Abstract:This paper mainly introduces the practice of safe demolition of two-story steel structures in rural areas. Firstly, the background and necessity of the practice are introduced, and then the relevant contents of the safe demolition of rural two-story steel structures are introduced in detail from five aspects, including design scheme, construction preparation, demolition process, environmental protection requirements and safety measures. The full text covers a wide range and is practical, which helps readers to better understand and master the practical methods of safe demolition of rural two-story steel structures.
1. The background and necessity of the safe demolition of the two-story steel structure in rural areas.
With the continuous advancement of the country's urbanization process, the area of urbanization construction continues to expand, and the number of urban population is also growing, so that the demand for land for urban construction is increasing, and many farmers continue to demolish old houses and build new houses for the sake of livelihood. However, because many rural old houses use steel structures, there are great potential safety hazards, so the safe demolition of rural two-story steel structures has become particularly important.
The demolition of rural two-story steel structure buildings must pay attention to environmental protection construction, especially to prevent noise, dust, harmful gases and other damage to environmental protection. Moreover, it is necessary to develop a detailed construction plan and strictly adhere to safety regulations and standards to ensure the safety and efficiency of the demolition work. Therefore, the practice of safe demolition of rural two-story steel structures is necessary.
2. The design scheme for the safe demolition of the two-story steel structure in the countryside.
The demolition of the two-story steel structure in the countryside requires the development of a detailed design plan. Before the demolition of the steel structure building, the survey and investigation should be carried out first to fully understand the structural characteristics, technical conditions and possible safety hazards and environmental impacts of the building. In the process of inspection and restoration, relevant national and local safety regulations and standards should be strictly observed, and personnel, materials, equipment and technical support should be considered as a whole.
The design scheme includes the following aspects:
1) Determine the construction plan, including the demolition sequence, the demolition method and the demolition equipment, etc.;
2) Determine the construction time, including the estimated demolition time and monitoring time;
3) Determine the construction personnel, including the organizational structure and division of labor;
4) Determine the demolition products, as well as the disposal of waste and waste generated by old buildings;
5) Determine the construction route and mode of transportation.
3. Construction preparation for the safe demolition of rural two-story steel structure.
The demolition of the steel structure requires construction preparation before construction. The preparation for the demolition of the two-story steel structure building in rural areas is not only related to the quality, progress and construction safety of the demolition project, but also related to the impact of environmental protection in the later stage.
The following is an introduction to the preparation for the demolition of the two-story steel structure in the countryside in accordance with the operation process
1) Safety preparations, investigation of safety and environmental protection on the construction site;
2) Equipment and tool preparation, including dismantling machinery, lifting machinery and tools;
3) Prepare the construction site, clean up the obstacles and risk factors around the construction site, and set up a safety isolation belt;
4) Material reserves, including the cleaning and treatment of waste materials and hazardous wastes after demolition.
Before the construction of the project, the construction unit shall propose the corresponding project construction plan according to the characteristics of the project and the relevant laws, regulations and technical standards, and the construction can only be carried out after review and approval. In addition, personnel must also undergo enhanced safety education and training before they can participate in the construction.
4. Demolition process, environmental protection requirements and safety measures for the safe demolition of rural two-story steel structures.
The demolition process refers to the methods and techniques employed in the demolition process. The demolition process of the safe demolition of the two-story steel structure in rural areas should be carried out on the premise of meeting the safety and environmental protection, and the efficiency of the demolition work should be improved as much as possible.
Environmental protection requirements refer to the environmental requirements to be followed and met during the demolition process. For the demolition of steel structures, the generation of harmful gases such as noise, dust, and sulfur dioxide should be avoided. At the same time, there should be corresponding treatment measures for the waste and waste materials after demolition to avoid negative impact on the environment.
Quiet. 
Full measures refer to what measures should be taken during the demolition process to ensure the safety of personnel and the surrounding environment of the construction site. The main measures taken are: division of labor, selection of loading and unloading routes, setting up warning signs and power lines with lightning protection measures. Guarding and protecting steel structures that may hang and fall during demolition.
The demolition of the Barros Group's chemical plant is a very typical example. The demolition work of the chemical plant of Baros Group mainly includes cleaning and replacement before demolition, equipment reduction, sludge reduction, waste liquid treatment, oil tank dismantling, hazardous waste treatment, environmental protection construction, etc., in view of these problems, Barros immovable fire waterjet cutting and demolition technology has been widely used, this technology can not produce sparks, is not easy to cause disasters or disasters, and will not cause harm to the human body, and achieve the purpose of environmental protection and high efficiency.
5. Summary and summary of the practice of safe demolition of two-story steel structures in rural areas.
Through the analysis of the practice of safe demolition of rural two-story steel structures, it can be found that the construction characteristics of rural two-story steel structure safety demolition projects are more significant, and special attention needs to be paid to the current problems of construction. Therefore, in view of the problems that may be encountered in the project, the safe demolition of rural two-story steel structures should focus on the following aspects:
1) Safety and environmental protection are the primary issues;
2) Construction organization and collaboration will affect construction efficiency;
3) The selection of construction equipment and tools can improve the construction efficiency;
4) The demolition process and treatment measures should be rationalized.
In the actual rural two-story steel structure safety demolition construction process, we should closely focus on the above aspects, strengthen the training of construction personnel, strengthen the monitoring of project quality and efficiency, pay attention to the solution of environmental protection problems, and further improve the quality and efficiency of construction, so as to meet the needs of farmers to demolish old houses and build new houses.
