For example, if three kinds of raw materials are required for repairing the road surface, three storage tanks 6 are sufficient. In order to ensure that it is applicable to all road surfaces, the pavement engineering rapid repair device of the embodiment of the utility model can be provided with multiple storage tanks 6 to meet the needs of different road surface repairs. Figure 1 In a specific implementation, the storage tanks 6 in the embodiment of the utility model can be arranged in a row inside the vehicle body 10, and of course can also be arranged in two rows, etc., and the utility model does not make specific limitations on this.

[0056] In specific implementation, the microwave heating device 8 in the embodiment of the utility model includes a magnetron and a bell mouth, wherein the magnetron is used to excite microwaves; the bell mouth is used to concentrate and transmit the microwaves transmitted by the waveguide downward to heat the repair area on the road surface, so that the slurry in the repair area can quickly coagulate and harden.

[0057] In addition, in the specific implementation, in order to ensure the quality of the final slurry mixing, the embodiment of the utility model sets a plurality of uniformity detectors in the stirring pot 3 to detect the uniformity of the slurry in the stirring pot 3, and sends the detection results to the controller 18, so as to control the construction after the slurry is evenly mixed through the controller 18. Specifically, the embodiment of the utility model can set three uniformity detectors, and the uniformity detectors are evenly distributed on the side wall of the stirring pot 3 along the center line direction of the stirring pot 3, so as to maximize the uniformity of the slurry, thereby obtaining better road repair quality.

[0058] It should be noted that, in order to obtain different water temperatures, the embodiment of the utility model can also be provided with multiple solvent boxes 2. The specific number and location of the solvent boxes 2 can be set by those skilled in the art according to actual needs, and the utility model does not make specific restrictions on this. Figure 2 shown.

[0059] Then, during the specific implementation, the embodiment of the utility model can further be provided with a geotextile spreader 13, which includes a roller 14 and a geotextile 15, the two ends of the roller 14 are fixed on the vehicle body 10, and the roller 14 can rotate around the central axis of the roller 14, and the geotextile 15 is wound around the roller 14, and the roller 14 can rotate, so as to spread the geotextile 15 in the repair area according to the needs of the repair construction, and spray the heated solvent in the solvent box 2 onto the spread geotextile 15 to keep the repair area warm and moist.

That is, when the repair time is short and the repair area is large, and the microwave heating device 8 cannot continue to heat, the geotextile 15 can be spread in the repaired area, and water can be sprinkled through the sprinkler head 12 to achieve heat preservation and moisturizing maintenance. Specifically, the water sprinkled in the utility model contains antifreeze to prevent the water from freezing in a negative temperature environment and failing to achieve moisturizing.

[0060] In order to make the solvent, ie, water, flow out as quickly as possible, the utility model can also set a pressure-boosting device at the connection position between the solvent box 2 and the water pipe 11 to facilitate the outflow of water.

Different quantities are first stirred in the common storage tank 6, and then introduced into the stirring pot 3. This method of mixing the materials in advance saves the stirring time of the stirring pot 3, so it can effectively save the overall construction time and improve work efficiency.

Considering the tight repair task, when the repair device needs to be moved to the next repair area, the geotextile spreader 13 is used to achieve heat preservation and moisture retention. Under negative temperature conditions, water will freeze. In this regard, the utility model prevents water from freezing by using micron heating and adding antifreeze to ensure that liquid water can be maintained when the device is not working, when the repair material is hydrated and condensed, and when watering and moisturizing maintenance.

[0083] In addition, the embodiment of the utility model is provided with 3*2=6 microwave heating devices 8 and radiation cavities 9 at the bottom of the bottom plate. The microwave heating device 8 is composed of a magnetron, a waveguide and a horn. The magnetron excites microwaves, which are transmitted through the waveguide, and the horn allows the microwaves to be concentrated and transmitted downward. The repaired repair area is heated by the microwave heating device 8, thereby promoting the rapid coagulation and hardening of the repair material. The radiation cavity 9 is also used to concentrate microwaves for downward transmission and heating to improve the addition efficiency. In addition, in order to obtain a better heating effect, the embodiment of the utility model is arranged with infrared auxiliary heating lamps 20 around the inner periphery of the radiation cavity 9.

[0084] A geotextile spreader 13 is also provided on one side of the vehicle body 10 of the embodiment of the utility model, which mainly includes a roller 14, a geotextile 15 and a water pipe 11. When the repair time is short and the repair area is large, and heating cannot be continued, the geotextile 15 can be spread in the repaired area, and water can be sprayed through the spray head 12 to achieve heat preservation and moisture maintenance. The water sprayed contains antifreeze to prevent the water from freezing in a negative temperature environment and failing to achieve moisture retention.

[0085] The utility model utilizes the characteristics of microwave heating, which is efficient, fast and environmentally friendly, and adopts a microwave heating device to heat the repair area, accelerate the coagulation and hardening of the repair material, shorten the repair time, improve the repair efficiency, and overcome the disadvantage of slow coagulation and hardening of the repair material under negative temperature environment. In addition, the device adopts a multi-wave source microwave heating array combination method, and improves the heating efficiency through mutual coupling between the microwave sources, and overcomes the disadvantage of the heating blind area in single wave source heating. By adding a radiation cavity on the outside of the microwave heating device, the heat is concentrated and transmitted downward to reduce heat loss. In addition, the device is connected to the antifreeze tank through a water storage tank, and antifreeze is added to the water to prevent ice formation, so that liquid water can be maintained when the device is not working, when the repair material is hydrated and condensed, and when the geotextile is laid to sprinkle water for moisture retention. The device controls the heating of the storage tank and the addition of raw materials to the stirring pot through sensors, which is simple to operate, easy to use, and avoids heat loss. And when the repair task is tight, when the device needs to repair the next area, the geotextile can be laid through the geotextile spreader to keep the repair material warm and moisturized to keep the repair material continuously hydrated.

[0086] Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, and thus, the scope of the present invention should not be limited to the above embodiments.
