Description

Technical Field

[0001] The invention relates to the technical field of pipe jacking construction, in particular to a device for detecting direction deviation of a pipe jacking. Background Art

[0002] Pipe jacking technology is a non-excavation and dredging pipeline laying technology used in municipal construction. The advantages are that it has no impact on the surrounding environment or has a small impact, a small construction site, and low noise. It can also work deep underground, which is an advantage that excavation and burying pipes cannot match. The pipes are arranged in sections and gradually extended into the soil through a hydraulic press. Infrared laser equipment is installed on each section of the pipe for guidance. The direction of the pipe is observed during construction, thereby guiding the pipe jacking machine.

[0003] Existing devices for detecting directional deviation of pipe jacking need to adjust the angle multiple times for calibration during actual use. Some devices can rotate 180° during the detection process to check the position of both ends of the pipe, which may cause collision of the equipment, causing equipment detection failure and inaccurate data. The detection equipment needs to be installed on the inner wall of the pipe for a long time for continuous detection before the project is completed. When the pipe moves in the soil, part of the soil will enter the interior of the pipe in the form of dust through the gaps between the pipes or due to construction workers, and the outside of the equipment will be contaminated with dust or water vapor, which will affect the signal receiving device and the detection device. Dust particles may scatter infrared rays, resulting in the inability to accurately obtain the direction information of the pipe area. The longer the length of the installed pipe, the more difficult it is for the laser beam to be accurately measured in the curved channel due to the influence of the curve, and inaccurate detection will occur when detecting from a single angle. For this reason, we propose a device for detecting directional deviation of pipe jacking. Summary of the invention
