Description
Technical field
The present invention relates to the technical fields of geotechnical engineering especially underground engineering conduit mortar depositing construction, more particularly to one kind
Assembled grouting pipe voluntarily slurry stop.
Background technique
With the rapid development of economy, the construction scale that geotechnical engineering includes underground engineering is growing.Geotechnical engineering is applied
The weak rocks soil body or seepage action of ground water are frequently encountered during work or even gush out problem (such as side slope, foundation pit, tunnel, subway, mining
And the Rock And Soil of other underground chambers etc. is reinforced or sealing), the mode for generalling use conduit slip casting reinforces Rock And Soil or intercepts ground
It is lauched.
Traditional conduit grouting method need to process slip casting slurry stop in engineering site, such as soft with slip casting in tail end of conduit
It is welded to connect steel pipe and switch gate valve between pipe, needs to cut joint steel pipe and switch gate valve after slip casting.Due in engineering
The particularity of slip casting, no matter install, be welded or cutting operation be exposed to Rock And Soil do not complete supporting crag under, working space
It is limited, the field operation time is long, risk is larger, in underground engineering weak surrounding rock paragraph, the risk to collapse is larger, in some instances it may even be possible to
Cause the safety accidents such as collapse and cave-in.In addition often there is gas, scene electric welding or cutting operation in coal measures or hydrocarbon formations
There are great security risks.Meanwhile conduit uses merely traditional slurry mode of stopping such as Anchor Agent blocking to run with hell junction
It is serious to starch spillage so that design requirement is not achieved in grouting quality, Rock And Soil consolidation effect or water plugging effect, while also result in compared with
Big waste.Therefore, a kind of safe and efficient, economic, convenient assembled conduit grouting device is needed.
Summary of the invention
The purpose of the present invention is to provide a kind of assembled grouting pipe voluntarily slurry stops, to improve conventional catheters slip casting
Method need to process the technical problem that the slip casting slurry stop bring field operation time is long, risk is big in engineering site.
To achieve the above object, the present invention provides a kind of assembled grouting pipe voluntarily slurry stop, including grouting pipe,
