The invention discloses a novel concrete support for supporting a deep roadway and a construction method thereof. The novel concrete support includes a flexible pipe, cross beam hoops, cross beams and concrete; the flexible pipe is once-formed by an earthwork mold bag and carbon fibers so as to restrain concrete, wherein the carbon fibers are stuck to an inner side of the earthwork mold bag, a grouting opening is formed in the bottom of the flexible pipe, and the inner part of the grouting opening communicates with the flexible pipe; all the frame vertical surface supports are connected to form a unit through the cross beam loops and the cross beams; the cross beam loops sleeves the flexible pipe and are distributed at equal intervals; and the cross beams are clamped by cross beam openings of the cross beam hoops to connect all the frame vertical surface supports. The novel concrete support for supporting the deep roadway is high in support strength, is simple in structure, is easy to carry and assemble, is f
