The BIM-based immersed tube construction system includes a floating information acquisition unit, an installation information acquisition unit, a floating data storage unit, and an installation data storage unit, etc.; it also includes a BIM model for establishing an immersed tube floating transportation based on the data of floating transportation and shipping conditions. The first modeling unit is used to establish the second modeling unit of the immersed tube installation BIM model according to the immersed tube installation environment, and the first modeling unit further dynamically updates the immersed tube floating transport BIM model according to the obtained immersed tube floating transport data, The second modeling unit further dynamically updates the immersed tube installation BIM model according to the acquired real-time installation data of the immersed tube. The system and method use BIM to establish the overall model of the entire project, which can visually simulate the process of floating and installing immersed tubes, and use the measurement and control system to collect floating and construction data to achieve dynamic visualization of the entire construction process Monitoring and recording and visual forecasting to complete the overall coordination and guidance of the floating and installation process of immersed tubes.
Description
technical field [0001] The invention relates to the technical field of immersed tube tunnel construction, in particular to a BIM-based immersed tube construction method. Background technique [0002] The immersed tube method is the main method for constructing underwater tunnels. The construction of the immersed tube mainly includes two steps: the floating of the immersed tube and the sinking installation of the immersed tube. It is necessary to transport the immersed tube to the designated location, sink it in the pre-dug foundation trench, carry out hydraulic pressure bonding for underwater connection, and then cover with soil and backfill. [0003] The floating process of immersed tubes is affected by natural conditions, channel conditions and floating ships. For example, different natural conditions, water flow speeds, and water flow directions will directly affect the floating course of immersed tubes. In order to achieve precise construction, the sinking index of eac...
