Appearance, which leaks etc. some, in emergency circumstances seems even more important.In order to reduce shadow of the municipal rain sewage network to underground engineering construction
It rings, practices well is to need to take servant in well to build brick or air bag blocking pipe by laying bricks or stones, builds brick by laying bricks or stones often by manifold pressure
It is bad to influence plugging effect, air bag blocks again because of Operating Pressure, and personnel are detained the time in well and too long, cause construction and personnel risk
It is larger.
For the problems in the relevant technologies, currently no effective solution has been proposed.
Utility model content
For above-mentioned technical problem in the related technology, the utility model proposes a kind of duct closing type devices, can not only
The duct closing type device that different-diameter is used according to caliber difference can repeat to realize safety and efficiently plugging effect
It utilizes, while reducing and blocking cost and saving blocking time.
To realize the above-mentioned technical purpose, the technical solution of the utility model is realized in：A kind of duct closing type device,
Including outer sleeve, it is connected with inner sleeve by jack inside the outer sleeve, the outer sleeve and inner sleeve are hollow
Structure, the housing drum outer wall are connected with several wheel hubs by fastener, and tire is arranged on the wheel hub, is set on the tire
There are valve, the outer sleeve to be equipped with air-filled pore corresponding with valve, the very heavy top/bottom part is equipped with oil pipe, the outer sleeve
It is equipped with pore corresponding with oil pipe, is equipped with water outlet in the middle part of described outer sleeve one end, the water outlet is connected with relief tube.
Further, the jack and tire are connected with numerical control screen respectively.
Further, the outer sleeve and inner sleeve barrel shape are circle ring column.
The beneficial effects of the utility model：The duct closing type device of different-diameter can not only be used according to caliber difference,
It to realize safety and efficiently plugging effect, and can reuse, while reduce and blocking cost and saving blocking time.
