Continuous paving construction technology of cement concrete bridge floor and steel bridge floor

Abstract

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.

Description

technical field [0001] The invention relates to a continuous paving construction technology for a cement concrete bridge deck and a steel bridge deck in the technical field of construction engineering. Background technique [0002] At present, with the rapid development of my country's economy, the construction of highways and bridges in my country has also developed rapidly, and there are various types of bridges. my country's bridges are mainly cement concrete bridges, steel bridges, cement concrete bridges and steel bridge composite bridges. In our country, the paving technology of bridge deck asphalt concrete surface has been mature. However, when the composite bridge of cement concrete bridge and steel bridge is encountered in surface course construction, because the cement concrete bridge and steel bridge use different asphalt mixtures, the paving of the bridge deck cannot be continuous but still be carried out in sections. That is, after the paving operation of one ...

Problems solved by technology

This form leads to: first, the paver cannot move continuously, and the paving operation cannot be carried out continuously; second, the paver screed is lifted off too many times, and the amount of manual paving increases; Before that, the electronic sensor would be turned off first, resulting in the inaccurate control of the road surface elevation at the joint; Fourth, after the paver screed is lifted, the remaining materials must be manually paved and processed, resulting in uneven road joints, which increases the difficulty of follow-up work. Affect the flatness of the road surface; Fifth, when paving another asphalt mixture, the equipment is frequently transferred, and the new road surface is frequently rolled, which reduces the service life of the road surface
