Abstract

The invention relates to a mid-span outer membrane concrete paving process, and belongs to the technical field of road and bridge construction. According to the mid-span outer film concrete paving process, a three-dimensional laser paving and leveling machine and a concrete surface finishing and film covering all-in-one machine are used; and a three-dimensional laser paving and leveling machine isused for vibrating and leveling a concrete pavement, and then a surface finishing and film covering all-in-one machine is used for troweling, surface finishing and film covering maintenance. The mid-span outer membrane concrete paving process can be applied to prefabricated beam top plate construction or bridge deck pavement paving construction, and integrated construction of large-span prefabricated beams can be achieved. The process is high in construction efficiency and good in construction quality.

Description

technical field [0001] The invention relates to a mid-span outer membrane concrete pavement process, which belongs to the technical field of road and bridge construction. Background technique [0002] The construction of concrete pavement needs to be clothed, leveled, troweled and covered in sequence. Traditionally, there is a corresponding construction machine for each process step. For example, the fabric needs to use a distributing machine, the leveling needs to use a leveling machine, the smoothing needs to use a trowel, and the film needs to use a laminating machine. Because the traditional machine is set up as a stand-alone structure, the machine needs to be replaced for each process, resulting in low process efficiency; and the traditional machine control accuracy is not high. [0003] In addition, in road and bridge construction, there is a way to manufacture prefabricated beams in a prefabricated beam factory, and then install them on site. The current machines a...
