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

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"

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!》

[NETIS Registered] No worries even if obstacles arise! A construction method that is starting to be chosen nationwide! Compatible with diameters from φ800 to 3000 mm.

The "Milling Mole Method," a ground obstacle response type mud-based propulsion 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.

*Exhibition of Sewers '18 Kitakyushu*

*Exhibition of Sewers '18 Kitakyushu*

We have showcased the "Underground Obstacle Response Type Mud Density Propulsion Method" that no longer fears obstacles!

**Exhibition Overview** Exhibition Name: Sewer Exhibition '18 Kitakyushu Date: July 24 (Tuesday) - 27 (Friday), 2018, for 4 days Time: 10:00 AM - 5:00 PM Location: West Japan General Exhibition Center Booth: C-822 **Exhibited Products** ■ Subsurface Obstacle-Compatible Slurry Shield Method The milling mole method is used in urban development and is a slurry shield method that safely performs construction by cutting through obstacles left underground. It can detect obstacles ahead of the excavation and discharge them as cutting powder of about 1 cm in size. If necessary, it allows for the injection of chemicals from within the machine and guidance of the tunneling machine using GPS. ■ Jet Method The jet method uses a CCD camera sensor to instantly measure the position of the tunneling machine on sharp curves. It enables long-distance and sharp curve construction in small-diameter tunneling. By using a dedicated pump cylinder and lubricant injection pipe for the jet method, it reduces the load on the pipe, allowing for long-distance tunneling even with small diameters. It is the most excellent all-around tunneling method that does not limit construction locations due to in-pipe measurement.
