Abstract

The invention discloses a preparation device and preparation method of a bridge deck with an in-situ detection function. The preparation device comprises a composite surface layer with the in-situ detection function, a foam sandwich layer and a lattice web, wherein a carbon nanotube interface sensor is implanted into the surface layer of the bridge deck, the carbon nanotube interface sensor and the bridge deck are integrally formed at one time through a vacuum assisted molding process, so that the integrity of the composite surface layer and a core material is improved through the lattice web,the mechanical property of the bridge deck is improved, and the bridge deck built by traditional concrete and steel structure materials has the defects of being large in dead weight, prone to corrosion and the like. The bridge deck has the advantages of light weight, high strength, salt resistance, corrosion resistance, reduction of structural maintenance cost, industrialized production, field assembly and the like, and can be widely applied to various bridge projects.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a bridge deck preparation device with an in-situ detection function and a preparation method thereof. Background technique [0002] The composite material sandwich structure is composed of upper and lower composite material surface layers, lightweight core materials, and lattice webs. The core materials mainly include honeycomb core materials and polyurethane foam core materials. Compared with the traditional concrete bridge deck, it undoubtedly reduces the self-weight of the bridge deck and improves the durability. Compared with ordinary composite material laminates, the sandwich structure can greatly improve the mechanical properties of the structure with a small weight gain. , and the lattice web can strengthen the connection between the composite surface layer and the intermediate foam core material, and play an anti-stripping role. The core material mai...
