Liaoning Foundation.
Thread Content
For some reason, it is necessary to build some steel platforms in Liaoning recently. It’s all frozen over here. Right now, the main concern is how to construct the foundation – whether it’s possible to dig it deeper. Assuming that 1.5 meters was dug originally, is it possible to dig to 2 meters or 2.5 meters now? Use cement with a higher grade. Add more water-reducing agents, as well as measures such as insulation and heating. Add a bit more to the pillars. Place a batch reactor with a capacity of 2,000–5,000 in the workshop. Outside the workshop are mainly a falling film absorption tower and a 25-meter chimney. Dig it a bit deeper outside as well, and set up a ground cage directly. What other measures are there?
According to what the original poster said, it’s not a matter of deepening the foundation at the moment; it’s frozen in the northeast, so it’s likely impossible to dig even in the soil. Digging can generally only take place around March or April. If construction can resolve the excavation issue at present, the foundation can be placed below the permafrost layer; the depth of the permafrost is specified in geological surveys, and the foundation depth is outlined in Article 5.1.1 of GB50007-2011.
It’s time to stop working. This isn’t about deepening the structure; the data collected is from a period other than winter. Won’t all those surveys and designs done in winter have to be redone?
