Description
Technical field
The utility model is related to grouting equipment field more particularly to a kind of underground coal mine slip casting components.
Background technology
Underground coal mine two fluid grouting is by coagulable slurries after two kinds of mixing, i.e. cement grout and waterglass slurries presses one
Fixed ratio is alternately injected in rock cranny, and two kinds of slurries, which react rapidly, generates gel, cementing and filling rock mass hole.
During underground coal mine two fluid grouting, the quality of cement grout and waterglass slurries hybrid reaction be slip casting success with
No key point.The optimal requirement of slip casting is to promote water-bearing layer or crack to lead to by the pressure of grouting pump after dual slurry mixes
Road, Seed harvest gradually deposit in crack, are finally reached the purpose of water blockoff and consolidating crack, and double liquid grout injecting mixer is just undertaken
The task of mixed serum.
The common two fluid grouting of underground coal mine is to mix two kinds of slurries before entering grouting pipe mostly at present,
Grouting pipe is injected after being sufficiently stirred and carries out slip casting operation, although this mixed method is uniformly mixed, arrives two fluid grouting
In the later stage, with the reduction of grout absorption, slurries flowing velocity slows down, and is solidified before not reaching crack also, therefore, it is difficult to protect
Demonstrate,prove the quality and effect of slip casting；And it is another using waterglass slurries and cement grout are injected, it is carried out inside slip casting duct
It mixes, this method uniformly mix two kinds of liquid, is unable to reach whole coagulation result；Also, with slip casting operation
Progress, cement grout can be remained in grouting pipe, grouting equipment line clogging can be caused without cleaning for a long time, influence work
Make efficiency.
