Abstract

The invention provides an automatic sorting system and method for shield tunnel prefabricated box culvert piece splicing. The automatic sorting system is composed of a tunnel data acquisition module, a box culvert piece data acquisition module and a box culvert piece sorting industrial personal computer. The method specifically comprises the following steps that the tunnel data acquisition module acquires tunnel information and sends point cloud data to the box culvert piece sorting industrial personal computer; the box culvert piece data acquisition module acquires box culvert piece information and sends image data to the box culvert piece sorting industrial personal computer; and the box culvert piece sorting industrial personal computer processes the point cloud and the image data to respectively obtain the tunnel axis and the accurate size of the box culvert pieces, and then a splicing sequence of the box culvert pieces in the tunnel is obtained. The adjusting difficulty during splicing of the prefabricated box culvert pieces is effectively reduced, and the splicing quality of the prefabricated box culvert pieces is greatly improved; in addition, the relative positions of the prefabricated box culvert pieces can be provided, the installation device is guided to splice the prefabricated box culvert pieces, the splicing detection process is simplified, and the splicing efficiency of the prefabricated box culvert pieces is improved.

Description

technical field [0001] The invention relates to the field of splicing prefabricated box culverts of shield tunnels, in particular to an automatic sorting system and method for splicing prefabricated box culverts of shield tunnels. Background technique [0002] During the construction of the shield tunnel, the construction steps of the box culvert are relatively cumbersome. The traditional construction scheme adopts ordinary formwork for cast-in-place concrete construction, and the construction speed is slow. The new construction scheme uses prefabricated box culverts for on-site splicing construction, which significantly improves construction efficiency. When the box culverts are spliced, the box culverts need to be fine-tuned to meet the installation quality requirements of the box culverts. Due to the turning and settlement of the shield tunnel and the differences in the sizes of the prefabricated box culverts, the installation of prefabricated box culverts is increased. ...
