Concrete modular system based on novel fully-fabricated shear wall and construction method

The invention discloses a concrete modular system based on a novel fully-fabricated shear wall and a construction method.The concrete modular system comprises a plurality of concrete modular units, each concrete modular unit is composed of a prefabricated shear wall and a prefabricated floor slab, and the upper-layer concrete modular unit and the lower-layer concrete modular unit are connected through a vertical connecting structure; the left and right adjacent concrete module units are connected through the horizontal connecting structures, the vertical connecting structures comprise steel pipes, connecting steel bars and grouting materials, the steel pipes are pre-buried in the prefabricated shear wall in the height direction of the prefabricated shear wall, and the grouting materials are poured into the steel pipes. Connecting steel bars are arranged at the connecting joints of the prefabricated shear walls of the upper-layer concrete module units and the prefabricated shear walls of the lower-layer concre
