1. Overview.
Engineering explosion-proof wall is an important explosion-proof facility, which is widely used in petroleum, chemical, metallurgy, pharmaceutical and other flammable and explosive dangerous places. The design and construction of explosion-proof walls must follow certain specifications to ensure the reliability and safety of their explosion-proof performance. This article will introduce the explosion-proof specifications of engineering explosion-proof walls in detail.
2. Design specifications for explosion-proof walls.
1.Construction of blast walls.
The explosion-proof wall shall be a non-combustible body with a fire resistance limit of not less than 3 hours, and its structure shall be able to withstand the corresponding ** pressure without damage. The explosion-proof wall can be a solid brick wall or a reinforced concrete wall, and reinforced concrete structural columns and ring beams should be provided. An explosion-resistant pressure cover should be set on the wall to relieve pressure when the first occurrence.
2.Selection of materials for explosion-proof walls.
The materials of the explosion-proof wall should meet the requirements of fire resistance, pressure resistance and corrosion resistance, and should have sufficient strength and stability. The wall materials can be steel plates, reinforced concrete slabs, wood boards, etc., but fragile materials such as glass and plastic should be avoided. In addition, the wall material should have good sealing properties to prevent the spread of gases and flames.
3.Arrangement of blast walls.
The layout of the explosion-proof wall should be designed according to the process flow and equipment layout, and the requirements for personnel safety and evacuation routes should be considered. Explosion-proof walls should be set up around the equipment or pipelines that may occur, and safety exits and evacuation channels should be set up to ensure the safe evacuation of personnel.
3. Construction specifications for explosion-proof walls.
1.Preparation before construction.
Before construction, the foundation should be accepted to ensure that it is flat, solid, and meets the design requirements. At the same time, the quality and specifications of the wall material should be checked to ensure that it meets the design requirements and relevant standards. In addition, construction tools and protective equipment should be prepared to ensure construction safety.
2.Quality control of the construction process.
During the construction process, the construction quality should be strictly controlled to ensure that the splicing and fixing of wall materials meet the design requirements and construction specifications. At the same time, waterproof, anti-corrosion, fire prevention and other measures should be taken to ensure the service life and performance of the explosion-proof wall. In addition, attention should be paid to the flatness and verticality of the wall to avoid problems such as cracking and deformation of the wall.
3.Post-construction acceptance.
After the construction is completed, the explosion-proof wall should be inspected to check whether its structure, materials, construction quality and explosion-proof performance meet the design requirements and relevant standards. If problems are found, they should be dealt with and rectified in time to ensure the safety and reliability of the explosion-proof wall.
IV. Conclusions. The explosion-proof specification of the explosion-proof wall of the project is one of the important safeguard measures to ensure the safety of personnel and the safety of enterprise property. In practical application, the design and construction should be carried out in strict accordance with the design requirements and construction specifications to ensure the explosion-proof performance and service life of the explosion-proof wall. At the same time, daily maintenance and management should be strengthened, regular inspections and inspections should be carried out, and problems should be found and dealt with in a timely manner to ensure the safety and reliability of explosion-proof walls.
