Description

Technical Field

[0001] The embodiment of the utility model relates to the technical field of bridge operation, and in particular to a bridge deck concrete construction platform. Background Art

[0002] At present, bridge deck concrete paving is a key process in bridge operations. Controlling the three degrees of bridge deck concrete paving, thickness, strength, and flatness, is the key to the operation. When pouring concrete on the bridge deck, the concrete surface needs to be slurried, leveled, smoothed, and cured, so as to make the concrete densely combined and eliminate the honeycombed surface of the concrete, so as to improve its strength and ensure the quality of concrete components.

[0003] There are mature construction techniques and methods for bridge deck concrete paving. However, after the concrete for bridge deck paving is poured, the common vibration and finishing construction of bridge deck concrete is basically carried out manually using machinery in steps. Because the concrete has not reached final setting, the workers need to walk on the top surface of the poured concrete, which will leave marks on the concrete surface, thus having a great impact on the flatness and appearance quality of the bridge deck. The above-mentioned processes are all carried out in steps, which requires a lot of manpower and material resources, and the construction process is relatively long, which also has a great impact on the progress of the project.
