Notice of the 44th "Latest Construction Method and Technology Training Seminar"

I would like to report on a new initiative that utilizes the cutting function of steel obstacles.

Yasuda Engineering Co., Ltd. will conduct a seminar at the 44th "Latest Construction Technology Seminar on Advanced Propulsion Methods" held in Tokyo and Osaka. We will report on our new initiatives utilizing the steel obstacle cutting function of the milling mole method. This seminar is accredited as a "Continuing Professional Development (CPD) Program" by the Japan Society of Civil Engineers. (CPD credits: 6.5) We sincerely look forward to your attendance. [Overview] ■ Seminar Time: 14:55 - 15:50 ■ Seminar Content: Challenging New Areas with the Milling Mole Method - New Initiatives Utilizing the Steel Obstacle Cutting Function - *For application details, please refer to [Details on How to Apply for Participation Here]. *For more information, please refer to the PDF document or feel free to contact us.

• Special Construction 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!》

Introducing a case study of shield arrival construction using the milling mall method!

The "Milling Mole Method," equipped with four special functions: exploration, improvement, cutting, and guidance, is a ground obstacle response type mud-based thrusting method. It 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. In the construction of the inflow pipe sewer system for the second Nakagawa Chubu rainwater adjustment pond, the Milling Mole Method was used to carry out the shield arrival work. Milling cutting length: The assembly precision of the steel formwork at the arrival section inside the existing shield, L=1.520m from the outer circumference of the existing shield, was excellent, and there were no leaks of groundwater or muddy water during the placement of fluidized treated soil or during the shield cutting with the tunneling machine, allowing for safe cutting. 【Construction Example】 ■Location: Nagoya City, Aichi Prefecture ■Client: Nagoya City Waterworks Bureau ■Contractor: Asanuma Corporation ■Nominal Diameter: φ2200mm ■Thrusting Length: 101.520m ■Underground Obstacles: Direct access to the existing shield Inner diameter of the existing shield φ3750mm *For more details, please refer to the PDF document or feel free to contact us.

We are pleased to announce that Gywood has been recommended as a featured building material in the special project "Recommended Building Materials" at the Housing Business Fair within the comprehensive exhibition for housing, architecture, and real estate [BREX Kansai]. We will be exhibiting in the "Recommended Building Materials and Equipment" zone, where professionals from the field gather to showcase their recommended materials. We invite everyone to stop by and visit us.

Seminar Overview As the labor shortage in manufacturing sites becomes more severe, the labor costs and time losses associated with the "transportation" of products and components, as well as "cleaning" within factories, have become critical management issues that cannot be overlooked. In this webinar, we will introduce the latest use cases of "Autonomous Mobile Robots (AMR)" and "Commercial Cleaning Robots" that achieve productivity improvements in manufacturing environments. We will specifically address questions such as "How are other companies operating these technologies?" and "What kind of cost reduction effects can be expected after implementation?" by providing concrete explanations of actual before-and-after scenarios and operational flows. Factory managers and members of production technology and DX promotion departments who want to advance automation and efficiency on-site are encouraged to participate! Recommended for: - Those who are unsure about where to start with automation, labor reduction, and DX in their factories. - Those who want to alleviate labor shortages on-site and focus resources on core operations to improve productivity. - Those who want to stay updated on the latest trends in the use of transportation robots (AMR) and cleaning robots.

Our representative, Koichi Yokoyama, will be speaking at an online seminar scheduled for November 27 (Friday). Participation is possible from anywhere in the country.
