Hole, the groove of the steel member one correspond to each other respectively with the groove of steel member two and form a cavity, be all provided in the cavity
It is equipped with rubber pneumatic bag；Aeration aperture corresponding with rubber pneumatic bag is offered in the pipe joint socket end and steel member one；Position
Pipe joint socket end or pipe joint female end between two rubber pneumatic bags offer detection hole.
The adaptive replaceable pipe joint waterproof construction of the utility model is in specific works, by aeration aperture to two
Rubber pneumatic bag inflation, two sealing units form a closed cavity after rubber pneumatic bag inflation, are then located at by detection
Detection hole at closed cavity detects the airtightness of enclosure space.Steel member is respectively arranged at pipeline and connects in two sealing units
The interior side of head.With the rubber pneumatic bag being convenient for changing in sealing unit.
Preferably, the groove is arc groove, and the surface of groove is smooth cambered surface, the groove of the steel member one
It corresponds to each other to form spherical hollow space respectively with the groove of steel member two.
Preferably, one-way cock is installed in the aeration aperture and detection hole.To prevent rubber pneumatic bag internal gas respectively
Reverse backflow occurs with the medium for detecting pipe joint airtightness.
Preferably, the steel member one and steel member two are reinforced and pipe joint socket end and pipeline by WELDING STUDS respectively
The connection of connector female end.
Compared with prior art the utility model has the following beneficial effects:
Compared to traditional large diameter reinforced concrete pipe road joint using rubber ring carry out closed waterproof construction with
The problem of increase of pipeline service life, pipe joint waterproof failure caused by rubber ring aging, the utility model is using can fill
The rubber pneumatic bag of gas is closed for the progress of reinforced concrete pipiline interface, keeps good waterproof performance, adaptable；Using two
Steel member is respectively arranged at the mode of the interior side of pipe joint in a sealing unit, realizes rubber pneumatic bag in sealing unit
It is replaceable, meet pipe joint for waterproof performance long-term effect requirement.
