Crack maintenance device for road and bridge maintenance

Abstract

The invention discloses a crack maintenance device for road and bridge maintenance, the crack maintenance device comprises a device body, a moving device, a spraying device and a buffer device, the moving device is arranged at the top of the device body close to the rear side edge, and the spraying device is arranged at the bottom of the device body close to the rear side edge. The buffering device is arranged at the positions, close to the edges of the two sides, of the bottom of the device body, the buffering device comprises two guide sleeves, the two guide sleeves are fixed to the bottom of the device body, limiting grooves are formed in the two sides of each guide sleeve, and limiting blocks are slidably connected into the four limiting grooves. And the four limiting blocks are divided into two groups, and two limiting blocks located in each guide sleeve form one group, so that the problem that during actual injection of existing asphalt injection equipment, due to the fact that cracks cannot be positioned, asphalt is easily poured on a road surface in the asphalt injection process, and actual operation of people is inconvenient is solved.

Description

technical field [0001] The invention relates to the technical field of road and bridge maintenance, in particular to a crack repair device for road and bridge maintenance. Background technique [0002] Bridge maintenance has two meanings. Bridge maintenance in a narrow sense refers to the inspection, testing, evaluation, and repair and reinforcement work to ensure that the bridge is always in normal working condition. Bridge maintenance in a broad sense also includes other indirect measures taken to ensure the safe operation of bridges, such as data file management, construction of relevant systems and regulations, and establishment of emergency plans. The inspection and testing of bridges should be divided into three levels: regular inspection, regular Detection and detection triggered by special circumstances. At present, the evaluation methods of bridges are still very backward. In addition to the fatigue life evaluation methods and theories of bridges have a certain bas...
