The present invention relates to a precast concrete segment which applies a frame unit set. The precast concrete segment of forming a tunnel wall (lining) when excavating a cut-and-cover tunnel or a tunnel using TBM comprises: a main body formed by depositing concrete; and one or more frame units arranged in a width direction of the main body and formed in a set to connect an adjacent precast concrete segment when a plurality of precast concrete segments are successively arranged by being arranged to be buried in the main body. The frame unit comprises: one or more first main reinforcements arranged by being extended in a longitudinal direction of the main body; one or more second main reinforcements formed in a length same as the first main reinforcement, and arranged to be separated at a set interval on a lower side of the first main reinforcement; one or more lattices which connects the first main reinforcement with the second main reinforcement, and are arranged in the longitudinal direction of the first and second main reinforcements; and combination plates fixated by being in contact with both end parts of the first and second main reinforcements. |
