Small diameter, long distance, curve pipe jacking
The CCD camera sensor instantly measures the TBM position with a small diameter and a sharp curve.
Not affected by underground utilities, high-voltage lines, etc.
The Jyat method has made it possible to construct long distances and sharp curves in small diameter pipe jacking.
The curve survey method involves inserting multiple CCD camera sensors into the pipe and measuring the targets in front of and behind the TBM with the CCD camera sensors. The image information sent from the sensor is calculated by the PC, and the error between planning and implementation is calculated quickly.
