Title:
BORING AND POSITIONING SYSTEM AND METHOD FOR CONSTRUCTING WINDING UNDERPASS
Document Type and Number:
WIPO Patent Application WO/2018/233390
Kind Code:
A1
Abstract:
A boring and positioning system for constructing a winding underpass comprises a boring module, an intelligent total station module, a reflective surface device, a communication and control module, a strapdown inertial navigation module (1.2), a dual-axis inclinometer module, and a boring machine positioning prism module. The communication and control module, the strapdown inertial navigation module (1.2), the dual-axis inclinometer module, and the boring machine positioning prism module are provided at the boring module. The intelligent total station module is provided behind the boring module. The reflective surface device is positioned between the boring module and the intelligent total station module. The above positioning system is applicable to both straight and winding underpasses. Also disclosed is a boring and positioning method for constructing a winding underpass. The method employs an integrated positioning method to perform, in real time, precise calculation to obtain a six-degrees-of-freedom orientation parameter of a boring machine in an underpass, thereby solving a problem of precise positioning and orienting of a boring machine in an underpass or tunnel.
