Description
Technical field
The utility model belongs to Tunnel Boring construction equipment field, and it is clear to be related to a kind of rubber pneumatic bag formula shield machine mud channel
Reason top plug device.
Background technique
Mud channel plays the important function for being transported into out mud in slurry balance shield machine, by what is diluted outside tunnel
In slurry transportation to excavation face, for mixing the soil sandstone digged down, then by mixed slurry transportation to tunnel Wai Chu
Reason.With the driving forward of shield machine, mud channel, which is also required to constantly lengthen, to be extended, and when lengthening extension mud channel, is needed
The mud channel of front end is shut off by valve, the pipeline that part mud sandstone is deposited on telescopic sleeve front end is had after shutting off
In, to prevent mud sandstone deposition to be set on tube wall, mud flows when influencing shield machine driving, needs the deposition in pipeline
Object cleans up.
Mud channel deposit cleaning plant is with the cleaning with sealing ring flat-plate when existing slurry balance shield machine changes pipe
Chock plug is moved forward and backward in pipeline, and the deposit in pipeline is released outside pipe, and this cleaning top plug has two in practical applications
The apparent defect of kind, first is that the tightness that top plug sealing ring flat-plate is contacted with pipeline inner wall is not easy to adjust, if cooperation tension, though
It is relatively difficult when can clean out the deposit in pipeline, but drag back top plug after the completion of cleaning, simultaneously because cooperating
Plug is pressed closer, sealing ring flat-plate abrasion is accelerated, and replacement is inconvenient；If cooperating pine, deposit in pipeline if be not easily cleaned it is clean,
Influence piping flow flow velocity；Second is that having the case where bending since top plug sealing ring flat-plate and tube wall gap are smaller encountering pipeline, pushing up
Plug moves forward or back difficulty, or even can bring very big inconvenience to deposit cleaning work there is a phenomenon where blocking top plug.
Utility model content
Problem to be solved in the utility model is to be to provide a kind of rubber pneumatic bag formula shield machine mud channel cleaning top plug
Device controls contact tightness degree of the rubber pneumatic bag with pipeline inner wall by adjusting the blowing pressure of rubber pneumatic bag, both solved
Deposit clears up sordid problem, while the Caton that prevents top to fill in again and returning and drag difficult phenomenon and occur.
In order to solve the above technical problems, the technical solution adopted in the utility model is: a kind of rubber pneumatic bag formula shield machine mud
Pipeline cleaning top plug device is starched, including pipe close inner tube, rubber pneumatic bag and two air-pocket splints, the pipe close inner tube are hollow cylinder
