Tunnel pre-buried sliding groove fixer and implementation method thereof

The invention discloses a tunnel pre-buried sliding groove fixer and an implementation method thereof. The tunnel pre-buried sliding groove fixer comprises an insulating sleeve and a positioning pipe,a pre-buried sliding groove is fixedly connected with the insulating sleeve, the positioning pipe sleeves the insulating sleeve and is fixedly connected with the insulating sleeve, and the positioning pipe is fixed on a main rib through a fixing frame. The fixer is arranged to fixedly connect the pre-buried sliding groove with a reinforcing mesh, the fixer is provided with a spring, the fixer plays a role in elastically supporting the pre-buried sliding groove, and only a steel formwork needs to be compressed to be tightly attached to the pre-buried sliding groove without bolts and welding tofix the pre-buried sliding groove; and the quality problems such as steel formwork deformation caused by welding or bolt fixed connection are prevented, the construction quality is guaranteed, and the construction efficiency
