Pre-stressed anchor cable structure and construction method
The invention relates to a pre-stressed anchor cable structure and a construction method, and relates to the technical field of civil construction, the pre-stressed anchor cable structure comprises a plurality of steel strands, each steel strand comprises an anchoring section and a free section which are located on the inner side and the outer side of a mounting hole, a fixing device is arranged on each anchoring section, and each fixing device comprises a fixing support and a wire bundling disc which are arranged on the multiple steel strands in a sleeving mode; the fixing supports and the bunching discs are arranged at intervals, and the steel strands located between the adjacent fixing supports and bunching discs are in an inclined twisting state. The steel strand, the fixing support and the bunching disc are installed in the installation hole to form the anchoring section, then the concrete is added into the installation hole, and therefore the length of the steel strand located in the concrete is increased through the inclined and twisted steel strand, when the inclined and twisted steel strand is pulled, extrusion component force is formed between the steel strand and the concrete, and therefore the anchoring effect is improved. Therefore, the stability of the anchoring section is improved, and the reinforcing effect of the anchor cable on the side slope is improved.
本申请涉及一种预应力锚索结构及施工方法，涉及土木建筑的技术领域，包括多根钢绞线，钢绞线包括位于安装孔内外两侧的锚固段、自由段，锚固段上设置有固定装置，固定装置包括套设在多根钢绞线上的固定支架和束线盘，固定支架和束线盘间隔设置有若干个且位于相邻固定支架和束线盘之间的钢绞线呈倾斜扭曲状态。本申请通过将钢绞线、固定支架和束线盘安装到安装孔中形成锚固段，然后向安装孔内添加混凝土，因此倾斜扭曲的钢绞线增大了位于混凝土内钢绞线的长度，而倾斜扭曲的钢绞线受到拉力时，使得钢绞线与混凝土之间形成挤压分力，从而增大了锚固段的稳定性，提高了锚索对边坡的加固效果。
