Specifically, after the water-soluble gas is flushed for 10min to 20min, the first air stop valve 420 and the air pump 320 are closed, the first water stop valve 710 and the second water stop valve 720 are closed, the sixth water stop valve 760 and the seventh water stop valve 770 are opened, the readings of the first flowmeter 610 and the second flowmeter 620 are observed, if the difference value of the readings is lower than a threshold value, the clogging is judged to disappear, and the cleaning is finished; if the difference between the readings of the first flowmeter 610 and the second flowmeter 620 still exceeds the threshold, it is determined that clogging exists, the value of the air pressure regulating valve is increased, and steps S200 and S300 are repeated until the difference between the readings of the first flowmeter 610 and the second flowmeter 620 is less than the threshold. Preferably, the threshold is specifically a difference of 20% between the proportions of the first flow meter 610 and the second flow meter 620.
The method for washing the blind ditch utilizes high-pressure water to wash the sediment deposited in the blind ditch, utilizes dissolved air water to wash the inner seepage passage and the outer surface of the blind ditch, opens the seepage passage and cuts up the filter cake layer. Effectively solves the clogging problem of the blind ditch, and obviously improves the drainage efficiency and the service life of the blind ditch.
Alternatively, the adapter tube 160 may be connected to the second connector 122 in the same manner, wherein the second pipe 120 serves as a water inlet or air inlet pipe, the first pipe 110 serves as a water outlet pipe, and the fourth stop valve 740 is opened during high-pressure water flushing. When the water-dissolving gas or high-pressure gas flushing is performed, the fourth water stop valve 740 is closed.
