Solving issues with construction methods! "Case Studies for Problem Solving Available"

The advancement construction method often faces many challenges during the excavation process. Here are examples of how those problems were solved!

Have you ever faced any of these issues when performing construction using thrusting methods? ▶ Construction was halted due to encountering obstacles like wooden stakes or H-beams... ▶ The time and cost of construction increased, leading to delays or interruptions... ▶ Construction over difficult distances could not be managed with standard equipment and methods... The "Milling Mole Method" solves these problems associated with thrusting methods! 【Example of a resolved case】 ✔ Sewer construction in Osaka City Planned to push 127 meters in one span using a standard mud slurry method with a diameter of φ80mm. Immediately after starting, the machine encountered wooden stakes, making it impossible to proceed, and the excavation was halted. By changing the plan to adopt the Milling Mole Method, the presence of obstacles was confirmed by discharging wood chips, and the thrusting was completed. ✔ Sewer construction in Osaka Prefecture Planned to push 119 meters in one span using a standard mud slurry method with a diameter of φ1800mm. While excavating about 10 meters, the machine encountered support piles of a bridge pier, making it impossible to proceed, and both the excavation machine and thrusting pipe were left underground. By changing the plan to adopt the Milling Mole Method, re-excavation was carried out from the same launch shaft. The reinforced concrete pipe that became an obstacle was cut, and the discharge of metal fragments, thrusting pipe collars, and rebar was confirmed, allowing safe passage through the obstacle section, and the thrusting was completed. *We are currently providing materials such as "Case Studies of Problem Solving" and "Comparison of Methods for Dealing with Obstacles in Thrusting Methods" from the PDF!
