Description

Technical Field

[0001] The present application relates to the technical field of tunnel engineering construction equipment, and in particular to a deviation correction device for a pipe jacking machine. Background Art

[0002] The pipe jacking machine mud squeezing technology is a method of using a pipe jacking machine to construct underground pipelines. During the construction process, the pipe jacking machine uses its unique working principle to mix the mud with the soil and squeeze it out to form a stable tunnel, and then lay the pipeline in it. This technology is particularly suitable for geological conditions with soft soil, high water level and more groundwater. During the pipe jacking construction process, due to the complexity of the underground soil layer, the pipe jacking machine often encounters uneven soil resistance during jacking, causing the pipeline to deviate.

[0003] With respect to the above-mentioned related technologies, the inventor believes that the mud squeezing device used for correcting the deviation of the pipe jacking machine in the traditional technology is not convenient for the staff to adjust the angle of the pipe squeezing mud, which leads to a small scope of application and low practicality. In addition, the mud in the traditional technology is in a static state in the material box and may solidify, resulting in poor mud squeezing effect and defects. Therefore, a pipe jacking machine correction device is proposed to solve the above problems.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.
