Bending-resistant prefabricated concrete pavement structure with steel fibers laid on upper layer and lower layer

Abstract

The invention discloses a bending-resistant prefabricated concrete pavement structure with steel fibers laid on an upper layer and a lower layer. The bending-resistant prefabricated concrete pavementstructure comprises a common steel fiber laying layer, a prefabricated concrete base body, a latticed steel fiber laying layer and a bottom surface ribbed steel plate, the common steel fiber laying layer and the latticed steel fiber laying layer are laid in the prefabricated concrete base body, and the bottom surface ribbed steel plate is fixed at the bottom of the prefabricated concrete base body. According to the bending-resistant prefabricated concrete pavement structure with the steel fibers laid on the upper layer and the lower layer, the steel fiber concrete base body and the bottom surface ribbed steel plate are organically combined, so that the high-toughness and high-bending-resistance prefabricated steel fiber concrete pavement structure is formed.

Description

technical field [0001] The invention relates to a steel fiber concrete pavement structure, in particular to a flexure-resistant prefabricated concrete pavement structure in which steel fibers are laid on the upper and lower layers. Background technique [0002] Cement concrete pavement has been developed due to its advantages of high strength, high rigidity and good durability, but its disadvantages are also obvious. In order to adapt to the ever-increasing traffic volume, the thickness of the cement concrete pavement is continuously increased to improve the tensile and flexural properties of the bottom of the concrete pavement slab. Therefore, the usage of cement and water has increased, and the pollution caused by the production of cement has also increased. [0003] For this reason, many scholars and experts have been exploring ways to improve the tensile properties of concrete for a long time, and proposed steel fiber concrete. Compared with ordinary cement concrete, s...

Problems solved by technology

However, during the construction of the traditional steel fiber concrete pavement, due to the messy and short steel fibers, there is a disadvantage that the steel fibers are easy to agglomerate when the concrete is mixed. On the other hand, the steel fibers are dense and will sink to the bottom during pouring. It cannot be evenly distributed in concrete, causing its performance to decline and affecting the quality of the pavement, which limits the application and promotion of steel fiber reinforced concrete pavement
