Synthetic fiber reinforced concrete shield segment and preparation method thereof
The invention discloses a synthetic fiber reinforced concrete shield segment and a preparation method thereof, and relates to the field of shield segments. The synthetic fiber reinforced concrete shield segment comprises a segment steel reinforcement framework, wherein the segment steel reinforcement framework is filled with synthetic fiber concrete; a hoisting hole is pre-formed in the bottom endof the segment; and bolt holes are pre-formed in two ends, perpendicular to the cross section, of the segment respectively. The segment has crack resistance, fatigue resistance and durability, can reduce segment damage and the number of segment micro-cracks during use, is simple in construction process and low in cost, and can be used for large-scale batch production.
本发明公开了一种合成纤维增强型混凝土盾构管片及其制备方法，涉及盾构管片领域，包括管片钢筋骨架，所述管片钢筋骨架由合成纤维混凝土填充，所述管片的底端预设有吊装孔，所述管片垂直于横截面的两端分别预设有螺栓孔。该管片具有抗裂性、抗疲劳性、耐久性，使用时可减少管片破损及管片微裂缝数量，且施工工艺简单，价格低廉，可用于大规模批量化生产。
