Erecting sealing wall with strip-shaped sealing element clamped to rigid, frame-shaped support - using winding drum for sealing element sinking, which exerts controllable resetting force onto sealing element sinking into ground slot.

摘要

Together with the support (10), the sealing element (2) is lowered into a vertical ground slot (3). During lowering, the sealing element is rolled-off a drum (1) and secured to the frame of the support. Pref. the element is lowered by the support weight. The drum exerts a controllable resetting force onto the sealing element to be lowered into the ground slot. For the element lowering, a controllable force, opposing the resetting force and overcoming the resistance of filling material in the slot, is exerted onto the sealing element. USE/ADVANTAGE - Improved erection and film clamping for sealing wall.
