The main components to determine the geometrical position of the communication tower (tower hanger, cross bar, rigid inclined bar, etc.) should be installed on the design position of the communication tower, and it should be initially corrected and fixed before the hook is released.
After lifting a layer of communication tower components, it must be calibrated according to regulations. At this time, the supervisors should focus on the side stations and conduct parallel spot checks.

When continuing to install the communication tower of the previous layer, the deviation value of the next layer should be considered.

The installed communication tower structural unit should take into account the natural deformation of external environmental influences (such as wind, temperature difference, and sunlight) when detecting and adjusting.
The communication tower adopts flange-connected nodes. The fitting rate of the flange contact surface is not less than 75%. Check with a 0.3mm feeler. The sum of the area of the insertion depth must not be greater than 25% of the total area. mm. When it is exceeded, the gasket should be solidified. The gasket should be galvanized and treated with anti-corrosion.
The nodes of the communication tower are connected by node boards. The contact rate of the two planes in contact is not less than 75%. Check with a 0.3mm feeler. The sum of the areas of the insertion depth must not be greater than 25% of the node area.
The antenna support (holding pole), hanging height, and orientation should meet the design requirements of the communication tower, and it should be firmly connected with the structural components of the steel tower.
The position and strength of the feeder crossing the bridge should meet the design requirements of the communication tower, and it should be firmly connected to the structural components of the steel tower. The feeder must pass through the bridge with a certain inclination. The end of the feeder window should be slightly higher than the end of the tower, with an inclination of about 0.5% to 1%.
Communication tower with tower, water, electricity, heating pipeline location, strength, etc. meet the design requirements of the communication tower and should be firmly connected to the steel tower components.
The steps of the communication tower stairs should be flat and the inclination error ≤ ± 2.0mm. The railings between the upper and lower sections of the straight climbing ladder and the vertical bars of the platform guard ring should be connected into one body, and all the railings should be firmly connected with adjacent boards.
After the communication tower is installed, the overall verticality and height must be measured and corrected. All data must meet the requirements of the specification. The bolts exposed on the top surface of the foundation should be coated with anticorrosive materials (such as butter) to prevent rust and damage.
