Abstract

The invention is suitable for the technical field of reinforced concrete box girder construction, and provides a tensioning tunnel direction measuring system. The system includes: a running device for running on the inner wall of the tension tunnel; the running control device, connected with the running device, for pulling the running device to run; the measuring device, installed on the running device On the device, it is used to measure the running parameters of the running device in real time when the running device is running in the tension tunnel, and the running parameters include acceleration data and angle data. According to the operating parameters, a model of the direction of the tension tunnel is established, and the actual rotation angle of the tunnel can be measured to avoid the problem of inaccurate tension force caused by the calculation of the rotation angle according to the drawing.

Description

technical field [0001] The invention belongs to the technical field of reinforced concrete box girder construction, and in particular relates to a tensioning tunnel direction measuring system. Background technique [0002] Prestressed reinforced concrete box girder is a kind of beam commonly used in high-speed railway. The longitudinal prestressed steel strand passes through the longitudinal steel bundle channel formed by the single-wall plastic bellows embedded in the construction, and performs tensioning, anchoring and grouting, etc. process to complete the box girder construction process. The tension value, elongation and other parameters of the steel strand are one of the main control items that affect the quality of the box girder. The determination of these parameters is closely related to the anchor loss of the box girder and the friction loss of the tunnel. In the loss test, the rotation angle of the channel is an important parameter, so the angle of the channel nee...
