[0002] Tunnel arch support usually refers to the installation of an arch structure in an underground passage or basement area to provide support and stability. The main purpose of this support method is to firmly fix the surrounding soil layer through the arch structure, prevent the outer wall from collapsing, and form a local upper support for the basement.

[0003] Tunnel arch support reinforcement usually refers to the strengthening and reinforcement of the arch support part of an existing tunnel or underground structure to improve its bearing capacity and stability.
