Mine laneway three-dimensional lattice reinforced concrete support

A mine laneway three-dimensional lattice reinforced concrete support comprises a three-dimensional reinforcement grid structure and a concrete spray layer. The three-dimensional reinforcement grid structure is formed by connecting a top plate support and two lateral wall supports. The top plate support comprises a plurality of unit pieces and a top plate main reinforcement set composed of a plurality of parallel top plate main reinforcements, wherein the multiple unit pieces are perpendicular to the top plate main reinforcement set and are distributed in an equidistant mode. Each lateral wall support comprises a plurality of unit pieces and a lateral wall main reinforcement set composed of a plurality of parallel lateral wall main reinforcements, wherein the multiple unit pieces are perpendicular to the corresponding parallel lateral wall main reinforcements and are distributed in an equidistant mode. Each unit piece comprises a bridge-shaped arc reinforcement and a main connecting reinforcement, wherein the
