1. Overview.
The engineering explosion-resistant wall refers to the wall structure that can withstand the highest pressure and impact under the action of the first load and prevent the first damage. In petroleum, chemical, mining, metallurgy and other dangerous places where there are high-quality gases, dusts, vapors and other dangerous places, the application of explosion-resistant walls is particularly extensive. In order to ensure the safety performance and stability of explosion-resistant walls, it is necessary to formulate a complete set of explosion-resistant installation specifications. This article will introduce the explosion-resistant installation specifications of engineering explosion-resistant walls in detail.
Second, the type of explosion-resistant wall.
According to different classification criteria, blast walls can be divided into many types. According to the structural form, it can be divided into integral explosion-proof wall and prefabricated explosion-proof wall; According to the materials used, it can be divided into reinforced concrete explosion-resistant walls, steel plate explosion-resistant walls, brick explosion-resistant walls, etc. In practical application, the appropriate type of blast-resistant wall should be selected according to different places and safety level requirements.
3. Explosion-resistant installation specifications.
1.Design requirements.
1) The explosion-resistant wall should be designed according to the risk level, load size, environmental conditions and other factors of the site, and meet the requirements of relevant national standards and specifications.
2) The design of the explosion-resistant wall should fully consider its bearing capacity, durability, stability and seismic performance, so as to ensure that it can effectively withstand pressure and impact when it occurs, and prevent the wall from cracking, deforming or collapsing.
3) For explosion-resistant walls with special structures or special requirements, special design should be carried out, and structural analysis and optimization should be carried out.
2.Material selection.
1) According to the design requirements and bearing capacity of the explosion-resistant wall, materials with sufficient strength and durability should be selected, such as high-quality steel plates, reinforced concrete, etc.
2) The selected material should have explosion-proof performance, which can effectively prevent the damage caused to the wall by the shock wave and debris generated by the first generation.
3) The materials should meet the requirements of relevant national standards and specifications, and have quality certification documents and inspection reports.
3.Construction requirements.
1) Before construction, the foundation should be accepted to ensure that it meets the design requirements, and necessary treatments should be carried out, such as tamping, cushioning, etc., to enhance the bearing capacity and stability of the foundation.
2) According to the requirements of the design drawings, the positioning should be accurately measured to ensure that the position and size of the explosion-resistant wall meet the requirements of the specification.
