One end of the third working channel is connected to the first arc groove 422, and the other end of the third working channel is connected to the first working channel (i.e., the circular through hole 413) of the end core mold 41.

[0040] The second thread column and the second thread groove 442 are used for connection between the core molds.

[0041] The longitudinal reinforcement locking structure 5 includes a fixing ring 51 and a tightening bolt 52. The fixing ring 51 is installed on one end of the end core mold 41 with a circular groove 412 by four fixing screws. The fixing ring 51 covers the entrance of the first working channel (circular through hole 413). There are 16 first screw holes evenly arranged in the fixing ring 51. The 16 first screw holes correspond to the entrances of the 16 first working channels one by one. The 16 tightening bolts 52 are installed in the 16 first screw holes and extend inward from the channel opening of the first working channel (circular through hole 413). There are 16 second screw holes on the inner wall of the circular groove 412. The 16 second screw holes correspond to the 16 first working channels (circular through hole 413). The 16 adjustable bolts 6 are installed in the 16 second screw holes and extend into the first working channel (circular through hole 413). The center position of the bottom of the circular groove 412 of the end core mold 41 is connected to one end of the rotating pillar 2, and the other end of the rotating pillar 2 is connected to the rotating machine 1. The length of the middle core mold 42 is twice that of the additional core mold 44. The fixing bolt 3 is used to install the fixing ring 51 at the entrance of the circular through hole 413 of the end core mold 41. The fixing ring 51 and the tightening bolt 52 cooperate with each other to tighten the two ends of the longitudinal rib 9.

[0042] The tightening bolt 52 includes a second threaded portion 521 and a curved force-bearing portion 522. The curved force-bearing portion 522 is a square concave surface. The screw is vertically connected to the middle of the convex surface of the curved force-bearing portion 522. The second threaded portion 521 can rotate relative to the square force-bearing portion. The second threaded portion 521 can allow the curved force-bearing portion 522 to move left and right, thereby locking or loosening the longitudinal reinforcement 9. The curved force-bearing portion 522 can allow the ends of the longitudinal reinforcement 9 to be concentrated at the lowest point of the curved force-bearing portion 522, thereby avoiding the effect of the end of the longitudinal reinforcement 9 being offset. The adjustable bolt 6 includes a first threaded portion 61 and a strip force-bearing portion 62. The strip force-bearing portion 62 is an arc line. The first threaded portion 61 is vertically connected to the middle of the strip force-bearing portion 62. The first threaded portion 61 can allow the strip force-bearing portion 62 to move up and down, thereby achieving the effect of supporting or lowering the longitudinal reinforcement. The strip-shaped force-bearing portion 62 allows the longitudinal reinforcement 9 to fall onto the strip-shaped force-bearing portion 62 accurately, thereby preventing the longitudinal reinforcement 9 from being offset to the left or right.

[0043] The sleeve 7 includes a tube body 71, two rubber-planted parts 72 and two elastic petals 73. The bottom of the rubber-planted part 72 is connected to the top of the tube body 71. The tube body 71 is installed in the inner cavity of the first arc-shaped groove 422 and the second arc-shaped groove 443. The rubber-planted part 72 extends out of the notches of the first arc-shaped groove 422 and the second arc-shaped groove 443. The diameter of the tube body 71 is larger than the notches of the first arc-shaped groove 422 and the second arc-shaped groove 443, but the overall height of the sleeve is slightly smaller than the diameters of the first arc-shaped groove 422 and the second arc-shaped groove 443. The inner wall of the tube body 71 is provided with a plurality of oblate convex points 75, and the two glue-planting parts 72 form a glue-receiving cavity 78. The front and rear walls of the glue-receiving cavity 78 are provided with stirrup channels 76. The two glue-planting parts 72 are provided with glue-planting holes 74. The left and right sides of the glue-receiving cavity 78 are respectively connected with the glue-planting holes 74. Two elastic petals 73 are installed and connected to the two glue-planting parts 72. The two elastic petals 73 completely cover the top of the glue-receiving cavity 78, and the two elastic petals 73 can be expanded into the glue-receiving cavity 78. The tube body 71 is used to install the longitudinal reinforcement 9. The deviated circular convex points 75 can limit the left and right movement of the longitudinal reinforcement 9 and allow the reinforcement glue to flow from the glue-receiving cavity 78 to enhance the contact between the longitudinal reinforcement 9 and the tube body 71. The glue planting part 72 is used to connect the tube body 71 and the external stirrup 8, the glue planting hole 74 is used to inject the reinforcement glue, the glue cavity 78 is used to accommodate the reinforcement glue, the stirrup channel 76 is used to install the stirrup 8, and the elastic petals 73 are opened into the glue cavity 78 to facilitate the placement of the stirrup 8 into the glue cavity 78 without expanding outward, thereby ensuring the sealing of the glue cavity 78 after the reinforcement glue is injected.
