The project provides for the placement on the allotted land plots - capital construction facilities - of a digital radio and television station (RTS). The facility provides for the installation of a tower H=50m and a feeder bridge from the designed tower to the existing building.

Tower H=50,0m

The design of the tower is conventionally designed in two parts. The lower part is a pyramidal part from the base of the tower to the mark +42,0m with dimensions in plan: 6,52m (at the base) and 2,18m (mark +42,0m). The upper part is a prismatic part from the mark +42,0m to the mark +50,0m with dimensions in plan of 2,18m. At the level of +50,0 m, a technological platform is provided for the placement and maintenance of antenna-feeder devices. The platform is an octagon in plan. Pipe racks 0114mm 1,1 m high are provided in the corners of the site fencing. In the center of the technological platform, at elevations of +50,0m, a bearing pipe rack 0377mm with a wall thickness of 24mm is designed from two parts connected on flanges. At the level of +62,0m, a technological site was designed with dimensions in terms of 1,4m x 1,4m. In the center of this platform, a pipe rack 0210 mm 1,5 m high is provided. Belts and all load-bearing elements of the turret shaft (braces, struts and diaphragms) are made of angular equal-shelf steel and bolted together. To mate the lower section of the tower with the foundation, support shoes are provided. The sections are connected to each other on flanges using bolts. Inside the tower shaft there is a ladder-ladder and two cable-growths. Transitional and operational platforms are provided for equipment maintenance and recreation at elevations of +4,5m; +10,5m; +16,5m; +22,5m; +28,5m; +34,5m; +40,5m; +47,1m. The 50m high tower accommodates the equipment specified in Annex 1. The bearing capacity of the tower ensures the installation of antenna-feeder equipment in the future, 30% of the equipment specified in Annex 1.

feeder bridge

The feeder bridge is designed to pass the cable path from the H=50m tower to the control room located in the existing building. In cross section, the feeder bridge has the following dimensions: height - 0,6 m, width - 1,0 m. The feeder bridge is designed for laying the designed feeder route. The feeder bridge is covered with a steel mesh from above. The feeder bridge rests on metal supports. The bridge supports are designed with a height of 2,0 to 2,7 m, installed in increments of no more than 3 m. The support legs of the feeder bridge are made of a profile pipe, the feeder bridge is made of a channel, angle equal-shelf steel and flat steel, all connections are made by welding. The bearing capacity of the feeder bridge provides in the future the installation of cables 30% of the existing ones specified in Appendix 1. To ensure the service life of the anti-corrosion coating for at least 3 years, prime all metal structures with Epiprime 0-46 type coating and paint with Temadur 50 coating for 3 times . It is necessary to install a 2m long cable tray in an existing technological building for laying the project. feeders from noun. Equipment before the project. feeder window. In accordance with RD 34.21.122-87, antenna-mast structures must be equipped with lightning protection devices throughout Russia, regardless of the number of hours of thunderstorm activity. Impulse resistance to current spreading of lightning protection grounding conductors should not exceed 10 Ohm. Lightning protection of elements mounted on metal supports should be carried out by electrically connecting them to the support elements at the place of their installation. The need for light protection of a tower located outside the area of ​​​​airfields is agreed with the relevant civil aviation departments. The light protection of the antenna support should be located on the site with elev. 62,000m and at elevation 28,500m and perform in accordance with the instructions of paragraph 3.3.16. + 3.3.33. REGA RF-94. Coloring should be done in alternating stripes of red (orange) and white, with the top and bottom sections painted red.
