In life, water and electricity are indispensable to us and are essential for our lives. In the renovation, it is necessary to strictly control the construction of hydropower, and its safety and convenience are related to the comfort of everyone's housing. I believe that many people do not understand the hydropower construction plans . What we bring to you today is how to understand the hydropower construction plans and explain the symbols above. How to understand hydropower construction plans 1. Before looking at the hydropower construction drawings, you need to read the design specifications first, and look at the drawings according to the relevant standards above, so that you can understand the overall plan. 2. Look at the structure of the facilities in the drawings. Mark each code of the wall column and floor in the order of the drawings, and then calculate the ratio of the size of the drawings. 3. Take a comprehensive look at the plan, perspective, and section views of the construction site. Compare the site settings with the locations where the three-dimensional changes have occurred. In this way, things that are difficult to understand on the drawings will be understood more than half of them. 4. Finally, check and check again, and mark the shortcomings of the construction on the drawings. In this way, we can more easily understand the hydropower construction drawings. Detailed explanation of symbols on the hydropower diagram 1. The significance of various symbols on the drawings of hydropower The above is a detailed explanation of how to read the hydropower construction plan and the symbol on the hydropower diagram. After reading it, is there more understanding of the hydropower construction plan? In the renovation, you must know how to look at the hydropower construction plan. I hope the above introduction can help everyone.
