It was shown that the grouting pressure difference was related to the rheological parameters, consistency coefficient and gap width of grouting. The penetration radius was also affected by gap width.

Solenoid valve flow coefficient generally small, and the work of a very small pressure difference.

电磁阀一般流通系数很小，而且工作压力差很小。
