| description | The invention belongs to the construction method of a deep foundation pit of industrial construction, particularly relates to a reverse operating construction method of a round deep foundation pit concrete piling support and a main structure and solves the problem that the existing construction method of the deep foundation pit is not suitable for complex geological condition and the construction cost is too high. The construction method comprises the following steps: the center of the foundation pit is adopted as the center and the outer sides of the position of the main structure are respectively distributed with pilings; the top parts of the pilings are poured with crown bore beams which connects the top parts of the pilings into one body; the first section of the foundation pit is excavated, reverse operation is carried out to the outer layer of the first section of the main structure; the outer layer of the first section of the main structure and the pilings are integrated by the crown bore beams so as t |
