Road and bridge crack reinforcing structure

Abstract

The invention discloses a road and bridge crack reinforcing structure which comprises a crack repairing structure, the crack repairing structure comprises a roadbed to be repaired, a crack open groove is formed in the top face of the roadbed to be repaired, and a trapezoidal open groove, a slit open groove and a cylindrical open groove are formed in the bottom face of an inner cavity of the crack open groove; through the prestress applying structure, people can apply traction stress to the prestress energy storage mechanism under the assistance of a tool, traction stress can be applied to the fixing mechanism through the prestress energy storage mechanism, downward traction stress can be applied to the reinforcing component through the fixing mechanism, and the effect of fixing the reinforcing component is achieved; meanwhile, the reinforcing component and the fixing mechanism cannot be abraded due to mutual friction in the vibration process, the service life can be prolonged again, the prestress applying structure can be limited through the prestress locking mechanism, in this way, the traction stress borne by the reinforcing component is fixed, and the practicability of the road and bridge crack reinforcing structure is improved.

Description

technical field [0001] The present invention relates to the field of crack reinforcement structures, and more particularly, to crack reinforcement structures of roads and bridges. Background technique [0002] Road and bridge are generally composed of subgrade, pavement, bridge, tunnel engineering and traffic engineering facilities. Subgrade engineering, subgrade is a linear structure built with soil or stone, which bears its own rock and soil weight and road surface gravity. , and the traffic load transmitted from the road surface, is an important part of the entire highway structure. The road subgrade mainly includes several parts such as the subgrade body, the side slope, the side ditch and other auxiliary facilities. The road material or mixture is layered on the road subgrade for the car to run. Its function is to ensure that the car can run all-weather, stable, high-speed, comfortable, safe and economical on the road. The road is usually composed of the road surface. ...

Problems solved by technology

[0003] There are many existing methods for repairing cracks in roads and bridges, among which the filling and repairing method is the most used and fastest repairing method. When repairing, a deep groove is cut out along the crack first, and then cement mortar, epoxy mortar, etc. are embedded in the groove. Adhesive materials such as asphalt and reinforcing agent can be repaired after the adhesive material is solidified, but the degree of adhesion between the filler and the original roadbed is not high, and it is easy to be damaged and fall off in subsequent use. Install a rigid bearing plate to strengthen and protect it, but the reinforcement effect is poor. The rigid bearing plate is generally installed on the road surface through bolts or expansion nails. The bolts or expansion nails are directly exposed to the outside and are easily corroded and broken, causing the rigid bearing plate to fall off. , the service life is short, and the passing vehicles will impose intermittent loads on the rigid bearing plate. This load will cause the rigid bearing plate to bear vertical force and lateral force. The lateral force is formed by the friction between the wheel and the rigid bearing plate Yes, due to the elasticity of the roadbed, the vertical force on the rigid bearing plate will cause the rigid bearing plate to move downward relative to the bolts or expansion nails, the vertical force will disappear, and the roadbed will rebound and move upward with the rigid bearing plate, which will cause the rigid bearing plate to move downward. The plate vibrates up and down under the intermittent load, and the lateral force on the rigid bearing plate will cause it to vibrate laterally in the driving direction. The lateral vibration will cause the rigid bearing plate to hit the bolt or expansion nail, resulting in a gap between the rigid bearing plate and the bolt or expansion nail. Mutual friction and impact will not only wear itself, but also wear bolts or expansion nails. The rigid bearing plate will fall off after serious damage, and the bolts or expansion nails will fall off, and the service life is short. Therefore, it is urgent to design a crack reinforcement structure for road bridges.
