Abstract

The invention relates to the technical field of tunnel protection, in particular to a protective shed frame. The protective shed frame comprises a plurality of protective nets and a plurality of supporting frames; the supporting frames are arranged to be arch-shaped, and the multiple supporting frames are arranged at intervals in the longitudinal direction; a plurality of first connecting pieces are respectively arranged at the tops and the two side parts of the plurality of supporting frames in a penetrating manner in the longitudinal direction so as to connect the plurality of supporting frames; the plurality of first connecting pieces are distributed at intervals; a plurality of second connecting pieces are respectively arranged at two side parts of the plurality of supporting frames inthe longitudinal direction so as to connect the plurality of supporting frames; the plurality of second connecting pieces are distributed at intervals, and the positions of the first connecting pieces are higher than those of the second connecting pieces; and a protective net is arranged between every two adjacent supporting frames and located below the corresponding first connecting piece, the positions of the protective nets are higher than those of the second connecting pieces, and the protective nets are used for preventing broken concrete of the tunnel from falling off. The invention aims to provide the protective shed frame for preventing broken concrete from falling off.

Description

technical field [0001] The invention relates to the technical field of tunnel protection, in particular to a protective scaffolding. Background technique [0002] After the tunnel is built and put into use, the concrete in some places of the lining will fall off. There are many reasons for this problem, for example: the concrete of the lining layer vibrates due to the running of the train; the geological activities around the tunnel cause the vibration of the concrete lining layer; the natural shedding of the concrete lining layer, etc. The detachment of lining layer concrete may cause injury to construction personnel, maintenance personnel or traffic facilities, posing potential safety hazards. Therefore, it is necessary to prevent the concrete fragments falling from the concrete of the lining layer from falling, so as to eliminate potential safety hazards. Contents of the invention [0003] The object of the present invention is to provide a protective scaffold for pre...
