Introduction to the Quality Control of Communication Tower Installation
The communication tower installation should meet the following conditions:
(1) The communication tower design documents have passed the review;
(2) The foundation of the communication tower has been checked and accepted;
(3) The communication tower has complete components and pre-assembly records;
(4) The communication tower installation and construction equipment is complete, and the engineering and technical personnel and on-site operators are in place;
(5) Before the installation of the communication tower, the supervisor should review and approve the construction organization design or construction plan and safety measures of the contractor. The plan that does not meet the requirements shall be ordered to be re-edited or revised.
The installation of the communication tower must ensure the stability of the structure and prevent permanent deformation.
Before installation, the components of the communication tower should be checked according to the component list and the installation arrangement diagram, and the quality certificate and design modification documents should be checked. And according to the pre-assembly qualification record, it is strictly prohibited to reluctantly assemble. ⒋Check whether the size of the iron tower root opening is equal to that of the foundation root opening.
During the installation of the communication tower, the verticality should be verified at any time. The deviation between the actual axis of the erected communication tower and the designed axis is not more than 1/1500 of the height of the tower, and the local bending is not more than 1/750 of the measured length.
Supervisors must perform intermittent inspections on the installation of the tower in accordance with the design documents of the communication tower, and supervise the construction unit to ensure that the installation techniques, verticality of the tower body and the inclination of the central axis of the tower meet the requirements of the engineering design and related specifications for the installation of the tower.
