Milling Mall Method: Gas Construction Case Studies

Milling Mall Method: Gas Construction Case Studies

We have published a case study of gas construction using the milling mall method implemented by our company!

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 precise cutting and removal of underground obstacles. This document includes case studies of gas construction using the Milling Mole Method. It features photos of underground obstacles cut on-site, along with comments from the site personnel. [Featured Cases] ■ New tunnel construction for the 2-1 Otemachi District plan in Chiyoda Ward, Tokyo ■ Installation of the Ise Bay crossing gas pipeline in Yokkaichi City, Mie Prefecture (gas conduit construction) ■ Main construction for the MAKP750A in North Shinagawa, Shinagawa Ward, Tokyo (Sankyo Bridge Phase III construction) *For more details, please refer to the PDF document or feel free to contact us.

Small caliber pipe propulsion device "Iron Mall TP40SC-2L"

Small caliber pipe propulsion device "Iron Mall TP40SC-2L"

For pushing PVC pipes with a diameter of Φ200 to 300mm! A simple small-diameter pipe jacking machine that accommodates a wide range of soil types.

The "Iron Mall TP40SCL-2" is a small-diameter pipe jacking machine that can push a 1-meter pipe from a φ1.8m liner plate, allowing for efficient pushing even in narrow job sites. The pushing device has a slim design, and the control unit can be placed on top of the pushing device, making work inside the shaft easy. Additionally, the screw excavation method requires minimal surface equipment, and the hydraulic unit operates on an engine-driven method that does not require a generator, resulting in a small footprint on the surface, enabling work in tight spaces. 【Features】 ■ Can push in sites with limited space ■ Easy to transport and retrieve ■ Compatible with a wide range of soil types, from ordinary soil to hard soil and saturated gravel layers ■ Achieves faster pushing *For more details, please download the PDF or feel free to contact us.

Pneumatic propulsion device "Grundrum"

Pneumatic propulsion device "Grundrum"

Construction is possible even in narrow spaces! There is no need for support walls, and it can be easily combined with open-cut methods.

The "Grun Drum" is a pneumatic propulsion device that uses compressed air from a standard compressor. Using the power of compressed air, the piston inside the product strikes the main head, and this impact force is transmitted to the steel pipe through the ram cone, enabling the propulsion of the steel pipe. Due to its simple structure, it is an extremely easy product to operate and maintain. 【Features】 ■ Each part of the machine is made from carefully selected materials ■ Each component is precisely processed, ensuring trouble-free operation ■ The seals are complete, resulting in minimal consumption of compressed air and oil ■ Simple structure ■ Extremely easy to operate and maintain *For more details, please refer to the PDF document or feel free to contact us.

Propulsion from any direction! Pneumatic propulsion device "Grundrum"

Propulsion from any direction! Pneumatic propulsion device "Grundrum"

This is an introduction to the efficient, lightweight, and compact "Grundram" method.

The Grundram is a pneumatic propulsion device that uses compressed air from a standard compressor. Using the power of compressed air, the internal piston of the Grundram strikes the main head, transmitting the impact force through the ram cone to steel pipes and other materials, making it suitable for various applications. 【Construction Method & Overview】 ■ Grundram Installation Pipe Propulsion Method - A method that joins the installation pipe to the existing pipe after drilling the existing pipe. - Highly adaptable to soil conditions. - Capable of propulsion in gravel and cobblestone mixed soil. - Chemical injection can be performed to the limit. - No need for support walls or reaction anchors. - The propeller is lightweight and compact. - Requires a small working space. ■ Grundram Steel Pipe Piling Method - A method that drives steel pipe piles into the ground using the impact force of the Grundram. - Allows for steel pipe work in low and narrow spaces, such as basements. - Equipment is extremely lightweight and compact. - Can be used in gravel and cobblestone mixed soil, with a wide range of applicable soil types. *For more details, please refer to the PDF or feel free to contact us.
