Background
The daily washing of conventionality is the most important ring in the bridge maintenance, and the washing of bridge mainly includes that bridge floor washs, guardrail washing, bridge expansion joint washs and the sound insulation screen washs, and the road surface washs and adopts common road sweeper to clean usually, and the guardrail cleans and also often adopts special guardrail to wash the car, and often needs the manual work to accomplish to the washing at bridge expansion joint.
Bridge expansion joints are indispensable components in bridges, and if the expansion joints are blocked, the free expansion and contraction of the bridges can be influenced, so that the service life of the bridges can be directly influenced. After the bridge is laid down, the temperature is high, the bridge temperature rises along with the temperature, the phenomenon of expansion with heat and contraction with cold can occur, the 'internal force' continuously expands outwards, and the expansion joint becomes the main space for 'dissipating force' of the bridge. If these expansion joints are blocked, the bridge "force dissipation" is affected, thereby affecting safety. The regular cleaning of the bridge expansion joints is one of the important links of the daily maintenance of the highway, the passing safety of the bridge can be guaranteed, and potential safety hazards are avoided. In a general cleaning process, a maintenance worker firstly puts a safety mark on a bridge to ensure the safety of a cleaning area. Then, the sand in the expansion joint is loosened and turned out by manually digging with a small shovel, a steel bar stick and other tools, the sand is relatively easy to clean, and if small stones are clamped, the small stones must be tilted by the steel bars. And then, a water-wheel high-pressure water gun is used for flushing the gap, and sand remained in the gap is flushed clean, so that no sundries are blocked in the gap. Finally, will on-the-spot sanitization in the lump, ensure that the silt that the clearance was come out can not fall into the expansion joint again, this process need consume a large amount of manpower and materials, once wash the staff and need bend over a hundred times, bridge floor temperature can reach fifty-six degrees in summer, be rigorous examination to the staff operation, also have certain danger in the manual cleaning process in addition, the side has the vehicle to pass through fast at any time in the cleaning process.
Chinese patent CN207176595U discloses a self-propelled bridge expansion joint cleaning vehicle, in particular to a self-propelled bridge expansion joint cleaning vehicle. Including automobile body, support, the support comprises rectangle backup pad and mounting hole, and the mounting hole is the pipe shape, and the mounting hole passes the backup pad and becomes 45 degrees contained angles with the backup pad, and support one end links to each other with the automobile body, and coincides its characterized in that with automobile body axis: the vehicle body is also provided with a walking device, and a high-pressure water jet gun body is arranged on the support mounting hole, the high-pressure water jet gun body is superposed with the central axis of the vehicle body and the central axis of the support and forms a 45-degree included angle with the vehicle body, the middle part of the vehicle body is provided with a cleaning spray gun which is vertical to the vehicle body, the spray nozzle is downward vertical to the ground, and the rear end of the vehicle body is also provided with a dirt suction device. It has been avoided the manual work to impel the operation mode of clearance specific expansion joint, has increased the operating efficiency, but this scheme often need be equipped with extra water truck, can't effectively clear up the stone in the bridge expansion joint moreover, needs to provide one kind can more thoroughly clear up the equipment of multiple debris in the bridge expansion joint.
