Technical Field

[0001] The utility model relates to the technical field of river channel construction, in particular to a cofferdam protection reinforcement structure for river channel construction. Background Art

[0002] During river channel construction, a cofferdam is usually built in the construction area. In order to improve the stability of the cofferdam in the water, a protective reinforcement structure is usually set up for reinforcement. After searching, the Chinese patent authorization number CN206418511U discloses a reinforcement structure for a water conservancy construction cofferdam. The device uses side support bars movably installed at both ends of the supporting beams through connecting blocks, so that the supporting beams in the reinforcement structure of the cofferdam can effectively support multiple points at the same time, which can effectively reduce the demand for supporting beams and columns, and can effectively increase the construction space inside the cofferdam, while also achieving the purpose of reducing construction costs. However, when the cofferdam protective reinforcement structure is used in water with a fast water flow rate, due to the large resistance in the water, the stability is reduced under the impact of the water flow, resulting in the overall lack of firmness.
