NSPC W method

NSPC W method

NETIS registration! A lightweight embankment construction method that allows for shortening construction time and reducing costs by making panel materials self-supporting!

In developing a construction method utilizing lightweight embankment techniques, one of the issues identified is that the air-entrained lightweight embankment materials (air mortar, air milk) generate significant soil pressure due to fluidity and expansion pressure during curing. In conventional formwork methods, some form of reinforcement is typically implemented to resist and maintain these pressures. However, when using H-beams as reinforcement on the back of precast panels, the need for large machinery becomes a hindrance during the placement of lightweight mortar, compromising both workability and cost-effectiveness. Therefore, by applying tension to the NSC panels using rods and supporting the lower edge of the panels in a cantilever beam configuration, it has become possible to construct vertical walls, sloped walls, and curved walls. This achievement has led to significant reductions in construction time and costs, resulting in the completion of a technology capable of building exceptionally robust structures that have not been possible before. *For more details, please contact us or download the PDF.*

Shallow and Deep 4-Axis Method

Shallow and Deep 4-Axis Method

A shallow to medium-depth ground improvement method that can enhance a wide area using small machinery. *Transportation costs are minimized with small machinery! [NETIS: KT-170044-A]

The "Shallow-Deep 4-Axis Method" is a mechanical mixing ground improvement method that discharges cement slurry from a dedicated rod tip and mixes it during excavation. A technical management system for large cross-section construction (φ700mm×4 axes = 1.46m²) has been established using compact construction machinery. With an automatic posture control system mounted on a backhoe, a maximum improvement depth of 6m is possible, while a leader method allows for construction up to 15m deep. This method provides flexible ground improvement solutions, even in narrow construction sites, as well as large-scale ground improvement projects. 【Features】 ■ The Shallow-Deep 4-Axis processing machine can be mounted on general-purpose backhoes or self-propelled small cranes. ■ By following the operation manual for settings, stable ground improvement work can be achieved. ■ Two types of construction machines are available: one using an automatic posture control backhoe and another using a telescopic crawler crane in a guide leader method. ■ Patent No. 4920116 ■ NETIS Registration No.: KT-170044-A For more details, please refer to the catalog or feel free to contact us.

Dawn Construction Method

Dawn Construction Method

The birth of a savior for narrow site construction! A steel pipe pile method born from a thorough examination of the roles of blades and shafts.

The "Akatsuki Method" involves attaching a spiral wing steel plate to the upper part of a tip steel pipe, joining an axial steel pipe as a reinforcement material, and using a pile driver equipped with a rotary penetration device to rotate and penetrate it into the ground, utilizing it as ground reinforcement material. The tip of the reinforcement material, which receives significant ground reaction force, can be expanded as a wing section, and a main axial steel pipe with a smaller diameter than the tip steel pipe can be selected. Construction is possible not only with leader machines and pile driving vehicles but also, depending on the conditions, with an excavator. 【Application Range】 ■ Maximum construction depth: 10m (if soft layers continue and SWS is possible, up to 130D) ■ Applicable ground (tip ground): sandy soil (including gravelly soil), clayey soil ■ Applicable structures: - Buildings (3 stories or less, up to 13m in height, and a total floor area of 1500m2 or less) - Structures (retaining walls up to 3.5m in height, septic tanks, etc.) *For more details, please refer to the PDF materials or feel free to contact us.

Ground Improvement

Ground Improvement

Column improvement and surface improvement! The targets are weak clayey or sandy ground, etc.

"Ground improvement" involves artificially enhancing the properties of the ground or soil. The targets for improvement include weak clayey or sandy ground, unstable rock formations, and permeable rock formations. In "columnar improvement," cement-based solidifying materials are injected to a stable ground level, creating columnar bodies within the soil. In "surface improvement," cement-based solidifying materials are spread over relatively shallow weak ground, and the strength of the ground is increased through mixing, stirring, and compaction. 【Details】 ■ Columnar Improvement ■ Surface Improvement *For more information, please refer to the PDF document or feel free to contact us.
