Detector for prestressed pipeline

Abstract

The invention discloses a detector for a prestressed pipeline. The detector mainly comprises a pipeline probe car (1) provided with a camera. The camera is a camera device for shooting pictures in the pipeline, and the pipeline probe car (1) moves in the pipeline for shooting the pictures in the pipeline. The pipeline probe car (1) comprises a cylinder (11) and an end cap (12) for sealing an open end of the cylinder (11), a cylindrical structure with an open end and a cavity inside is formed, and a plurality of retractable car wheels (2) arranged in order are further disposed outside the cylinder (1). The retractable car wheels have moderate retractility, so car jamming doesn't happen even if bends exist inside the pipeline. Meanwhile, by the aid of the detector for the prestressed pipeline, deforming condition of ducts inside the pipeline can be discovered timely, and engineers can timely analyze and accurately judge the inside condition of the pipeline according to images returned from the inside high-pixel camera.

Description

technical field [0001] The invention relates to a pipeline detection device, in particular to a prestressed pipeline detector. Background technique [0002] Prestressed pipes are also called corrugated pipes. The compactness of the grouting has an important impact on the durability of the bridge. According to statistics, due to the incomplete grouting, the steel strands in the prestressed pipes are corroded, and the prestress is lost in advance, which can cause the bridge The actual life is shortened to one tenth of the design life. There are currently approximately 570,000 highway bridges in the United States, of which approximately 130,000 are defective. The average age at which problems begin is 25 years. In my country, as of 2002, there are about 280,000 bridges of various kinds, among which there are about 9,597 dangerous bridges, and their average age of starting problems is 7 years. [0003] Prestressed pipeline construction is an important part of simply suppo...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the defect that there is no corresponding detection instrument that can detect the leakage of prestressed channel and the position deviation of prestressed reserved channel in time during the construction process of prestressed pipeline, and provide a simple result, It is a prestressed pipeline detector that is easy to use and can timely and effectively feedback the leakage of prestressed channel and the position deviation of prestressed reserved channel.
