Prefabricated shield segment formed through post-pouring, segment assembly and construction method

The invention relates to a prefabricated shield segment formed through post-pouring, a segment assembly and a construction method. First grooves are formed in the first end faces of the two sides in the circumferential direction, second grooves are formed in the second end faces of the two sides in the longitudinal direction, the first grooves communicate with the second grooves, and the segment is low in machining difficulty, convenient to produce in a large scale and convenient to construct. 本发明涉及一种后浇筑成型的预制盾构管片、管片总成及施工方法，沿环向的两侧的第一端面开设有第一凹槽，沿纵向的两侧的第二端面开设有第二凹槽，第一凹槽与第二凹槽相连通，本发明的管片加工难度低，便于规模化生产，且施工方便。
