The utility model relates to a frame roof beam equipment technical field especially relates to a drainage lattice frame roof beam and drainage lattice frame roof beam bank protection. Crossbeam and a plurality of vertical perpendicular roof beam of placing that drainage lattice frame roof beam was placed including a plurality of levels that are located the coplanar, the crossbeam is the cross with perpendicular roof beam and forms a plurality of lattice frame beam elements that are the matrix and arrange, pre -buried in the crossbeam have a transverse drainage pipe that vertical inlet tube of placing and level placed, it pre -buriedly in the roof beam has a vertical vertical drainage pipe of placing to erect, the upper end opening setting of inlet tube just communicates with the external world, lower extreme and transverse drainage pipe intercommunication, the transverse drainage pipe communicates at the cross section with the vertical drainage pipe each other, the bottom of vertical drainage pipe is provided with the outlet. Drainage lattice frame roof beam bank protection includes above -mentioned drainage lattice frame roof beam. Above -mentioned drainage lattice frame roof beam and drainage lattice frame roof beam bank protection has solved the current problem that lattice frame roof beam supprot effect is poor, and its technological advantages that have higher stability, novel structure.
