Roadbed reinforcing device for highway bridges

Abstract

The invention relates to the technical field of roadbed reinforcing devices, in particular to a roadbed reinforcing device for highway bridges. Theroadbed reinforcing device comprises a support plate, a plurality of groups of pressure sensors are uniformly arrayed at the top of the support plate, a controller is arranged on one side of the support plate, and a first reinforcing plate and a second reinforcing plate are arranged at two ends of the support plate. A fixing plate is arranged between the first reinforcing plate and the second reinforcing plate, an inserting hole is formed in one side of the fixing plate, a supporting rod is arranged at the top of the fixing plate, multiple sets of through holes are formed in the top of the fixing plate, a first sliding rod and a second sliding rod are slidably connected into the through holes respectively, a first wedge-shaped groove is formed in the first sliding rod, and a second wedge-shaped groove is formed in the second sliding rod. According to the device, the top of the support plate can be temporarily and stably supported, the dynamic load of the top of the supporting plate can be adaptively adjusted, the supporting and reinforcing effect is improved, blockage clearing is conducted on the discharge hole, the cleanliness of the device is improved, and the drainage smoothness of the device is guaranteed.

Description

technical field [0001] The invention relates to the technical field of roadbed reinforcement devices, in particular to a roadbed reinforcement device for highway bridges. Background technique [0002] The subgrade is the load-bearing body of the road. The roadbed is composed of width, height and slope. Whether the roadbed is solid or not directly affects the service life of the road, so the roadbed needs to be reinforced after the completion of the road construction, so that the service life of the road is longer. [0003] Chinese invention patent CN202110820892.X discloses a soft soil subgrade reinforcement device, including: a first support plate, which is horizontally arranged on the surface of the soft soil subgrade, and a pair of vertical reinforcement piles are detachably arranged on the first support plate. The bottom of the reinforcement pile is inserted into the interior of the soft soil roadbed, and the top is detachably connected to the first support plate; the ...

[0003] Chinese invention patent CN202110820892.X discloses a soft soil subgrade reinforcement device, including: a first support plate, which is horizontally arranged on the surface of the soft soil subgrade, and a pair of vertical reinforcement piles are detachably arranged on the first support plate. The bottom of the reinforcement pile is inserted into the interior of the soft soil roadbed, and the top is detachably connected to the first support plate; the second support plate is arched and arranged on the first support plate and can be connected with the first support plate Disassembly and connection; reinforcement plates, which are a pair, a length-adjustable connecting rod is arranged between a pair of reinforcement plates, the bottom of a pair of reinforcement plates is detachably connected to the second support plate, and the top is inclined upward and parallel However, the structure of the subgrade reinforcement device used for the highway bridge is too traditional, and the reinforcement method cannot be quickly adjusted according to the road conditions and needs, which affects the effect of reinforcement, reduces the adaptability and flexibility of the reinforcement device, and affects the construction. Therefore, in view of the above status quo, there is an urgent need to develop a roadbed reinforcement device for highway bridges to overcome the shortcomings in current practical applications

[0004] Existing reinforcement devices for highway bridges cannot make adaptive changes according to the dynamic changes in road surface pressure during reinforcement and support, resulting in loosening of the reinforcement device and affecting the bearing effect of the road surface. At the same time, the existing reinforcement devices do not have weep holes , even if there is a drain hole, it does not have a dredging effect, which will cause water accumulation on the road and affect the drainage effect

[0005] And when the load force on the top of the support plate is different, the reinforcement device cannot adaptively adjust the support force of the support plate, so when the vehicle is constantly driving on the road surface and the load force on the top of the road surface is constantly changing, the reinforcement device itself will loosen, thereby affecting The safety performance of the entire reinforcement device
