The tunneling machine is equipped with a chemical injection mechanism at the front end! It is capable of water-stopping injection in the excess excavation area of the tunneling machine.
The "Uncle Mall Shuttle Method" is a construction technique that allows for the retrieval of the tunneling machine when encountering obstacles during excavation, followed by the removal of the obstacles and the re-insertion of the tunneling machine. Since the tunneling machine can be retrieved, there is no need for a reach shaft, and underground connections are possible. It is compatible with a wide range of soil types, including cohesive soil, sandy soil, gravel, gravel mixed with cobbles, and soft rock. 【Features】 ■ Retrieval and re-insertion of the tunneling machine is possible ■ No need for a reach shaft; underground connections are possible ■ Capable of handling obstacles ■ Compatible with a wide range of soil types, including cohesive soil, sandy soil, gravel, gravel mixed with cobbles, and soft rock ■ Equipped with a diameter expansion and contraction function for the tunneling machine cutter head *For more details, please refer to the PDF document or feel free to contact us.
