Corporation uses HMP (High Capacity Micro-pile) method for seismic strengthening of a water station

High Capacity Micro-pile (HMP) method is an innovative foundation technology developed in the USA. Fujita Corporation is currently using HMP for to seismically strengthen the foundations of a water station located at Kameido in central Tokyo.   HMP is particularly suitable for such projects as it can be undertaken in confined spaces, and has bearing capacity for both compression and pullout with relatively small diameter piles. In this project, batter HMPs are being installed between existing piles at depths of more than 35m (The original piles were installed 35 years ago with φ600mm at 2m spacing).

Issuing an annual environmental report “Fujita Eco Report 2004”

Fujita Corporation acknowledges that the construction industry is strongly connected with environmental issues, and puts emphasis on three primary policies: “reduction of environmental burdens in construction activities”, “contribution to comfortable environment through construction activities” and “establishment of an operational base with a strong commitment to environmental issues”. To show specific activities in detail, an annual report “Fujita Eco Report 2004” has been issued (http://www.fujita.co.jp/kankyo/Ekor-hp/E-report.htm).

Business development of Fujita Corporation’s low-cost factory construction method

Fujita Corporation has been engaged in the development of a low-cost factory construction method called “FLF (Fujita’s Low-cost Factory)”. Recently the method has been improved and it is now possible to construct factories in just two and a half months at a construction price of US$1100 per 3,3m2 (for factories with a maximum span of 42m). The improved method can be applied to low-cost facilities construction s for various types of factories, shipping storages, shopping centers, gymnasiums and so on.

Introduction of in-situ soil flushing method from USA to clean up contaminated soil and water

Fujita Corporation has introduced an “in-situ surfactant flushing method” from the USA to assist those of our clients who need to clean up soil and water contaminated by petroleum products. The characteristics of this technology are 1) the facility for flushing is very compact, 2) remediation works are possible while facilities like oil tanks are active. In the future, pilot scale projects will be undertaken in order to verify the effectiveness of this technology for Japanese soil, and an efficient remediation system with low-cost and short construction period will be established.

Consecutive construction contracts from “ProLogis Corporation” for large- scale logistics facility

Fujita Corporation has already won three contracts from the Japanese affiliate of the US-based ProLogis Corporation for the construction of logistics facilities in Japan. These contracts were won on the basis of Fujita Corporation’s expertise and experience in working with foreign companies. Recently, Fujita Corporation has won two more ProLogis contracts, and one of them, “ProLogis park Yokohama” is the biggest logistics facility in the metropolitan area (with a total floor area of 119,660 m2 ). At the facility, a base-isolated structure will be used to maximize worker safety, protect client stock, and maintain asset value.

In future, Fujita Corporation will continuously support clients with suitable technologies and expertise from planning to construction stage to meet clients’ requirements.
