Abstract

The invention discloses a real-time measurement system for shield tunneling posture, comprising a total station instrument which is arranged behind a shield machine and is provided with an automatic target recognition function and a plurality of target prisms fixed in the shield machine, wherein, the target prisms are arranged one by one along the longitudinal direction of the shield machine; the system also comprises a double-axis tilt sensor, and the double-axis tilt sensor is arranged on a special mounting base fixed in the shield machine. The system eliminates the contradiction between the improvement of the measurement accuracy and the extension of the continuable observation distance, particularly can adapt to the working environment with worse intervisibility conditions, has the advantages of high measurement accuracy and simple and convenient installation, can adapt to the shield tunneling construction with various conditions, and particularly adapt to the tunnel construction of small diameters and small curvature radii.

Description

Technical field: [0001] The invention relates to a control device for shield tunneling, in particular to a real-time measurement system for shield tunneling attitude. Background technique: [0002] Shield tunneling technology is an engineering technology for underground tunnel excavation, and determining the real-time posture of the shield machine during tunneling construction is one of the keys to this engineering technology. The shield tunneling posture real-time measurement system is used in shield tunneling construction The control device used to detect the real-time posture of the shield machine. The shield tunneling posture real-time measurement system uses advanced measurement, sensing and computer technologies to detect the position, posture and trend information of the shield machine in real time, and compare it with the designed tunnel axis (Designed Tunnel Alignment, hereinafter referred to as DTA) at any time , providing real-time information to the operator of ...
