Technical regulations for CAD drawings are based on unified national mechanical drawing standards (such as GB 4457-4460, etc.), and the drawings of solar power generation systems must also conform to national standards unified mechanical drawings. In addition, it is necessary to refer to the electrical standards related to solar energy production systems. You can search online for relevant professional regulations.
What does the letter ① represent in solar panel drawings?
The construction organization design of a solar street light project refers to the formulation of an organization reasonable construction based on the project characteristics and requirements during the implementation of the solar street light project. Plan, clarify construction tasks, construction methods, construction processes and organizational structuren of construction to ensure the smooth progress and high quality completion of the project.
First of all, the design of the construction organization must clarify the construction tasks. Depending on the scale and requirements of the project, determine the scope and content of construction tasks, including the installation of solar street lights, laying of cables, access to electricity, etc. At the same time, it is also necessary to determine the requirements for construction time and construction period in order to reasonably organize the construction progress.
Second, the construction organization design should determine the construction method. According to the characteristics and construction conditions of solar street lights, choose the appropriate construction method, including the selection and use of construction equipment, determination of construction technology.construction, etc. For example, segmented construction can be used to first install solar lighting poles, followed by laying cables and providing electricity access to ensure construction continuity and efficiency.
Third, the design of the construction organization must clarify the construction process. According to the construction tasks and construction methods, a detailed construction process is formulated, including the construction sequence, time arrangement of each construction link, and coordination between processes. For example, carry out the site survey and preparation work first, then carry out the installation of the lighting poles, then carry out the cable laying and access to the power supply, and finally carry out the debugging and reception, etc.
Finally, the design of the construction organization must determine the structure of the construction organizatione construction. According to the construction tasks and construction processes, determine the organizational structure and personnel of the construction team, and clarify the responsibilities and authorities of each construction position. At the same time, construction safety management measures should also be formulated to ensure safety and quality during the construction process.
In summary, the design of the construction organization of a solar street light project is a systematic project. It should comprehensively consider the characteristics and requirements of the project, and reasonably organize construction tasks, construction methods and construction processes. and construction organizational structure to ensure the project progresses smoothly and is delivered to high quality.
