An operation method of an environment-friendly cleaning vehicle for a tunnel under construction comprises the following steps:

step 1: the visual recognition system 3 detects the falling muck accumulation condition and transmits the detection result to the electric control system;

step 2: according to the accumulation condition of the muck, after being analyzed and judged by a PLC control system, a high-pressure water pump set 10 is driven by controlling a frequency converter a and a frequency conversion motor a, a control valve a is opened, a high-pressure water injection device works, and high-pressure water is injected to wash and strip the muck attached to the pipe slice;

and 3, step 3: the PLC control system drives the fan by controlling the frequency converter b and the variable frequency motor b, the fan rotates at a high speed to vacuumize the closed dustbin 12, and the stripped residue soil and sewage are sucked into the dustbin 12 through the bottom suction nozzle 13 or the handheld sewage suction pipe 14 to finish the collection work;

and 4, step 4: the PLC control system controls the frequency converter c and the variable frequency motor c to further transfer the slurry pump, and the slurry pump can transfer the residue soil and the wastewater collected in the garbage can 12 assembly into a residue soil truck carriage and convey the residue soil truck out of the tunnel;

in the embodiment, when the visual recognition system 3 recognizes that the amount of the muck dropping from the bottom of the tunnel segment is large, the frequency converter controls the rotating speed of the corresponding variable frequency motor to be increased, so that the water output of the high-pressure water pump and the air volume of the fan are improved, and the processing capacity of the slurry rotating system 6 is increased; similarly, when the slag soil that tunnel segment bottom dropped is less when discerned by vision recognition system 3, the inverter motor rotational speed that the converter control corresponds reduces, and high pressure water pump output water yield and fan amount of wind reduce, reduce the throughput of commentaries on classics thick liquid system 6, can reach the purpose of using water wisely, using electricity wisely like this to improve equipment's effective working distance.
