Rapid sealing and reinforcing device and method for highway expansion joint

Abstract

The invention belongs to the technical field of highway construction, and particularly relates to a rapid sealing and reinforcing device and method for a highway expansion joint. The toothed plates are connected to gaps of the beam plates in a bolted mode, the convex teeth between the toothed plates on the two sides are meshed, the top faces of the toothed plates on the two sides are connected with an elastic sealing gasket in a bolted mode, and water passing foamed plastic is arranged at the bottom between the beam plates on the two sides. During working, the toothed plates are isolated through the elastic sealing gaskets, external gravel is prevented from entering the space between the toothed plates on the two sides, the probability that scratches are generated due to friction between the surfaces of the convex teeth of the toothed plates and the gravel is reduced, accumulation of rainwater between the toothed plates is reduced through the arranged water-passing foamed plastic, the drying degree between the toothed plates on the two sides is improved, and the service life of the toothed plates is prolonged. Therefore, the probability of corrosion of the toothed plate is reduced, the service life of the reinforcing device is prolonged, and then the safety of a road is improved.

Description

technical field [0001] The invention belongs to the technical field of road construction, in particular to a fast sealing and strengthening device and method for road expansion joints. Background technique [0002] Highway expansion joints are one of the important components in the construction process of highway construction. The scientific management and technical level improvement of the whole process of highway expansion joints from design to construction play an extremely important role in alleviating road diseases and prolonging the use time of highways; highway expansion joints Usually between the two girder ends, between the girder end and the abutment, or at the hinged position of the bridge, the road surface can be stretched horizontally along the long direction, and can be freely stretched within a certain range to prevent factors such as temperature changes from affecting the safety of the road.

AI Technical Summary

Problems solved by technology

[0004] After the construction of the existing road expansion joints is completed, the expansion slots of the expansion joints are directly exposed to the outside, and the sand and stones on the road will gradually fill the expansion slots. Vehicles drive through the expansion joints, causing vibrations in the expansion joints and continuous grinding of sand and stones. The metal structure in the expansion joint causes a large number of scratches on the surface of the metal structure. At the same time, rainwater penetrates into the expansion joint, which accelerates the rusting speed of the scratch on the metal structure surface in the expansion joint, affects the normal expansion and contraction of the expansion joint, and even causes damage to road safety
