A shield machine is a tunnel boring machine using a shield method. The shield construction method is a "shield" (referred to as a supporting segment) for constructing (laying) a tunnel while a heading machine is heading, and is different from an open construction method. Internationally, generalized shield machines can also be used in rock formations, differing only from open (non-shield) tunnel boring machines. In China, the tunnel boring machine used for the soft soil stratum is customarily called a (narrow sense) shield machine, and the tunnel boring machine used for the rock stratum is called a (narrow sense) TBM. The shield machine is generally classified into a hand-operated shield, an extrusion shield, a semi-mechanical shield (local air pressure, global air pressure), and a mechanical shield (an open-chest cutting shield, an air pressure shield, a slurry pressure shield, an earth pressure balance shield, a hybrid shield, and a special shield) according to the working principle. The basic working principle of the shield tunneling machine is that a cylindrical steel component is pushed forwards along the axis of the tunnel to excavate soil. The casing of the cylinder assembly, the shield, acts as a temporary support for the excavated, not yet lined tunnel section, bearing the pressure of the surrounding soil layers and sometimes also the groundwater pressure and the water that is trapped outside.
