Ribbing hollow plate underground passage structure

Abstract

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.

Description

technical field [0001] The invention relates to a ribbed hollow plate type underground passage structure. Background technique [0002] With the development of cities and the improvement of people's living standards, the number of cars in large-scale cities has increased rapidly year by year, making urban traffic face enormous pressure. At the same time, in order to improve the urban greening rate and reduce noise and air pollution in sensitive areas of the city, urban underground passages are gradually accepted and adopted by people. Due to the increase in traffic volume, the span of the underground passage is getting bigger and bigger, the roof is getting thicker and the weight is getting bigger and bigger. The current conventional structure can no longer effectively solve the problems caused by the "large span". [0003] At present, rapidity is the key method to solve urban traffic problems, and the key to rapidity is to realize traffic flow without plane crossing. The ...

AI Technical Summary

Problems solved by technology

Therefore, in the traditional underground passage structure, when the passage span is large, the thickness of the roof is very large, which increases the weight of the roof, thereby increasing the amount of concrete masonry on the roof, making the weight of the roof account for a large proportion of the total load, resulting in The load-carrying efficiency of the roof is extremely low
