Document Type and Number:
WIPO Patent Application WO/2023/093632
Kind Code:
A1
Abstract:
The present utility model relates to the field of cofferdams, in particular to a lock-type steel pipe pile cofferdam for cemented pebble geology. The lock-type steel pipe pile cofferdam comprises a steel pipe pile structure. The steel pipe pile structure is internally provided with an inner supporting structure, and the steel pipe pile structure comprises a plurality of lock-type steel pipe piles, wherein the plurality of lock-type steel pipe piles are sequentially connected to enclose a rectangular frame structure; steel casings are provided inside the rectangular frame structure; and the steel casings are connected to auxiliary cofferdam supporting mechanisms. The present utility model discloses a lock-type steel pipe pile cofferdam for cemented pebble geology. In the present utility model, by means of the auxiliary cofferdam supporting mechanisms, the periphery of the cofferdam can be supported during secondary foundation cleaning for the cofferdam, and the cofferdam is prevented from relatively large deformation which is caused by surrounding pressure from a foundation pit during foundation cleaning and affects subsequent normal use.
