The modification of the tricycle mainly lowers the baffles around the compartment and increases the partitions inside the compartment, so as to realize the placement of the remaining grouting and compacting mechanisms 2, the generator set 3 and the spraying mechanism 4. The generator set 3 mainly provides working power for the traveling device 1, the grouting and compacting mechanism 2 and the spraying mechanism 4.

[0028] In an embodiment of the present invention, the grouting and compacting mechanism 2 is composed of a grouting pipe 201, a heating device 202, a pressure pump 203, and a storage tank 204. A controller 5 for controlling the operation of the grouting and compacting mechanism 2 is installed on the top of the storage tank 204. The controller 5 is provided with a light display button 501, a switch 502 and a display screen 503. The light display button 501 and the display screen 503 are used to monitor and set the working status of the grouting and compacting mechanism 2 and the spraying mechanism 4; the heating device 202 is arranged at intervals at the bottom of the storage tank 204, and the heating device 202 uses electric heating to evenly distribute the heating tubes around the bottom of the storage tank 204. A pressure pump 203 is installed on one side of the storage tank 204, and the pressure pump 203 is connected to the grouting pipe 201; the storage tank 204 is used to store asphalt raw materials that need grouting construction. After the asphalt raw materials are heated by the heating device 202, they are transported to the grouting pipe 201 by the pressure pump 203 for grouting construction. During specific operation, a stirring shaft 405 for uniformly outputting asphalt raw materials can be installed in the storage tank 204, and the asphalt raw materials to be grouted are added to the storage tank 204. Then, the asphalt is fully heated and stirred by the heating device 202 and the stirring shaft 405 installed at the bottom. When it reaches an oil-in-water emulsion, it is ready for use. Then, the viscous asphalt is pressurized into the grouted pipe 201 by the pressure pump 203, and then the asphalt is poured into the seams to be treated, so as to achieve the asphalt bonding treatment effect. The heating and stirring of asphalt and other related conditions can be monitored and set by the controller 5.

The asphalt to be sprayed is fully stirred by the stirring shaft 405. When the viscous asphalt is heated and melted, it is dispersed in the aqueous solution containing the emulsifier in the form of tiny particles under the action of the stirring shaft 405 to form an oil-in-water emulsion, and then it can be used. The entire stirring process mainly controls the temperature and stirring time, and is displayed and set by the controller 5. The specific stirring temperature and stirring time are determined according to the asphalt grade and asphalt quality. After further stirring is completed, further spraying is carried out through the spray nozzle 401, the spraying pressure pipe 402 and other devices. If there is uneven spraying or missed spraying, it can be further sprayed and covered on the entire section through the supplementary spraying pipe 403 to ensure the construction quality.
