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.*

basic information
The "MJS Method" is a construction technique that utilizes the kinetic energy of ultra-high-pressure jet fluids to perform ground cutting, hardening material mixing, and stirring to create solidified bodies. In this respect, it fully leverages the advantages of conventional high-pressure injection methods. Furthermore, this method aims to ensure that injection, cutting, mixing, and stirring are reliably performed under the same conditions at all times, by constantly monitoring and optimizing the injection conditions in the surrounding area. For instance, if it is necessary to control the pressure within the ground, the required measures can be activated, and adjustments can be made if there is a need to regulate strength or curing time. Additionally, in construction management, not only the pressure of the mud water within the ground but also the injection volume of the hardening material, injection pressure, air volume, air pressure, and other necessary data can be continuously monitored by management equipment, while also being stored as documentation for future reference. *For more details, please feel free to contact us.*

Company information
Our company was founded in 1958 and specializes in underground special civil engineering works such as underground continuous walls, underground obstacle removal, ground improvement, and pipeline construction. In recent years, we have expanded our business operations to include slope work and construction. There is a growing social demand for securing the natural environment, seismic reinforcement, liquefaction prevention, restoration of structures, and urban redevelopment, which have become pressing issues in recent years. In response to these social needs, we have developed seismic reinforcement and liquefaction countermeasure methods such as the "Ultra Multi-Point DP Method" and the "High Grip Grout Method." For structural restoration, we utilize our in-house developed restoration method called "Suiheikun," and for urban redevelopment, we are conducting research and development of new methods such as the "Hiro Work Kmigty Method," "Bauer Method," and "Super Top Method," aimed at underground obstacle removal. Additionally, as part of our eco-friendly initiatives, we are researching and developing methods that use bubble drilling fluid to reduce industrial waste, striving to contribute to society through high-quality construction and services. We aim to continue responding to the needs of the times by deploying a variety of specialized techniques and uniquely developed methods.
