Water use of bottom hole circulation grouting plug is widely used in hydropower station, reservoir engineering curtain, consolidation, backfill, chemical grouting, geological exploration water pressure testing and water shutoff in drilling. And it is also used in the hole pl ing and water shutoff of coal bed, gas testing and discharge. It can be used repeatedly for 30 - 50 times. Water use of bottom hole circulation grouting plug has three holes: the first one is used to inject water or air into it to make the rubber hose inflated, the second one is used to inject cement and the third one is used to discharge the water or gas produced in the cement injection process.

Application of water use of bottom hole circulation grouting plug:

• Water use of bottom hole circulation grouting plug is widely used in hydropower station, reservoir engineering curtain, consolidation, backfill, chemical grouting.
• It is used in geological exploration water pressure testing and water shutoff in drilling.
