Abstract

The invention is suitable for the technical field of reinforced concrete box girder construction, and provides a tensioning duct trend measuring system. The system comprises: an operation device usedfor operating on the inner wall of a tensioning hole channel; the operation control device that is connected with the operation device and is used for pulling the operation device to operate; the measuring device that is installed on the running device and used for measuring running parameters of the running device in real time when the running device runs in the tensioning hole channel, and the running parameters comprise acceleration data and angle data. A tensioning duct trend model is established according to the operation parameters, the actual corner of the duct can be measured, and theproblem of inaccurate tensioning force caused by calculation according to the drawing corner is avoided.

Description

technical field [0001] The invention belongs to the technical field of reinforced concrete box girder construction, and in particular relates to a tension tunnel direction measurement system. Background technique [0002] Prestressed reinforced concrete box girder is a kind of beam commonly used in high-speed railways. The longitudinal prestressed steel strand passes through the longitudinal steel beam tunnel formed by the pre-buried single-wall plastic bellows during construction for tensioning, anchoring and grouting. process to complete the box girder construction process. The parameters such as tension value and elongation of the steel strand are one of the main control items affecting the quality of the box girder. The determination of these parameters is closely related to the anchorage loss and channel friction loss of the box girder. In the loss test, the channel rotation angle is an important parameter, so the channel angle needs to be obtained first when establish...
