Basalt fiber composite pipe of confined concrete column

The invention discloses a basalt fiber composite pipe of a confined concrete column. The basalt fiber composite pipe is characterized in that an upper basalt fiber composite pipe (1), a locking device(2) and a lower basalt fiber composite pipe (3) are included, and the bottom of the upper basalt fiber composite pipe (1) and the top of the lower basalt fiber composite pipe (3) are mounted at the two ends of the locking device (2) in a sleeving mode correspondingly; the upper basalt fiber composite pipe (1) and the lower basalt fiber composite pipe (3) are the same in inner diameter and outer diameter; and the outer diameter of the locking device (2) is gradually increased from the two ends to the middle, and the maximum outer diameter of the locking device (2) is equal to the outer diameter of the upper basalt fiber composite pipe (1) and the outer diameter of the lower basalt fiber composite pipe (3). The basalt fiber composite pipe of the confined concrete column can prevent concretegrout leakage and has the
