The tail grout stop system is primarily composed of grout stop plates, pressing plates, and bolts. The auxiliary sealing system works in conjunction with the tail sealing brushes to form a complete tail sealing system.
Typically installed behind the sealing brushes, its main function is to prevent the synchronous grouting slurry from flowing forward, and to work with the sealing brushes to maintain pressure balance in the tail sealing chamber.
It must be used in combination with the sealing brushes in all types of strata, and its grout-stopping function is especially critical under conditions of high grouting pressure and high slurry fluidity.
