[0002] The pipe jacking machine is mainly composed of a rotary excavation system, a main top hydraulic propulsion system, a soil conveying system, a grouting system, a measuring device, a ground hoisting device and an electrical system. The horizontal balanced pipe jacking machine is also equipped with a mud and water treatment device; the rotary excavation system (commonly known as the "machine head") is mainly composed of a front steel shell, a rear steel shell, a cutting mechanism, a cutting disc, a cutter reducer, a mud delivery and discharge mechanism, a hydraulic power unit, a deviation correction hydraulic cylinder, a waterproof ring, a cutting head, a cutter rotating shaft, an electrical system, an automatic control system and ancillary devices; its steel shell withstands external soil pressure and water pressure, protects the safety of internal equipment and operators, and facilitates continuous cutting, lining and propulsion operations on the excavation surface; in addition, the main top hydraulic propulsion system is composed of four parts: a main top hydraulic pump, a main top hydraulic cylinder, an oil pipe and an operating table, which is the jacking propulsion device for the rotary excavation system and the constructed pipeline.

[0003] In the related art, a Chinese utility model patent with announcement number CN222046881U discloses a hydraulic deviation correction device for a pipe jacking machine, including a pipe jacking machine body, a machine head and a center of gravity adjustment structure. The machine head is connected to the pipe jacking machine body, and the center of gravity adjustment structure is located inside the pipe jacking machine body. The center of gravity adjustment structure is used to adjust the center of gravity of the pipe jacking machine body; the center of gravity adjustment structure includes an angle detection component, a gravity block and an adjustment drive structure. The angle detection component is fixedly connected to the machine head, and the angle detection component is used to detect the inclination angle of the machine head. The gravity block is located inside the pipe jacking machine body and can slide in a straight line. The adjustment drive structure drives the gravity block to move closer to or away from the machine head.

[0004] In the above-mentioned related technologies, when the head of the pipe jacking machine is offset during use, the gravity block is moved by adjusting the driving structure, and the center of the main body is adjusted to move backward, so that the front end of the main body is lifted up or pressed down, so as to adjust the head. Since the head is drilled into the soil, the outer peripheral surface of the head is in contact with the soil. Since the soil has resistance to the head, when the head is adjusted by moving the gravity block, the correction effect of the head is poor. Summary of the invention
