Ultra-high performance concrete duct piece
The invention provides an ultra-high-performance concrete duct piece which comprises a duct piece body, the duct piece body is made of ultra-high-performance concrete, at least two bolt holes are formed in each of the periphery of the duct piece body, a plurality of bolt grooves are formed in the bottom of the duct piece body, and the bolt holes correspond to the bolt grooves in a one-to-one mode. The two ends of each bolt hole extend to the side wall of the pipe piece body and the groove wall of the corresponding bolt groove, a steel bar assembly is arranged in the pipe piece body and composed of frame steel bars and reinforcing steel bars, the frame steel bars are arranged along the edge of the pipe piece body, and the reinforcing steel bars are arranged around the bolt holes and the bolt grooves. The ultra-high-performance concrete is used as a main body material of the segment, the characteristics of high compression resistance, tensile resistance and fracture resistance and high toughness of the ultra-high-performance concrete material are utilized, the soil pressure and water pressure resistance of the segment is enhanced, only a small number of steel bars are arranged, the material consumption is reduced, the dead weight of the segment is reduced, and hoisting, transportation and construction of the segment are facilitated.
本发明提供了一种超高性能混凝土管片，包括管片本体，管片本体的材料为超高性能混凝土，管片本体的四周各设有至少两个螺栓孔，管片本体的底部设有多个螺栓槽，螺栓孔与螺栓槽一一对应，螺栓孔的两端延伸至管片本体的侧壁和螺栓槽的槽壁，管片本体内设有钢筋组件，钢筋组件由框架钢筋和加强钢筋组成，框架钢筋沿管片本体的边缘设置，加强钢筋设置在螺栓孔和螺栓槽的周围。本发明以超高性能混凝土作为管片主体材料，利用超高性能混凝土材料抗压、抗拉、抗折能力强、韧性高的特点，增强了管片抵抗土体压力和水压力的能力，只配有极少量的钢筋，减少了材料用量，降低管片的自重，方便管片的起吊、运输和施工。
