Environmentally-friendly mud-based propulsion method "Success Mall Method"

Improving environmental issues while leveraging the advantages of conventional construction methods! Capable of handling large boulders, rolling stones, and bedrock!

The "Success Small Method" is a construction technique that leverages the advantages of traditional mud slurry and earth pressure pushing methods (long distance, gravel compatibility, sharp curves, space-saving yards, etc.) while improving issues related to resource and work environments, and simultaneously pursuing a reduction in total costs. Traditionally, all the mud generated from excavation was disposed of off-site, but from an environmental perspective, we have developed a continuous soil classification device with a shower function (Master R) as a method to minimize the absolute amount discharged off-site. With various face plate adaptations, it can also handle large gravel, boulders, and bedrock. It has high torque, allowing for primary crushing with the face plate and secondary crushing with a cone crusher, enabling continuous soil discharge. 【Features】 ■ Long distance, gravel compatibility, sharp curves, space-saving yards ■ Improvement of resource and work environment issues ■ Continuous soil classification device with shower function to reduce off-site mud discharge ■ Total cost reduction *For more details, please feel free to contact us.

Subsurface Obstacle Adaptable Slurry Shield Tunneling Method *Performance Collection by Obstacle Type Available!

The milling mall method is safe even when obstacles appear! A thrust method chosen nationwide, compatible with diameters from φ800 to 3000 mm. *Registered with NETIS.

The underground obstacle response type mud-based thrusting method "Milling Mole Method," equipped with four special functions: exploration, improvement, cutting, and guidance, consists of three devices: a tunneling machine, a special telescopic pipe, and a special injection pipe, allowing for the fine cutting and discharge of underground obstacles. Using electromagnetic waves, it explores metal obstacles ahead while thrusting and can also improve the ground from within the tunneling machine before and after the detected obstacles. In the event that an obstacle is detected, the special telescopic device can be used to cut through the underground obstacle at ultra-low speed, allowing for continued thrusting. Furthermore, a system is also equipped to guide the tunneling machine to a designated position by installing a receiving coil at the specified location within the arrival shaft, enabling high-precision arrival even in the presence of obstacles. 【Performance by Obstacle Type】 ■CASE-6 Steel Sheet Pile 3W Cutting ■CASE-7 Steel Sheet Pile 3 & H Steel Cutting ■CASE-8 Wooden Pile & Steel Sheet Pile Cutting ■CASE-9 H Steel & Existing Manhole Wall Cutting ■CASE-10 Underground Continuous Wall & Metal Object Cutting *For more details, please refer to the PDF document or feel free to contact us.

Underground Obstacle-Responsive Slurry Shield Tunneling Method "Milling Mall Method"

It is possible to directly reach the existing shield through the application of metal cutting technology! We are currently presenting examples of construction where direct cutting was performed on existing shields.

The "Milling Mole Method" is equipped with a specialized bit designed for cutting through obstacles using a tunneling machine. It allows the cutter of the tunneling machine to make ultra-low-speed contact with obstacles through a special telescopic pipe, enabling cutting through the rotation of the cutter. This operates on the same principle as lathe machining. A significant feature of this construction using the "Milling Mole Method" is that it achieved direct cutting of steel segments without performing mirror cutting. Since improvements to the protective measures of the existing shield section could not be made from the surface, a boring machine was mounted, allowing for injection from within the tunneling machine (using a dual-pipe strainer method with multiple phases). Additionally, a formwork for cutting connection was installed inside the existing shield, and fluidized treatment soil was placed, allowing for direct cutting at ultra-low speeds and safely avoiding the risks of water inflow and subsidence accidents that occur during mirror cutting. Previously, mirror cutting was performed from within the shield, raising concerns from customers about the risks to the surrounding environment due to groundwater inflow and ground collapse associated with that construction. We proposed direct cutting of the existing shield, and after executing the construction, we successfully reached the target without affecting water inflow or the surrounding environment, resulting in great satisfaction from the client! 《You can download the construction case from the PDF below!》
