Angle α 5 ° -45 ° of scope.The thick liquid discharge mouth of existing grout sleeve is parallel and vertical with sleeve body axis with grouting mouth, this
The grout sleeve thick liquid discharge mouth of invention is inclined upwardly and discharge pipe is also inclined upwardly, when grouting intracavitary grouting material is because shrinking, being vented, leaking
When the reasons such as slurry flow back under gravity, the grouting material in discharge pipe smooth can also flow back, and be unlikely to form blocking.In order to
Grouting material is smoothly flowed back, the inclined angle of discharge pipe axis should be greater than 2 degree, consider discharge pipe installation deviation, thick liquid discharge mouth to
Inclination angle should be not less than 5 degree, while unsuitable long in view of discharge pipe, and the angle of inclination of thick liquid discharge mouth is not also preferably greater than 45
Degree.
Further, angle of inclination is preferably：The α is 10 °.
The molding mode of sleeve thick liquid discharge mouth can have it is a variety of, optimum processing mode be casting when, the thick liquid discharge mouth with
Sleeve body is processed and formed at one time.
It is inclined upwardly to form thick liquid discharge mouth, also can individually processes a plasma discharge joint, the thick liquid discharge mouth is independent by one
The plasma discharge joint of processing is rigidly attached in the sleeve body of perforate and is formed as an entirety.The plasma discharge joint and sleeve sheet
The connection method of body is welding, threaded connection or grafting, can also be that other are fixedly connected with mode.
The beneficial effects of the utility model are the grout sleeves of the present utility model for being easy to check Grouted density, grouting
Sleeve thick liquid discharge mouth is inclined upwardly and discharge pipe is also inclined upwardly, when grouting intracavitary grouting material because shrinking, being vented, the reason such as spillage exists
When being flowed back under Action of Gravity Field, the grouting material in discharge pipe smooth can also flow back, and be unlikely to form blocking, so produce three aspects
Effect：
(1) the grouting material backflow in discharge pipe serves the effect of feeding, improves Grouted density；
(2) the smooth backflow of slurry in discharge pipe, make caused by the reasons such as the slurry contraction of grout filling region, exhaust, spillage
Cavity is transferred to the top in grout filling region, and grouting material apical position can be easily watched by thick liquid discharge mouth, so as to judge
The compactness of grouting；
(3) when grout filling region top cavity is excessive, it is necessary to when repairing, grouting material simply can be injected from thick liquid discharge mouth
.
The discharge pipe of existing grout sleeve installation is horizontal, it is also possible to is tilted down, when tilting down, in sleeve
The grouting material of the discharge pipe mouth of pipe can not flow back when grouting material flows back, and block the mouth of pipe, it is impossible to by checking being full of for mouth of pipe grouting material
Whether situation judges to be in the milk in sleeve closely knit., also will not be smooth time due to the viscosity of grouting material even if discharge pipe is horizontal
Stream.Therefore above-mentioned effect that no the utility model grout sleeve possesses.
