During the inspection and completion acceptance, the construction unit shall be responsible for the maintenance and appraisal if any work content that does not meet the requirements of this specification or relevant regulations is found.
Extended data:
The construction of communication pipelines and channels shall comply with the relevant national standards and specifications in addition to the implementation of this specification.
Equipment inspection The specifications, procedures and quality of the equipment used in communication pipeline engineering shall meet the requirements of design documents and technical specifications, and the construction unit or supervision unit shall organize the site inspection before use. Found defective or unqualified equipment should be handled in time. ?
Any equipment with factory certificate shall be inspected after quality and technical appraisal. Any equipment without factory certificate shall not be used in this project. It is forbidden to use unqualified equipment.
The equipment under test should be checked. Communication plastic pipeline equipment comes into the site, and its storage, custody, fire protection and safety meet relevant standards. The varieties and labels of cement and cement products used in communication pipeline engineering should meet the design requirements;
Pay attention to the date of cement production or certificate before use, and it is strictly prohibited to use it in projects without product certificate or logo; Expired cement shall not be used, and wet and deteriorated cement is strictly prohibited.
Various grades of cement should meet the product quality standards stipulated by the state. Cement leaving the factory for more than three months or showing signs of deterioration should be inspected and used before use. Determine whether to use or replace according to the identification. Communication pipeline engineering, the cement label used may be;
The cement type can be ordinary portland cement, slag portland cement or pozzolanic portland cement. Cement should be moisture-proof during storage, and should be purchased in batches according to the purchase date and stacked separately to avoid pressure when it is used for the first time.
