Specific embodiment
The present invention will now be described in detail with reference to the accompanying drawings and examples.
Fig. 1 show pipeline arrangement schematic diagram of the invention.
The present invention provides a kind of novel shield machine dual-fluid synchronous slip casting system, including A liquid channel 1, A liquid channels 1
A fluid system is accessed in left end, is original-pack single fluid grouting system, includes 8m3Mortar jar and two SCHWING pumps, are dragged positioned at No.1
On the right side of vehicle, the injection for mortar during dual-fluid synchronous slip casting etc..
The invention also includes B liquid pipeline 2, water flushing channel 3, threeway 4, pneumatic ball valve 5, check valve 6 and observation windows 7.
The B liquid pipeline 2 is newly-increased pipeline, is located near tail shield left sides window, and B fluid system, packet are accessed in left end
The holding vessel of liquid containing B and four resistance to screw pumps of speeding are located on the right side of equipment bridge, are fixed by cover board 9 and sealing plate 10, synchronous for biliquid
The mixing of two kinds of different liquids of A, B is realized in the injection of waterglass during slip casting.
Fig. 2 show B liquid pipeline and water flushing channel structural schematic diagram of the present invention.
The B liquid pipeline 2 is embedded in tail shield shell, and the length is 600-700mm, it is 100- that radius, which is respectively welded, in both ends
45 ° of bend pipes of 500mm.
The water flushing channel 3 is newly-increased channel, is located near B liquid pipeline 2, for instead cleaning dual-fluid synchronous slip casting process
In B liquid pipeline.
The B liquid pipeline 2 and water detergent line 3 are made of 1/2 cun of seamless steel pipe.
Fig. 3 show the structural representation front view of observation window of the present invention.
Fig. 3 a show the A-A diagrammatic cross-section of Fig. 3 of the present invention.
The observation window 7 is equipped with three-port structure, including interface I, interface II and interface III, mixed for realizing A, B liquid
It closes.
The right end of the interface I of 1 right end of A liquid channel access observation window 7, the liquid pipeline 2 and water flushing channel 3 passes through
Threeway 4 merges the interface II for being connected to observation window 7.
The 7 Section III interface of observation window disposes hinged bolt, can be by the when mixed liquor solidifies
Three interfaces are dredged.
Between threeway 4 and observation window 7, check valve 6 is worked as B liquid injection A liquid for the check valve 6, pneumatic ball valve 5
In, and A liquid or mixed liquor can be prevented to be back in B liquid pipeline.
Fig. 4 show fluid system working principle diagram of the present invention.
The working principle of the invention:
