Zusammenfassung: | The utility model relates to the technical field of coal mining, and provides a flexible formwork for a coal mine gob-side entry retaining concrete column. The flexible formwork for the coal mine gob-side entry retaining concrete column comprises a flexible connecting piece and a plurality of rigid plate bodies. The rigid plate bodies are arranged at intervals in the preset direction, the preset direction is perpendicular to the length direction of the rigid plate bodies, and every two adjacent rigid plate bodies are connected through a flexible connecting piece. The rigid plate bodies are connected into a whole through the flexible connecting pieces, the number of the rigid plate bodies is controlled so that the flexible formwork can flexibly adapt to the actual situation of a roadway in an actual construction site, the formwork making size of a concrete column can meet the actual operation requirement, meanwhile, the size and weight of the flexible formwork are reduced, transportation of the flexible formwo |
