Description
Technical field
The utility model is related to tunnel shield machine tunneling technique field, particularly relates to a kind of shield machine single fluid grouting pipe
Rapid translating two-liquid grouting device.
Background technology
At present, at home in existing underground tunnel project shield-tunneling construction, because complicated geology is various, shield machine should mutually have many
Type, balancing earth-pressure shielding machine is one of which.Balancing earth-pressure shielding machine is during driving, if running into rich water geology
Or there is important building in tunnel top, if shield tail shield single fluid grouting solidification may occur not in time duct piece float upward or
The problems such as ground settlement is serious, or even cave in, cause road interruption or Important building impaired, bring bad to construction party
Influence and economic loss.But shield tail shield configuration two fluid grouting pipeline, equipment price and slip casting material costliness, therefore at this
Need to configure on shield tail shield in the case of kind it is a kind of single fluid grouting can be switched to rapidly the device of two fluid grouting, in need
Switch rapidly in the stratum for noting biliquid slurries.
Utility model content
The utility model proposes a kind of shield machine single fluid grouting pipe rapid translating two-liquid grouting device, prior art is solved
Middle single fluid grouting easily solidification not in time, the problem of two fluid grouting pipeline equipment and slip casting material are expensive.
What the technical solution of the utility model was realized in：A kind of shield machine single fluid grouting pipe rapid translating two fluid grouting
Device, including slip casting block and single fluid grouting pipe, single fluid grouting pipe are connected with observation inside slip casting block on described slip casting block
Path in window, observation window is connected with single fluid grouting pipe, and the path in observation window is connected with crossover sub, crossover sub and elbow
Connection, elbow is connected with B liquid pipelines.
Described observation window is bolted to connection with slip casting block, and pad, observation window are provided between bolt and observation window
O-ring is provided between slip casting block.
Described observation window is provided with the communication in screw, the screw and observation window of screw.
The utility model is in shield machine tunneling process, when running into rich water geology or important building occurs in tunnel top
When, single fluid grouting quickly can be switched into two fluid grouting, it is ensured that slurries solidify in time, prevent duct piece float upward, slurry stream from becoming estranged ground
Table is settled.The utility model is simple in construction, easy to operate, economical and practical.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is paid
The every other embodiment obtained, belongs to the scope of the utility model protection.
As shown in Figure 1 and 2, a kind of shield machine single fluid grouting pipe rapid translating two-liquid grouting device, including slip casting block 8 and list
Liquid grout pipe 10, single fluid grouting pipe 10 is connected with observation window 4, observation window 4 inside slip casting block 8 on described slip casting block 8
Path connected with single fluid grouting pipe 10, the path in observation window 4 is connected with crossover sub 6, and crossover sub 6 is connected with elbow 7,
Elbow 7 is connected with B liquid pipelines 9.
Described observation window 4 is fixedly connected with slip casting block 8 by bolt 1, and pad 2 is provided between bolt 1 and observation window 4,
O-ring 3 is provided between observation window 4 and slip casting block 8.
Described observation window 4 is provided with screw 5, screw and the communication in observation window 4 of screw 5.
Utility model works principle is：Shield is in normal driving, and tail shield is injected by Grouting Pipe 10 to section of jurisdiction wall thickness
Mortar.When shield machine is running into rich water geology or important building occurs in tunnel top, two fluid grouting is carried out（Two fluid grouting
Essence is to inject two kinds of solution reacted rapidly in soil, plays a part of cementing and filling pore, make the intensity of soil with
Bearing capacity is improved）, to Grouting Pipe 10 inside inject A liquid, inside B liquid pipelines 9 inject B liquid, B liquid by observation window 4 note
The inside of slurry pipe 10 is mixed with A liquid, injects section of jurisdiction wall thickness.In observation window 4 during the line clogging of B liquid, dismountable screw 5 is carried out
Dredging.When without using two fluid grouting, whole pipeline is cleaned in the inside water flowing of B liquid pipelines 9.This device can be avoided in richness
Slurries are lost in the ground settlement caused in water stratum, prevented also from duct piece float upward problem, it is ensured that constructing tunnel quality.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model
Protection domain within.
