Problems solved by technology

The existing trench cover plates are made of cement reinforced concrete and polymer composite materials, etc., but because they are exposed to the outside for a long time and are subjected to mechanical forces such as rolling, handling, and prying for a long time, they are very easy to be damaged, and the work is difficult. It is not easy to detect the damage of the trench cover in time because the personnel are regularly overhauled; in order to detect the damage of the trench cover, CN110095504A and CN111089716A disclose a trench cover that can be used to monitor the damage of the trench cover and open state

Abstract

The invention provides a method for pre-embedding a sensing line in a channel cover plate. The method comprises the following steps: taking a cover plate lower mold with a blind hole; placing a part of cover plate material on the cover plate lower mold, reserving the position of the blind hole, and flattening to form a first layer of cover plate matrix; placing the sensing line on the first layerof cover plate substrate, and plugging a sensing line connector into the blind hole; and paving the other part of the cover plate material to form a second layer of cover plate matrix, and paving thesecond layer of cover plate matrix on the first layer of cover plate matrix and the sensing lines. The sensing line pre-buried by the method has very high detection sensitivity.

Description

technical field [0001] The invention belongs to the technical field of pre-embedded sensing lines, in particular to a method for pre-embedding sensing lines in a trench cover plate. Background technique [0002] There are a large number of cable and optical cable trenches in power generation facilities. In order to ensure the safety of cables and optical cables in the trenches, avoid aging caused by direct sunlight, and prevent rain, dust, and debris from falling into the trenches, protection must be set up on the trenches. Functional trench cover. The existing trench cover plates are made of cement reinforced concrete and polymer composite materials, etc., but because they are exposed to the outside for a long time and are subjected to mechanical forces such as rolling, handling, and prying for a long time, they are very easy to be damaged, and the work is difficult. It is not easy to detect the damage of the trench cover in time because the personnel are regularly overhau...
