Description

Technical Field

[0001] The utility model relates to the technical field of cable support and fixation, and in particular to a cable fixing structure for a bridge sound barrier. Background Art

[0002] In recent years, with the development of society and the economy, people's demand for mobile communications has become increasingly demanding. They desire to communicate and connect with anyone, anywhere, at any time. However, in enclosed or semi-enclosed spaces, the propagation of electromagnetic waves is significantly hindered, resulting in poor electromagnetic coverage and difficulty installing antennas in these locations. Leaky coaxial cable (LEC) can address these deficiencies, serving not only as an antenna but also as a transmission line. By manipulating the slots in the outer conductor, LEC can cover signal-blind areas. However, research on the installation of LEC within the noise barriers of railway viaducts is still lacking, and this research is urgently needed.

[0003] At present, leaky cables are mostly fixed by means of leaky cable clamps, hanging or support trays supported by building columns on buildings. However, research on the installation of leaky cables in the sound barriers of railway viaducts is still vacant. With the popularization of leaky cable installation, research in this area is imminent. Utility Model Content
