The communication tower tower body can be installed in a single piece, expanded assembling and comprehensive installation. If necessary, it can also be installed by the method of integrally lifting the communication tower.

When the communication tower is expanded and assembled (single rod members are spliced into assembly for installation), the supervisory personnel shall request the contractor of the communication tower to perform strength and stability check on the components that are easily deformed, and reinforcement measures shall be taken when necessary.

When the communication tower is integratedly installed, the supervisor should check whether the independent units divided by the contractor of the communication tower are reasonable. After all the components of the communication tower of each system (unit) are installed, they have sufficient lifting space, strength and reliable stability. .
When the communication tower is installed with a whole board, when the contractor is installing it, the supervisor should review whether the design unit agrees to the recalculation and whether the design unit has a complete calculation of the communication tower auxiliary facilities and equipment.
The installation position of the communication tower tower shoes should meet the design requirements of the construction drawing. The communication tower tower shoes and the top surface of the foundation should be closely fitted with a gap of ≤ 3mm, but the area should not exceed 25% of the bottom of the communication tower tower shoes. The deviation between the center axis of the bolt hole of the shoe bolt and the top surface of the foundation bolt is ≤1.5mm, the center distance of each tower shoe should be equal, and the allowable deviation is ≤2.5mm. 1.5mm. After adjusting the level of each communication tower tower shoe, temporary reinforcement measures should be taken to make it bear the load of one or several structural units. After the first structural unit is installed, the theodolite is used to check the accuracy and verticality of the structural installation. After the requirements are met, the steel structure is used for permanent support or the cement mortar is filled under the tower shoe steel plate.

When it is necessary to use the installed structure to hoist other communication tower components and equipment, the consent of the design unit shall be obtained, and the strength and stability of relevant components shall be checked. Reliable measures shall be taken to prevent damage to the communication tower structure.
The main communication tower components (tower hanger, cross bar, rigid oblique bar, etc.) to determine the geometric position should be installed on the design position, and it should be initially corrected and fixed before releasing the hook.
