DENG LIANGYOU / LIANG GUANGCHI / DENG JINGSHENG / ZHANG YONG / HUANG DARONG

The invention relates to the technical field of pre-stressed anchor cables, in particular to an anchoring section pre-stressed anchor cable structure which comprises a mounting plate, a middle column is fixedly connected to the interior of the mounting plate, and a plurality of screws used for fixing the mounting plate are arranged in the mounting plate. A plurality of pre-stressed anchor cable bodies are fixedly connected into the mounting plate, and supports are arranged on the outer sides of the pre-stressed anchor cable bodies. According to the anchoring section pre-stressed anchor cable structure and the construction method thereof, by arranging the supporting assembly, when the pre-stressed anchor cable body is used, four supporting plates are driven to move, so that the supporting plates make contact with the inner wall of the anchor cable hole, the pre-stressed anchor cable body is supported, and the pre-stressed anchor cable body is located in the center of the anchor cable hole; and the situation that the structure of a formed concrete solidification body is unstable when grouting is conducted on the anchor cable hole due to deviation of the pre-stressed anchor cable body is reduced, and the structural strength is guaranteed.

本发明涉及预应力锚索技术领域，具体为一种锚固段预应力锚索结构，包括安装板，所述安装板的内部固定连接有中间柱，所述安装板的内部设置有数量为多个且用于对安装板进行固定的螺钉，所述安装板的内部固定连接有数量为多个的预应力锚索本体，多个所述预应力锚索本体的外侧设置有支架。该锚固段预应力锚索结构及其施工方法，通过设置支撑组件，能够在预应力锚索本体使用时，通过带动四个支撑板移动，使支撑板与锚索孔的内壁接触，对预应力锚索本体进行支撑，使预应力锚索本体位于锚索孔的中心位置，减少出现预应力锚索本体偏移而导致在对锚索孔内注浆时，形成的混凝土凝固体结构不稳定的情况，保证结构强度。
