The bottom surface of the top plate of the water-proof lifting cover 6 is connected to a support plate through a plurality of platform lifting hydraulic cylinders 5, and the length of the side plate of the water-proof lifting cover 6 is greater than the maximum length of the platform lifting hydraulic cylinders 5, so as to realize water-proof protection for the platform. Vertically downward telescopic water-blocking panels 2 are fixedly connected to the four surrounding of the bottom end of the support plate. A water-blocking rubber pad 1 is arranged at the bottom end of the telescopic water-blocking panel 2. The bottom end of the support plate is connected to a vehicle frame 11 through a plurality of water-blocking lifting hydraulic cylinders 4. A plurality of universal wheels 10 are arranged at the bottom end of the vehicle frame 11. A positioning lifting hydraulic cylinder 3 is arranged in the middle of the bottom end of the vehicle frame 11. A water level sensor 14 and a water pump 12 are arranged on the outer surface of the side plate of the water-proof lifting cover 6. A water suction hose 13 is detachably installed on the water pump 12.

[0030] In this embodiment, the number of the water-blocking lifting hydraulic cylinders 4 is set to 12, and the number of the platform lifting hydraulic cylinders 5 is set to 20, so as to improve the overall stability of the platform.

[0031] In this embodiment, after the telescopic water-blocking panel 2 extends downward to effectively fill the gap between the panel and the ground with the water-blocking rubber pad 1, it can play a role in blocking water, enabling workers to construct on the ground on the water-blocking side. The water-proof lifting cover 6 can block excessive water levels and protect the construction platform. A water level sensor 14 and a water pump 12 are installed on the outer surface of the water-proof lifting cover 6. When the water level is too high, drainage can be carried out through the water pump 12.

[0032] In this embodiment, the positioning lifting hydraulic cylinder 3 can position the construction platform and provide a supporting force for the construction platform.

[0033] In this embodiment, the water-blocking lifting hydraulic cylinder 4 is used to adjust the height of the telescopic water-blocking panel 2, and can also be used to initially adjust the height of the construction platform, avoiding the problems of insufficient lifting height and excessive pressure of a single-layer hydraulic cylinder.

The autonomous driving sensor system 7 and the domain controller 8 are both electrically connected to the omnidirectional wheels 10. The chassis power system 9 is used to provide power for the omnidirectional wheels 10.

[0038] The autonomous driving system uses autonomous driving sensor system 7 and domain controller 8 such as lidar, millimeter wave radar and cameras to accurately identify the vehicle's surrounding environment, autonomously avoid obstacles ahead, and control the omnidirectional wheels 10 to turn automatically. By using information technologies such as computer autonomous learning, high-precision maps, positioning, network communication and lidar, during the vehicle's autonomous driving process, it can effectively control and avoid road driving conditions, obstacles and dangers that may be encountered during driving, and cope with various complex environments and emergencies.

[0039] In this embodiment, a lighting system is further included. The lighting system includes a brightness sensor 15 and an LED light source 16. The brightness sensor 15 and the LED light source 16 are both installed on the outer surface of the water-proof lifting cover 6. The lighting system senses the change of the surrounding light intensity by the brightness sensor. When the light is weaker than the set value, the LED light source 16 automatically turns on to provide a bright environment for construction.

[0040] In this embodiment, an air quality monitoring system is further included. The air quality monitoring system includes an infrared gas sensor 17 and a grid monitoring platform 18. The infrared gas sensor 17 is used to monitor gas pollutants in the tunnel.
