Gob-side entry retaining mass concrete curing device

The utility model discloses a gob-side entry retaining mass concrete curing device which comprises a plurality of steel pipes, fine holes are evenly distributed in the outer portion of each steel pipe, one end of each steel pipe is sealed and penetrates into a concrete wall, the other end of each steel pipe is provided with a three-way connector, and every two adjacent three-way connectors are communicated through a connecting pipe. Wherein the three-way connector located on the outermost side is connected with a water valve, and the water valve is connected with a water pipe. According to the gob-side entry retaining mass concrete curing device, the hydration heat crack resistance and the concrete strength of a gob-side entry retaining flexible formwork concrete wall can be improved, and the problems that an existing manual curing technology is uncontrollable, curing is not uniform and not in place, and the supporting strength of the flexible formwork concrete wall cannot reach the design strength are solved
