[0002] With the popularization and development of slurry balanced pipe jacking construction method in China, slurry balanced pipe jacking construction has been more and more widely used in engineering construction. It is a trenchless construction technology that solves the damage to urban buildings and road traffic congestion during pipeline construction. In underground pipeline laying projects, slurry balanced pipe jacking machines are widely used.

[0003] For example, Chinese patent CN221500170U discloses a deviation correction device for a mud-water balanced pipe jacking machine, comprising a base plate, a hydraulic cylinder is arranged on one side of the top of the base plate, a propulsion column is arranged on one side of the hydraulic cylinder, and the pipe jacking machine body is arranged on the end of the propulsion column away from the hydraulic cylinder.

[0004] When a slurry pipe jacking machine encounters a harder area in the soil during the pipe jacking process, the machine head will deviate from the original trajectory, resulting in a deviation in the working range of the soil layer. The traditional correction structure cannot accurately sense the deviation direction and degree of the pipe jacking machine, resulting in excessive or insufficient correction. The existing positioning and correction structure has the problems of low correction accuracy and insufficient correction force, which is difficult to meet the increasingly improved engineering quality requirements and the needs of complex construction environments. To solve the above problems, a positioning and correction system for a slurry pipe jacking machine is proposed. Summary of the invention

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

A plurality of square plates 110 are connected, an inclined groove 111 is provided on one side of the square plate 110, and a sliding rod 18 is slidably installed on the inner wall of the inclined groove 111, and a correction plate 19 is fixedly connected to one end of the sliding rod 18, a plurality of hydraulic cylinders 16 are fixedly connected to a circular array on one side of the support ring 12, and a microprocessor 13 is fixedly connected to the other side of the support ring 12, a piston rod 17 is provided at one end of the hydraulic cylinder 16, and one end of the piston rod 17 is slidably connected to one end of the sliding rod 18, a pressure sensor 113, an inclination sensor 112, and a hydraulic cylinder 16 are all electrically connected to the microprocessor 13, one end of the microprocessor 13 is fixedly connected to a connecting wire 15, and an extension tube 14 is fixedly connected to one side of the support ring 12, and one end of the connecting wire 15 passes through the extension tube 14 and extends to the outside.

[0024] The following is a detailed description of the specific settings and functions of this embodiment: During the entire deviation correction process, the microprocessor 13 continuously monitors the data of multiple pressure sensors 113, and continuously adjusts the action of the hydraulic cylinder 16 to return the pipe jacking machine to the allowable deviation range near the design axis. The device can accurately sense whether the pipe jacking machine is offset through multiple pressure sensors 113 and probes 114, and can make the deviation correction force act evenly and stably on the pipe jacking machine through multiple groups of hydraulic cylinders 16, so that the pipe jacking machine can be positioned and corrected in real time and accurately, thereby improving the efficiency and accuracy of deviation correction and being able to adapt to different construction conditions. At the same time, during the advancement of the pipe jacking machine, if the deviation correction force is too large or other abnormal conditions occur during the deviation correction process, the inclination angle The sensor 112 can collect the head position and posture data of the pipe jacking machine in real time, and transmit these data to the microprocessor 13. The microprocessor 13 receives the head position and posture data of the pipe jacking machine and judges the data through an algorithm. When the head position deviation angle of the pipe jacking machine exceeds the preset value, it means that the overall direction of the head of the pipe jacking machine may be offset. The microprocessor 13 transmits the signal to the control system. The control system receives the data, thereby reminding the operator that the overall direction of the head of the pipe jacking machine may be offset, and reminding the construction personnel to check and repair, so as to ensure the safety and smooth progress of the pipe jacking construction, improve the quality and safety of the pipe jacking construction, and reduce engineering accidents and rework caused by excessive deviations.

[0025] Embodiment 2: Figure 1 - Figure 3 As shown, one end of the body shell 11 is fixedly connected to a fixing mechanism 2, and the fixing mechanism 2 includes a fixing shell 21 and an assembly flange 22.

A plurality of assembly plates 23 are welded to the outer edge of the assembly flange 22 in a circular array, and mounting holes 24 are symmetrically opened at both ends of the assembly plate 23.

[0026] The effect achieved by the entire embodiment is that when the device is installed, the mechanism is firstly sleeved on the outer wall of the pipe jacking machine so that the connecting ring 116 is located at the head position, the assembly flange 22 is fixed to one end of the fixed shell 21 by multiple fixing bolts 25, and then the assembly plate 23 is fixed to the shell of the pipe jacking machine by multiple bolts, thereby fixing the entire fixing mechanism 2 and the correction mechanism 1 on the shell of the pipe jacking machine.

[0027] The use method and working principle of the device: When the device is in use, one end of the microprocessor 13 is connected to the external control system through the connecting line 15, and multiple pressure sensors 113, inclination sensors 112 and hydraulic cylinders 16 are all connected to the microprocessor 13. During the advancement of the pipe jacking machine, when the head of the pipe jacking machine is slightly offset to one side, the head of the pipe jacking machine drives the convex ring 117 to move along the groove 115, and the convex ring 117 is squeezed onto the probe 114. When the pressure sensor 113 detects through the probe 114 that the pressure value exceeds the preset value, it indicates that the head of the pipe jacking machine has deviated. The pressure sensor 113 transmits the data to the microprocessor 13 in time, and the microprocessor 13 sends a correction instruction to the hydraulic cylinder 16. The hydraulic cylinder 16 performs a telescopic action according to the instruction, and applies a correction force to the pipe jacking machine through the piston rod 17. The piston rod 17 pushes the sliding rod 18 Moving along the inclined groove 111, the two ends of the inclined groove 111 have different heights, and the cross-section of the inclined groove 111 gradually decreases. When the piston rod 17 pushes the sliding rod 18 to move downward along the inclined groove 111, the sliding rod 18 drives the correcting plate 19 to gradually approach and squeeze the pipe jacking machine, thereby positioning and correcting the head of the pipe jacking machine. During the entire correction process, the microprocessor 13 continuously monitors the data of the multiple pressure sensors 113, and continuously adjusts the action of the hydraulic cylinder 16 to return the pipe jacking machine to the allowable deviation range near the design axis. The device can accurately sense whether the pipe jacking machine is offset through multiple pressure sensors 113 and probes 114, and the correction force can be evenly and stably applied to the pipe jacking machine through multiple groups of hydraulic cylinders 16, so that the pipe jacking machine can be positioned and corrected in real time and accurately, thereby improving the efficiency and accuracy of correction and being able to adapt to different construction conditions.

[0028] At the same time, if the correction force is too large or other abnormal conditions occur during the correction process, the inclination sensor 112 can collect the head position and posture data of the pipe jacking machine in real time, and transmit these data to the microprocessor 13. The microprocessor 13 transmits the signal to the control system. The control system receives the data, thereby reminding the operator that the overall direction of the head of the pipe jacking machine may be offset, and reminding the construction personnel to check and repair.
