When, slowly decline manipulation plate (2) and traction rope (1) allows undertaking by the thrust of limitation bucket (6) and the gravity of elastomeric isolation ball (7)
The water of lower section is gradually discharged by tray (8) with the hole on the gap of hole wall and tray (8) side wall disk (8)；
Step S106: when tray (8) reach area of isolation, manipulation plate (2) is promoted, stops the manipulation to traction rope (1), makes
Elastomeric isolation ball (7) is separated by self weight with limitation bucket (6), simultaneously because elastomeric isolation ball (7) internal insulation material (9) is to ball
The effect of wall, elastomeric isolation ball (7) are gradually completely attached to hole wall, plate (2) are manipulated by control, by end bar (3), connecting rod
(4), foot piece (5), limitation bucket (6) is held to propose outside hole.Continue to fill rendrock (10), sealing material (11), completes sealing of hole.
