s4.1, repeating the steps S1-S3 until the fixation of all the support lantern rings is completed;

s4.2, fixedly connecting the reinforcing ribs 50 to the inner walls of all the support lantern rings, and fixedly connecting the two ends of the reinforcing ribs 50 to the inner walls of the dislocation pipe joints 100 respectively so as to connect all the support lantern rings;

s4.3, fixing all the dislocated pipe joints 100 is completed.

Illustratively, when the dislocation is serious and a plurality of support collars are required to fix the dislocation pipe joint 100, stable connection among a plurality of support collars can be ensured through the arrangement of the reinforcing ribs 50, so that the fixing of the relative positions of all the dislocation pipe joints 100 of the section is realized, the overall construction efficiency of jacking operation is improved, and the safe construction of the follow-up jacking operation can be ensured through the pipe joint dislocation fixing device.

It is to be understood that the above examples of the present invention are provided for clarity of illustration only and are not limiting of the embodiments of the present invention. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. Any modification, equivalent replacement, improvement, etc. which come within the spirit and principles of the invention are desired to be protected by the following claims.
