Two-way construction method

The basic system is a mud-based method. It is a construction method considering the installation type thrusting construction for existing underground structures.

This technology sends high-concentration mud water to the cutting edge and applies a mud water 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 excavation machine body will be pulled up after construction, and the "remaining type," which is designed to utilize the excavation machine body as a pipeline. It can accommodate sharp curve construction and long-distance pushing 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 ■ Supports low cover construction ■ Prevents collapse of the excavation profile, allowing for excavation within the ground *For more details, please refer to the PDF materials or feel free to contact us.
