Deep depth advancement support! Small diameter long-distance curved propulsion (mud-water method in one process)
***Leave long-distance and sharp curve construction in small-diameter propulsion to the JET method!*** The JET method is a type of propulsion construction that digs pipelines for sewage, water, gas, and electricity using a small shield machine. It is a groundbreaking method that enables long distances, sharp curves, and deep depths despite its small diameter. With the technology of the JET method, excavation from the ground is minimized, reducing noise and dust associated with construction, and minimizing road occupation. Instead of ground measurements, it uses in-pit surveying from the launch shaft with a CCD camera sensor, so it is not affected by buried objects, electric wires, or tracks. Measurements can be taken without being influenced by external factors such as under rivers, beneath railway tracks, under busy roads, and deep soil cover propulsion. 【Features】 ■ Supports high-depth propulsion ■ Simple structure and easy handling ■ Three-dimensional traverse surveying with high-resolution CCD camera sensors ■ Roll conveyor rail (patented) ■ Capable of handling a wide range of soil types For more details, please refer to the catalog or feel free to contact us.
