Specific embodiment
The utility model is specifically described with reference to the accompanying drawings and embodiments.
Fig. 1 show the pipeline arrangement schematic diagram of the utility model.
The utility model provides a kind of novel shield machine dual-fluid synchronous slip casting system, including A liquid channel 1, and the A liquid is logical
A fluid system is accessed in 1 left end of road, is original-pack single fluid grouting system, includes 8m3Mortar jar and two SCHWING pumps, are located at No.1
On the right side of trailer, the injection for mortar during dual-fluid synchronous slip casting etc..
The utility model further includes B liquid pipeline 2, water flushing channel 3, threeway 4, pneumatic ball valve 5, check valve 6 and observation window
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, same for biliquid
The injection of waterglass, realizes the mixing of two kinds of different liquids of A, B during step slip casting.
Fig. 2 show the utility model B liquid pipeline and water flushing channel structural schematic diagram.
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
