[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0019] This application provides a prefabricated steel structure cofferdam, mainly used to solve the problem that when disassembling and assembling the dock gate hinge seat of the gate of the dock cofferdam, it is often necessary to block the water inlet of the dock cofferdam first before maintenance. Currently, there are various water-blocking methods, generally temporarily building with earth and stones, and it cannot be reused, which is rather wasteful of resources. And the following technical solutions are provided. The following will be combined with Figures 1 - 4Make a detailed description:

[0020] An assembled steel structure cofferdam, comprising: a dock body 1 with several water retaining plates 2 slidably inserted into its inner wall; several dock door hinges 3 fixedly installed on the inner wall of the dock body 1; and connection rings 4 fixedly installed on the tops of several water retaining plates 2. The user can connect one end of the steel wire rope of a stretching machine to the surface of the connection ring 4 and move several water retaining plates 2 through the stretching machine. It also includes a limiting mechanism 5, which is used to install several water retaining plates 2 on the inner wall of the water inlet of the dock body respectively. The main components of the dock body 1 are: a dock bottom plate 101 and a dock door pit 102.

Several dock door hinges 3 are fixedly installed on the surface of the flat surface 105. The dock door hinges 3 are used to install the gate on the surface of the flat surface 105. At the same time, the user can limit the water retaining plate 2 arranged on the inclined surface 103 through the limiting mechanism 5. The main components of several water retaining plates 2 are: several main plates 201. At the same time, several inclined rods 202 are rotatably installed on the surfaces of several main plates 201. Several main plates 201 are arranged on the inclined surface 103.
