Foundation treatment of 2500m3 blast furnace ironmaking project (including piling works) of Kunming Iron and Steel Co., Ltd. of Wuhan Iron and Steel (Group) Company relocation and transformation and upgrading project to promote supply-side structural reform and implement environmental protection is located in Kunming, Yunnan Province, invested by Kunming Iron and Steel Co., Ltd. of Wuhan Iron and Steel (Group) Company
In total, more than 700 bored piles were completed, with pile lengths ranging from 9.0m to 35.60m, including more than 200 piles with a diameter of 600mm and more than 500 piles with a diameter of 800mm. The stratum surrounding the pile body is mainly composed of prime fill, clay and sandstone. During the construction of the piles, it is necessary to pass through the deepest backfill layer of about 15m, and it is very easy to collapse the holes during the construction of the piles in this stratum.
