Recyclable ultra-high performance concrete fabricated temporary pavement structure

Abstract

The invention discloses a recyclable ultra-high performance concrete fabricated temporary pavement structure which comprises a plurality of pavement slabs, the pavement slabs are ultra-high performance concrete components, mortises are arranged on the side walls of the pavement slabs, the mortises between the adjacent pavement slabs are correspondingly arranged and connected through tenons, and the tenons are steel components. The pavement slabs made of the ultra-high performance concrete have the characteristics of light weight, high strength, high durability and reusability, has stronger friction force and durability compared with a steel panel, is lighter and higher in strength compared with a traditional concrete or reinforced concrete pavement slab, and can effectively reduce the weight of the pavement slab, so that the transportation cost and the installation difficulty are reduced; the tenons are of steel structures, damage in the installation and use process can be avoided, thewhole mortise and tenon joint structure does not form an acute angle on the pavement slab, the stress concentration phenomenon is relieved, repeated utilization is achieved, the surfaces of the steelstructures are smooth, installation is convenient, and in addition, the mortise and tenon joint pieces are also installation positioning devices of the prefabricated pavement slabs.

Description

technical field [0001] The invention relates to the construction field, in particular to a recyclable ultra-high performance concrete assembled temporary pavement structure. Background technique [0002] During the construction process of housing construction, municipal engineering, and highway engineering, a large number of temporary roads need to be built for the transportation of materials and mechanical equipment, or as personnel passages. At the same time, some highway projects, especially expressway projects, due to the The location is relatively remote, and it is often necessary to build a temporary resident of the project, which also requires large-scale site hardening. Currently, most of these temporary pavements are constructed by cast-in-place. Although the integrity of cast-in-place pavements is better, the construction period is long and it is difficult When the project is demolished after completion, it is often discarded directly, resulting in a large amount o...

Problems solved by technology

[0006] The purpose of the present invention is: in view of the existing prefabricated temporary pavement steel panels in the prior art, which are prone to corrosion and have a smooth surface, it is not conducive to driving safety when used in pavement structures; concrete panels or reinforced concrete panels will lead to heavy weight of the panels, which is not easy It is convenient for transportation and installation; the structure of the connector is relatively complex, and the on-site road slab docking accuracy must be very high before the connection can be implemented, but too precise connection form often leads to stress concentration, which leads to damage during use.
