AI Technical Summary
Technical Problem
The existing shield tunnel segment structure is connected by bolts, which results in poor overall support system integrity, large stress at the joints, easy damage, and reduced overall service life.
Method used
The tunnel segments are connected in both circumferential and axial directions by using a combination of prefabricated insert components and prefabricated slot components, along with I-beams and connecting plates. This avoids the use of bolt holes, disperses the surrounding rock pressure, and enhances connection stability.
Benefits of technology
It improves the overall stability and stress capacity of the shield tunnel segment structure, reduces the probability of damage at the joints, and extends the service life.
