The communication tower shall fill in the packing list. The box, the part's title, number and weight shall be indicated on the 3 boxes. In order to check the spot after the scene. Data quality is directly related to the main part of the quality of the project. The information is the root of the tower project.
The contractor must fill out the application form and the information will appear. The steel and other materials quality confirmation form and the experimental report are submitted to the supervision unit. The on-site data will be counted together with the establishment unit and the contracting unit, and the supervision unit will receive the inspection form. Reflecting on the size, variety, number, specification and galvanized thickness of the iron tower components, whether it meets the design requirements and reflects the method of self-test, self-test and sampling according to the relevant national rules, the consequences must conform to the national norms.
1. Mobile communication tower data control
2. The electrode must be E43 quality must comply with the rules of GB5118-85, the quality of the flux must conform to the rules of GB1308-85; the prestige agency should confirm and verify the application and declare the application; 2 if new information is adopted.
3. The number, component, and quality of components must meet the design requirements.
4. Regarding the components and steel materials, samples should be sent for inspection.
Steel must have a quality certificate, and the quality of the steel must conform to the rules of GB700-88GB1591-94 and YB168-70. And meet the requirements of the design documents, if the supervision unit has doubts about the material, it must be sampled according to the relevant national standards, and the consequences can be used in accordance with the national norms and design documents.
If there is deformation, the size and specifications of the 5 components must meet the design requirements. Correction is necessary and the component must not be cold corrected when the temperature is below -16 °C. If there are delamination or crack defects at the fracture, the depth of the rust, pitting or scratch of the 6 steel material shall not be greater than half of the negative deflection value of the steel thickness. The supervision unit will discuss and dispose of it with the relevant unit. The data and function quality of the wire rope and steel strand (pull wire) used for the 7 pull tower of the communication tower must meet the relevant national rules and design documents.
