Because the manhole openings are different and the sizes are different, the underground pipeline is interconnected on all sides, the toxic gas removal process is slow, and the toxic gas removal effect is not satisfactory. Therefore, the environment in the manhole is poor, and the sanitation workers working in the manhole are prone to cyanogen sulfide poisoning. SUMMARY

[0003] The present application adopts a hollow pipe sealing air bag technology, sets a TPU air bag on the outer diameter surface of a hollow metal pipe, sets a metal pipe sealing cover on both ends of the hollow metal pipe, and makes the existing traditional repair air bag. According to needs, a metal pipe vent cover is set on both ends of the hollow metal pipe, a blow-suction air hard pipe (24) is inserted into the hollow pipe sealing air bag, a blow-suction air soft pipe (25) is fixed on the hook ring (16) of the metal pipe vent cover by a hanging ring hook (26), and high-efficiency ventilation is performed on the underground pipeline at both ends of the hollow metal pipe (1). A blower is used to efficiently transport fresh air from the ground to the workers working in the underground sewage pipeline between the A well opening and the B well opening. An exhaust fan can be used to bidirectionally suck and discharge toxic gas from the sewage pipeline at the A well opening and the C well opening before and after the B well opening, so that the workers working in the B well opening and the underground sewage pipeline cannot breathe toxic gas, effectively avoiding cyanogen sulfide poisoning of sanitation workers working in the manhole.
