Shield tunnel universal segment dynamic virtual assembling system

Abstract

A tunnel shield universal segment dynamic 3D virtual assembling system applied in the tunnel technology field comprising a geometry modeling module for setting up the geometry model of the segments and the tunnel axis by parameter design and storing the model into a database, a universal segment selection module for obtaining the geometry model data from the database and processing them to obtain the segment point sequence of the tunnel axis and storing them into an assembling database, a core module namely the universal segment 3D virtual assembling and deviation detection module for extracting the virtual assembly required data from the assembling database interface, displaying the assembling process on the terminal and displaying the deviation between the virtual assembled segment center with the tunnel theoretical axis in the text and graph mode, a universal segment assembling data processing module for executing the data maintenance and communication with the database. The invention realizes the dynamic function of the universal segment in the tunnel shield construction to facilitate the on-time regulation of the tunnel machine posture.

Description

technical field [0001] The invention relates to a shield tunneling equipment in the technical field of tunnel engineering, in particular to a dynamic three-dimensional virtual assembly system for general segments of a shield tunnel. Background technique [0002] Because shield tunneling construction technology can minimize the impact on other facilities in the city, it has become the main form of urban tunnel construction in various countries around the world. Shield technology is also used in subway construction in Shanghai, Beijing, Guangzhou, Nanjing, Shenzhen and other places in my country. Segment assembly technology is an important part of shield construction technology. Different from ordinary segments, the lining ring composed of general segments has only one wedge-shaped structure. Through the orderly rotation and orderly combination of wedge-shaped rings, only one general segment can be used in the same tunnel. Industrial and mining conditions such as straight li...

AI Technical Summary

Problems solved by technology

These system software are all oriented to the construction process and integrated with the operating system of the shield machine. It is difficult to run independently, and it does not provide a visual 3D assembly display function, which is very inconvenient for construction process managers, monitors and evaluators.
