The basic system is a mud-based method. It is a construction method that considers the installation type thrust construction for existing underground structures.

This technology sends high-concentration slurry to the cutting edge and applies a slurry pressure of 2 meters above the groundwater level, preventing the collapse of the excavation profile and allowing for excavation within the ground. There are two construction methods available: the "retrievable type," which assumes the main excavation machine will be pulled up after the thrust construction, and the "remaining type," which is designed to utilize the main excavation machine as a pipeline. It can accommodate sharp curve construction and long-distance thrusting without the need for auxiliary methods or equipment. 【Features】 ■ The basic system is mud concentration type ■ Both "retrievable type" and "remaining type" can be chosen ■ Accommodates curves and long distances ■ Suitable for low cover construction ■ Prevents collapse of the excavation profile and allows for excavation within the ground *For more details, please refer to the PDF document or feel free to contact us.
