[0002] Shield tunnel segments are a key material used in shield tunnel construction. They are mainly used to line the outer wall of the tunnel pipe, resist the surrounding soil and groundwater pressure, and protect the tunnel structure from external influences to ensure the safety and reliability of construction. There are many types of shield tunnel segments, including steel segments, precast concrete segments, corrugated steel plate segments, fiberglass segments, etc.

[0003] In the prior art, a plurality of countersunk holes are usually opened on the pipe segments, and then the pipe segments are fixed to the shield tunnel wall with bolts to withstand the pressure of the surrounding soil and groundwater.
