Flowing form observation device and method for concrete pumping in arch bridge pipe

Abstract

The invention discloses a flowing form observation device and method for the concrete pumping in an arch bridge pipe. The device comprises an arch rib, a camera device, a video acquisition instrument,a power supply and an annular waterproof lamp strip; the arch rib is formed by butting a plurality of sections of steel pipes through flange plates; the flange plates are connected through bolts andare provided with lining pipes; a camera device is mounted at the top of the steel pipe inner side wall; the camera device comprises a camera, the camera right faces the flange plate connecting position of the steel pipe, the waterproof lamp strip is arranged around the flange plate lining pipe on the inner side of the arch rib, the video acquisition instrument is installed outside the arch rib, the camera device and the video acquisition instrument are connected with the power source through electric leads respectively, and the camera device is connected with the video acquisition instrumentthrough a signal line. The technical problem that observation of the flowing form of concrete in a pipe, especially the flowing form at the flange plate, is difficult can be solved.

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 ...
