Automatic grouting system
Technical field
The present invention relates to solution cavity slurry injection technique.
Background technology
Metro shield originate, receive, tunneling and the work progress such as tunnel, coal mine excavation in due to complex geologic conditions
Or construction experience deficiency occurs often situations such as causing water burst, gush sand, in order to ensure the steadiness on ground, fill due to gushing
Water, gush underground space caused by sand in (such as solution cavity), it is to avoid water burst, the risk for gushing sand occur again, it is therefore desirable to take corresponding
Treatment measures, in order to reach the effect of rapid leak stopping well, fill formation void, using the single, double slurries (water of injection
Mud-waterglass) method alternately reinforced blocked.
And at present in terms of the making of slurries, artificial slurrying being fully relied on, personnel demand amount first is big, secondly metering aspect
It is not easy to ensure accurate, again, repulping rate is slower, it is difficult to meet slip casting demand, finally, Manual material feeding easily causes something lost
Spread, pollute environment.
Slip casting aspect, only with slush pump each individually slip casting, every machine must always have monitoring personnel in monitoring, people
Member's aspect is relatively more, and only manometric pressure value is monitored to slip casting situation, and monitoring is not comprehensively, not in place, and grasps
Fully rely on manually, operation has certain time delay.
