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.

Daito Shiko Co., Ltd. will exhibit at "Bunshi MESSE 2026" held at My Dome Osaka from Tuesday, August 4, 2026. On the 3rd floor of the exhibition venue, we plan to showcase popular products from Daito Shiko, including stationery and crafts. There will also be sales of original goods in the shopping zone on the 1st floor. If you are looking for SP tools, promotional items, or novelties, please be sure to visit our booth.

We will be exhibiting at the "Sewage Exhibition '26 Tokyo" held at Tokyo Big Sight and Nikkei Online Exhibition Hall. This exhibition is held annually with the aim of showcasing and introducing new technologies and equipment in a wide range of fields related to sewage, based on the results of technological development by sewage-related companies nationwide, targeting local governments and other entities that manage sewage projects. It also aims to foster understanding and interest in sewage among the general public. We sincerely look forward to your visit. 【Exhibition Content】 1) Concrete Product Transport and Installation Method "Lift Roller Method" (Construction demonstration, panel display, video screening) 2) Flood Prevention Precast Wall "MC Waterproof Wall Method" (Panel display, video screening) 3) Seismic-resistant Box Culvert with Rubber Ring "DCJ Box Culvert" (Construction demonstration, panel display) 4) Introduction of Efforts Toward Decarbonization

~ A high-efficiency customer attraction strategy where homebuyers come in saying "I saw it on ○○!" and a product/design strategy that is specifically requested as "I want to build with Harbor!" ~ In an era where simply creating a "good house" is not enough to survive, rising material costs, labor shortages, and intensifying competition with major companies have made the environment surrounding local construction companies more challenging than ever. Amidst this, Harbor House, which has been established for 19 years in the fiercely competitive Niigata Prefecture, has achieved an annual completion of 450 houses and is now the number one in the number of starts in Niigata Prefecture. Its strength lies not in a single charismatic leader, but in a thoroughly refined "system." Customers who say, "I came after seeing your website" are reliably guided to contracts through a high-efficiency sales flow based on "batting average management." In this online seminar, we will generously share the know-how of customer attraction, product, and management that Harbor House practices with business owners. We will present the shortest route to becoming a "construction company that continues to be chosen" in your business area. ◇ Detailed information and application https://x.gd/pUe2b ◇ Phone inquiries TEL: 025-383-8881
