Ribbing hollow plate underground passage structure
The invention discloses a ribbing hollow plate underground passage structure. The ribbing hollow plate underground passage structure comprises a left wall, a right wall and a bottom plate, wherein the bottom plate is further provided with at least one partition wall. The ribbing hollow plate underground passage structure further comprises a top plate, a plurality of cavities arranged separately are formed in the top plate in the longitudinal direction of the underground passage structure, an upper thin plate, a lower thin plate and a plurality of ribbing plates are formed on the top plate, the ribbing plates are connected between every two adjacent cavities, the top ends and the bottom ends of the ribbing plates are connected with the upper thin plate and the lower thin plate respectively, and the lower thin plate is arranged on the top surfaces of the left wall, the right wall and the partition. The ribbing hollow plate underground passage structure is higher in economy, is suitable for an underground passage with an ultralarge span and reduces the self gravity of the top plate, steel bars and concrete can all effectively play the anti-tensile and anti-pressing capacity, and then the bearing capacity of the top plate is effectively improved. The internal and external temperature difference caused by heat of hydration in the concrete pouring process is reduced, and the possibility of cracks generated can be lowered with less or without cooling measures.
