[0040] In an embodiment of the present invention, the concrete pier 52 can be inserted into three positioning rods 511 through three positioning holes 521. Of course, the number of positioning rods 511 is not limited to three. Since the triangular distribution is very stable and the required positioning rods 511 are the least, it is optimal to set three positioning rods 511. The rubber layer 522 can provide protection for the top of the concrete pier 52 and reduce the damage rate of the concrete pier 52.

[0041] The spacing between the two connecting plates 51 can be adjusted by the adjusting component 6, so that all the pier components 5 can abut against the bottom of box girders of different models. The adjusting component 6 includes a driving crank 61, a screw rod 62 and a movable slider 63. One end of the screw rod 62 is provided with a docking block 621 that cooperates with the driving crank 61. The screw rod 62 is provided with two sections of external threads with opposite spiral directions. There are two movable sliders 63, and the movable slider 63 is provided with a screw hole that cooperates with the screw rod 62. The top of the I-beam crossbeam 3 is provided with a sliding cavity 33 that slides with the movable slider 63. The screw rod 62 is horizontally rotatably arranged in the sliding cavity 33. The two movable sliders 63 are symmetrically arranged on the screw rod 62, and the two connecting plates 51 are respectively arranged on the top of the two movable sliders 63.

[0042] By driving the crank 61 to be inserted into the docking block 621 of the screw 62, the crank 61 is then rotated to rotate the screw 62. The drive here is not limited to manual, and electric drive can also be used. The screw 62 can be driven to rotate. After the screw 62 rotates, the screw hole can be used to drive the two movable sliders 63 to move relative to each other in the slide cavity 33, thereby adjusting the distance between the two connecting plates 51.

After the rotation adjustment of the connecting plate 51 is completed, the elastic force of the spring 519 can drive the limit plate 518 to move downward, and the limit plate 518 can drive the positioning pin 513 to move downward, and the top of the positioning pin 513 can be inserted into the positioning groove 34. In this way, the connecting plate 51 can be prevented from deflecting at any position of the I-beam cross beam 3 by inserting the positioning pin 513 into the positioning groove 34.

[0045] Furthermore, a first arc surface 514 is provided at one end of the connecting plate 51, and a plurality of chisel grooves 515 arranged at equal angles along its circumference are provided on the first arc surface 514. When the connecting plate 51 cannot be rotated manually, a rod body whose end can be inserted into the chisel groove 515 can be used, and then the tail end of the rod body can be struck with a hammer, so that the connecting plate 51 can be rotated for adjustment.

The two connecting plates 51 are seamlessly spliced ​​together through the cooperation of the alignment columns 516 and the alignment slots 517. All concrete piers 52 can be spliced ​​together as a larger pier. The two beam storage pedestals can be used in combination to support larger box girders.

[0047] The steel body expansion foundation 2 can expand the stability of the connection of the pipe pile body 1 and prevent the pipe pile body 1 from tilting. The steel body expansion foundation 2 includes a connecting ring body 21 and an external support ring body 22. The receiving body 4 is located in the connecting ring body 21, and the receiving body 4 is detachably connected to the connecting ring body 21. The external support ring body 22 is arranged on the outer wall of the connecting ring body 21.

[0049] When the I-beam cross beam 3 is placed on the top of all the receiving bodies 4, the cooperation between the docking ring 32 and the corresponding positioning ring groove 41 allows the I-beam cross beam 3 to be placed in a straight line, thereby avoiding the I-beam cross beam 3 from being skewed and improving the stability of the installation. When the docking ring 32 is inserted into the corresponding positioning ring groove 41, the second wedge surface 321 can contact the first wedge surface 431 of all the telescopic plates 43. The wedge surface cooperation between the first wedge surface 431 and the second wedge surface 321 allows all the telescopic plates 43 to move outward in the telescopic groove 42, that is, all the telescopic plates 43 can extend from the telescopic groove 42 into the annular embedding groove 211. The insertion groove 212 provides movement space for the limit column 44. After all the telescopic plates 43 extend into the annular embedding groove 211, a simple connection is formed between the receiving body 4 and the connecting ring body 21.
