Description

Technical Field

[0001] The present invention relates to the technical field of pipe jacking relay chambers, and particularly relates to a rock pipe jacking relay chamber for preventing rock debris deposition and a using method thereof. Background Art

[0002] A relay chamber is a key device in long-distance pipe jacking construction, which can effectively solve the problems that the total jacking force exceeds the capacity of the main jacking cylinder and the allowable jacking force of the pipe material by jacking in sections.

[0003] In rock pipe jacking, the rock debris cut by the cutter head usually cannot all be discharged through the mud, and a part of the rock debris deposits on the top of the pipe section. As the amount of rock debris deposition increases, the frictional resistance around the pipe gradually increases, and finally exceeds the jacking force of the main jacking cylinder and the relay chamber, resulting in "pipe jamming".

[0004] At present, the main treatment methods for "pipe jamming" are to open slag cleaning holes or set up temporary relay chambers, but frequent shutdowns are required for cleaning work, which not only prolongs the construction period, but also increases the labor and material costs.

[0049] In the preferred solution, in S41, let the intensity of the i-th ultrasonic signal emitted by the radar module be I i0 , and the intensity of the signal received after passing through the cuttings layer be I i ;

[0050] Considering the non-uniformity of the cuttings and the propagation characteristics of ultrasonic waves in complex media, a correction factor β i is introduced, and the relationship between the cuttings concentration C i and the signal intensity attenuation is:

[0051]
