Some more context might help. Here is a video from 1929, in which one can see the bamboo poles tied together.

Here are some images from the ACK rendering of Uggasena's tale. As well as some images from a book on India from the 19th century and some photos from the 20th century. The ACK images look more like a contemporary mallakhamb pole made from teak or rosewood than the bamboo poles clearly used in the photos and mentioned in primary sources. In the photos, the poles seem approximately 4–5 meters long. 27 meters just seems wildly inaccurate.
