Technical Field

The present invention relates to an in-duct object conveying method.

Background

Various cables including optical cables, electric cables, cables and the like are often required to be laid along factories, large buildings, high-speed rail stations, subway stations, terminal buildings, high-speed rail lines and subway lines. To protect the cables and to provide an aesthetic appearance in the field, it is often necessary to lay these cables in conduits or bridges, or even to bury them in the ground. At present, the technology of laying optical cables in pre-buried special pipelines is mature, but cables are laid in bridges and threaded in some nonstandard closed narrow pipelines still adopt manual operation. Although the strength of the work is not high, the number of workers is large, the working efficiency is low, the construction period is long, and the construction cost is high. A more difficult project for the constructor is to supplement the threading and replace the cables in existing bridges or existing ducts that are used for a longer time, in which case the cables in the bridges and ducts hinder the threading work, which is usually done only by opening the bridges or digging out the ducts, which is more laborious. Therefore, in the field of cable laying construction, a method which can be used for efficient construction without excavating or opening a bridge cover plate is needed to be found so as to reduce the cost and solve the technical problem of threading and cable penetrating engineering.
