Safety protection structure for civil engineering foundation pit supporting

The invention provides a safety protection structure for civil engineering foundation pit supporting, and belongs to the technical field of civil engineering foundation pits. The safety protection structure comprises fixed anchor points, rotating shafts, supports, input pipelines and auxiliary mechanisms, the rotating shafts are rotatably connected into the fixed anchor points, the supports are rotatably connected into the fixed anchor points, and the supports are located above the rotating shafts; and the input pipelines are installed in the fixed anchor points and located at the right sides of the rotating shafts and the supports, and the auxiliary mechanisms are clamped to the tops of the fixed anchor points. According to the safety protection structure, in the using process, the fixed anchor points are embedded into anchor holes, then the fixed anchor points are in butt joint through the clamping supports, and therefore the fixed anchor points can be firmer in the anchor holes of a foundation pit; and whe
