Description

Technical Field

[0001] The utility model relates to the technical field of highway construction equipment, in particular to intelligent paving equipment for epoxy resin bonding layer materials. Background Art

[0002] In recent years, China's long-span bridge construction has developed rapidly, but the bridge deck is prone to early damage, especially the pavement layer. The damage of the waterproof bonding layer in the bridge deck pavement is a major cause of pavement layer diseases. Bridge deck diseases such as bulging, cracking, cracking, asphalt surface peeling, separation of asphalt surface layer from bridge deck, and corrosion of bridge main steel bars are all directly related to the bridge deck's waterproof and drainage capabilities. The design of the waterproof bonding layer is crucial in bridge deck pavement projects. In order to obtain better waterproof bonding effects, a variety of materials, technical routes or construction plans have been tested and adopted.

[0003] At present, in steel bridge deck paving projects, the typical paving structure is, from bottom to top, steel bridge deck, epoxy zinc-rich paint, waterproof bonding layer, modified asphalt paving lower layer, waterproof bonding layer, modified asphalt paving upper layer. In this structure, waterproof bonding layer is used at two interfaces. Currently, epoxy resin has excellent performance as a waterproof bonding layer and is increasingly widely used.

[0004] Epoxy resin is used as a waterproof adhesive layer. It is necessary to spread epoxy resin adhesive layer oil on the surface of the corresponding layer of the bridge. At present, the spreading of epoxy resin adhesive layer oil has not received much attention. Most of them are spread by manual roller brushing or asphalt spreading device. However, epoxy resin adhesive layer oil needs to be heated to 20-60℃ for use, and the time requirement is extremely high. The usable time at 20℃ is 45min, and the usable time at 30℃ is only 20min. Therefore, it is very important to control the temperature and spreading efficiency of epoxy resin adhesive layer oil;

[0005] Problems with the existing technology: the efficiency of manual roller painting is low, and a large amount of epoxy resin bonding oil cannot be prepared at one time for spraying. Small-scale construction easily causes the bonding oil to be unevenly heated and cooled, unevenly applied, and poor construction quality, which has a great impact on the stability of the steel bridge deck pavement. The asphalt spreading device cannot be regulated according to the temperature range unique to epoxy resin. The heating temperature of the asphalt often reaches above 160°C, and the asphalt spreading device is not cleaned properly, and the residual asphalt is easily mixed with the epoxy resin bonding oil, reducing the bonding effect.
