Civil engineering/construction work
Temporary bridge construction
Construction and dismantling of temporary bridges used as detours when replacing aged bridges, as well as working platforms and temporary bridges for construction on civil engineering and building construction sites.
Hi-BRIDGE construction method®
In this method, the Hirose G-piled jetty® is used as a superstructure, and a steel pipe pile is used as a substructure. This method can reduce a significant number of piles and achieve a reduction in the construction period by erecting superstructure substructure braces as a unit, and it also supports vertical erection.
Hi-RoRo construction method®
A piled jetty with a reduced construction period can be erected by using the Hirose G-piled jetty® as a superstructure and a pipe support as a substructure.
Construction and dismantling works of temporary bridges
Temporary bridges are constructed by using our proprietary temporary bridge materials, such as Pre-girder® bridges, which are assembled plate girder bridges, and KD bridges, which are truss bridges, when replacing aged bridges and pedestrian bridges or in the event of a disaster or other emergency.

- Kanmuriyama Pass Road No.5 Bridge lower part construction work
On National Highway 417 on the border between Gifu Prefecture and Fukui Prefecture, Kanmuriyama Pass Road has been developed to eliminate sections where car traffic is impossible, to shorten the travel time, to ensure road passability in the event of a disaster, and to achieve the creation of a wide-area tourist and sightseeing zone. Our piled jetty for construction, which can be constructed within the scheduled construction period, was adopted as the construction road required for this bridge/tunnel development project.
The piled jetty, with a reduced construction period, uses the G-piled jetty®, a NETIS registered product, as a superstructure and a steel pipe pile as a substructure. By using the KANBE quickly joint®, error absorbing connectors, at the steel pipe joint sections and the Hirose Mega-clamps® for braces, a reduction in the construction period was achieved by erecting the substructure as a unit.

- Aigawa Dam Construction Project
Aigawa Dam (flood control dam) has been constructed on the Aigawa River of the Yodo River System in the northern part of Ibaraki City, Osaka Prefecture, to maintain normal functioning of the stream, to make appropriate adjustments during floods, and to improve the environment of the downstream river. Our piled jetty, with a reduced construction period, using Pre-girder® III and Hi-RoRo construction method®, was adopted as a piled jetty for construction. The piled jetty using the G-piled jetty® as a superstructure and a pipe support as a substructure is useful as a piled jetty for construction, as well as to reduce the construction period.

- Takachiho Hinokage Line Otome Ohashi Temporary Piled Jetty Construction Project
On the Takachiho Hinokage Line, which is a forest trunk road currently being developed as the longest forest road in Miyazaki Prefecture, the Otome Ohashi is to be erected over the Karisoko River flowing on the border between Takachiho Town and Hinokage Town, for which our piled jetty, with a reduced construction period using the Hi-RoRo construction method® is used as a superstructure. The piled jetty uses the G-piled jetty® as a superstructure and a pipe support as a substructure.
