Continuous paving construction technology of cement concrete bridge floor and steel bridge floor
The invention relates to a continuous paving construction technology of a cement concrete bridge floor and a steel bridge floor, which is applied to the technical field of constructional engineering. The continuous paving construction technology of the cement concrete bridge floor and the steel bridge floor concretely comprises the following specific steps: carrying out preparatory work before construction, namely, preparing the bridge floors and carrying out bonding oil construction, wherein the bridge floors are cleaned until no loose stone, dust and impurities exist before asphalt mixtures are paved, and an asphalt disperser is used for spraying the bonding oil, so that the paving operation can be implemented continuously; carrying out construction layout and height resurvey, namely, carrying out comprehensive resurvey on the indexes such as lengths, widths, heights, cross slopes and flatness of the bridge floors by survey crew at the early period; detecting the flatness of the bridge floors by a vehicle laser pavement roughness detector, and recording the results; staking out in survey. According to the technology, the whole paving process is continuous, and the demands on paving works of different types of asphalt mixtures of the cement concrete bridge floor and the steel bridge floor can be met at the same time; after the technology is adopted, the problem of uneven pavement caused by the sectional operation in the paving process can be avoided, and the engineering cost is lowered.
