![Underground Obstacle-Compatible Slurry Shield Tunneling Method [Milling Mole Method]](https://image.www.ipros.com/public/default/object/noimage_l.gif?w=280&h=280)
Eliminate the problems of underground obstacles. The milling mole method allows for the exploration, cutting, improvement, and guidance of obstacles while advancing.
One of the concerns in construction work is underground.
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.
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!》
A construction method for installation pipes using a combined auger and pressure insertion technique that incorporates special branches with earthquake resistance and water tightness!
The "Strike Method" is a pipe installation and advancement technique that utilizes a combined auger and pressure insertion method to achieve effective ground improvement by injecting chemical solutions after the arrival of the casing pipe at the main pipe to be installed. Even when installing the main pipe under heavily trafficked roads, construction can be carried out from a distant shaft, contributing to the alleviation of traffic congestion. 【Features】 ■ Installation of a φ150mm pipe onto a φ200mm PVC pipe ■ Installation onto fume pipes and shields ■ φ2,000 casing shaft initiation (φ1,500 casing shaft initiation is also possible; separate calculations apply) ■ Chemical solution injection to the reach section can be performed from within a φ1,500 casing pile ■ Adoption of special branch pipes that are earthquake-resistant and watertight *For more details, please download the PDF or feel free to contact us.
Response to stagnant water sand layers! A small-diameter pipe jacking method that can control the amount of soil and sand intake during advancement.
The "Three-Pipe King (R) DRM MVP301" is a small-diameter pipe jacking method suitable for saturated sand layers. It allows for control of the amount of soil intake during jacking. Complete water stoppage can be achieved when setting the pipes, preventing auger sticking. 【Features】 ■ Permeability coefficient K = 10(-2cm)/SEC to 10(-3cm)/SEC or less ■ Water head difference within 3 to 5m ■ Control of soil intake during jacking is possible ■ Tools can be used interchangeably with other models ■ Launching from a shaft with a diameter of φ1500 is possible (Note: Pipe length 0.5m) *For more details, please download the PDF or feel free to contact us.
Achieving renovation promotion with excellent cost-effectiveness and construction speed! Construction is possible even under conditions with groundwater.
The "Berliplace method" involves inserting a pilot crusher into an existing pipe, expanding and crushing the existing pipe while advancing with a tunneling machine that collects debris, and pushing in a new pipe (PVC pipe). The pilot crusher is equipped with crushing blades and a water-stopping device, allowing construction even under groundwater conditions. It contributes to the longevity of PVC pipes and reduces lifecycle costs. 【Features】 ■ Contributes to the lifecycle cost (LCC) and longevity of sewer pipes through the advantages of PVC pipes ■ Proven advancement rate of over 15m per day ■ Cost reduction achieved through increased tunneling speed ■ Capable of reaching the first manhole ■ Economical *For more details, please refer to the PDF document or feel free to contact us.
Easily construct pipelines in densely populated urban areas! A construction method that shortens the construction period.
The "Dual Shield Method" is a shield switching type of thrust construction method that incorporates the advantages of both thrust and shield methods. It employs a cost-effective thrust method for gentle curves and straight sections, while using the shield method for sharp curves and continuous curve sections. This makes it easier to construct pipelines in densely populated urban areas, significantly reducing costs. 【Features】 ■ Capable of sharp curves (R10m) without the need for rotating shafts at intersections ■ Can be constructed with shafts sized for thrust methods ■ Equipment from thrust methods can be used ■ Average daily progress increases by combining thrust methods ■ Using a mud slurry method increases thrust extension *For more details, please download the PDF or feel free to contact us.
Adapted for depths of over 50m underground! A thrust construction method that penetrates the ground without excavating the surface.
We would like to introduce our "Shield Method" for constructing tunnels underground. Using a tunnel boring machine called a "shield," we advance underground while preventing soil collapse, safely conducting excavation and lining work inside to build the tunnel. This method adapts to a wide range of soil types and minimizes subsidence. It is also suitable for depths of over 50 meters underground. 【Features】 ■ Adaptability to a wide range of soil types ■ Minimization of subsidence ■ Simultaneous backfill injection is possible ■ Suitable for deep depths and high water pressure *For more details, please refer to the PDF materials or feel free to contact us.
Achieving low thrust! Adopting a unique method for the excavation soil transport mechanism and the mud transport method.
We would like to introduce our "Mud Density Method" for thrusting, which can accommodate various soil types through head replacement. In this method, high-density mud water is pumped to the tip of the thrusting machine, stabilizing the face while rotating the cutter to advance, and soil is removed using a vacuum pump. The standard thrusting distance is approximately 100m to 300m per span, but thrusting over 500m is also possible. Additionally, curved construction can be performed. 【Features】 ■ Adoption of overcut ■ Stability of tail void ■ Achievement of low thrusting force ■ Realization of sharp curve thrusting ■ Smooth removal of cobbles ■ Fresh air is always supplied inside the pipe *For more details, please refer to the PDF document or feel free to contact us.
