Beschreibung
Zusammenfassung:	A boring and positioning system for constructing a winding underpass comprises a boring module, an intelligent total station module, a reflective surface mechanism (2), a communication and control module, a strapdown inertial navigation module (1.2), a dual-axis inclinometer module, and a boring positioning prism module. The communication and control module, the strapdown inertial navigation module (1.2), the dual-axis inclinometer module, and the positioning prism module are provided at the boring module. The intelligent total station module is provided behind the boring module. The reflective surface mechanism (2) is positioned between the boring module and the intelligent total station module. The positioning system employs an integrated positioning method to perform, in real time, precise calculation to obtain a six-degree-of-freedom orientation parameter of a boring machine in an underpass.
