Description

Technical Field

[0001] The utility model relates to the technical field of cofferdams, in particular to an underwater earth and stone excavation auxiliary device. Background Art

[0002] As a temporary water-isolating structure, cofferdam plays a key role in underwater earthwork excavation. By building cofferdams, water and earth and rocks can be effectively blocked from invading the construction site, protecting the buildings under construction from damage and adverse effects. This can not only ensure the smooth progress of the project, but also improve the safety of construction.

[0003] The steel sheet pile cofferdam is formed by interlacing and connecting multiple steel sheet piles to form a cofferdam with a certain space in the water body, and the installed steel sheet piles are connected and supported by support beams to provide anti-dumping capability for the entire cofferdam. However, the support beams of traditional steel sheet pile cofferdams are usually prefabricated components of fixed length, which means that their length and span are determined during manufacturing and are difficult to flexibly adjust on site. Although this design method simplifies the production and installation process, it sacrifices its ability to adapt to steel sheet piles with different spacings. When the length of the support beam needs to be increased according to actual needs, it needs to be connected to one end of the support beam through a shorter support structure, which makes it inconvenient to adjust the length of the support beam. In addition, the connection between the support beam and the steel sheet pile is generally connected to the steel section by electric welding or bolts, which causes a large loss of the steel sheet piles and makes the disassembly and assembly of the support beam time-consuming and labor-intensive.
