TBM concrete flatness control and concrete consumption statistics method

Abstract

The application discloses a kind of TBM concrete spraying flatness control and concrete consumption statistics method, the method includes the following steps: 1) laser grating reading device and signal warning light;2) install laser grating transmitting device;3) install point cloud scanning device;4) obtain excavation profile three-dimensional point cloud data, and process, obtain complete tunnel excavation topography point cloud model;5) complete scanning paragraph primary support construction;6) start point cloud scanning device, the three-dimensional point cloud data obtained is spliced and handled, and complete tunnel primary support topography point cloud model is obtained;7) the point cloud model data of processing completion is imported into primary support thickness analysis module, calculates tunnel primary support thickness and actual effective primary support concrete spraying amount, and compared with preset completed primary support design data, generates primary support flatness evaluation;The application can make the operator clearly understand the initial spraying thickness and the profile after primary support, effectively control the concrete spraying thickness, and improve the surface flatness.
