Abstract

The invention discloses an observation device and method for observing the flow form of concrete pumping in an arch bridge tube, which includes an arch rib, a camera device, a video acquisition instrument, a power supply and a ring-shaped waterproof light belt. The flange is connected by bolts and is provided with a lining pipe. A camera device is installed on the top of the inner wall of the steel pipe. The camera device includes a camera. The camera is facing the flange connection of the steel pipe. The blue plate lining pipe is set, the video acquisition instrument is installed outside the arch rib, the camera device and the video acquisition instrument are respectively connected to the power supply through conductive wires, and the camera device and video acquisition instrument are connected through signal lines. It can solve the technical problem that the observation of the flow form of the concrete in the pipe is difficult, especially the observation of the flow form at the position of the flange.

Description

technical field [0001] The invention relates to the technical field of steel pipe concrete pouring equipment, in particular to an observation device and an observation method for the flow form of concrete pumped in an arch bridge tube. Background technique [0002] China's bridges are developing rapidly, and arch bridges have significant technical and economical properties under suitable conditions. At the same time, my country has entered the era of high-speed rail, and the advantages of concrete-filled steel tube arch bridges in terms of economy, rigidity, and durability are prominent. With the construction of the Sichuan-Tibet line, the demand for long-span concrete-filled steel tube arch bridges has increased dramatically. [0003] The economic value of concrete-filled steel tube arch bridges is very significant. In areas with suitable geology, the cost of bridges with the same span is half that of suspension bridges. In the past 20 years, China's CFST arch bridge has ...
