As used herein, unless the context clearly indicates otherwise, the singular forms are also intended to include the plural forms. In addition, it should be understood that when the terms "include" and / or "comprise" are used in this specification, they indicate the presence of the features, steps, operations, devices, components and / or combinations thereof.

[0020] Such as Figures 1 - 6As shown in the figure, a curing device inside the compartment of a large caisson includes a curing combination unit 3 located inside the compartment 2 of the caisson 1. The curing combination unit 3 consists of a construction platform 4 and a spraying device 5 connected to the lower side of the construction platform. The construction platform is used to support the spraying device and provide a basis for construction operations. The spraying device 5 includes a spraying pipe 6, on which nozzles 7 are arranged at intervals. The diameter of the spraying pipe 6 is 2.5 cm, and 180° nozzles are used. By building the construction platform and the spraying device, precise control and convenient management can be achieved, and comprehensive spraying curing of the inside of the caisson compartment can be realized, saving labor and material costs and improving the efficiency and quality of the curing operation.
