This invention belongs to the field of concrete building materials technology, and discloses a fiber-reinforced concrete segment suitable for dual control of micro-cracks and macro-cracks, and its preparation method. The fiber-reinforced concrete segment comprises cement-based concrete and crack-resistant fibers and structural fibers compositely added to the cement-based concrete. The crack-resistant fibers are fine steel fibers with a diameter of 0.15-0.25 mm and a length of 10-15 mm; the structural fibers are coarse polypropylene fibers with a diameter of 0.8-1.2 mm and a length of 40-60 mm; the volume fraction of the crack-resistant fibers is 0.5%-0.8%; and the volume fraction of the structural fibers is 0.5%-0.9%. The fiber-reinforced concrete segment provided by this invention can achieve continuous crack control, synergistic effect, and better economic efficiency.

The utility model relates to a discharging device technical field, specifically disclose a kind of anti -blocking discharging device. Among them, including upper pipeline structure, lower pipeline structure, heating structure being arranged on the upper pipeline structure and the lower pipeline structure, filter structure being arranged between the upper pipeline structure and the lower pipeline structure and the broken material structure being arranged above the filter structure, the heating structure is used to heat the material liquid in the upper pipeline structure and the lower pipeline structure, the agglomerate in material liquid can be intercepted by the filter structure, the broken material structure can break agglomerate. The utility model effectively solves the problem of blocking and agglomeration in the adhesive discharging process, improves the discharging efficiency and product quality.
