Catalog & Case Studies / Construction of Small-Scale Thick-Walled Continuous Walls "Mini-Wall Method"

Packed with fundamental knowledge and case studies! We are currently offering a free catalog and case study collection on the mini-wall construction method, which can accommodate narrow sites and is capable of construction at a maximum depth of 20 meters with small machinery!

The "Mini Wall Method" is a construction technique that creates a soil-cement underground continuous wall with high water-stopping properties and uniform strength in the vertical direction by mixing and agitating cement slurry discharged from the base ground and the bottom end of the post using a chainsaw-type cutter mounted on a cutter post. Since uniform thickness walls can be created, it is possible to install core materials at arbitrary intervals, allowing for greater flexibility in soil retention design and the construction of economical soil-retaining water-stopping continuous walls. ■ We are currently offering a catalog summarizing basic knowledge and a collection of construction examples as a gift! 【Features of the Mini Wall Method】 ■ Due to the uniform thickness of the wall, the installation interval of the stress core material can be set arbitrarily. ■ Wall thickness can be adjusted by changing the cutter bits. ■ Construction close to structures and at property boundaries is possible. ■ The use of a suspended leader allows for step construction (5-6 m). * Please refer to the PDF data of the catalog and construction examples of the "Mini Wall Method" available for download.

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.*

MJS Method (Metrojet System)

Enables large-diameter high-pressure injection stirring in all directions from horizontal to diagonal and vertical!

**Principle** To address the shortcomings of the jet grouting method, we have developed a new construction device and a porous pipe. The most significant feature of this method lies in the mechanism for discharging the cut spoil. Traditionally, the jet grouting method relied solely on air lifting for spoil discharge. In contrast, the MJS method forcibly sucks the spoil into a dedicated pipe and transports it to the surface, allowing for construction at any angle from horizontal to diagonal. Additionally, by adjusting the amount of spoil discharged based on pressure management within the ground, this method enables the suppression of ground deformation such as uplift and settlement associated with injection mixing. **Features** - Capable of horizontal, diagonal, and vertical construction - Does not affect surrounding ground - Enables ground improvement at great depths - Consolidates spoil treatment - Prevents contamination due to improvement - Allows selection of improved body *For more details, please feel free to contact us.*

JSG method / CJG method

Core methods of ultra-high pressure jet grouting! Jet grout "JSG method" "CJG method"

The jet grouting method is a technique that uses ultra-high-pressure jet fluids to cut into the ground and improve the soil. There are two types of jet grouting methods: the "JSG method," which applies pressure to the curing material while excavating the soil and simultaneously mixes the soil with the curing material to create a cylindrical solidified body, and the "column jet method," which cuts the soil with ultra-high-pressure water, discharges the slurry to the surface while filling it with curing material, also creating a cylindrical solidified body. These methods can accommodate soil improvement under various geological conditions, depths, and other circumstances. 【Features】 ■ Reliable and certain construction is possible ■ A wide range of improvements that are not affected by the target soil type ■ High adhesion construction is possible ■ Large-diameter soil improvement can be achieved with small holes, allowing for closer construction to buried objects ■ Appropriate improvement strength can be set according to the improvement purpose ■ Economical and safe materials ■ Versatile mechanisms and compact equipment *For more details, please feel free to contact us.

Mode Cell Method

Acquisition of technical evaluation: A mechanism that is easy to repair without compromising the basic performance, enabling inexpensive and rapid repairs during liquefaction.

What are reliable ground improvement methods for liquefied ground? - The occurrence of earthquakes cannot be predicted. - The magnitude of earthquakes cannot be predicted. - The presence or absence of liquefaction cannot be predicted. - The extent of liquefaction cannot be predicted. - The amount of differential settlement due to liquefaction cannot be predicted. - The cost of repair work cannot be predicted. Therefore, based on the premise that some degree of differential settlement damage to single-family homes during an earthquake is unavoidable, we considered that by incorporating a mechanism during new construction that allows for leveling a tilted foundation using a mode cell anchor bolt with an adjustable length via a movable nut, it would be possible to carry out repairs without compromising the original strength of the foundation. The mode cell method, realized for the first time with the mode cell anchor bolt, is the solution.

This construction method allows for waterproofing simply by covering with FRP molded products (such as tile bar, slate roofs, and folded plate shapes) instead of applying waterproof coatings or sheets. Due to the lightweight nature of the FRP molded products, which weigh between 2.5 to 5 kg/m², the burden on the roof is minimized. This also makes installation on sloped roofs easier and enhances the safety of workers. It is possible to install FRP molded products up to 13 meters in length, which, combined with their lightweight nature, leads to a reduction in construction time. 【Features】 - Lightweight and reduced construction time - Energy-saving - Recyclable materials and methods - Increased longevity of buildings, enhanced roof strength, and improved corrosion resistance of roofs - Insulation method *For more details, please download the PDF or contact us.

Self-supporting retaining wall "YOSAKU Method"

Reduce excavation volume and earthworks to shorten construction time and cut costs!

The "YOSAKU Method" is a construction technique characterized by an integrated structure of concrete walls and pile foundations to support lateral earth pressure and vertical loads. It allows for low costs and minimizes the amount of soil excavation, resulting in a highly efficient retaining wall. It is particularly effective in sloped areas or places with elevation differences. Unlike conventional methods, it does not require a foundation base, making it possible to reduce soil-related issues during excavation (such as movement, processing, and softening) as well as their impact on the surrounding area and costs. 【Features】 ■ Reduces the amount of excavated soil and earthwork, significantly decreasing the workload ■ Shortens construction time and reduces costs ■ No foundation base required ■ Reduces soil-related issues during excavation (such as movement, processing, and softening) and their impact on surrounding costs *For more details, please refer to the PDF document or feel free to contact us.
