[0053] The cleaning device 1 is equipped with a cleaning rotary arm, a high-pressure gas nozzle and a rotating brush, is connected to the dust removal device through four rotatable joints, and is provided with six telescopic rods for controlling the cleaning equipment.

[0054] The electronic control panel 6 is fixed to the frame or supporting structure of the vehicle by screws or bolts, and is used to accurately locate the specific position of the crater and control the operation of the crawler platform 5, the cutting operation platform 4, the cleaning device 1, the spray device 2 and the water storage device 3.

[0055] Furthermore, in some embodiments of the present application, the crawler platform has an adjustable suspension system to adapt to different terrains; the bottom of the chassis of the crawler platform is equipped with a hydraulic stabilizer to ensure stability during operation; the articulated connection structure between the crawler platform and the cutting operation platform includes a rotating shaft, upper and lower hinge arms and a locking mechanism.

[0056] Furthermore, in some embodiments of the present application, a locking device and a universal joint are provided in the cleaning device, which can prevent the telescopic rod of the cleaning device from sliding and retracting at will and ensure that the telescopic rod can rotate freely for easy cleaning. The dust removal device and the ventilation duct in the cleaning device are connected by flanges and fastened with bolts and nuts.

[0057] Specifically, a flange is installed at the connecting end of the ventilation duct and the dust removal device. It is recommended that the material of the flange be carbon steel and the type be a threaded flange. This application does not make any specific restrictions on this.

[0058] Furthermore, in some embodiments of the present application, the valve type installed at the pipeline connection between the spray device and the water storage device is at least one of a ball valve, a gate valve, and a stop valve, and the valve is controlled by an electronic control panel to achieve automation; the nozzle of the spray device can achieve fine-tuning rotation, which is controlled and adjusted by the electronic control panel; the telescopic rod in the spray device is connected to the water storage device and the dust removal device through a leveling device, and supports adaptive fine-tuning of the angle, and the leveling device can maintain the connection between the telescopic rod and the water storage device and the dust removal device, which can further improve the efficiency of debris removal and watering.

[0059] In practical applications, the water storage device can make a preliminary estimate of the water demand based on the observed size of the crater. When the water storage capacity is insufficient, an additional mobile water supply vehicle can be set up.

[0060] Furthermore, in some embodiments of the present application, the telescopic rod in the spray device and the telescopic rod in the cleaning device are both high-strength telescopic rods, with the strength being sufficient to withstand the weight of transportation vehicles such as cars or airplanes.

[0061] Furthermore, in some embodiments of the present application, the water storage device contains a liquid level sensor and an electronic regulating valve, which can be jointly controlled through an electronic control panel.

[0062] Furthermore, in some embodiments of the present application, the cutting operation platform is equipped with a corresponding tool box, which has built-in electric cutting tools and laser measurement sensors. The damage notch data can be retrieved through the electronic control panel and corrected through the laser measurement sensor.

[0063] In addition, the cutting operation platform is equipped with a cutting control path and a changing system for replacing mechanical heads of different sizes and types; the cutting operation platform is equipped with a sensor control device for analyzing the input cutting shape and controlling the cutting head to cut the geopolymer concrete canvas.

[0064] It should be noted that in actual use, due to the use of automatic control and manual scanning and correction, the size of the automatically cut geopolymer concrete canvas may deviate from the actual size, so the cutting area during setting can be slightly enlarged, and manual correction and cutting can be performed when the geopolymer concrete canvas is fixed later.

[0065] In some embodiments, the fastener is an expansion bolt, which can make the fixed connection of the telescopic rod in the socket more secure. The fastener is not shown in the figure.

[0066] In the embodiment of the present application, by providing a cleaning device, debris and sundries can be cleaned from the crater and its surroundings in a short time; a spray device, a water storage device and a cutting operation platform are used to complete the cutting and spray fixing operations of the geopolymer concrete canvas for the filled crater, thereby completing the rapid repair of the panel in the damaged area. The operation is easy to implement, the structure is simple and reliable, the repair effect is good, and it is convenient and fast.

[0067] The present application also proposes a semi-automatic road surface crater rapid repair method, which is applied to the above-mentioned semi-automatic road surface rapid repair device, and comprises the following steps:

[0068] Step 101: clean the debris in the road crater using the high-pressure gas nozzle, rotating brush and dust removal device equipped in the cleaning device, and use drone imaging to obtain the shape, size, bottom depth and volume of the road crater.

[0069] In the embodiment of the present application, the electronic operation panel is operated according to the size of the pit to control the cleaning device to clean. In addition, the shape, size, bottom depth and volume of the road crater are obtained by drone imaging technology, making the information acquisition faster and replacing manual measurement to ensure personal safety.

[0070] Step 102: Use a cutting operation platform to cut the geopolymer concrete canvas to obtain a target geopolymer concrete canvas that meets the preset road surface crater size.

[0071] The present application adopts geopolymer concrete canvas to improve the shortcomings of conventional silicate cement itself, which is high in energy consumption and produces a large amount of carbon dioxide, and has the advantage of low economic cost compared with the "sulphoaluminate cement + gypsum" system.

[0072] The components of the geopolymer concrete canvas include a main three-dimensional spacer fabric, a cement matrix and a packaging material, wherein the main cement matrix is ​​a oligomer material, the three-dimensional spacer fabric is a textile woven from polyethylene and polypropylene, and the packaging material is a basalt fiber plain cloth, which are mixed according to the proportions of the known technology.

[0073] It can be understood that the cutting operation platform is equipped with a sensor control device, which can analyze the input cutting shape and control the cutting head to cut the geopolymer concrete canvas. If the crater size is large, it is necessary to select segmented cutting when selecting the cutting part on the electronic operation panel, and continuously move the cut part outward until the entire geopolymer concrete canvas is cut.

[0074] It should be noted that in actual use, due to the use of automatic control and manual scanning and correction, the size of the automatically cut geopolymer concrete canvas may deviate from the actual size, so the cutting area during setting can be slightly enlarged, and manual correction and cutting can be performed when the geopolymer concrete canvas is fixed later.

[0075] Step 103, filling the crater with polyurethane foam material.

[0076] In the embodiment of the present application, the cavity of the crater is filled with polyurethane foam material, thereby improving the cushioning and shock-absorbing properties of the repair device.

[0077] The components of the polyurethane foam material include isocyanate, polyurethane rigid foam composite polyether, and foaming agent, which are mixed according to the proportions known in the art.

[0078] Step 104: Use the cut target geopolymer concrete canvas to fill the crater position on the pavement, and fix the target geopolymer concrete canvas with edge pressing strips and expansion bolts.

[0079] In the embodiment of the present application, when using geopolymer concrete canvas for crater filling, a waterproof layer is added to the bottom of the target geopolymer concrete canvas to prevent the spray water from leaking into the rock mass below, resulting in insufficient hydration reaction of the geopolymer concrete canvas, and a layer of polyurea anti-explosion coating is added to enhance the overall anti-explosion and anti-impact performance of the geopolymer concrete canvas.

[0080] Step 105: Sprinkle water evenly from the edge to the middle of the target geopolymer concrete canvas according to the water storage device and the spraying device until the color of the target geopolymer concrete canvas becomes darker.

[0081] In the embodiment of the present application, the target geopolymer concrete canvas is sprayed by a water storage device and a spraying device, and is cured and solidified. The hardening process is monitored based on the monitoring data and results. After hardening, the geopolymer concrete canvas has good impact resistance and friction resistance, and a short solidification time.

[0082] It should be noted that when evenly sprinkling water from the edge to the middle of the target geopolymer concrete canvas, it is necessary to strictly follow the order of evenly sprinkling water from the edge to the middle, and the wetted geopolymer concrete canvas area needs to be insulated and moisturized for at least 24 hours. If its shape needs to be adjusted, it needs to be completed within the 2-hour final setting time.

[0083] In addition, the amount of spraying water should not be too much. Spraying too much water will extend the hardening time of the geopolymer concrete canvas and significantly reduce the strength obtained by hardening.

[0084] Step 106: monitor the repair and hardening process of the target geopolymer concrete canvas, and make adjustments when abnormalities occur to ensure that the specified repair effect can be achieved.

[0085] In the embodiment of the present application, the repair and hardening process of the target geopolymer concrete canvas is monitored by a monitoring system. The monitoring system used includes a laser displacement sensor, an infrared thermal imager and a humidity sensor. The hardening process of the geopolymer concrete canvas is monitored, and the parameters measured by the sensor are analyzed to respond to and repair problems arising in the hardening process in a timely manner.

[0086] The present application also proposes a semi-automatic road surface crater quick repair device for use in airports, which can repair craters on airport pavements in a short time, restore takeoff and landing of various aircraft, and can perform repairs around the clock.

[0087] It should be noted that when the present application is applied to an airport scenario, the “road surface” mentioned in the above embodiments refers to the airport pavement.

[0088] The present invention is further described below through specific examples.

[0089] Example 1

[0090] Step 1: After the airport pavement is hit by an artillery shell, clean up the debris inside and around the crater on the airport pavement, and use drone imaging to obtain measurement data such as the shape, size, bottom diameter, depth and volume of the crater on the airport pavement.

[0091] Step 2: Conduct preliminary detection and cleanup of unexploded bombs and other dangerous objects near craters on the damaged road surface.

[0092] Step 3, driving the aforementioned semi-automatic road surface rapid repair device into the corresponding damaged area, and delivering the polyurethane foam material and geopolymer concrete canvas to the crater location.

[0093] Step 4: Use a semi-automatic road surface rapid repair device to clean the crater to remove damaged fragments, collect the specific information of the crater for a second time, and verify and correct the deficiencies in image recognition.

[0094] Step 5: Spray polyurethane foam to fill the crater.

[0095] Step 6, using the geopolymer concrete canvas cutting operation platform to cut the geopolymer concrete canvas, cutting to obtain a geopolymer concrete canvas that is slightly larger than the verified size of the road surface crater size.

[0096] Step 7, use the cut geopolymer concrete canvas to fill the crater on the road surface, and fix the geopolymer concrete canvas with edge strips and expansion bolts.

[0097] Step 8, use the spray system on the semi-automatic pavement rapid repair device to evenly sprinkle water from the edge to the middle until the color of the geopolymer concrete canvas becomes darker.

[0098] Step 9, use a monitoring system to monitor the repair and hardening process of the geopolymer concrete canvas, and make adjustments when necessary to ensure that the repair effect can be achieved.
