Document Type and Number:
WIPO Patent Application WO/2022/073485
Kind Code:
A1
Abstract:
The present application provides a cofferdam locking mechanism, comprising a female lock assembly and a male lock assembly. The female lock assembly is detachably connected to the male lock assembly and comprises a female lock connecting rod; one end of the female lock connecting rod is connected to a connector A and the other end is connected to a "C"-shaped connecting portion; the male lock assembly comprises a male lock connecting rod, one end of the male lock connecting rod is connected to a connector B and the other end is provided with an elliptical connecting block, and the elliptical connecting block is detachably arranged in the "C"-shaped connecting portion. The gap between the female lock and the male lock is small, and the elliptical shape is not prone to relative rotation in a fitting state; the present invention thus will not cause relative offsets, has strong tensile property, is uneasy to be unhooked, guarantees the overall construction straightness and construction quality, requires few materials when filling is performed in the later stage, saves material costs, also ensures the effects of water and sand stop, and has a higher degree of integration and stronger weighing capacity.
