Stay cable sheath temperature self-adaptive telescopic device and stay cable
The invention discloses a stay cable sheath temperature self-adaptive telescopic device and a stay cable, and relates to the technical field of bridge stay cables, the stay cable sheath temperature self-adaptive telescopic device comprises at least two HDPE sheaths arranged along the stay cable, a gap with a preset length is reserved between the two adjacent HDPE sheaths, the HDPE sheath at the upper end is fixed with a main tower, an extension pipe is arranged at the gap of the two HDPE sheaths, and the extension pipe is connected with the stay cable sheath. One end of the extension pipe is fixedly connected with the HDPE sheath close to the main tower, and the other end of the extension pipe extends and sleeves the HDPE sheath at the lower end; when all the HDPE sheaths stretch out and draw back, every two adjacent HDPE sheaths do not make contact with each other, and the corresponding extension pipes can cover the gap between every two adjacent HDPE sheaths. According to the stay cable, free stretching and retracting of all the HDPE sheaths are achieved, buckling deformation cannot occur, each extension pipe can correspondingly cover the gap between every two adjacent HDPE sheaths, external rainwater cannot corrode a steel strand and an anchor head in the stay cable, and later maintenance is convenient.
本发明公开了一种斜拉索护套自适应温度的伸缩装置及斜拉索，涉及桥梁斜拉索技术领域，包括：沿斜拉索设置的至少两个HDPE护套，相邻两个所述HDPE护套之间留有预设长度的间隙，上端HDPE护套与主塔固定，两个所述HDPE护套间隙处的设置延伸管，所述延伸管一端与靠近主塔的HDPE护套固接、另一端延伸并套设在下端HDPE护套上；当所有所述HDPE护套伸缩时，相邻两个所述HDPE护套不接触，且对应的所述延伸管均能覆盖相邻两个所述HDPE护套之间的间隙。本发明实现所有所述HDPE护套的自由伸缩，不会出现压曲变形，每个所述延伸管能对应的覆盖相邻两个所述HDPE护套之间的间隙，外部雨水不会腐蚀斜拉索中的钢绞线和锚头，后期维修方便。
