Intelligent tunnel construction measurement setting-out method based on BIM (Building Information Modeling)

Abstract

The invention discloses an intelligent tunnel construction measurement setting-out method based on BIM (Building Information Modeling). The method comprises the following steps: establishing a tunnelexcavation BIM model according to drawings, performing format conversion on the established BIM model, and copying to a BIM mobile station; after intelligent total station in-place operation is completed on a measurement setting-out site, connecting the BIM mobile station with an intelligent total station, setting measurement parameters through the BIM mobile station, and controlling the intelligent total station to complete connection and locking, and performing measurement setting-out by using an infrared non-prism; and after a testing station is set up, measuring any point on an excavationsurface, confirming a general distance of the excavation surface, automatically calculating the position of a setting-out point at the mileage by the BIM mobile station, and automatically searching anactual setting-out point at the cross part of the BIM model and the excavation surface front and back, thereby achieving automatic setting-out. By adopting the intelligent tunnel construction measurement setting-out method based on BIM, setting-out in the tunnel construction process can be accurately and conveniently implemented.

Description

technical field [0001] The invention relates to the technical field of building construction stakeout, in particular to a BIM (Building Information Modeling, Building Information Modeling)-based tunnel intelligent construction measurement stakeout method. Background technique [0002] Tunnel excavation measurement stakeout is different from other structure stakeouts. It uses interval points to draw the position of the surrounding blasthole line on the excavation section. Because the actual excavation section of the tunnel is not a flat plane, the excavation section and stakeout points The mileage is not on the same mileage, so the stakeout point cannot be calculated in advance, and the actual stakeout point needs to be found before and after the mileage after calculation based on the calculated point. [0003] In traditional stakeout, one can only roughly estimate an excavation mileage according to the excavation section, and calculate according to the estimated mileage. Aft...
