LL-Fp method

LL-Fp method

Shortened construction time and reduced costs with Drill Jumbo construction. No need for specialized drilling machines or personnel.

The technology allows for the installation of φ139.8mm large-diameter steel pipes over long distances using a drill jumbo, which is a general-purpose excavation machine for mountain tunnels, without the need for specialized machinery. Traditionally, it was considered difficult to install such large-diameter steel pipes into the ground using a drill jumbo, but various innovations and the development of specialized tools have made this possible. 【Features】 ■ Improved workability ■ Enhanced settlement suppression effect ■ High construction precision ■ Reduction in process and costs ■ The bending rigidity of the steel pipe is about three times that of AGF (in the case of double-pipe specifications) *For more details, please refer to the PDF document or feel free to contact us.

Water Stopping Method "HSB Method"

Water Stopping Method "HSB Method"

This is an introduction to construction methods that ensure water tightness while considering ground deformation due to seismic activity!

The "HSB method" is a construction technique that ensures watertightness by filling the joints of concrete components with a specialized sealing material known as "high-elastic adhesive sealing material" from the inside, taking into account ground deformation due to seismic activity and other factors. The method is applicable to typical examples such as precast concrete box culverts and large reinforced concrete flumes. Additionally, it can be applied to concrete structures where the displacement of the joints required by design falls within the deformation range specified by this method. 【Features】 ■ High-elastic adhesive sealing material ■ Watertightness against joint shapes and joint displacement ■ Joints that can withstand Level 1 and Level 2 seismic motions in sewer pipelines *For more details, please refer to the PDF materials or feel free to contact us.

Super Preservation Method for Long-lasting Bed Plates

Super Preservation Method for Long-lasting Bed Plates

Construction can be carried out without damaging while the vehicle is in operation! Introducing methods for extending the lifespan of bridge deck slabs.

The "Super Hozen Method" is a construction technique aimed at extending the lifespan of bridge deck slabs. The construction involves securely fastening mesh rebar to the underside of the existing deck slab using tapered T-type anchors. It alleviates vibrations and impacts on the deck slab, and after applying a thick layer of polymer cement mortar (Hozen material #10), low-pressure epoxy resin injection is performed to completely integrate with the existing deck slab. This method allows for construction without damaging the structure while vehicles are in operation, ensuring a reliable rejuvenation through three stages of lifespan extension measures. 【Features】 - No restrictions on vehicle passage - Construction possible without damage while vehicles are in operation - Reliable rejuvenation through three stages of lifespan extension measures *For more details, please refer to the PDF document or feel free to contact us.
