Description
Technical field
The present invention relates to a kind of grouting device, particularly relate to a kind of shield machine shield tail and synchronize embedded biliquid note
Sizing device.
Background technology
At present, along with a large amount of constructions of domestic and international subway, tunneling shield method excavation is by feat of the advantage of self
It is increasingly becoming the Main Means of Urban Underground construction.During shield driving, after shield tail departs from section of jurisdiction,
Owing to cutterhead excavation face diameter is more than section of jurisdiction external diameter, it will cause there is gap between section of jurisdiction and stratum, tunnel,
If backfilling this space not in time, formation variation certainly will be caused, and then neighbouring underground structures is produced broken
Bad property affects.Synchronous grouting mode is generally used to suppress stratum settlement on existing shield machine, but also anti-
Only segment joint and tail gap seep water.Synchronous grouting is divided into again single liquid synchronous grouting and dual-fluid synchronous slip casting,
Existing shield machine uses single liquid synchronous grouting, but owing to single liquid synchronous grouting setting time is long, needs
Long period can coagulation forming, therefore single fluid grouting be in use likely to result in ground settlement from
And impact above ground structure, and single liquid synchronous grouting is easily diluted by subsoil water, produces material
Separating, section of jurisdiction produces rising phenomenon.
Two-liquid grouting device mainly has external (Japanese) and B liquid pipe is inserted A liquid pipe the most both at home and abroad
Middle mixing slip casting two kinds (sea Rake formula).And external two-liquid grouting device is due to prominent shield body, easily send out
Raw card shield phenomenon, therefore it is only applicable to weak soil, it is not suitable for other geology；B liquid pipe is inserted in A liquid pipe
The two-liquid grouting device operation complexity of mixing slip casting, is susceptible to liquid blockage, and practical effect is the best.
Therefore, shield-tunneling construction is needed badly one and is applicable to various geology, and simple to operate, should not block is double
Liquid grout device.

Detailed description of the invention
As shown in Figure 1 to Figure 3, the present invention includes the first valve block the 1, second valve block 2 and shield body contiguous block 3,
First valve block 1 welds with the second valve block 2, and the second valve block 2 welds with shield body contiguous block 3, the first valve block 1
Lead to being provided with corresponding A liquid passage 4, B liquid passage 5, piston channel 6 and water in the second valve block 2
Road 7, the A liquid passage 4 being correspondingly arranged in the first valve block 1 and the second valve block 2 is at the first valve block 1 and second
Valve block 2 junction is connected by A liquid seamed pipe 8 and sealing ring 9；First valve block 1 and the second valve block 2
The water channel 7 being inside correspondingly arranged in the first valve block 1 and the second valve block 2 junction by water seamed pipe 10 and
Sealing ring 9 connects.First valve block 1 end is fixed with B liquid socket 12 and piston by bolt 11 respectively
Cylinder 13, piston cylinder 13 front end is provided with mixed liquor jet, is provided with many B liquid pipes in B liquid passage 5
14, B liquid pipe 14 one end being positioned at the first valve block 1 is connected with B nozzle for liquid 15, and B nozzle for liquid 15 sets
Putting in B liquid socket 12, B nozzle for liquid 15 is positioned by B liquid socket 12, sets in piston channel 6
Being equipped with piston rod 16, piston rod 16 one end being positioned at the first valve block 1 is provided with piston 17, piston 17
Being arranged in piston cylinder 13, piston rod 16 is driven by propulsion cylinder 18, and the other end of piston rod 16 passes through
Jack connects seat 19 and connects propulsion cylinder 18, and jack connects seat 19 and is used for connecting piston rod 16 and advancing
Cylinder 18, propulsion cylinder 18 is fixed on shield body contiguous block 3 by ear mount 20.It is positioned at the first valve block 1
A liquid passage 4 and B liquid socket 12 is turned on piston cylinder 13 by the first communicating passage 21, is positioned at first
Water channel 7 in valve block 1 is turned on piston cylinder 13 by the second communicating passage 22, described piston rod
During 16 withdrawal, piston 17 blocks second communicating passage 22 opening on piston cylinder 13；Piston rod 16
