[0047] The temporary pier connection device 5 provided by the present invention is used to connect the segment 1 and the foundation 2 of the temporary pier. The fixed pin 12 is driven by the driving device to pass through the first connecting steel plate 10 and then inserted into the pin hole 13 on the second connecting steel plate 7 to achieve the connection between the segment 1 and the foundation 2. The first connecting steel plate 10 can be pre-buried in the segment 1, and the second connecting steel plate 7 can be pre-buried in the foundation 2.

[0048] In the present invention, the driving device comprises:

[0049] Control shaft 4;

[0050] A transmission shaft 9, one end of which is meshed and connected with the control shaft 4, and the other end of which is meshed and connected with the fixed pin 12;

[0051] The control shaft 4 is rotated to drive the transmission shaft 9 to rotate and drive the fixing pin 12 to be inserted into the pin hole 13 .

[0052] In the present invention, the control shaft 4 includes:

[0053] A connecting rod 18 is provided with a control knob 17 at one end and a control gear 16 at the other end.

[0054] In the present invention, the transmission shaft 9 comprises:
