Improvement method and improved structure of decontaminating scraper pan rail

Abstract

The invention discloses an improvement method and an improved structure of a decontaminating scraper pan rail. According to the improvement method and the improved structure disclosed by the invention, a combined rail is used for replacing an i-steel rail which is directly pre-embedded inside a trash rack pier in the prior art; in specific implementation, a bottom steel plate is pre-embedded inside a scraper pan groove of the trash rack pier in a pouring process of the trash rack pier; and then the bottom steel plate and the combined rail which is formed by welding profile steel are welded together. According to the improvement method disclosed by the invention, the profile steel is convenient to buy, simple to manufacture and machine and easy to control in precision and needs not to be manufactured in a factory; and the improvement method can effectively adapt to installation errors of the pre-embedded bottom steel plate, and improves the manufacturing efficiency and the installationefficiency of the decontaminating scraper pan rail.

Description

technical field [0001] The invention relates to an improved method and structure of a cleaning rake bucket track, and belongs to the technical field of metal structures of water conservancy and hydropower projects. Background technique [0002] At present, there are three types of cleaning methods for trash racks: manual cleaning, mechanical cleaning and grid cleaning. For mechanical cleaning methods, it is generally necessary to set up cleaning rake tracks. The prior art cleaning rake tracks Generally, the I-beam type is set in the second-stage concrete pier. This type of cleaning rake bucket track type has the disadvantages of slow concrete pouring speed in the second stage, and the difficulty in controlling the flatness and verticality of the second-stage concrete will cause the rake bucket of the cleaning machine to fail to enter. The groove needs to be chiseled out on site and the second-stage concrete is polished, which is labor-intensive and time-consuming, and the ec...

[0002] At present, there are three types of cleaning methods for trash racks: manual cleaning, mechanical cleaning and grid cleaning. For mechanical cleaning methods, it is generally necessary to set up cleaning rake tracks. The prior art cleaning rake tracks Generally, the I-beam type is set in the second-stage concrete pier. This type of cleaning rake bucket track type has the disadvantages of slow concrete pouring speed in the second stage, and the difficulty in controlling the flatness and verticality of the second-stage concrete will cause the rake bucket of the cleaning machine to fail to enter. The groove needs to be chiseled out on site and the second-phase concrete is polished, which is labor-intensive and time-consuming, and the economy is also poor, especially for the track of the cleaning rake bucket with a large height, so the existing technology is still not perfect
