Embodiment Construction
[0042] The present invention will be further described below in conjunction with embodiment and accompanying drawing. The invention is a fiber-reinforced composite material pipe-constrained cement-based composite material-reinforced pier column structure, such as figure 1 As shown, it mainly includes a pier column, a fiber reinforced composite material base 4 arranged at the bottom of the pier column, a fiber reinforced composite material tube 2 arranged around the pier column, and filled between the fiber reinforced composite material tube 2 and the pier column Between the cement-based composite material 3 for engineering, the lower end of the fiber-reinforced composite material base 4 is fixedly connected to the pier through a compressible sealing strip 5, and the upper end is fixedly connected to the pier through a stopper 1. The limiter 1 includes a screw rod 12, a ferrule 13 fixed at one end of the screw rod 12, a top plate 8 fixed at the other end of the screw rod 12, a...
