Structural safety appraisal of industrial parks.
With the rapid development of China's economy, the construction of industrial parks is increasing, and as an important part of industrial parks, the structural safety of factories has an important impact on industrial production and the normal operation of enterprises. Therefore, it is an important task to carry out a regular structural safety qualification of the plant.
1. Appraisal process.
1.Preparation.
Guangdong Fang 10Before starting the appraisal, the design drawings, construction records, use history and other relevant information of the plant should be collected in order to understand the basic situation of the plant. At the same time, it is necessary to determine the scope and purpose of the appraisal and formulate a detailed appraisal plan.
2.Site surveys.
The site investigation is the most important part of the identification process. The appraiser needs to conduct a detailed inspection of the appearance, foundation, load-bearing structure of the plant, and record the existing problems and damages. At the same time, specialized equipment should be used to carry out the necessary tests and obtain accurate data.
3.Data analysis.
Organize and analyze the data obtained from the on-site investigation, and evaluate the structural safety performance of the plant in combination with the design drawings and related standards.
4.Preparation of reports.
According to the results of on-site investigation and analysis, prepare a detailed appraisal report. The report should include the basic situation of the plant, existing problems, safety performance assessment and improvement suggestions.
5.Report review and acceptance.
After the appraisal report is completed, it needs to be reviewed and accepted by experts to ensure the accuracy and reliability of the report. At the same time, the appraisal report should be delivered to the entrusting party in a timely manner, so that it can take corresponding measures according to the report.
2. Identification content and methods.
1.Foundation identification.
The foundation is the foundation of plant safety. The appraiser should check whether the foundation has settlement, displacement and other phenomena, and evaluate the stability of the foundation. At the same time, the foundation material should be tested to ensure that it meets the design requirements.
2.Identification of load-bearing structures.
The load-bearing structure is the main support system of the plant. The appraiser needs to conduct a comprehensive inspection of the appearance, material, and connection method of the load-bearing structure to evaluate its bearing capacity and stability. At the same time, the key parts of the load-bearing structure should be tested to ensure that they meet the design requirements.
3.Identification of steel structures.
For the workshop with steel structure, the appraiser should inspect the material, size, and connection method of the steel components to evaluate the stability and durability of the steel structure. At the same time, non-destructive testing should be carried out on steel components to ensure that they are free of damage and defects.
4.Identification of concrete structures.
Concrete structure is a commonly used building material in factories. The appraiser should inspect the appearance, material, reinforcement, etc. of the concrete for a comprehensive inspection to evaluate the strength and durability of the concrete structure. At the same time, the bearing capacity of the concrete components should be tested to ensure that they meet the design requirements.
5.Identification of ancillary structures.
The plant also includes some ancillary structures, such as walls, roofs, etc. These structures should be examined by the appraiser to assess their safety. For problematic subordinate structures, reinforcement measures should be taken in time.
Through regular appraisal, the problems and hidden dangers of the plant can be found in time, the accidents and losses caused by structural safety problems can be avoided, the actual condition of the plant can be understood, and the basis for the enterprise to formulate maintenance and transformation plans. For factories with potential safety hazards, the identification results can provide a basis for ** and relevant departments, so that they can take corresponding supervision and rectification measures.
