Rapid sealing and reinforcing device for road expansion joint

Abstract

The invention discloses a rapid sealing and reinforcing device for road expansion joint. The device comprises a boundary beam reinforcing device which includes a movable unit and a fixed unit; a first groove is formed in the end face of the edge beam, and the movable unit is arranged in the first groove; the fixing unit comprises a fixing plate, and the fixing plate is of an inverted L-shaped structure; second grooves are formed in the top ends of the fixing plates; the sealing device comprises a top cover plate and a bottom supporting plate, wherein the two ends of the top cover plate are clamped in the second grooves respectively; the bottom supporting plate is connected between the fixing plates; the bottom supporting plate comprises a main plate and sub-plates symmetrically arranged on the two sides of the main plate, and the main plate and the fixing plate are integrally formed; a cavity is formed in one side of the main board, one side of the sub-board is arranged in the cavity, and an elastic connecting piece is arranged between the main board and the sub-board; supporting blocks are arranged at the top ends of the main plates; and the control monitoring module comprises a controller and a stress monitoring module. By means of an integral embedding mode, the sealing and reinforcing efficiency of the road expansion joint is greatly improved, and meanwhile great convenience is brought to later maintenance and replacement.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a rapid sealing and reinforcing device for road expansion joints. Background technique [0002] Road expansion joints refer to the fact that in order to meet the requirements of concrete deformation, expansion joints are usually set between two girder ends, between girder ends and abutments, or at the hinged position of bridges, so that the road surface can be stretched horizontally along the long direction and can be stretched at a certain level. It is free to expand and contract within the range, and it is firm and reliable. In order to ensure the normal passage of vehicles, a sealing reinforcement device should be installed in the road expansion joints. While ensuring the horizontal expansion of the road surface, it can avoid water accumulation or unnecessary garbage accumulation in the expansion joints, but use The sealing and strengthening device of the expansion j...

It is free to expand and contract within the range, and it is firm and reliable. In order to ensure the normal passage of vehicles, a sealing reinforcement device should be installed in the road expansion joints. While ensuring the horizontal expansion of the road surface, it can avoid water accumulation or unnecessary garbage accumulation in the expansion joints, but use The sealing and strengthening device of the expansion joint in the road has the problems of laborious and time-consuming installation and inconvenient maintenance, which is not conducive to improving the efficiency of sealing and strengthening the expansion joint of the road
