Device, runner processing is complicated, and the mixing of A, B liquid is uneven, easily blocks grouting port.
The content of the invention
The present invention solves above-mentioned technical problem and provides a kind of shield machine shield tail B liquid grout nozzles, which is mounted on A slurries
Exit, structure can be such that B liquid grouts uniformly spray, and make A, B liquid uniformly quick solidification of mixing during slip casting.
The present invention solves the technical solution that technical problem uses：
A kind of shield machine shield tail B liquid grout nozzles, it includes nozzle, and nozzle is hollow structure, and spray nozzle front end is equipped with buckle press joint,
Buckle press joint is arranged in the hollow hole of nozzle, and buckle press joint front end is equipped with front end sebific duct, and buckle press joint is also hollow structure, preceding
Sebific duct, buckle press joint connection nozzle are held, the micro- vehicle of spray nozzle front end is equipped with rubber tube and taper washer successively, and taper washer passes through spiral shell
Bolt is fixed on spray nozzle front end, and end section is big after the taper washer front elevational sectional is small, on the nozzle in the rubber tube
Equipped with horizontal longitudinal hole, B slurries are by side runner in sebific duct flow nozzle in work progress, under pressure by laterally vertical
Taper washer is flowed to along gap between nozzle and rubber tube to through hole, and is sprayed outward along the taper washer conical surface, tapered pad
The effect of scattered B slurries is enclosed, is sufficiently mixed A, B liquid, slurries is avoided along the outflow of same fixed-direction slurries to be caused to mix
It is uneven.
Above-mentioned buckle press joint and nozzle junction is threadedly coupled for seal pipe.
Above-mentioned at least two mutually perpendicular through hole of horizontal longitudinal hole.
The front end of above-mentioned nozzle and the aperture of the hollow structure of buckle press joint cooperation are more than the hole of the hollow structure of rear end
Footpath, buckle press joint, the aperture of sebific duct are identical with the aperture of nozzle rear end, and B liquid injection process will not generate pressure differential.
The outer diameter of above-mentioned spray nozzle front end is more than the outer diameter of rear end, it includes leading portion, transition and back segment from front to back.
Beneficial effects of the present invention：
1st, the nozzle is mounted on A slurries exit, and structure can be such that B liquid grouts uniformly spray, and A, B liquid are uniform during making slip casting
The quick solidification of mixing, shield tail B liquid grouts nozzle are uniformly flowed out in port of export taper washer side by the nozzle of special processing,
B slurries can be made to disperse to spray, so that A, B liquid are sufficiently mixed；
2nd, it is threadedly coupled by buckle press joint and nozzle junction for seal pipe, convenient disassembly, sebific duct can be indefinite over long distances
Direction is set.
3rd, horizontal at least two mutually perpendicular through hole of longitudinal hole can greatly improve hydrojet into tapered pad
Nozzle surrounding can be dispersed in before circle.
4th, the front end of nozzle and the aperture of the hollow structure of buckle press joint cooperation are more than the aperture of the hollow structure of rear end, button
Crimp head, the aperture of sebific duct are identical with the aperture of nozzle rear end, and B liquid injection process will not generate pressure differential.
5th, the outer diameter of spray nozzle front end is more than the outer diameter of rear end, it, which includes leading portion, transition and back segment, from front to back to protect
The substantially constant outer diameter of whole device is held, is transported convenient for preserving.
Description of the drawings
It is illustrated below in conjunction with attached drawing with embodiment
