The invention discloses a high-strength reinforced concrete pipe, and relates to the technical field of reinforced concrete pipes. A high-strength reinforced concrete pipe comprises a steel reinforcement framework and a concrete layer. The steel type of steel bars adopted by the steel reinforcement framework is BS20MnSi, the diameter of the steel bars is 24-26 mm, the steel reinforcement framework is cylindrical, and the cylindrical steel reinforcement framework is composed of longitudinal bars and annular stirrups. A production process of the high-strength reinforced concrete pipe comprises the three steps of dense mixing, centrifugal forming and curing treatment. According to the high-strength reinforced concrete pipe, in the middle section of the centrifugal process and when the reinforced concrete raw material begins to solidify, a slow-speed centrifugal mode is adopted, it is guaranteed that all components in the raw material cannot be layered under the action of large centrifugal force, and then the integrity of the overall structure of the reinforced concrete pipe is guaranteed. A corrosion inhibitor is doped into the raw material of the concrete layer, so that the effect of relieving the oxidation corrosion condition of the steel reinforcement framework is achieved, and the stability and the service life of the internal structure of the reinforced concrete pipe are guaranteed.
本发明公开了一种高强度钢筋混凝土管材，涉及钢筋混凝土管材技术领域。一种高强度钢筋混凝土管材，包括钢筋骨架和混凝土层，钢筋骨架所采用的钢筋钢种为BS20MnSi，钢筋直径为24‑26mm，钢筋骨架为筒状，筒状钢筋骨架由纵筋和环状箍筋组成，其生产工艺包括拌合密实、离心成型和养护处理三个步骤。该高强度钢筋混凝土管材，在离心过程的中段，钢筋混凝土原料港开始凝固时，采用缓速离心的方式，确保原料中各种组分不会在较大离心力作用下出现分层情况，进而确保了钢筋混凝土管材整体结构的完整，在混凝土层原料中掺入阻锈剂，起到减轻钢筋骨架氧化锈蚀情况的效果，为钢筋混凝土管材内部结构的稳定性和使用寿命提供保障。
