[0002] Trenchless drainage pipe pretreatment is an indispensable part of trenchless technology, among which ventilation and dredging are the primary parts. First, the pipe is forced to be ventilated to discharge toxic and harmful gases. Subsequently, the dredging work is carried out thoroughly manually to ensure that the silt and corroded concrete in the pipe are cleaned up. The purpose of this step is to check the settlement, dislocation, and straightness of the pipe, so as to provide a basis for the subsequent determination of the pipe threading plan. Ventilation equipment is needed in this process, which can provide fresh air into the pipe, discharge toxic and harmful gases, and ensure the safety of the construction environment.

[0003] In the existing drainage pipe pretreatment, when the pipe is ventilated, the pipe and the ventilation equipment are usually sealed with tape or flanges. This sealing method is not only cumbersome, but also difficult to ensure the sealing. Insufficient sealing will cause external air or harmful gases in the pipe to enter or escape through the gaps, thereby affecting the normal operation of the ventilation equipment, and then resulting in reduced ventilation effect, and the harmful gases in the pipe cannot be effectively discharged, affecting the subsequent manual dredging steps.
